Description

The system that is used for the energy distribution of Long-distance Control local sites

The application is that the name of submitting on November 27th, 2002 is called: the dividing an application of the one Chinese patent application 02827684.1 of " system that is used for the energy distribution of Long-distance Control local sites ".

Technical field

Relate generally to of the present invention is used to control the system and method for the energy distribution of local sites.

Background technology

Electric industry is faced with special challenge in the user load demand side that satisfies constantly variation.At least there are two relevant reasons for these challenges.At first, electricity needs can fluctuate from one day to another day or from one hour to another hour significantly, and it is very difficult to make electric industry guarantee that they have enough abilities to meet the demands.Fluctuation on these energy requirements can be because daily circulating energy application model (the following period of the day from 11 a.m. to 1 p.m for example occurring the peak); Or because the unexpected change on the energy supply and demand balance; For example; The generator of linking on the electrical network quits work, and big energy user is reached the standard grade or rolled off the production line, or in distribution system, breaks down.

The power consumption that second factor of the challenge that electric industry faces is regional area is tended to increase in time, thereby is the electric industry burden that satisfied ever-increasing increase in demand gradually.Because the construction of new power plant is very expensive, and must meet multiple government regulation, so a place and even big geographic area can find oneself not have power capacity current maybe can expect following demand to supply it.

A main challenge of utility companies is to handle the peak energy demand.This is because the energy of electric industry supply must enough satisfy different energy requirements constantly, and the peak energy demand has applied maximum pressure to electric power distribution system.When energy requirement surpassed effective supply, destructive incident just possibly take place like power failure (blackouts), power shortage (brownouts) or temporary interruption (interruptions).Such incident not only causes suitable inconvenience to a large amount of people and commercial undertaking, and is dangerous or life-threatening, and for example the supply of electric power of hospital or crucial care and household Medical Devices suffers damage.

In history, face because during serious energy situation that high demand causes, their selection is extremely limited when the electric industry in a zone of service.For example, electric industry can require the user to save energy, but not every user accepts such requirement, in any case and save and can not total solution be provided for the energy supply problem.Electric industry can be attempted through buying effective energy from third party's energy of linking electrical network to satisfy peak demand, and still such purchase in peak demand constantly, is very expensive, because energy supply company requires extra charge usually when demand is high particularly.Another selection of electric industry is to build extra power plant, but building the power plant wants long time and a large amount of investments, and needs the approval of state and/or federal government and user federation.

In order to reduce the peak value electricity needs; Avoid buying relevant cost with new power plant and additional energy; Made different trials with the exploitation load management system; For avoiding having a power failure or when similarly power breakdown was necessary temporary close certain user load, load management system controled the peak demand to energy generation equipment through this.Usually, the user load type of regulating in such a way comprises nonessential electric equipment, like air-conditioning, electric heater or the like.

For example, a kind of load management system uses the ripple tone to inject (ripple tone injection) and on public power wire, sends coded pulse.This coded pulse can be applied on the public power wire through dynamo-electric ripple control reflector or step-up transformer; Wherein dynamo-electric ripple control reflector is by forming through the motor of controllable silicon static switch work; Step-up transformer is connected on the public power wire through band-pass circuit selectively, band-pass circuit by be tuned to the coded pulse signal frequency.At the user place, receiver is resolved coded pulse and is carried out required command functions---as close user load.

United States Patent (USP) 4,264,960 have described the example of a load management particular system.Of this patent, under the control of main control station, unit launching code pulse signal on public power wire is injected in a plurality of substations.Be positioned at the remote receiver at user load place, response is received on the public power wire signal that injects the unit from the substation, and can connect and the state that turns on and off of control load by sealed one pole through excitation.Dissimilar loads is organized into (like electric water heater, compressor of air conditioner, street lamp etc.) in the load control group.Main control station is controlled a plurality of dissimilar loads independently through the different pulse control signal.Each remote receiver unit is by precoding, so that respond a unique pulse code signal.In order to control the dissimilar load of same position (like hot-water heater and compressor of air conditioner), need be in the remote receiver of the absolute coding of this position.Main control station turns on and off load group, so that the determined load management strategy of executive system operator.

The conventional art that is used for extensive electric power distribution system load management exists multiple shortcoming and restriction.Major defect is that the same power supply above-the-line promotion of high-tension electricity is being carried in the shutoff order from the electric industry to the remote user sites.Because use the relaying signal of telecommunication of transformer on power line, transmit data on the power line (like interruptive command or other control signals so be difficult in.And noise or disturb and to hinder the correct reception of turn-offing order or other control signals.Any induction of user load can produce big harmonic wave, this harmonic wave maybe be easily and the control signal frequency be complementary, so just hindered control signal maybe possibly cause " false alarm ".Simple housed device such as electric furnace just can destroy the reception of the control signal on the power line.In a big zone, because all loads all can be incorporated into noise in the electric power distribution system, the interference of accumulation or The noise are significant.Therefore, owing to have a lot of noises and interference source, use power line distribution control signal possibly have very big problem.Can use the Digital Signal Processing of complicacy to come filtered noise and interference and reconstruct control signal, but such technical sophistication and the common receiver that needs costliness.

Another shortcoming that is used for the conventional art of load management is to lack electric industry level or user class control.In order to prevent that peak demand from causing calamitous the power failure or generation of damage electric power or distributing equipment; The compelled electric power (for example through have a power failure (rollingblackout) that roll) that turn-offs one or more zones of electric industry; In this case, power consumer seldom control or not control load minimizing usually.Certainly, for the user in the rolling power supply interrupted district, the situation of turn-offing custom power fully usually can occur.Electric industry is pre-configured subscriber's line; So that dynamically reduce some isolated load (normally air-conditioning or electric heater) constantly at peak value electric power; Even but in this case,, reduce otherwise electric industry and user can not easily change load only if reconfigure subscriber's line.Only integrally be grouped into the place of different load control groups at user load; Electric industry can reduce the load (like all air-conditionings) of some type together; But this selects electric industry normally to make based on its whole electricity needs and management strategy; The user has only very little control or does not control (rather than like this; Before the pre-configured circuit of electric industry is with the certain loads of control as a part of bigger group of similar load, give the authority that electric industry turn-offs certain loads, for example an air-conditioning unit) in advance.

Another problem that the conventional load administrative skill fails fully to solve is that temporary interruption, power shortage or power failure take place under the situation that power consumer seldom or not obtains warning usually.Can predict under some situation of very large demand, electric industry can warn power consumer to have a power failure or temporary interruption possibly take place in coming certain time period---for example at subsequently several hrs, or in subsequently 24 hours or 48 hours.Yet the temporary interruption or the warning that has a power failure are actually so extensively with ambiguous usually, so that concerning power consumer, are worth limited or and be not worth, and whether these users break to their electric power, and as resolutely fall be again when break all uncertain.And, be not easy to loss warning and can not recognize temporary interruption or have a power failure coming because the user of radio or television, is listened in the temporary interruption or the warning that has a power failure normally through radio or television broadcasting.

Proposed the power consumption that some electrical management technology is used to control specific local sites (like factory), but such system is normally isolated, and is independent of the electric industry operation.For example, at United States Patent (USP) 4,216, the example of an electric power management system has been described in 384.According to wherein said representative art, a plurality of main power lines in device or place are monitored to obtain the energy operating position, when the gross energy that installs or the place obtains surpassed the maximum of regulation, control circuit is disconnecting consumers selectively.Though the electric power management system of these types has obviously reduced the total electricity consumption in said device or place, its shortcoming is that they maybe relative complex and costliness.For example; United States Patent (USP) 4; 216; 384 electric power management systems described utilize one group of transformer to monitor a plurality of main power lines independently, and one group of trigger triode (LED-triggeredTriacs) that LED triggers is adjusted circuit or the like again so that connect a plurality of user loads, programmable control circuit, automatic priority level selectively.Because they are relatively costly and complicated, the local power management system of these types is not to be well suited for large tracts of land to use, and especially the ordinarily resident is used the application with other cost sensitivities.And in fact very localization of their operation can not be controlled from centers such as electric industries self.

Except foregoing restriction and shortcoming, traditional electric power and load management strategy receive the restriction of available circuit and switch, and these circuit and switch are used in some application and carry with the actual electric power that is controlled at local sites.For example; Power supply is connected with load and the power switch of a kind of general type of breaking off is a circuit-breaker, and its function is, when reaching current limitation; Circuit-breaker prevents that through the circuit paths between deenergization and the load overcurrent from obtaining or flowing into load from power supply.Typical circuit-breaker has the bimetallic arm, can electric power signal be sent to load from power supply through this bimetallic arm.One end of bimetallic arm is linked the electric power signal line, and the other end of bimetallic arm is linked electric conductor, can be with distributing electric power to load through this conductor.When too many electric current flow through the bimetallic arm, electrical current heat caused bimetallic arm distortion or crooked in a predetermined manner, like this bimetallic arm and electric conductor contact disconnection, cause electric power signal and load disconnection.By this way, protection power supply and the load infringement of electric current of avoiding transfiniting.

Though circuit-breaker is preventing that aspect the high levels of current be useful, they are passive electric circuit element normally, and its response is decided by the amount of power that load is obtained fully.They can not provide the ACTIVE CONTROL to the electric power signal line usually.Yet some circuit interruption device that can reset is suggested, and for example, it utilizes spring operating mechanism to allow the connection of teleoperator's disconnection or closed circuit interrupter.The United States Patent (USP) 3,883,781 of authorizing J.Cotton discloses the example of such circuit interruption device.

Also being illustrated of the Long-distance Control of other types or the circuit interruption device of operation, as the United States Patent (USP) 5,381,121 of authorizing people such as Peter and the United States Patent (USP) 4,625,190 of authorizing people such as Wafer.These circuit interruption devices comprise more exquisite mechanism, and these mechanisms make more costliness, and possibly receive mechanical wear or fault owing to their complexity.

Except circuit interruption device, the circuit of other types has been used to control electric power signal.Yet the circuit of these other types also has shortcoming.For example, in order to control the distribution of the electric power signal that is transported to load, solid-state switch (like the rectifier (SCRs) of transistor or silicon control) can be used as the switch between power supply and the load.Yet transistor and SCRs have limited rated power usually, when high levels of current, can be damaged or short circuit.And the transistor of high rated power or SCRs are more expensive relatively.

Therefore, provide the load management system that overcomes aforementioned one or more problem, restriction or shortcoming to have superiority.Provide electric industry and/or user to have noise and load management system interference effect, that do not need your recipient bigger flexibility, that not caused by the emission data and have further advantage.The load management system that uses controllable electronic switch is provided; Especially provide reliable, durable and cheap switch also to have superiority; Wherein controllable electronic switch can be connected power supply selectively with load or breaks off, they can processing such as resident or application need for a business higher relatively electricity needs.

In operation, wirelessenergy control unit 214communication interfaces 235 receive, and if desired, resolve and/or temporary transient memory command or other message, and these orders and message receive from remote transmitter through communication unit 215.Communication unit 215 can dateout, and the form of these data depends on wireless communication technology or the agreement that is adopted, and the complexity that receives electronics.For example, when message when long-range emission source receives,communication unit 215 can multiple interval output digital data bitstream.Communication interface 235 can be resolved from the data ofcommunication unit 215 outputs, and for example, can be that effectively which data is to send to specific wirelessenergy control unit 214 through being configured to discern which data.Message from long-range emission source (like central station 102) emission; As will further specifying here; Can be addressed or encode, so as to have only some wireless energy control unit (as, those are in specific geographic area) response (react) order and the message seen off.

When message arrived withcommunication interface 235 througheffective communication unit 215,processor 230 can be through the message of any suitable device consciousness reception.For example,processor 230 can receive interrupt signal fromcommunication unit 215, or regularly wheelnews communication unit 235 arrives to have determined whether message.In certain embodiments; For conserve energy; Allowprocessor 230 and other control circuits " sleep " state that is placed in to have superiority, wherein through the power supply of disconnection of wirelessenergy control unit 214, the circuit of wirelessenergy control unit 214 turn-offs basically; Exceptcommunication unit 215 andcommunication interface 235 and other basic circuit, if any.Whencommunication interface 235 is checked through message bycommunication unit 215 receptions; Perhaps according to some incident that should be noted that (like the sequencing that is provided with, display update, periodic status checkout etc.); Specific internal electric source management circuit (not shown) can be carried out the operation that connects power supply again, and this operation can activate or " waking up "processor 230 and other control circuits again.By this way, when response command not or when carrying out some other required activity, wirelessenergy control unit 214 can be only with minimum electric power.

Be apprised of from remote transmitter whenprocessor 230 and received emission,processor 230 is attempted any order that has received of response or other message.The response ofprocessor 230 is usually according to some stored parameters with in other configuration messages or the programmed instructions of wireless energy control unit 214.In this,memory 239 can advantageously be made up of Different Logic and/or physical piece, comprises workingstorage part 243,program storage portion 242 and parameter storage area 241.Usually, programcommand storage area 242 comprises nonvolatile memory (like EEPROM) withparameter storage area 241, andworking storage part 243 comprises volatile memory (like RAM).In certain embodiments,memory 239 also can have subsequent use DC power supply (like battery), loses just in case main power source helps to prevent stored message when cutting off the power supply temporarily.

Be stored in the program command of programcommand storage area 242, the parameter that is stored inparameter storage area 241 and/or switches set orloader 238 orders that receive from the remote message source of 214 pairs of regulation wireless energy control units or the response of other message basically are set; Rule or logic integrally are provided; Through this rule or logic, wirelessenergy control unit 214 confirms that which gate-controlledswitch 262 breaks off or connection again.In a preferred embodiment, wirelessenergy control unit 214 is that the user is configurable, so that gate-controlledswitch 262 breaks off or the order of connection again can be confirmed separately each local sites 109.In one aspect, in certain embodiments, wirelessenergy control unit 214 provides the ability of setting up priority orders, and gate-controlledswitch 262 breaks off with this priority or connects.But priority through manual adjustment a plurality of switches orloader 238 be set set.Switch orloader 238 is set adopts arbitrarily wide kind form.For example, each gate-controlledswitch 262 can be relevant with the multiposition switches (not shown), and this multiposition switches provides switch or in theloader 238 is set.Each position of multiposition switches can indicate whether that the gate-controlledswitch 262 of being correlated with will respond the warning stage triggering of specified level, like the detailed description of back.For example; In the system of three possibilities of existence warning stages; Multiposition switches can have four positions, wherein three corresponding phase I, second stage and phase III alarm conditions, and the 4th the position relevant gate-controlledswitch 262 of indication will not respond any in three warning stages.The position of the switch number of multiposition switches can be confirmed by the number of possible warning stage, confirm at least in part.

Perhaps, but the response of 262 pairs of a plurality of warning stages of gate-controlled switch is software programizations, uses a plurality of button/switch loaders (it can be to provide as a switch or a part that loader 238 is set) to dispose the priority orders of gate-controlled switch 262.Just the same with an example, allow the user to circulate to carry out a routine, each gate-controlled switch 262 of this routine sequential addressing and for each gate-controlled switch 262 allows the user that the situation of warning stage is imported required response.The message of sequencing can be shown in the visual display unit (in Fig. 2, they are generally with 236 representatives of display/indicating device) of little LCD display or other types.Wireless energy control unit 214 has a group-indicate device (in Fig. 2, vivo being represented by display/indicating device 236) indication alternatively, and on indivedual bases, gate-controlled switch 262 if having, breaks off in the given moment immediately.For example, such indicating device can comprise LEDs or other small-power optical elements.Display/indicating device 236 can be indicated (for example through special LED indicating device, or flashing message or the seasonable sound of hearing on the little LCD display), and it is coming that " early warning " message that has received from central station 102 indicates power alarms.

In certain embodiments, wirelessenergy control unit 214 is configurable to have the programmable timer function, allow to adjust the priority that electrical load breaks off automatically based on certain time-giver, for example, and in the week specific one day, specific moment or the like in one day.Such timing can be by user program, and its mode will be broken off according to the reception of the message that requires fromcentral station 102 to do like this through its gate-controlledswitch 262 as setting the initial priority scheme.But theparameter storage area 241 memory timing parameters ofmemory 239, its priority able to programme that causes gate-controlledswitch 262 changed in thespecific time.Memory 239 can immediately write down the state of a plurality of gate-controlledswitches 262 constantly through configuration in difference, or the other system parameter.In certain embodiments,memory 239 can be triggered with recording messages after incident only, and this incident causes that one or more electrical loads are disconnected, or some other incident with importance.

As further specifying among Fig. 2, control register 237 is used to store current " order " state that is used for gate-controlled switch 262.In certain embodiments, for example, each position of control register 237 can keep command bit, and its binary condition (" 1 " or " 0 ") indicates the open/close state of relevant gate-controlled switch 262.Wirelessenergy control unit 214 also can be used to control other sources of regional area---for example, and gas pipeline closer 290.Similarly, the mechanism that is used for gas pipeline closer 290 can have relevant open/close state/command bit at control register 237.

Fig. 3 is the view that some element physics of explanation is settled, and these elements are used among the embodiment of local energy control system.As shown in Figure 3, wireless energy control unit 370 can physically be fixed or be placed in the circuit box 300.Circuit box 300 can comprise one group of ON/OFF or reset switch 351, and it is used for manual reset electro circuit breaker (as be shown in Fig. 2 circuit-breaker 251) and/or is used for based on single reason, breaks off being connected to the electrical load on the particular electrical circuit circuit breaker.Switch 351 among Fig. 3 illustrates with a plurality of open and closed.From circuit-breaker, the output line that is used to link a plurality of electrical loads can pass through 370 draws of wireless energy control unit, connects through a plurality of gate-controlled switches (as being shown in the gate-controlled switch 262 among Fig. 2) particularly.In specific embodiment illustrated in fig. 3, wireless energy control unit 370 also illustrates with one group of hand switch 372, and which gate-controlled switch it is used to select to respond long-range electrical management instruction of sending and normal priority wherein.If have only a power alarms stage to be used by electric power management system 100; Hand switch 372 can be only with two its functions of position of the switch performance so; First position indicates gate-controlled switch and in the input of power alarms stage, does not turn-off (promptly breaking off its electrical load), and second position indicates its shutoff in the input of power alarms stage.

Another aspect, if electricpower management system 100 has graduate power alarms groups of phases, so more complicated switch is provided with group and may be utilized.For example; If three power alarms stages are used to electricpower management system 100 and (do not comprise " power failure " stage or other warning stages; Wherein do not relate to the local power control circuit), eachhand switch 372 can have four positions so, and which power alarms stage of first three position indication (promptly breaking off its electrical load) before corresponding gate-controlled switch will turn-off is necessary; And the 4th position indicates corresponding gate-controlled switch not turn-off, to respond any power alarms stage.The 4th position is useful to the management electrical load, and the user thinks that the management electrical load is crucial, so break off if can avoid not hoping.

The optical indicator (like LEDs) 373 of contiguous eachhand switch 372 can be used for indication; Whether any gate-controlled switch has in fact broken off their electrical loads separately; With the message of response from central station; This central station makes wirelessenergy control unit 370 input power alarms stage ranks, and its requirement or request local power reduce.Display and/orinterface 371 can be used to provide text message; Be pre-stored in the wirelessenergy control unit 370, or receive, perhaps from central station; If button or suitable device provide, with a plurality of functional programsization that allow wirelessenergy control unit 370 to provide.

As the front be shown in embodiment among Fig. 2 pointed; Wireless energy control unit 370 (and therefore; Gate-controlled switch) can be positioned in the downstream or the upper reaches of circuit-breaker switch 351; Because under which kind of situation, wirelessenergy control unit 370 can both work, so that break off the input power cord from the partial electrical load.In one aspect; Wirelessenergy control unit 370 provides compact, effective and practical device to regulate local power consumption; This is minimum intrusion to user site; Because it can integrate with thecommon circuit box 300 or the electrical box of similar size, therefore only need carry out minimum change to existing utility.

In interchangeable embodiment, wirelessenergy control unit 370 can connect with fuse place with circuit-breaker relatively or append on it.

In a plurality of embodiment; Electric power management system 100 is on the time of endless; Through sending order from central source (being central station 102); Operation to be reducing or to limit total custom power demand, and this order makes the control circuit power 112 at local sites 109 individually break off selected electrical load 120.In a preferred embodiment, central station 102 maintains the power demand of necessary minimizing in the tolerable restriction based on the running with electric industry 105, sends the declaration of power alarms stage.According to an example, be electric power management system 100 definition one or more power alarms stage ranks, and central station 102 pass through the wireless communication unit 115 of broadcast warning rank to a plurality of local sites 109 wirelessly, change power alarms stage rank.Along with the custom power increase in demand to the threshold level of taking to move, central station 102 broadcasting and ranks of corresponding power alarms stage of the present situation.Along with the custom power demand is reduced to more tolerable level, central station 102 just can be broadcasted power alarms stage rank, and it indicates some or all electrical loads 120 and can be connected.Announce total custom power desired level of different electric power stage alarms, can be fixed on the specific threshold level or on the particular percentile of total electricity capacity (it dynamically fluctuates---as with the date, with hour, or even quickly).Replacedly; The power alarms phase messages can respond manual command and send; This manual command is through personnel's input of the mandate relevant with electric industry 105 and/or central station 102, allow people's adjustment can get into decision-making like this, or use is automatic and the combination of manual technique.The power alarms stage rank of any number may be utilized, and it depends on the desired complexity of electric power management system 100.

According to an example; Electric power management system 100 can have four power alarms stage ranks---and wherein three cause that local sites 109 reduces the orders from central station 102 that their power consumption are received with response, and the 4th power alarms stage grade requirement taked extra step (like the power shortage of having a mind to or the power failure of certain geographic area).The state diagram 1100 that Figure 11 changes between the stage according to such example, a plurality of power alarms of explanation.Shown in figure 11, state diagram 1100 comprises a plurality of states of 1105 to 1109, and they are corresponding to different power alarms stage ranks.When total custom power demand (be the first threshold level that total custom power desired level is lower than regulation, this level is designated as LEVEL1) in tolerable scope, electric power management system 100 remains on non-alarm state 1105.When total custom power surpasses the first threshold level (like LEVEL1), electric power management system 100 gets into phase I alarm states 1106, so central station 102 broadcast radio message are to local wireless communication unit 115, and its indication phase I power alarms has been announced.As response, break off a plurality of partial electrical loads 120 selectively at the control circuit power 112 of local sites 109, therefore reduce total user's request to keep total energy usage in tolerable level.Electric industry 105 can be measured the degree that electricity needs reduces, and transmits this message to central station 102 (or other processing centers), for confirming of later power alarms stage rank.For example central station 102 (or other processing centers) can be current total electricity needs level as comprising that sending the power alarms stage warns the amount of the total electricity needs level reduction that is caused to handle; Owing to cancel the connection again that the warning of power alarms stage just is considered to cause previous partial electrical load 120 of breaking off at any time, and therefore increase total electricity needs.Therefore, total custom power level and a plurality of threshold level are relatively the time in being shown in Figure 11, and electric power management system 100 is preferably taken into account the influence of breaking off partial electrical load 120.

As long as total custom power demand remains on the first demand threshold LEVEL1, but under the second demand threshold LEVEL2, electricpower management system 100 remains on phase I alarm state 1106.Yet; If total custom power demand continues to increase; So that surpass the second demand threshold LEVEL2; Electricpower management system 100 just gets into second stage alarm state 1107, andcentral station 102 wirelessly broadcasts a piece of news to thewireless communication unit 115 of a plurality oflocal sites 109, indicates the warning of second stage power alarms and announces.Yet; On the other hand; If total custom power demand falls back to below the first demand threshold LEVEL1, electricpower management system 100 turns back to non-alarm state 1105, socentral station 102 is wirelessly broadcasted thewireless communication unit 115 of a piece of news to a plurality oflocal sites 109; Indicate phase I power alarms no longer valid, electricpower management system 100 turns back to non-alarm state 1105.

As long as total custom power demand remains on the second demand threshold LEVEL2, but under the 3rd demand threshold LEVEL3, electricpower management system 100 remains on second stage alarm state 1107.Yet; If total custom power demand continues to increase; So that surpass the 3rd demand threshold LEVEL3; Electricpower management system 100 is just imported phase III alarm state 1108, andcentral station 102 wirelessly broadcasts a piece of news to thewireless communication unit 115 of a plurality oflocal sites 109, indicates phase III power alarms warning and announces.Yet; On the other hand; If total custom power slump in demand is below the second demand threshold LEVEL2, electricpower management system 100 turns back to phase I alarm state 1106, socentral station 102 is wirelessly broadcasted thewireless communication unit 115 of a piece of news to a plurality oflocal sites 109; Indicate second stage power alarms no longer valid, electricpower management system 100 turns back to phase I alarm state 1106.

Similarly, as long as total custom power demand remains on the 3rd demand threshold LEVEL3, but under the 4th demand threshold LEVEL4, electric power management system 100 remains on second stage alarm state 1108.Yet, if total custom power demand continues to increase, so that surpassing the 4th demand threshold LEVEL4, electric power management system 100 is just imported stage alarm state 1109, so take extra step (having a power failure or power shortage like regionality).Wireless command is not essential in this case; Yet if desired, power failure or power shortage alert message can be by central station 102 transmission, so that the user of local sites 109 can obtain alarm before power failure or power shortage generation.Selectively; Central station 102 can be transmitted in and have a power failure or power shortage time proximity amount before; And the time before upcoming power-off event can be shown by local power control circuit 112, so that the user can take following of this situation to want any measure of taking.Below total custom power slump in demand to the three demand threshold LEVEL3; Electric power management system 100 turns back to second stage alarm state 1107; So central station 102 is wirelessly broadcasted the wireless communication unit 115 of a piece of news to a plurality of local sites 109; Indicate phase III power alarms no longer valid, and electric power management system 100 turns back to second stage alarm state 1107.

As the interchangeable mode that can realize similar results, can use single electric power to utilize threshold value, because of responding the custom power demand that each power alarms stage rank descends, when calculating next power alarms stage rank, needn't consider.According to this interchangeable embodiment, along with each power alarms stage is announced, total custom power desired level is expected to owing to the entire effect at a plurality of energy control units 114 of a plurality of local sites 109 descends.Therefore identical electric power utilizes threshold value to can be used for each power alarms stage rank, lets electric power management system 100 have favourable operation simultaneously.For example, electric power utilizes threshold value can be set at 96% of total electricity capacity.Utilize threshold value when total custom power demand reaches electric power, phase I power alarms alert message is transferred to wireless energy control unit 114, and it breaks off some electrical load 120.As a result of, the total custom power demand certain amount (for example, 5%) that will descend.Electric power utilizes threshold value can remain on 96% of capacity.In the first power alarms stage rank, when total custom power demand reaches 96% again, central station 102 can be launched second stage power alarms alert message to wireless energy control unit 114, therefore causes another decline of total custom power demand.This circulation can repeat to get into the third and fourth power alarms stage rank.

Process 1100 can be carried out in the system of automation, and for example, this system uses one or more computer processors to carry out with centralized or distributed structure/architecture, and it can be positioned at central station 102 or other places.At the threshold level programmable of a plurality of power alarms between the stage.Can use hysteresis technology, with convenient custom power demand near the threshold level time, system is quick oscillation back and forth between two different warning stage ranks not.In other words, when the custom power increase in demand, the threshold level is added a hysteresis; In case the custom power demand surpasses threshold level (adding hysteresis); Just get into a new warning stage rank, the threshold level is deducted a hysteresis, so that when the user's request level reduces; In order to switch back lower power alarms stage rank, the custom power demand need drop to below the threshold level that deducts hysteresis.In addition; Because expectation switches to and can cause that total custom power demand descends fast after next power alarms stage rank and (be used for total custom power desired level that the power alarms stage calculates and go to relax this effect although slippage is added to; As stated); The technology of hysteresis is preventing that local sites 109 from reducing their selected electrical loads 120 at the beginning, and it is useful that last power alarms stage other aspect of level is just switched go back to fast in system.

Use technology illustrated in fig. 11,electric industry 102 can dynamically be controlled total custom power demand, thereby reduces peak user power consumption when avoiding energy crisis necessary.Through a plurality of warning stage ranks are provided, such electrical management technology has reduced the granularity of selecting user's electric weight, and burden for users is dropped to minimum degree.

With the further specifying of mode of breaking off or connect gate-controlled switch about multiple local power control circuit for the effective local power consumption of control selectively is provided.This explanation will concentrate on the embodiment of local energy control system 200 shown in Figure 2, but principle and notion also can be applied to other embodiment.Suppose the different power alarms stage that defined in the electric power management system; Where topical energy management system 200 receives message and gets into the highest power alarms stage of the next one; Wireless energy control unit 214 is checked switches or loader 238 is set and/or stored parameters 241, so that confirm that which gate-controlled switch 262 is disconnected.In this example; Switch or loader 238 is set is that (each position of the switch is corresponding to the power alarms stage like foregoing multiposition switches wherein; Corresponding gate-controlled switch 262 responds through the electrical load that reduces separately on corresponding electric power warning stage) form; Processor 230 can check simply that the position of each multiposition switches is provided with, and will be set at the position of disconnection so that break off electrical load separately to determine whether corresponding controllable switch 262.For example, when indicating wireless energy control unit 214 to get into first power alarms during stage from the message of central station 102, whether the switch setting of processor 230 each multiposition switches of inspection indicates the first power alarms stage of response to confirm the position of the switch.When the message indication wireless energy control unit 214 from central station 102 gets into second power alarms during stage; Whether the switch setting of processor 230 each multiposition switches of inspection indicates the first power alarms stage of response or the second power alarms stage to confirm the position of the switch.When the message indication wireless energy control unit 214 from central station 102 gets into the 3rd power alarms during the stage; Whether the switch setting of processor 230 each multiposition switches of inspection indicates the first power alarms stage of response, the second power alarms stage or the 3rd power alarms stage to confirm the position of the switch.Under every kind of situation, confirm that when processor 230 gate-controlled switches 262 should respond current power warning stage rank, processor 230 sends the appropriate command in the control register 237, and it causes that successively corresponding gate-controlled switch 262 opens and break off its electrical load.

In alternative embodiment, switch orloader 238 is set indicates the relative priority level of breaking off gate-controlledswitch 262 is with the remote command of response from central station 102.In such embodiment, can use the power alarms stage of indefinite number.When the message that received for the first power alarms stage (or electric power reduce order), the gate-controlledswitch 262 with lowest priority breaks off, and therefore its electrical load also breaks off.By each power alarms phase messages (or electric power reduces order) subsequently, the gate-controlledswitch 262 of next limit priority breaks off, and up to a maximum, all gate-controlledswitches 262 break off.Yet, switch orloader 238 is set also can indicates some gate-controlledswitch 262 to remain closed continuously and never break off, for example theseswitches 262 can be corresponding to key or important electric equipment.

Replacedly; If wirelessenergy control unit 214 is linked the output reading from the local power meter; So that dynamically monitoring how much electric power is used by local sites; Wirelessenergy control unit 214 can be by indication (directly or indirectly), and perhaps pre-programmed is to reduce local power consumption by specific percentage or specified quantitative.214 pairs of electrical loads that will reduce of wireless energy control unit and the gate-controlledswitch 262 that will break off when initial are made one and are initially confirmed (for example according to above-mentioned technology).Wirelessenergy control unit 214 can be monitored local power and use to confirm whether extra gate-controlledswitch 262 needs to break off, to reach palpus the target energy usage level or the target level maintenance energy use of palpus.Wirelessenergy control unit 214 can or be provided withloader 238 indicated priority according to switch and break off extra gate-controlledswitch 262.

Along with other reduction of level of power alarms stage, wirelessenergy control unit 214 can closed gate-controlledswitch 262, thereby according to being connected electrical load again with order that gate-controlledswitch 262 breaks off reversed in order.Wirelessenergy control unit 214 if desired, can postpone in a period of time that adds by force between the connection again of any two gate-controlledswitches 262, to reduce electric power spike or similarly harmful effect.

Figure 12 and 13 is the process charts according to two different embodiment disclosed herein, and a plurality of steps of between different warning stages, changing have been described.For simplicity, contrast electric power management system embodiment shown in Figure 1 describes the processing procedure in Figure 12 and 13 below, but it should be understood that this principle and notion also are applicable to other electric power management system embodiment.At first forward Figure 12 to, theprocessing procedure 1200 according to the electrical management of first embodiment has been described.In processing procedure shown in Figure 12 1200, suppose thatcentral station 102 confirmed, can make such decision based on this condition, message is wirelessly transmitted to a plurality oflocal sites 109 so that adjust their power consumption (or, under certain conditions, be used for other purposes).Therefore, in thefirst step 1201,central station 102 is through thewireless communication unit 115 of itswireless communication unit 103 emission message (or a series of message) to a plurality oflocal sites 109.

Wireless transmit from central station 103 can adopt any one in the various ways.For example, wireless transmit can comprise the broadcast transmission of wanting all local sites 109 all to receive.Replacedly, also can comprise the broadcast transmission of only wanting certain specific local sites 109 to receive.In this respect, if desired, can be according to any logical criteria, for example geographic area, resident/commerce (possibly have different residents and/or commercial subclass), average consumption etc. or their combination in any are arranged into different groups with local sites 109.Central station 102 can be indicated the local sites 109 of this group through the broadcast of passing to particular group.For example, can be unique group address of each set of dispense or group instruction code, each local sites its unique group address of 109 responses or the group instruction code of local sites 109.Replacedly; Or extraly; Can be unique frequency band of each set of dispense or subband or a unique encoding scheme of local sites 109, each local sites 109 let its wireless communication unit 115 by be tuned to its unique frequency band or subband or be configured to and receive message and message is decoded according to its encoding scheme.By this way, central station 102 has the electrical management flexibility of increase, allows the group of central station 102 orders all or any local sites, with restriction power consumption.An advantage as such arrangement; Central station 102 can only be ordered some group response electricity needs situations of local sites 109 and limited electric power; Have only when the electric power reduction is not enough, the scope that just progressively enlarges electric power minimizing requirement is organized to other, the electric power reduction of palpus up to reaching.

Except the group address or code that are used forlocal sites 109 each group, also can be eachlocal sites 109 and in group, distribute absolute address and code, therefore, if desired, but eachlocal sites 109 of sepaerate order.In addition; Group address or code (or frequency band or subband; And encoding scheme) one in can be system's overall situation broadcast address and code, and through indicating a plurality of orders or a series of order of system's overall situation broadcast address or code,central station 102 can arrive alllocal sites 109.

Get back to Figure 12 at present, innext procedure 1205, receive from the message ofcentral station 102 emissions at the wireless communication unit of a plurality oflocal sites 109115.In step 1208 subsequently, the information in the message that eachlocal sites 109 decoding, recovery or reconstruct are received, and if this message be what to pass to specificlocal sites 109, be each element with this message parse.If use group addressing or coding; For example; Thecontrol circuit power 112 ofspecific portion website 109 can obtain group address or coded message (for example in specific fields) from receive message; Compare thereby will receive the group address of message or the group address or the coding of coding and local sites oneself, just can confirm to receive message and whether be and pass to this specific portion website 109.Similarly, group address that receives message or coding are compared with system's overall situation broadcast address or coding,local sites 109 can confirm whether this reception message is the system's global broadcast messages that passes alllocal sites 109 in electricpower management system 100.

Suppose that message is what to pass to local sites 109, then local sites 109 is resolved these message, so that the character of the communication of confirming to receive from central station 102.As the example of the message that possibly receive, local sites 109 can receive the message indication, and it gets into the acme of next power alarms, the minimum stage that gets into next power alarms, adjustment parameter or takes some action (as showing power alarms stage alert message).Also can adopt multiple other type of message.If the control circuit power 112 of the message that receives indication local sites 102 gets into the acme of next power alarms; In step 1236; Control circuit power 112 is confirmed break off which power switch control and a plurality of switch (like the switch among Fig. 2 262), thereby partial electrical load 120 is reduced.Example how to make such decision referring to figs. 2 and 3 with the explanation in other places.In step 1238, break off power switch control or a plurality of switch of institute's palpus, in step 1250, upgrade a plurality of positioning indicators (like LEDs).For example, can light the LED that is next to the power switch control that has broken off.Also can use other state indicating device; For example, can send the sound that to hear, temporarily break off to point out one or more electrical loads 120 to the user by control circuit power 112.

On the other hand; If the message that receives indicatescontrol circuit power 112 and gets into the minimum stage of next power alarms; In step 1240 (and supposing thatcontrol circuit power 112 is not at non-warning stage) so;Control circuit power 112 confirms that which power switch control and a plurality of switch should be closed, thereby which partialelectrical load 120 is connected to power line 108.Map 2 and Fig. 3 and other places of this paper have explained how to make the example that thisconfirms.In step 1243, power switch control or a plurality of switch of closed institute palpus instep 1250, upgrade a plurality of positioning indicators (like LEDs) once more.For example, can turn-off the LED that is next to each power switch control that connects once more.

Neither indicate the highest stage of the next one that gets into power alarms if receive message, also do not indicate the next minimum stage that gets into power alarms, so instep 1225, message is bycontrol circuit power 112 parsings and abide by its operation.Concrete action depends on the character that receives message.For example; Power alarms will be sent if this message is warning;Control circuit power 112 can show that indicated message (if necessary and the time quantum before the power alarms of expection together) and/or sends the noise that can hear, indicates interested message to receive.

Ifcontrol circuit power 112 is adjusted power switch control on one's own initiative; Power consumption (for example through local meter) through monitoringlocal sites 109 is broken off and closed this switch; Can reviseprocessing procedure 1200 so to realize feedback control loop; Whereincontrol circuit power 112 continues to confirm the power switch control setting, the setting of adjustment power switch control, and update mode indicating device.In local power dynamic monitoring that consumes and the place of adjusting generation,control circuit power 112 can break off and closed power switch control arbitrary given the different of power alarms stage constantly.In such embodiment,control circuit power 112 can be through configuration so that the switching frequency of restriction power switch control, thereby minimize the inconvenience of local users.

Figure 13 explains another processing procedure that is used for electrical management 1300, and it is similar to the described processing procedure 1200 of Figure 12, but some change is arranged.In Figure 13, step 1301,1305 and 1308 generally is similar to the step 1201,1205 and 1208 among Figure 12.Equally, step 1336,1338,1340,1343 and 1350 generally is similar to the described corresponding steps of Figure 12.Yet, in Figure 13, on the described processing procedure 1200 of Figure 12, increased new step 1330,1332 and 1335.The step that is increased to the processing procedure 1300 of Figure 13 has been explained a kind of situation, and wherein getting into the next the highest power alarms stage will be by a certain amount of time of delay, and this time is stipulated by central station 102.In this situation; According to the described embodiment of Figure 13, when confirm having received the message indication, control circuit power 112 gets into the next one the highest power alarms stage, and control circuit power 112 also obtains an indication from receive message; Indicate whether to get into immediately the highest power alarms stage of the next one; Still delay gets into, if postpone to get into, indicates power alarms stage time quantum before.If enter into the highest power alarms stage of the next one immediately, processing procedure 1300 directly enters step 1336 so.If postpone to get into the highest power alarms stage of the next one, so in step 1332, control circuit power 112 gives a warning, and warning can be taked such as lighting emergency warning lamp, sending forms such as the sound that can hear or acoustic pattern.Subsequently, shown in step 1335, after delay period finishes, get into step 1336 before, the 112 latency delays cycles of control circuit power are overtime.Control circuit power 112 can use timer internal or clock to measure delay period, to realize aforesaid operations.

Figure 10 has explained a plurality of key elements relation to each other according to the local energy control system 1012 of an embodiment disclosed herein, has explained to be used for confirming that part at least confirms the potential application from the feedback of local meter 1092 of gate-controlled switch 1062 operations.Shown in figure 10, one group of on-off controller 1037 is used to control the setting of a plurality of gate-controlled switches 1062, and this gate-controlled switch is similar to referring to figs. 2 and 3 described gate-controlled switch, allows selectively to connect and break off the partial electrical load.1092 monitoring of local power meter from input power cord 1008 (or replacedly; Out-put supply line 1063) electric power that is obtained on; And output power consumption measuring-signal is provided to evaluator 1030 (it can show as the processor according to program stored is instructed and work is carried out in various input) with it.Evaluator 1030 compares power usage measured value and power usage desired value 1094, to confirm whether extra gate-controlled switch 1062 should break off or closure.Power usage desired value 1094 preferably sets according to the power alarms stage rank 1093 of local energy control system 1012.If evaluator 1030 is based on the power usage measured value; Determine local power consumption and surpass power usage desired value 1094; Evaluator 1030 is provided with 1038 definite which gate-controlled switch 1062 disconnections or closed based on priority so; As noted earlier, this priority is provided with 1038 can be through interface 1029 manual or program settings.When central station receives power command 1017, evaluator 1030 upgrades power alarms stage rank 1093 and power usage target 1094 on request.Therefore local energy control system 1012 provides the robustness control of certain level to the power consumption of local sites, and can advantageously be applied to electric power management system, as shown in Figure 1, reduces when electric industry requires, to realize total electricity needs.

Fig. 9 is the block diagram of the embodiment of localenergy control system 900, and it has explained the principle that is adopted, and a plurality of electric power management systems that for example and here disclose combine, and the mechanism that is used to provide electrical power to localenergy control system 900 has been described, and other.As shown in Figure 9, localenergy control system 900 comprisesenergy controller 910, and through it, a plurality of gate-controlledswitches 962 can be used for breaking off the electric power frominput power cord 908 to a plurality of partial loads selectively, among Fig. 9, are expressed assensing element 919 visually.Described with Fig. 3 like earlier in respect of figures 2, for example gate-controlledswitch 962 can be connected with circuit breaker 951 (or other similar electric devices) and a plurality of partial load (as inserting therebetween).Decoupling device 911 is preferably used for allowing electric power to be fed toenergy controller 910 from input power cord 908.In a preferred embodiment,decoupling device 911 comprises capacitor (possibly make up with other circuit elements), though in interchangeable embodiment,decoupling device 911 can comprise transformer, and if suitable, the support circuit element.

In alternative embodiment, can be indirectly toenergy controller 910 supply electric power, for example from the output of a circuit-breaker 951 (circuit breaker that does not preferably have gate-controlledswitch 962, thereby it can not be disconnected).

The character of the electric power signal on input power cord 908 (or more generally, thepower line 108 among Fig. 1) depends in part on user type.It is 23 to 138kV electric power that big industrial consumer's (like railway) can directly accept voltage levvl, and general further reduction voltage.Little industry or business user accept usually voltage levvl 4.16 to the electric power of 34.5kV.Consumption of resident person or light business user be general, and to accept nominal voltage level from part dispensing transformer be 120 and/or 240 volts electric power.The electric power that consumption of resident person or light business user receive is at single phase alternating current (A.C.) (AC) electricity normally in nature, and nominal frequency is about 60 hertz.Above-mentioned exemplary value is a Unite States Standard, and other local possibilities of the world are different.

Now, will describe some preferred controllable electronic switch, especially various local energy control units, wherein said controllable electronic switch are used for the continuous local sites of the disclosed a plurality of electric power management systems in place therewith.Yet what at first will introduce is the comparison between preferred controllable electronic switch and the conventional electrical components, and particularly, what at first will introduce is exactly preferred controllable electronic switch and based on the comparison between the bimetallic circuit-breaker.

Fig. 4 is the concept map based on bimetallic circuit-breaker 400 known in the field.As shown in Figure 4, circuit-breaker 400 comprisesbimetallic arm 401, and it is formed by two metal levels 402,403.Bimetallic arm 401 is fixed on anend 406, and 406 links input electricpower signal line 415 endways.At anotherend 407,bimetallic arm 401 rests on andelectric conductor 420 positioncontacting.Electric conductor 420 can be linked on the load (not shown), and in normal running (being normal current), links in the load throughbimetallic arm 401 andelectric conductor 420 from the electric power of electricpower signal line 415.

Select the metallics of the different metal layer 402,403 ofbimetallic arm 401, make it have different thermal characteristicss, so that be heated with different speed.Particularly, the rate of heat addition of the metallics ofmetal level 402 is faster than the metallics oftop metal level 403 below.When the magnitude of current that flows throughbimetallic arm 401 was in " normally " boundary, the heat that electric current flows through bimetallic arm 401 (it has intrinsic resistance) generation was little, andbimetallic arm 401 is indeformable.Yet; When the magnitude of current that flows throughbimetallic arm 401 exceeds overcurrent boundary (it is mainly determined by the relatively hot characteristic of the metallics that is used formetal level 402 and 403); Followingmetal level 402 rates of heat addition are faster than the rate of heat addition oftop metal level 403;Cause 401 bendings of bimetallic arm, thereby break off the circuit paths of 420 of input electricpower signal line 415 and electric conductors.

This operation can be by Fig. 5-1 and Fig. 5-2 explanation.Fig. 5-the 1st explains the figure of the example of the electric current when 400 closures of the circuit-breaker among Fig. 4 (normal running), Fig. 5-the 2nd, and the bimetallic arm 401 that circuit-breaker 400 is described is the figure of the example that open circuit connects when overcurrent condition occurs how.Shown in Fig. 5-1, electric power signal flows through input power cord 415 (being labeled as " IN "), flows through bimetallic arm 401 and strides across contactor 412, arrives electric conductor 420 (being labeled as " OUT ").As long as the magnitude of current in the electric power signal is below the overcurrent boundary, the heat that electric current flows through 401 generations of bimetallic arm is little, and bimetallic arm 401 is indeformable.Yet, shown in Fig. 5-2, when the magnitude of current that flows through bimetallic arm 401 surpasses the overcurrent boundary, current flow heats bimetallic arm 401, but below metal level 402 faster than top metal level 403 heating, thereby cause 401 bendings of bimetallic arm.The result is that contactor 412 separates gradually, the circuit paths disconnection between input electric power signal line 415 and the electric conductor 420.Must the magnitude of current that causes circuit-breaker 400 " tripping operation " depend on the relative thermal characteristics of double-metal layer 402,403 of bimetallic arm 401.

After tripping operation, thebimetallic arm 401 of circuit-breaker 400 will cool off gradually, up to finalbimetallic arm 401 not redeformations.Along with the generation of this phenomenon,contactor 412 forms again and is electrically connected, and allows electric power signal to pass toelectric conductor 420 frominput power cord 415.

Fig. 6 is the figure of controllableelectronic switch 600, and for example, it can be used among some embodiment of distributing electric power described herein and management system and method and local energy control unit.As shown in Figure 6, controllableelectronic switch 600 comprisesCrumple element 601, and general shape (being similar to shown in Fig. 4) formation that it can arm also can comprise two layers 602,603 with different thermal characteristicss.Though can use the durable materials of any heated bending, in fact two layers 602,603 are preferably metal.As among Fig. 6 further shown in,Crumple element 601end 606 preferred immobilization arrive non-conductive surperficial 615.At another end,Crumple element 601 preferably rests on the position that is connected withelectric conductor 620 through contactor 612.Input power cord 625 preferably links to each other withCrumple element 601 near the contact point ofelectric conductor 620; So that minimize the power consumption that causes by electric current throughCrumple element 601; Also avoidheating Crumple element 601 to any significant degree, no matter obtain great electric current.Electric conductor 620 can be connected to the load (not shown); In normal running (as following the explanation; Just be not activated switch controlling signal), be conducting to load from the electric power of power controllingsignal line 625 throughCrumple element 601 andelectric conductor 620.

The metallics of the different metal layer 602,603 ofCrumple element 601 preferably has different thermal characteristicss, so that they are with different speed heating.Particularly, the metallics of preferred followingmetal level 602 is faster than the rate of heat addition of the metallics of top metal level 603.When heat is applied to 601 last times of Crumple element; Compare withtop metal level 603, belowmetal level 602 heating faster, causeCrumple element 601 bendings; Be similar to circuit-breaker 400, thereby break off the circuit paths between input electricpower signal line 625 and electric conductor.

Further said as among Fig. 6, heating element 645 (like resistive coil) is coupled to (for example under the situation of resistive coil, around above that) Crumple element 601.Heating element 645 is preferred through ON-OFF control circuit 640 controls, and ON-OFF control circuit 640 is linked on it through a pair of holding wire 641,642.When the switch controlling signal output from ON-OFF control circuit 640 is not activated;Heating element 645 breaks off (so right and wrong activity) effectively; Electric power throughinput power cord 625, stride across theend 607 ofCrumple element 601 and be transported toelectric conductor 620 throughcontactor 612, further be assigned to load at this.This operating instruction is in Fig. 7-1.Yet, when the switch controlling signal from ON-OFF control circuit 640 is activated,heating element 645 heating, this is owing to flow through the effect of the electric current of heating element 645.603 heating are faster because followingmetal level 602 adds above the ratio of specific heat metal level, andCrumple element 601 beginnings are crooked.Finally, as the result of bending,contactor 612 separates gradually, breaks off the circuit paths between input electricpower signal line 625 andelectric conductor 620, and is of Fig. 7-2.

As long as the switch controlling signal from ON-OFF control circuit 640 is activated,heating element 645 continues to keepCrumple element 601 bendings, and the circuit paths betweeninput power cord 625 andelectric conductor 620 breaks off.In case the switch controlling signal from ON-OFF control circuit 640 is not activated,Crumple element 601 is cooling gradually just, finally up to not redeformation of Crumple element.Along with the generation of this phenomenon,contactor 612 forms again and is electrically connected, and allows electric power signal to pass toelectric conductor 620 then to load from getting intocircuitry lines 625.

On the one hand, that the controllableelectronic switch 600 shown in Fig. 6 can be provided convenience, cheap mechanism is used to control the distributing electric power from the power supply to the load.And whenCrumple element 601 during in make position, controllableelectronic switch 600 needn't consume any electric power, and only requires that minimum electric power breaks off to cause Crumple element.

Input power cord 625 can be connected toCrumple element 601 in many ways.For example,input power cord 625 melting welding simply links or is welded to the activedistal end 607 of Crumple element 601.As long as whenCrumple element 601 is in switch closed position, electrically conducting betweeninput power cord 625 and theelectric conductor 620,input power cord 625 is all satisfied the demand to any type of fixing ofCrumple element 601.

Fig. 8 is the block diagram that the embodiment of more general controllableelectronic switch 800 is described.As shown in Figure 8, controllableelectronic switch 800 comprisesCrumple element 801, and it controllably connectsinput power cord 825 to electric conductor 820.Heating element 845 is coupled on theCrumple element 801, and by ON-OFF control circuit 840controls.Crumple element 801 can adopt any form; Like bimetallic element or arm; WhenCrumple element 801 is notheated element 845 heating; It preferably allowsinput power cord 825 conducting electric power signal toelectric conductors 820, but causes that preferably inputpower cord 825 being connected whenCrumple element 801 isheated element 845 heating betweenelectric conductor 820 physically break off.Heating element 845 can comprise that like resistive coil or other resistors, if resistive coil, whenCrumple element 801 showed as bimetallic element or arm, it can be wound on theCrumple element 801 easily.

Among each embodiment in Fig. 6 and Fig. 8; It is evenly straight that Crumple element 601 or 801 needs not to be; In fact, can be Any shape, as long as when heating its crooked in a predetermined manner so that break off input power cord 625 or 825 and electric conductor 620 or 820 between be electrically connected.And though Crumple element 601 or 801 is in a preferred embodiment as having the formal specification of the bimetallic arm of two metal levels, it can use any other instead can expect that the crooked material of mode (metal or other) processes.Because need not electric current flow to the other end (being different from circuit-breaker) from an end of Crumple element 601 or 801, if desired, Crumple element 601 or 801 can be separated from each other with the zones of different of part non-conductive or insulation with Crumple element 601 or 801.For example, non-conductive part (like plastics) can be positioned between the end (end 606 and/or 607 of the Crumple element 601 in Fig. 6 example) of zone and Crumple element 601 or 801 of the Crumple element 601 that is coupled to heating element 645 or 845 or 801.Further, an end of Crumple element 601 (like the end among Fig. 6 607) needs not to be bimetallic, but can be the consistent material that conducts electricity (like monometallic), is switched on through this end electric power.Replacedly, Crumple element 601 or 801 can have extra layer (promptly surpassing two-layer).Crumple element 601 or 801 main feature are its crooked fully or distortion heated the time, so that break off being electrically connected of electric power signal path (as through the contactor 612 among Fig. 6 separately).

Export preferably direct current (DC) signal from ON-OFF control circuit 640 or 840 to the switch controlling signal ofheating element 645 or 845, but also can be to exchange (AC) signal or mixed signal.When switch controlling signal is not activated; ON-OFF control circuit 640 is shortcircuit heating element 645 or 845 (as through the lead among short circuit Fig. 6 641,642) simply, otherwise just isolatesheating element 645 or 845 simply through buffer or other buffer circuits.

Though theheating element 645 and 845 among Fig. 6 and Fig. 8 has been described as resistive coil in a preferred embodiment,heating element 645 or 845 can adopt other forms or configuration.For example, if be presented as resistive coil,heating element 645 or 845 needn't twineCrumple element 601 or 801.Heating element 645 or 845 can be the dissimilar resistor except that resistive coil.Yet, resistive coil is preferablyheating element 645 or 845, be because it provides relative uniform heating on whole given zone, and be easy to realization and relatively cheap relatively.

TheCrumple element 601 or the 801 pairs of ON-OFF control circuits 640 or 840 the speed of response can be crucial, can not be crucial also, depend on certain embodiments.If the speed of response is not very crucial, switch controlling signal can be very low electric power signal so.Response time faster if desired can increase the electric power of switch controlling signal so, therefore causes thatheating element 645 or 845 heats faster.ON-OFF control circuit 640 or 840 can have its oneself power supply (like battery), otherwise its can frominput power cord 625 825 or other obtainable power supplys obtain electric power.ON-OFF control circuit 640 or 840 can be by the excitation of hand switch (not shown), and it causes the startup of switch controlling signal, and therefore final disconnection controllableelectronic switch 600 or 800, otherwise can be by the electronic remote signal excitation.

Figure 14 is another embodiment of controllable electronic switch 1400, and it uses physically being electrically connected in the open circuit of wedge-shaped element.Shown in figure 14, controllable electronic switch 1400 generally comprises the Crumple element 1401 of prolongation, and it forms by two-layer 1402,1403, is similar to the illustratedCrumple element 601 of earlier in respect of figures 6 in essence.In a preferred embodiment, Crumple element 1401 comprises the bimetallic arm, and two layers 1402; 1403 is metal in itself, though more general, two layers 1402; 1403 can be made up of suitable material, and this suitable material has enough different thermal characteristicss to carry out aforesaid function.Crumple element 1401 end 1406 preferred immobilization to non-conductive surperficial 1415 on.At its another end, Crumple element 1401 has wedge-shaped element 1451.

As Figure 14 further described, the narrow end of wedge-shaped element 1451 is in close proximity to a pair of electrical contact 1452.This is positioned at and a pair of electric conductor 1420,1425 position contacting electrical contact 1452, and first electric conductor 1425 is as input power cord, and second electric conductor 1420 is as transmitting electric power to the device of load (not shown).In normal running, from the electric power of electric conductor 1425 through electrical contact 1452 and 1420 conductings of second electric conductor, thereby with the load conducting.Electrical contact 1452 is fixed on a pair of non-conductive arm 1457, and it is fixed on the fixed surface 1460.A pair of spring 1455 or such device apply force on the non-conductive arm 1457, thereby keep the connection status of electrical contact 1452 in normal running.

The electrical path of striding electrical contact 1452 formation can break off through applying to control signal on the Crumple element 1401.For reaching this purpose, heating element 1445 (like resistive coil) be coupled to Crumple element 1401 (as be wrapped in Crumple element 1401 around, it shows as resistive coil).Preferably by ON-OFF control circuit 1440 controls, this ON-OFF control circuit 1440 is connected on it through a pair of holding wire 1441,1442 heating element 1445.When the switch controlling signal output from ON-OFF control circuit 1440 is not activated; The disconnection effectively of heating element 1445 quilts (so the right and wrong activity); Electric power through input power cord 1425, stride across electrical contact 1452, be transported to electric conductor 1420, electric power can further be assigned to load from here.Yet when the switch controlling signal from ON-OFF control circuit 1440 was activated, heating element 1445 was owing to the effect that electric current flows through heating element 1445 is heated.Be similar to earlier in respect of figures 6 described Crumple elements 601, Crumple element 1401 beginnings of controllable electronic switch 1400 are crooked.Finally; As the result of bending,, cause that contactor 1452 separates (spring 1455 gradually reduces) gradually if wedge-shaped element 1451 applies power between electrical contact 1452; And break off the circuit paths between input electric power signal line 1425 and electric conductor 1420, shown in figure 15.

As long as the switch controlling signal from ON-OFF control circuit 1440 is activated, heating element 1445 continues to keep Crumple element 1401 bendings, and the circuit paths between input power cord 1425 and the electric conductor 1420 breaks off.In case the switch controlling signal from ON-OFF control circuit 1440 is not activated, deformation element 1401 cools off gradually, finally up to Crumple element 1401 not redeformations.Along with this phenomenon takes place, wedge-shaped element 1451 withdraw gradually, causes that electrical contact 1452 is incorporated into together and form once more to be electrically connected, and its permission electric power signal passes to electric conductor 1420 from input power cord 1425 then, arrives load then.

In one aspect, similar with controllableelectronic switch 600 shown in Figure 6, that controllable electronic switch 1400 shown in Figure 14 can be provided convenience, cheap mechanism is used to control the distributing electric power from the source to the load.And controllable electronic switch 1400 need not consume any electric power when electrical contact 1452 is in the close position, and only needs minimum electric power to cause that Crumple element 1401 bendings and electrical contact opened in 1452 minutes, breaks off the electric power signal circuit paths.

Figure 16 is another enforcement illustration of controllableelectronic switch 1600, and this controllableelectronic switch 1600 uses being electrically connected in wedge-shaped element open circuit paths.Many elements shown in Figure 16 are similar to these elements shown in Figure 14 in itself.Therefore, for example, the controllableelectronic switch 1600 among Figure 16 generally comprises theCrumple element 1601 of prolongation, and it forms by two-layer 1602,1603, is similar to earlier in respect of figures 6 and the describedCrumple element 601,1401 of Figure 14 in itself respectively.In a preferred embodiment;Crumple element 1601 comprises the bimetallic arm; Though and these twolayers 1602,1603 be in itself metal more generally, this two-layer 1602,1603 can be had enough the suitable material of different thermal characteristicss and formed by any, so that carry out function describedherein.Crumple element 1601end 1606 preferred immobilization tonon-conductive surperficial 1615 on.At its another end,Crumple element 1601 has wedge-shapedelement 1651, and it is as mechanical cam, like following detailed description.

As Figure 16 further described, an end of wedge-shapedelement 1651 is in close proximity to a pair ofelectrical contact 1652 places.This is positioned at and a pair ofelectric conductor 1620,1625 position contactingelectrical contact 1652, and firstelectric conductor 1625 is as input power cord, and secondelectric conductor 1620 is as transmitting electric power to the device of load (not shown).In normal running, from the electric power ofelectric conductor 1625 throughelectrical contact 1652 and 1620 conductings of second electric conductor, thereby with the load conducting.Electrical contact 1652 is fixed on a pair ofnon-conductive arm 1657, and it is fixed on the fixed surface 1660.A pair ofspring 1655 or such device apply force on thenon-conductive arm 1657, thereby keep the connection status ofelectrical contact 1652 in normal running.

Be similar to the embodiment of Figure 14, the electrical path of striding electrical contact 1652 breaks off through application controls signal to Crumple element 1601.In order to reach this purpose, heating element 1645 (like resistive coil) be coupled to Crumple element 1601 (as be wrapped in Crumple element 1601 around, it shows as resistive coil).Preferably by ON-OFF control circuit 1640 controls, this ON-OFF control circuit 1640 is connected on it through a pair of holding wire 1641,1642 heating element 1645.When the switch controlling signal output from ON-OFF control circuit 1640 is not activated; The disconnection effectively of heating element 1645 quilts (so the right and wrong activity); And electric power through input power cord 1625, stride across electrical contact 1652, be transported to electric conductor 1620, electric power can further be assigned to load from here.Yet when the switch controlling signal from ON-OFF control circuit 1640 was activated, heating element 1645 was owing to the effect that electric current flows through heating element 1645 is heated, and as a result of, Crumple element 1601 beginnings are crooked.Finally; As the result of bending,, cause that connecting 1652 separates (spring 1655 gradually reduces) gradually if wedge-shaped element 1651 applies power between electrical contact 1652; And break off the circuit paths between input electric power signal line 1625 and electric conductor 1620, be similar to shown in Figure 15.

Be different from the embodiment among Figure 14, the wedge-shaped element 1651 of the controllable electronic switch 1600 among Figure 16 is as mechanical cam, and it has a plurality of latched position, therefore alleviates the needs that the retentive control signal breaks off with holding circuit.Fashionable in first positional lock when wedge-shaped element 1651, it is removed from electrical contact 1652, and this contactor remains closed, and the electric power signal circuit paths does not interrupt.On the other hand, when wedge-shaped element 1651 was locked together in the second place, it ordered about electrical contact and opened in 1652 minutes, so interrupt power signal circuit path.In each latched position, do not need electric power to keep controllable electronic switch 1600 its current state (breaking off or closure).In this example, wedge-shaped element 1651 realizes through latch members 1680 that in the sealed of a plurality of positions for example, wherein latch members is included in the arm 1682 that stops in the spheroid 1681, and this spheroid and wedge-shaped element 1651 offset.In this example, the arm 1682 of latch members 1680 is fixed on the surface 1660, but latch members 1680 can be fixed on any other available surface.Therefore, in this example, latch members 1680 closes on arm 1657, and this arm 1657 supports electrical contact 1652.

Figure 17-1,17-2 and 17-3 are the example different views of the wedge-shapedelement 1651 of the controllableelectronic switch 1600 among explanation Figure 16, and particularly, Figure 17-2 is sealed in primary importance with the wedge-shapedelement 1651 among the 17-3 key diagram 17-1.Wedge-shapedelement 1651 in this example comprises front wedge part 1705 (it typically is wide surface, tilt),central recess 1701 and back side wedge part 1706 (its can be taper, tilt), backside wedge part 1706 has been confirmed shallow rearward recess 1708.Explain best that like Figure 17-2 and 17-3 when wedge-shapedelement 1651 was locked together in primary importance, thespheroid 1681 oflatch members 1680 was positioned on thefront wedge part 1705 and (in order more to clearly illustrate other characteristics, has omittedarm 1682 among Figure 17-2 and the 17-3).When it was locked together in primary importance,spheroid 1681 can keep wedge-shapedelement 1651 in position effectively, though in certain embodiments,spheroid 1681 needn't contact with wedge-shapedelement 1651, and near general position it.

Figure 18-1 is the figure how explanation wedge-shaped element 1651 is changed between different latched position to 18-8.Figure 18-2 and 18-3 are similar to Figure 17-2 and 17-3 respectively, are presented at the static wedge-shaped element 1651 of first latched position.Figure 18-3 explanation is applied to the control signal of heating element 1645 along with Crumple element 1601 responses and the situation (shown in figure 16) that taken place when being heated.In this situation, Crumple element 1601 beginnings are crooked, order about wedge-shaped element 1651 and advance.When this took place, spheroid 1681 slippage on the inclined surface of front wedge part 1705 in the central recess that is still in wedge-shaped element 1,651 1701, made wedge-shaped element be stabilized in second latched position.For purpose relatively, first latched position is to be represented by the strokes and dots outline line 1651 ' of wedge-shaped element, though actual mobile size is because of illustrative purposes and by exaggerative.In fact, a few percent inch that only moves of wedge-shaped element 1651 just enough changes latched position.Even after control signal is not activated, spheroid 1681 still keeps wedge-shaped element 1651 in second latched position, and this is because it firmly is still in the central recess 1701.Can keep in touch device when therefore, wedge-shaped element 1651 remains on second latched position opened in 1652 minutes.

The application of control signal subsequently causes that wedge-shaped element 1651 turns back to first latched position.When the control signal that applies subsequently, Crumple element 1601 is heated once more, causes its bending, and wedge-shaped element 1651 moves forward.Therefore spheroid 1681 is displaced central recess 1701, is driven on the second wedge part 1706, shown in Figure 18-5.Spheroid 1681 is in the conical surface slide down of the second wedge part 1706; And because the very narrow end (being preferably asymmetrical taper) of the second wedge part 1706; Spheroid 1681 slips on the side of the more taper of the second wedge part 1706; And the upper lip by shallow rearward recess 1708 is captured, shown in Figure 18-6.The upper lip of shallow rearward recess 1708 helps the outer surface 1710 guiding spheroids 1681 along wedge-shaped element 1651; Shown in top view among end view and Figure 18 among Figure 18-7-8; In this process, the arm 1682 of latch members 1680 orders about (or vice versa) to the side of wedge-shaped element 1651.Along with Crumple element 1601 coolings; Spheroid 1681 is along outer surface 1710 slippages of wedge-shaped element 1651; And finally arrive the narrow tip region of front wedge part 1705; Wherein the arm 1682 of latch members 1680 is directly stretched and spheroid 1681 is driven on the surface of front wedge part 1705, and wedge-shaped element 1651 returns first latched position, shown in Figure 18-1 and 18-2.

Above process can repeat on demand, with through letting wedge-shapedelement 1651 between first and second latched position, move, and allow controllableelectronic switch 1680 to break off and close contactors 1652.The control signal that applies in order to cause wedge-shapedelement 1651 to move can adopt the form like pulse signal.

Figure 19 is the view of another embodiment of controllableelectronic switch 1900, and it uses being electrically connected in the wedge-shaped element open circuit path, also adopts the principle of the mechanical cam with a plurality of latched position.In Figure 19, controllableelectronic switch 1900 generally comprises theCrumple element 1901 of prolongation, and it forms by two-layer 1902,1903 as the front, is similar to earlier in respect of figures 6 and 14 describedCrumple elements 601,1401 in essence respectively.In a preferred embodiment;Crumple element 1901 comprises the bimetallic arm, and twolayers 1902,1903 are metal in itself, though more generally; These twolayers 1902,1903 can be made up of any material with enough different thermal characteristicss, to carry out the function of explanation here.Crumple element 1901 arrives non-conductive surperficial 1960 a terminal preferred immobilization.At its another end,Crumple element 1901 has wedge-shapedelement 1951, and it is used as mechanical cam, will explain in more detail as following.

Explain further that like Figure 19swing arm 1980 is positioned between first wedge-shapedelement 1951 and a pair of electrical contact 1952.This is positioned at and a pair ofelectric conductor 1920,1925 position contactingelectrical contact 1952, and firstelectric conductor 1925 is as input power cord, and secondelectric conductor 1920 is as the device of the load (not shown) that transmits electric power.In normal running, from the electric power of firstelectric conductor 1925 throughelectrical contact 1952 and 1920 conductings of second electric conductor, thereby with the load conducting.Electrical contact 1952 is fixed on a pair ofnon-conductive arm 1957, and it is fixed on (not shown) on the fixed surface.A pair of spring (not shown, but be similar to thespring 1655 among Figure 16) or other such devices apply force on thenon-conductive arm 1957, and therefore keep the link position ofelectrical contact 1952 in normal running.

Like that kind of Figure 19 shown in further,swing arm 1980 has spheroid 1981 at an end, at the relative other end second wedge-shapedelement 1961 is arranged.Can run-on point 1984 places ofswing arm 1980 in the position that centers usually be fixed on the fixedstructure 1985.
