Description
Technical field
The utility model relates to a kind of lift facility, and 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 operational process: 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 (UPS), in order to guarantee that elevator can normally move, and all disposes backup power (as house generator) on elevator device when having a power failure; And in elevator landing process downwards; electrical motor is in generator operation state (mechanical energy changes electric energy into); electric energy by the power converter output module flywheel 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 be protected and can't normally use by et out of order.Too high in order to prevent bus 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 is released in surrounding space, 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 sinusoidal waveform of homophase feeds back to self electrical network and utilizes, but, there is critical 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 storage battery, nickel-hydrogen accumulator and cadmium-nickel storage batterys usually as the elevator backup power, 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 dissipation, therefore, use this class storage battery as backup power, its service 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 ecology environment, ultracapacitor (is called again: electrochemical capacitor) as a kind of later-model energy storage device, because store the energy force rate ordinary capacitor height of electric charge, and have that the speed of discharging and recharging is fast, efficient is high, environmentally safe, the preceence that has extended cycle life etc. and can not be substituted, some need superpower,
In the design of high efficiency solution, 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 feed and backup power, 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 saver in the elevator device and emergency source of electrical power " 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 fail).When motor load hour, ultracapacitor is in charge condition, and is big or during when power fail, 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 source of AC, elevator main power source system still depends on electrical network, and the reliability and stability of electrical network have determined the drive ability 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 feed and backup power; only under the situation of elevator generation power fail 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 plant to be set simultaneously, make power-supply system bulky; and need complex peripheral circuit such as pressure regulator, increased cost.
