Description

A kind of elevator energy regeneration device of using by oneself
Technical field
The utility model relates to the personal device of a kind of elevator energy regeneration.
Background technology
Elevator is the potential energy load, in nonequilibrium condition operation (as be lower than the semi-load of up during operating mode and greater than the semi-load of descending during operating mode) and repeatedly in the retarding braking process, will produce a large amount of potential energy and kinetic energy (industry claims that this operating mode is a generating state).During the operation of elevator generating state, to satisfy the rotating speed under the given frequency, consequent power conversion is that the anti-dc-link capacitance group side that is poured into the elevator drive frequency converter is assembled the formation high voltage direct current behind the electric energy to motor by anti-dragged brake.Elevator speed is fast more, stop is high more, it is frequent more to play braking, and the electric energy that converts to is then many more.When the electric energy of accumulation surpasses certain limit, can cause system-down even burn, also can produce a large amount of hot driving contaminated environment.
Address this problem two kinds of schemes arranged at present:
First dynamic braking scheme: insert high-power resistance in drive system, with consumed energy.Studies show that the direct electric energy that consumes on brake resistance of elevator accounts for the 35%-46% of elevator wastage in bulk or weight electric energy;
It two is energy feedback schemes: adopt the active inversion technology, at the external energy feedback inversion transformation of elevator drive frequency converter DC side brake unit the energy feedback grid.
First kind of scheme cost is lower, and be technical simple.Shortcoming is that waste of energy is unfavorable for building energy-efficient society, and because brake resistance work will be distributed a large amount of heat and pernicious gas, contaminated environment;
Second kind of scheme energy-saving effect is obvious, sends electrical network synchronously back to after the energy that elevator produces can be reverse into alternating current.Shortcoming is that the quality of power supply (as waveform, synchronous etc.) of feedback grid is subjected to necessarily doubting and if the big large-scale elevator of quantity all may threaten to the safety of electrical network to electrical network loopback electric energy.In addition, energy feedback scheme will increase the buying expenses of elevator customer and user self not had actual energy-conservation being benefited.
Summary of the invention
The technical problems to be solved in the utility model is elevator frequently to be played braking, nonequilibrium condition to move the energy regeneration that produced up and down personal rather than use brake resistance to consume, and the energy of regeneration is used for the local load of elevator.
In order to solve the problems of the technologies described above, the personal device of elevator energy regeneration of the present utility model comprises elevator drive frequency converter, elevator traction machine, elevator load, elevator power failure emergency rescue device, between elevator drive frequency converter and elevator traction machine, be electrically connected controllable current transformer, the DC side of controllable current transformer is electrically connected accumulator plant, its AC side is electrically connected with elevator load, and accumulator plant is electrically connected elevator power failure emergency rescue device; Wherein controllable current transformer is made up of the inverter circuit of direction diode, insulated gate bipolar transistor (IGBT), pulsewidth width modulated (PWM) control; Accumulator plant is made up of batteries, copped wave-step-down-charging circuit, inversion-booster circuit, and copped wave-step-down-charging circuit is connected electrically in elevator drive frequency converter intermediate dc side, and inversion-booster circuit is electrically connected with elevator load; Can increase the bypass supply device in addition and be electrically connected with elevator power failure emergency rescue device and elevator load, the bypass supply device is by the control of monitoring switch.
The personal device of this elevator energy regeneration is used for elevator drive system, elevator is frequently played braking, nonequilibrium condition, and to move the energy regeneration that produced up and down personal rather than use brake resistance to consume, the energy of regeneration is used for the local load of elevator, as illumination, ventilation, communication, monitoring, control etc., play auxiliary power supply and undertake power failure emergency management and rescue power supply to the accumulator plant charging simultaneously.The utility model has been realized that the science of elevator is energy-conservation, effectively energy-conservation and has been eliminated the environmental impact that produces because of the brake resistance heat radiation, building energy conservation reduced discharging environmental protection play obvious effects.
Description of drawings
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is a schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, between elevator drive frequency converter 1 and elevator traction machine 2, be electrically connected controllable current transformer 6, the DC side of controllable current transformer 6 is electrically connected accumulator plant 3, AC side is electrically connected with elevator load 5, accumulator plant 3 is electrically connected elevator power failure emergency rescue device 4, and wherein controllable current transformer 6 is to adopt direction dynistor, IGBT to control the energy back feed device of inverter circuit as inversion components and parts, PWM.During inversion, DC side is by voltage control, and AC side directly is electrically connected with elevator load 5, is used for illumination, ventilation, communication, monitoring, control etc.Elevator energising holding state and elevator motoring condition, elevator drive frequency converter 1 bosom capacitance voltage equals to import the voltage 500V of three-phase alternating current after rectification, at this moment, does not reach design load, and controllable current transformer 6 is not worked; Under the elevator generating state, intermediate capacitance voltage raises, when pump is raised to design load 550-570V, and the switch element conducting, high voltage direct current is converted to sinusoidal 50Hz alternating current through IGBT and powers to the elevator lighting even load; Simultaneously, the chopping depressuring circuit turn-on is to battery charging.When the pump up voltage drops to design load when following, one group of change over switch is connected automatically, and batteries is powered to elevator loads such as elevator lightings after inversion boosting.Accumulator plant 3 is made as one with elevator power failure emergency rescue device 4, so batteries is being undertaken power failure emergency management and rescue function simultaneously.For improving the reliability of power supply, increase bypass supply device 7, when inversion system or battery system electricity shortage or fault, the monitoring switch conduction automatically switches to mains supply.
Our experiments show that: elevator experiment tower is equipped with a 1350Kg/3.0m/s, the elevator of 14/14/14 stop door, adopt VVVF (Variable Voltage Variable Frequency, ac variable frequency speed regulation) drives permanent magnetic synchronous traction machine, insert the energy back feed device of above-mentioned operation principle in elevator control cabinet frequency changer direct current bus both sides, elevator except that every day the staff of picking on and off duty move the 4h, adopt random walk mode 24h operation At All Other Times.Account for 40% of total run time with up-downgoing operation and up operation probability below semi-load semi-load, brakes every day about 298 times.Insert kilowatt-hour meter record elevator generating situation at the energy back feed device output, through 1 month record, the 900Kwh that generates electricity altogether, the about 30Kwh of average generating every day.Except that being consumed in 2 of the 40w illuminations of elevator own, 2 of 35w blower fans, communication, intercommunication, monitoring, and to battery charging, experimental session power failure emergency management and rescue experiment is carried out 2 times.
