Description

A kind of lift energy feedback energy storage power save circuit
Technical field:
The utility model relates to a kind of elevator energy tank circuit.
Background technology:
The elevator that frequency converter drives zero load up or fully loaded descending in electrical motor be operated in regenerative power generation state, the regenerative electric energy that produces is transferred on the frequency converter DC side filter capacitor, produce the pump up voltage, and IGBT, the insulation that IPM equipower binistor withstand voltage lower, too high pump up voltage may be damaged binistor, chemical capacitor even be destroyed motor threatens the trouble free service of elevator.For reducing this voltage, existing elevator adopts the resistance braking mode: by external Power Resistor, this regenerative electric energy is consumed on resistor.But resistance braking has following shortcoming: (1) wastes energy, has reduced the efficient of system.(2) the resistor heats up amount is big, worsens the control housing ambient temperature, influences the normal operation of control system miscellaneous part.(3) easily produce impact phenomenon during snap catch, influence the elevator ride comfort.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, provides a kind of elevator is in the energy feedback energy storage power save circuit that the unloaded up or fully loaded regenerative electric energy that produces when descending stored or be directly used in the elevator running.
For achieving the above object, the technical scheme that the utility model provides is: a kind of lift energy feedback energy storage power save circuit includes frequency changer direct current bus, aptitude chargeable circuit, storage battery, discharge management circuit, DC-DC booster circuit and DC-AC inverter circuit.Frequency changer direct current bus, aptitude chargeable circuit, storage battery, discharge management circuit, DC-DC booster circuit and DC-AC inverter circuit from elevator control cabinet are connected successively, frequency changer direct current bus divides two-way, one the tunnel is connected with the aptitude chargeable circuit input end, another road is connected with unilateral diode D1, the mouth of DC-DC booster circuit is connected with unilateral diode D2, and the mouth of the mouth of unilateral diode D1, unilateral diode D2 and the input end of DC-AC inverter circuit connect altogether.
Described DC-AC inverter circuit is provided with two-way, and one the tunnel is the DC-AC380V output circuit, and another road is the DC-AC220V output circuit, and this two-way output can be the part consumer power supply of elevator.
The utility model is by said structure and being electrically connected, have the following advantages: when (1) has a power failure when external power grid, storage battery can be used as the UPS back-up source and powers to apparatus for controlling elevator, makes elevator run to the floor position back pullout (BPO) nearby, and is oppressive in the elevator when preventing to have a power failure.(2) energy savings is saved the electricity charge.Relatively more existing frequency-changing elevator power saving about 30% again.(3) improve building environment.Because not re-using resistor comes consumed energy, has reduced thermal radiation, has reduced the temperature rise of machine room.Intrinsic impact phenomenon when (4) not having rheostatic brake improves the elevator ride comfort.
Description of drawings:
Fig. 1 is schematic circuit diagram of the present utility model.
The specific embodiment:
Now elaborate the utility model in conjunction with the accompanying drawings:
Lift energy feedback energy storage power save circuit, include frequency changer direct current bus, aptitude chargeable circuit, storage battery, the discharge management circuit, DC-DC booster circuit and DC-AC inverter circuit. from the frequency changer direct current bus of elevator control cabinet, aptitude chargeable circuit, storage battery, the discharge management circuit, the DC-DC booster circuit is connected successively with the DC-AC inverter circuit, frequency changer direct current bus divides two-way, one the tunnel is connected with the aptitude chargeable circuit input end, another road is connected with unilateral diode D1, the mouth of DC-DC booster circuit is connected with unilateral diode D2, the mouth of unilateral diode D1, the input end of the mouth of unilateral diode D2 and DC-AC inverter circuit connects altogether. and described DC-AC inverter circuit is provided with two-way, one the tunnel is the DC-AC380V circuit, this circuit is responsible for the control system power supply to elevator, another road is the DC-AC220V circuit, its illumination to elevator of being responsible for powering, communication and fan etc.
When elevator motor runs on regenerative power generation state, voltage on the frequency changer direct current bus reaches the discharge that the above time discharge management circuit of specified value stops battery pack, DC-DC closes no-output, D1 delivers to the inversion direct current bus with the regenerative electric energy on the frequency changer direct current bus, through DC-AC output AC380V and AC220V two-way sinusoidal ac, respectively as the power supply of equipment in elevator control cabinet and the car.Simultaneously, under the effect of aptitude chargeable circuit, partly regenerative electric energy is charged into storage battery.Run on non-regenerative power generation state and operation-stopping stage at elevator motor, discharge management circuit and DC-DC start, low-voltage direct electric energy with storage battery, be transformed to the high-voltage dc voltage that is higher than frequency changer direct current bus voltage, through D2 is the inversion direct current bussed supply, through DC-AC output AC380V and AC220V two-way sinusoidal ac, respectively as the power supply of equipment in elevator control cabinet and the car, at this moment D1 oppositely ends, and prevents that the electric energy of battery pack from giving frequency changer direct current bus.
The above-mentioned description of this feedback power save circuit being carried out with reference to embodiment is illustrative rather than determinate, therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
