Description
Technical field
The present invention relates to a kind of lift facility, a kind of especially is the micro power consumption elevator of energy storage carrier with the super capacitor.
Background technology
Elevator has two states in running: i.e. " electric operation " state and " generator operation " state.In the fully loaded upwards lifting process of elevator, elevator is in motor-operated running state (electric energy changes mechanical energy into), main power source is usually by the power supply of commercial power (as the 380V alternating current) as continued power, in order to guarantee that elevator can normal flat bed when the instant cut-off, need the configuration uninterrupted power supply, in order to guarantee that elevator can normally move, and all disposes stand-by power supply (as house generator) on elevator device when having a power failure; And in elevator landing process downwards; motor is in generator operation state (mechanical energy changes electric energy into); electric energy by the power converter output module fly-wheel diode and be rectified into direct current; be added in then on the dc bus of frequency converter; the voltage of dc bus is raise; if can not in time these electric energy be discharged, elevator will break down protection and can't normally use.Too high in order to prevent busbar voltage, all be that the electric energy that sends when adopting brake unit that elevator is descended is released on the resistance in the past, this moment, electric energy changed heat energy into, and its heat release is the space around, forms secondary pollution; In like manner, unloaded uplink and downlink, on the contrary then, promptly go up the behavior generating state, following behavior motoring condition, its principle is with last identical.In recent years, then adopt the inversion feedback unit the electric energy another mistake that has discharged become with frequently, the sine wave of homophase feeds back to self electrical network and utilizes, but, there is major defect in this mode---noise and harmonic pollution power supply and surrounding space, disturb the normal operation of self system and near equipment.
At present, the elevator manufacturer uses as traditional chemical batteries such as lead acid accumulator, nickel-hydrogen accumulator and nickel cadmium cells usually as the elevator stand-by power supply, this class batteries to store energy is the chemical reaction that relies on electrode, and dynamic performance is relatively poor, the mechanical energy storage in the time of can not guaranteeing timely and effectively elevator to be descended, cause energy waste, therefore, use this class storage battery as stand-by power supply, its useful life is short, need periodic replacement, also can cause certain pollution environment.Along with The development in society and economy, people more and more pay close attention to for green energy resource and biological environment, ultracapacitor (is called again: electrochemical capacitor) as a kind of novel energy storage device, because the energy force rate ordinary capacitor height of store charge, and have that the speed of discharging and recharging is fast, efficient is high, environmentally safe, the superiority that has extended cycle life etc. and can not be substituted, need in the design of high power, high efficiency solution at some, the engineer has begun to adopt ultracapacitor to replace traditional battery.
If any the patent No. is that the Chinese invention patent " a kind of novel energy-conserving elevator " of ZL200410054284.9 discloses a kind of use ultracapacitor as accessory power supply and stand-by power supply, ultracapacitor can effectively be released energy and energy storage when elevator starts and descend, reach purpose of energy saving; Simultaneously, can guarantee that elevator will be trapped near passenger in the elevator floor being transported in the power cut-off incident safely in burst.And for example to be that 200580023344.3 Chinese invention patent " as the power supply of energy-saving appliance in the elevator device and emergency power supply " discloses a kind of with the method and apparatus of the required power storage of elevator device in the ultracapacitor for application number, and ultracapacitor can be used as the redundant electrical power under the emergency condition (as power failure).When motor load hour, ultracapacitor is in charged state, and is big or during when power failure, ultracapacitor release electric energy is used for motor when motor load.But, in above-mentioned two patents, giving the main power source of elevator continued power still is traditional AC power, elevator main power source system still depends on electrical network, and the reliability and stability of electrical network have determined the runnability of elevator, in the most of the time of the normal operation of elevator, ultracapacitor is not worked, the energy that is stored in the super capacitor also must discharge after being full of electricity, or adopts the storage battery secondary to store, and causes resource and waste of electric energy; In addition; above-mentioned patent is because ultracapacitor only uses as accessory power supply and stand-by power supply; only under the situation of elevator generation power failure or outage, just give elevator supply; ultracapacitor stores the electric energy of elevator generation in service; though reached the purpose that protection main power source and electric energy feedback utilize, on the elevator main power equipment and auxiliary power unit to be set simultaneously, make power-supply system bulky; and need complex peripheral circuit such as voltage regulator, increased cost.
