Abstract
The present invention relates to a novel energy-saving elevator using a super capacitor. As an auxiliary power supply and a standby power supply, the super capacitor can effectively release energy and store the energy to achieve the purpose of energy saving when the elevator is started when the elevator goes down; simultaneously, the super capacitor can ensure that the elevator securely delivers passengers remaining in the elevator to a nearby floor in an accidental power-off event. A super capacitor module for the energy-saving elevator can be obtained by combining a single super capacitor and by installing a voltage equalizer to effectively operate through an intelligent control system. The method has advantages of high efficiency, ultralong service life, etc. The method has favorable popularization value.
Description
One, technical field:
The present invention relates to a kind of novel energy-conserving elevator, particularly disclose a kind of use ultracapacitor, belong to the energy and appliance field as energy-conserving elevator accessory power supply and stand-by power supply.
Two, background technology:
Stand-by power supply (Back-upPower) when generally all needing in the elevator chemical power source is installed as the burst loss of power accident at present.At present, elevator production firm adopts traditional chemical power supplys such as lead acid accumulator, nickel-hydrogen accumulator and nickel cadmium cell usually.There is certain deficiency in these storage batterys as the stand-by power supply of elevator, mainly comprise: (1) is shorter useful life, needs periodic replacement.Because chemical change can take place storage battery electrode active material in the course of the work, causes the expansion and the contraction of electrode structure, cause the accumulator property decay.The storage battery that just need more renew in common 1～3 year; (2) energy recuperation poor performance, same because batteries to store energy is the chemical reaction that relies on electrode, and its dynamic performance is generally relatively poor, therefore, the mechanical energy storage when adopting storage battery can not guarantee timely and effectively elevator to be descended causes the waste of the energy; (3) environmental pollution, most of elevator adopts be lead acid accumulator as stand-by power supply, battery in use produces a large amount of acid mists, uses the back metallic lead to be difficult for handling, and causes the pollution of heavy metal to environment.
" ultracapacitor (Supercapacitor, Ultracapacitor) ", have another name called " electrochemical capacitor (ElectrochemicalCapacitor, EC) " be a kind of novel energy storage device.The electric double layer that this device utilizes electrode active material and electrolyte to form carries out the physical charge storage and discharges, and therefore has good power characteristic, can high current charge-discharge.Simultaneously (specific area can be up to 3000m because electrode active material generally adopts the porous activated carbon of high-specific surface area
2/ g), therefore can obtain higher integrating capacitor.In addition since the electrode of ultracapacitor can the generating electrodes structure in charge and discharge process change, so it also has long-life advantage (＞100000 times).And the cleaning of ultracapacitor, advantage such as pollution-free are its favors that more and more is subjected to the consumer.
Three, summary of the invention:
The objective of the invention is to: a kind of technical scheme of novel energy-conserving elevator is provided, promptly uses accessory power supply and the stand-by power supply of ultracapacitor as elevator.
Technical scheme of the present invention is: a kind of novel energy-conserving elevator is characterized in that use accessory power supply and the stand-by power supply of ultracapacitor as energy-conserving elevator, described ultracapacitor is the assembly by the monomer series-connected combination of ultracapacitor.Determine amount of monomer according to electric pressure and ultracapacitor monomer voltage scope that elevator is used, by the work of intelligent controller control ultracapacitor assembly.The used ultracapacitor of energy-conserving elevator carries out work by the control device that is installed in the elevator.Ultracapacitor is described in ZL 02217073.1 patent, and this place is not described further.The present invention selects in active carbon/active carbon symmetric form ultracapacitor or the asymmetric ultracapacitor of nickel oxide/active carbon.When elevator started, ultracapacitor discharged storage power, provided peak power to assist the work of electrical network drive motors, and at this moment elevator rises; When elevator descended, ultracapacitor was in the energy storage state, was about to the mechanical potential of elevator when descending and was converted into electric energy, and be stored in the ultracapacitor, used during in order to elevator startup next time; When the elevator sudden power, ultracapacitor utilizes the stand-by power supply of storage power as elevator, with near the floor elevator the delivering to fast and safely and open elevator door, to guarantee to be trapped in the safety of the passenger in the elevator; When elevator is out of service, intelligent controller will be judged the charged situation of ultracapacitor, and as the need charging, intelligent controller sends instruction, by electrical network ultracapacitor is charged.
The present invention uses ultracapacitor to be as the accessory power supply of elevator and the benefit of stand-by power supply: (1) is because ultracapacitor can heavy-current discharge, needed peak power when having remedied the elevator startup, reduced network load, really accomplish " energy-conservation ": the variation of physical structure can not take place in electrode when reacted owing to electrode of super capacitor (2), its long service life need not to change and safeguard; (3) make employed material heavy metal free of ultracapacitor and noxious substance, in use with after using can not pollute environment.
Four, description of drawings:
Accompanying drawing is an operation principle block diagram of the present invention.
Five, embodiment:
According to the electric pressure of elevator electricity consumption and the monomer voltage scope of ultracapacitor, determine the quantity of monomer.The electric pressure of present embodiment elevator is 380Vac, and ultracapacitor voltage is set at 450Vdc, adopts the nickel oxide ultracapacitor, and number of monomers is 300.
According to the use power and the operating condition of elevator, guarantee when sudden power, can to have in the ultracapacitor enough energy drives elevators arrive near floor, the ultracapacitor energy storage capability should have enough surpluses.The storage power of the ultracapacitor of present embodiment is 2kwh.
The above-mentioned ultracapacitor of a plurality of performance unanimities is carried out tandem compound, form super capacitor module.The harmony of voltage when guaranteeing that capacitor is monomer series-connected, each monomer is furnished with the electric voltage equalization module, with protection ultracapacitor monomer.
The drive motors of present embodiment adopts alternating current machine, therefore, at the input and output side of ultracapacitor assembly electric current reversible AC/DC converter has been installed, and the work that discharges and recharges of ultracapacitor is controlled by intelligent controller.
Above-mentioned electric voltage equalization module and intelligent controller are produced by Shanghai and health electronics corporation, and the modularization supply; The AC/DC converter is the commercially available prod.
