具有控制和保护功能的开关电器Switching appliances with control and protection functions

技术领域technical field

本发明涉及一种具有控制和保护功能的开关电器，特别是用于电动机控制和保护的具有接触器和断路器功能的开关电器。The invention relates to a switching device with control and protection functions, especially a switching device with the functions of a contactor and a circuit breaker for motor control and protection.

背景技术Background technique

断路器一般用于配电线路，接触器一般用于控制系统。接触器具有频繁操作的能力和较长的寿命，但不具有过载、短路保护功能以及较高的开断性能，而断路器具有较好的过载、短路保护功能和较高的开断性能，但不能频繁操作及寿命相对较短。但是有相当一些用电设备不仅要求能够实现频繁操作而且要求能够实现过载和短路保护。而具有控制和保护功能的开关电器，其控制功能利用接触器的电磁铁部件实现，通过人为断开或接通电磁铁部件的电源，就能实现断开和接通带有电机等负载的主电路；其保护功能利用断路器的脱扣器部件实现，当脱扣器监测到至少一根线路上存在如过载、短路等电气故障时，立即促使操作机构动作，从而断开主电路。Circuit breakers are generally used in distribution lines, and contactors are generally used in control systems. The contactor has the ability to operate frequently and has a long life, but it does not have overload and short-circuit protection functions and high breaking performance, while the circuit breaker has good overload and short-circuit protection functions and high breaking performance, but It cannot be operated frequently and has a relatively short lifespan. However, there are quite a few electrical equipment that require not only frequent operation but also overload and short-circuit protection. For switching appliances with control and protection functions, the control function is realized by the electromagnet part of the contactor. By artificially disconnecting or connecting the power supply of the electromagnet part, it can realize disconnection and connection of the main load with the motor and other loads. Circuit; its protection function is realized by the release part of the circuit breaker. When the release detects electrical faults such as overload and short circuit on at least one line, it immediately prompts the operating mechanism to act, thereby disconnecting the main circuit.

传统的具有控制和保护功能的开关电器的作法是同时使用分立器件保护一个用电设备，即同时使用断路器、接触器、电动机保护器或热继电器、起动器等，这样为了保护一个用电设备，同时要多个开关电器配合使用，并且还要使用大量的机械连接和电气连接，既浪费资源又浪费空间，接线及安装烦琐，并且要考虑多个开关电器的配合使用问题。The traditional method of switching electrical appliances with control and protection functions is to use discrete devices to protect an electrical equipment at the same time, that is, to use circuit breakers, contactors, motor protectors or thermal relays, starters, etc. at the same time, so that in order to protect an electrical equipment , At the same time, multiple switching devices must be used together, and a large number of mechanical connections and electrical connections must be used, which wastes resources and space, wiring and installation are cumbersome, and the use of multiple switching devices must be considered.

现有的一种具有接触器和断路器功能的开关电器，其脱扣保护器采用机械式，此类开关电器的缺点是需要大量的开关，否则不能满足所需范围的电源电压和电源电流的要求。An existing switching device with the functions of a contactor and a circuit breaker uses a mechanical trip protector. The disadvantage of this type of switching device is that it requires a large number of switches, otherwise it cannot meet the required range of power supply voltage and power supply current. Require.

现有的另一种具有接触器和断路器功能的开关电器，其电磁铁在接触器模式和断路器模式下对触头进行开关控制，这种电磁铁混合用作接触器模式和断路器模式的工作特点，不能满足在断路器模式下需要快速分断的要求。Another existing switching device with the functions of a contactor and a circuit breaker, its electromagnet performs switching control on the contacts in the contactor mode and the circuit breaker mode, and this electromagnet is used in both contactor mode and circuit breaker mode The working characteristics of the circuit breaker cannot meet the requirements of fast breaking in the circuit breaker mode.

ZL00813988.1的发明专利公开了现有的又一种具有接触器和断路器功能的开关电器，该专利采用了电磁铁、电磁跳闸装置、保护装置和控制机构，其中电磁跳闸装置与控制机构一起使用，保护装置通过控制线连接到电磁铁上，并通过跳闸线路连接到控制机构上。该已有技术的主要前提条件是：电磁铁为在预定电压下工作的DC型电磁铁，不管电源电压为AC型或DC型，均需要先通过适配电路将电源电压转变为预定电压以向电磁铁供电。这种必需增加电压转换、适配和稳压电路的直流磁系统，不仅结构复杂、成本高，且因增加转换电路会导致产品的可靠性下降。再有，该已有技术的短路保护倍数不能按用户要求在现场设定，可能会造成短路倍数太大而不能有效保护用电设备，不能充分满足用户的使用要求，造成产品的安全保护性能下降。此外，脱扣器的品种繁多，由于这种电器的脱扣等级和用电设备的电极类型不能设定，会使用户在采购过程中增加出错率，管理、运输、储备不方便、不经济。还有，这种电器的电磁铁、电磁跳闸装置需分别通过控制机构及其滑动或枢转装置作用在动触头上，很显然，这种多个控制机构和滑动或枢转装置分别作用于动触头的结构十分复杂，不仅制造成本很高，而且还限制了如辅助触头组等参与对动、静触头闭合/断开状态的控制或监测的附件的接入数量，从而大大降低了产品的使用性能，显著增加了产品的生产成本。The invention patent of ZL00813988.1 discloses another existing switching device with the function of contactor and circuit breaker. The patent uses electromagnet, electromagnetic tripping device, protection device and control mechanism, wherein the electromagnetic tripping device and the control mechanism In use, the protection device is connected to the electromagnet through the control line and connected to the control mechanism through the trip line. The main premise of this prior art is: the electromagnet is a DC type electromagnet working at a predetermined voltage, no matter the power supply voltage is AC type or DC type, it is necessary to first convert the power supply voltage to a predetermined voltage through an adaptation circuit to The electromagnet is powered. This kind of DC magnetic system, which must add voltage conversion, adaptation and voltage stabilization circuits, not only has a complex structure and high cost, but also reduces the reliability of the product due to the addition of conversion circuits. Furthermore, the short-circuit protection multiple of this prior art cannot be set on site according to user requirements, which may cause the short-circuit multiple to be too large to effectively protect electrical equipment, and cannot fully meet the user's requirements for use, resulting in a decline in the safety protection performance of the product . In addition, there are many types of trippers. Since the tripping level of this electrical appliance and the electrode type of the electrical equipment cannot be set, the user will increase the error rate in the procurement process, and the management, transportation, and storage are inconvenient and uneconomical. In addition, the electromagnet and the electromagnetic tripping device of this electrical appliance need to act on the moving contact through the control mechanism and its sliding or pivoting device respectively. Obviously, these multiple control mechanisms and sliding or pivoting devices act on the The structure of the moving contact is very complicated, not only the manufacturing cost is high, but also the number of accessories that participate in the control or monitoring of the closing/opening state of the moving and static contacts, such as the auxiliary contact group, is limited, thereby greatly reducing The use performance of the product is significantly increased, and the production cost of the product is significantly increased.

下面根据具有控制和保护功能的开关电器的两个用途特点，与现有技术对比说明本发明的有益技术效果。The beneficial technical effect of the present invention will be described below in comparison with the prior art according to the two application characteristics of the switching device with control and protection functions.

所述开关电器的用途特点之一，是它连接于某种用电设备与电源之间，由于各种用电设备的电压类型、电极极数、额定电流、短路保护倍数和脱扣等级等要求不同，所以开关电器的适配性能是其十分重要的性能指标。所述的适配性能，是指同一型号的开关设备能适配多种用电设备和能满足多种电压类型、电极极数、额定电流、短路保护整定倍数、脱扣等级的要求的性能。现有技术如ZL00813988.1专利采用保护模块可互换以解决额定电流的适配问题，但未解决电压类型、短路保护和脱扣等级的适配问题，而且额定电流的适配仅是采用保护模块的互换的方法，而不能由用户在现场自行设定。很显然，这种已有电器的适配性很差，一是需要按额定电流不同配置多种型号的保护模块附件，二是由于保护模块附件的品种有限，使用户可选择的范围受到限制。本发明的脱扣器不仅可根据用电设备的电压类型和额定电流选取配置，而且还可以由用户在现场设定过载/短路保护整定倍数、脱扣等级和负载电极极数。因此，本发明的技术方案，不仅可最大限度的减少可互换脱扣器的品种型号，而且还可为用户提供极为广泛的短路保护和脱扣等级的选择范围。One of the characteristics of the use of the switching device is that it is connected between a certain electrical equipment and the power supply. Different, so the adaptation performance of the switching device is a very important performance index. The adaptability mentioned above refers to the performance that the switchgear of the same type can adapt to various electrical equipment and meet the requirements of various voltage types, number of poles, rated current, short-circuit protection setting multiple, and tripping level. Existing technology such as ZL00813988.1 patent uses interchangeable protection modules to solve the problem of adapting the rated current, but it does not solve the problem of adapting the voltage type, short-circuit protection and trip level, and the adaptation of the rated current is only the use of protection The exchange method of the modules cannot be set by the user on site. Obviously, the adaptability of this existing electrical appliance is very poor. First, it is necessary to configure various types of protection module accessories according to the rated current. Second, due to the limited variety of protection module accessories, the range of choices for users is limited. The tripper of the present invention can not only be selected and configured according to the voltage type and rated current of the electrical equipment, but also can be set by the user on site to set the overload/short circuit protection setting multiple, trip level and load pole number. Therefore, the technical solution of the present invention can not only reduce the varieties and models of the interchangeable trippers to the greatest extent, but also provide users with a very wide selection range of short-circuit protection and tripping levels.

具有控制和保护功能的开关电器的用途特点之二，是需要有选择地可互换地配置多种控制和监测辅件，其中最为重要的也是使用最为普遍的辅件如辅助触头、通信模块或功能模块。因此，具有控制和保护功能的开关电器本体能否兼容和是否设有供多种类型和型号的控制和监测辅件接入的接口，是其另一项重要的性能指标。现有技术如ZL00813988.1专利，虽然也设有供接入辅助触头附件和通信附件的接口和空间，但由于其辅助触头附件和通信附件均需通过保护模块才能对动触头实现连接，所以该已有技术方案的另一缺陷是，可互换式保护模块十分复杂、价格昂贵、更换困难，而且还限制了可接入的附件的数量，这些缺陷都会大大影响产品的使用功能和性能。而本发明的技术方案，可实现辅助触头附件直接与动触头发生连接，不仅使得脱扣器十分简单，而且可将辅助触头附件的可接入数扩大至2个以上，脱扣器、辅助触头附件、通信模块或功能模块的更换十分方便。The second characteristic of switching electrical appliances with control and protection functions is that it is necessary to selectively and interchangeably configure a variety of control and monitoring accessories, the most important of which are also the most commonly used accessories such as auxiliary contacts, communication modules, etc. or function modules. Therefore, whether the switchgear body with control and protection functions is compatible and whether it is provided with interfaces for various types and types of control and monitoring accessories is another important performance index. Existing technology such as ZL00813988.1 patent, although there are also interfaces and spaces for accessing auxiliary contact accessories and communication accessories, but because the auxiliary contact accessories and communication accessories need to pass through the protection module to realize the connection to the moving contact , so another defect of this prior art solution is that the interchangeable protection module is very complicated, expensive, difficult to replace, and also limits the number of accessories that can be connected. These defects will greatly affect the function and function of the product. performance. However, the technical solution of the present invention can realize the direct connection between the auxiliary contact accessories and the moving contacts, which not only makes the tripper very simple, but also expands the number of auxiliary contact accessories that can be connected to more than two, and the tripper , Auxiliary contact accessories, communication modules or functional modules can be easily replaced.

Thebase 95 is equipped with astatic contact 93 and a movingcontact 92 . Thestatic contact 93 is connected to the maincircuit power terminal 106 and the maincircuit load terminal 105 provided on the base 95 through thepower conductors 16 and 17 respectively. Themovable contacts 92 are arranged at both ends of thecontact bridge 19 , one side of thecontact bridge 19 is fixedly connected to thecontact support 11 and one side is adjacent to the contact support positioning surface, and the other side is connected to one end of thespring 15 . The other end of thespring 15 is fixed on thebase 95 and provides driving force and contact force for the movingcontact 92 to close to thestatic contact 93 . Thecontact support 11 is controlled by thetransmission device 20. In the closed state, thetransmission device 20 does not contact thecontact support 11, so that the movingcontact 92 contacts the static contact under the elastic force of thespring 15. 93 contact closure, and form a stable contact force between the dynamic and static contacts; in the process of tripping or opening, thetransmission device 20 is always in contact with thecontact support 11, and drives the movingcontact 92 to overcome the elastic force of thespring 15 to act The movement of separating from thestatic contact 93, so that the dynamic and static contacts are disconnected.

Here, only one of the communication module and the function module can be selected, both of which are represented byreference numeral 112 .

设置在罩壳99上的控制电源端子108直接通过电源导线101a和101b，并联连接在电磁铁40和电压变换电路80的输入端上，并通过电压变换电路80将控制电源电压转换为预定直流电压输出。控制电源端子108的电压可以是交流型，也可以是直流型。所述电压变换电路80的输出端分别通过连接导线102和103与磁通适配器52和处理电路53并联连接，分别为它们提供工作电压。在控制电源端子108与电磁铁40、磁通适配器52和电压变换电路80的供电线路中，还串联一个受操作机构60控制的开关48。只有当操作机构60合闸时，开关48才能接通，电源才可以向电磁铁40、磁通适配器52和处理电路53供电。电压变换电路80由桥式整流电路、降压或升压变换电路、稳压变换电路中的一种或几种构成，能够把控制电源端子108的电源电压(如AC24V、AC48V、AC72V、AC110V、AC127V、AC220V、AC230V、AC240V、DC24V、DC48V、DC72V、DC110V、DC125V、DC220V、DC250V)转换为预定直流电压，作为磁通适配器52、处理电路53的工作电压。The controlpower supply terminal 108 provided on thecasing 99 is directly connected in parallel to the input end of theelectromagnet 40 and thevoltage conversion circuit 80 through thepower supply wires 101a and 101b, and the control power supply voltage is converted into a predetermined DC voltage by thevoltage conversion circuit 80 output. The voltage of the controlpower supply terminal 108 can be AC or DC. The output terminals of thevoltage conversion circuit 80 are respectively connected in parallel with themagnetic flux adapter 52 and theprocessing circuit 53 through connectingwires 102 and 103 to provide them with operating voltages respectively. In the power supply line between the controlpower supply terminal 108 and theelectromagnet 40 , themagnetic flux adapter 52 and thevoltage conversion circuit 80 , aswitch 48 controlled by theoperating mechanism 60 is connected in series. Only when theoperating mechanism 60 is closed, theswitch 48 can be turned on, and the power supply can supply power to theelectromagnet 40, themagnetic flux adapter 52 and theprocessing circuit 53. Thevoltage conversion circuit 80 is composed of one or more of a bridge rectifier circuit, a step-down or boost conversion circuit, and a voltage-stabilizing conversion circuit, and can control the power supply voltage of the power supply terminal 108 (such as AC24V, AC48V, AC72V, AC110V, AC127V, AC220V, AC230V, AC240V, DC24V, DC48V, DC72V, DC110V, DC125V, DC220V, DC250V) is converted into a predetermined DC voltage as the working voltage of themagnetic flux adapter 52 and theprocessing circuit 53.

脱扣器50包括电流互感器55和处理电路53。电流互感器55能够在主电路发生如过载、短路等电气故障时，监测到过载/短路电流信号，处理电路53再对过载/短路电流信号进行分析处理后，向磁通适配器52输出跳闸指令，从而磁通适配器52驱动操作机构60跳闸，使动触头92从闭合位置转换到断开位置。Thetrip unit 50 includes acurrent transformer 55 and aprocessing circuit 53 . Thecurrent transformer 55 can monitor the overload/short circuit current signal when electrical faults such as overload and short circuit occur in the main circuit, and theprocessing circuit 53 outputs a trip command to themagnetic flux adapter 52 after analyzing and processing the overload/short circuit current signal. Thus, themagnetic flux adapter 52 drives theoperating mechanism 60 to trip, so that themovable contact 92 switches from the closed position to the open position.

本发明的一个重要发展在于，电磁铁40直接由控制电源端子108供电，供电的通/断受开关48控制，电压类型为交流型或直流型，由客户根据所需电源电压选取。操作机构60位于电磁铁40的上方或侧面，它不仅受人为控制和脱扣器50的磁通适配器52的控制，而且还可以控制开关48。本发明的具有控制和保护功能的开关电器不工作时或者控制电源端子108的电压为0时，操作机构60和电磁铁40都压住传动装置20，使开关48断开，保持动触头92处于断开位置。An important development of the present invention is that theelectromagnet 40 is directly powered by the controlpower supply terminal 108, the on/off of the power supply is controlled by theswitch 48, and the voltage type is AC or DC, which is selected by the customer according to the required power supply voltage. Theoperating mechanism 60 is located above or on the side of theelectromagnet 40 , it is not only controlled by the human control and themagnetic flux adapter 52 of thetrip unit 50 , but also can control theswitch 48 . When the switching device with control and protection functions of the present invention is not working or when the voltage of the controlpower supply terminal 108 is 0, theoperating mechanism 60 and theelectromagnet 40 all press thetransmission device 20, so that theswitch 48 is disconnected, and themovable contact 92 is kept. in the disconnected position.

当操作手动操作钮61使操作机构60合闸时，开关48接通，使控制电源端子108向电磁铁40供电，电磁铁40通电后吸合，传动装置20受其复位力和弹簧15的作用力共同驱动向上转动，触头支持11向上移动，使动触头92从断开位置转换到闭合位置，主电路接通。When operating themanual operation button 61 to close theoperating mechanism 60, theswitch 48 is turned on, so that the controlpower supply terminal 108 supplies power to theelectromagnet 40, and theelectromagnet 40 pulls in after being energized, and thetransmission device 20 is affected by its reset force and thespring 15 The force is jointly driven to rotate upward, and thecontact support 11 moves upward, so that themovable contact 92 is switched from the open position to the closed position, and the main circuit is connected.

控制电源端子108只要出现人为断电、或者操作机构60人为分闸、或者脱扣器50发出跳闸指令使操作机构60跳闸中的一种或多种情况时，动触头92都会从闭合位置转换到断开位置，使主电路断开。具体动作过程是，当控制电源端子108人为断电，电磁铁40断电释放，电磁铁40压住并驱使传动装置20向下转动，触头支持11向下移动，使动触头92从闭合位置转换到断开位置，主电路断开。当人为操作手动操作钮61使操作机构60分闸时，开关48断开，电磁铁40断电释放，操作机构60和电磁铁40压住并驱使传动装置20向下转动，触头支持11向下移动，使动触头92从闭合位置转换到断开位置，主电路断开。As long as the controlpower supply terminal 108 is artificially powered off, or theoperating mechanism 60 is artificially opened, or therelease 50 issues a trip command to trip theoperating mechanism 60, the movingcontact 92 will switch from the closed position. to the off position to disconnect the main circuit. The specific action process is that when the controlpower supply terminal 108 is artificially powered off, theelectromagnet 40 is powered off and released, theelectromagnet 40 presses and drives thetransmission device 20 to rotate downward, thecontact support 11 moves downward, and themovable contact 92 is closed from the closed position. The position is switched to the off position, and the main circuit is disconnected. When themanual operation button 61 is manually operated to open theoperating mechanism 60, theswitch 48 is turned off, theelectromagnet 40 is powered off and released, theoperating mechanism 60 and theelectromagnet 40 press and drive thetransmission device 20 to rotate downward, and the contact supports 11 Moving down, themovable contact 92 is switched from the closed position to the open position, and the main circuit is disconnected.

当操作手动操作钮61使操作机构60合闸，并使动触头92处于闭合位置时，电压变换电路80向脱扣器50中的处理电路53供电，电流互感器55时时监测电路的运行状况，把监测到的故障信号传送给处理电路53进行分析处理，并在过载/短路电流出现时，处理电路53向磁通适配器52发出跳闸指令，驱动操作机构60动作，然后使开关48断开，电磁铁40断电释放，操作机构60和电磁铁40压住传动装置20并使其向下转动，触头支持11向下移动，使动触头92从闭合位置转换到断开位置，主电路断开。When themanual operation button 61 is operated to close theoperating mechanism 60 and the movingcontact 92 is in the closed position, thevoltage conversion circuit 80 supplies power to theprocessing circuit 53 in therelease 50, and thecurrent transformer 55 constantly monitors the operation status of the circuit , transmit the monitored fault signal to theprocessing circuit 53 for analysis and processing, and when the overload/short circuit current occurs, theprocessing circuit 53 sends a trip command to themagnetic flux adapter 52, drives theoperating mechanism 60 to act, and then makes theswitch 48 disconnected, Theelectromagnet 40 is powered off and released, theoperating mechanism 60 and theelectromagnet 40 press thetransmission device 20 and make it rotate downward, thecontact support 11 moves downward, and themovable contact 92 is converted from the closed position to the open position, and the main circuit disconnect.

在分闸或跳闸过程中，操作机构60的动作直接作用到传动装置20上，由于操作机构动作的起动速度要比电磁铁40动作的起动速度快得多，所以本发明的具有控制和保护功能的开关电器的开断性能很强，它不仅具有断路器所具备的控制和保护功能，而且还具有断路器所具备的快速分断能力。In the process of opening or tripping, the action of theoperating mechanism 60 directly acts on thetransmission device 20. Since the starting speed of the operating mechanism is much faster than that of theelectromagnet 40, the present invention has control and protection functions. The breaking performance of the switching device is very strong. It not only has the control and protection functions of the circuit breaker, but also has the rapid breaking capacity of the circuit breaker.

在合闸过程中，动触头92向静触头93闭合所需的作用力由弹簧15提供，因此，本发明的具有控制和保护功能的开关电器的合闸速度不仅快捷、而且还很稳定，所以它还具有了接触器所具备的可频繁操作的性能。During the closing process, the active force required for the closing of the movingcontact 92 to thestatic contact 93 is provided by thespring 15. Therefore, the closing speed of the switching device with control and protection functions of the present invention is not only fast, but also very stable. , so it also has the frequent operation performance of the contactor.
