Abstract
The utility model discloses an electric energy collection and storage system for power generation of an electric elevator. The electric energy collection and storage system comprises an electric motor, a frequency converter, a heat radiation capacitor and a storage battery, wherein the power input end of the frequency converter is connected to commercial power; the power output end, the electric energy collection end and the control end of the frequency converter are all connected with the electric motor; the heat radiation capacitor is connected with the frequency converter; and the storage battery is connected with the frequency converter. The electric energy collection and storage system is simple in structure and realizes energy recycle, thus saving the energy.
Description
Technical field
The utility model relates to a kind of electricity collection memory system, particularly a kind of electricity collection memory system of elevator generating.
Background technology
Elevator is the technology that a kind of electrodynamics and control combine, elevator unnecessary mechanical energy in service becomes direct current energy to be stored in the electric capacity in the direct-current loop of frequency converter by electrical motor with inverter converts, this moment, electric capacity was like being a little reservoir, the electric energy that is transmitted back in the electric capacity is more, capacitance voltage is just higher, and the electric energy as untimely releasing capacitor stores will produce the overvoltage fault, frequency converter is quit work, and elevator can't normally move.At present frequency converter is released, and the method for electric weight is in the large electric capacity, adopts brake unit and adds high-power resistance, and electric quantity consumption in the large electric capacity is wasted to adding on the high-power resistance.
At present some enterprise is attempting feeding back to electrical network, but because instantaneity and the wave band of elevator generating are unstable, therefore causes electrical network unstable and do not allow to use.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and can realize the electricity collection memory system of the elevator generating of reusing of energy source.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of electricity collection memory system of elevator generating, comprise motor, frequency converter and heat radiation electric capacity, described converter power supply input termination civil power, described converter power supply mouth, electricity collection end and control end all are connected with described motor, described heat radiation electric capacity is connected with described frequency converter, it also comprises storage battery, and described storage battery is connected with described frequency converter, is used for the electric energy that the storage motor feeds back to frequency converter.
Elevator no-load is up descending with elevator heavy duty the time, and the motor of elevator can produce electric energy and feed back in the frequency converter, holds back before electric energy is converted into heat energy, electric energy is filled in the storage battery stores, and is used for powering to miscellaneous equipment.And when accumulator failure and frequency converter opened circuit, heat radiation electric capacity entered mode of operation, made the electric energy energy transform into heat energy and discharged, and did not affect elevator and normally moved.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, realize reusing of energy source, and saved the energy.
Description of drawings
Fig. 1 is the circuit block diagram of the electricity collection memory system of elevator generating in the utility model one preferred embodiment.
The specific embodiment
Consult Fig. 1, the electricity collection memory system of this elevator generating comprises motor, frequency converter, heat radiation electric capacity and storage battery; Converter power supply input termination civil power, converter power supply mouth, electricity collection end and control end all are connected with motor, and heat radiation electric capacity is connected with frequency converter, and storage battery is connected with frequency converter.
Elevator no-load is up descending with elevator heavy duty the time, and the motor of elevator can produce electric energy and feed back in the frequency converter, holds back before electric energy is converted into heat energy, electric energy is filled in the storage battery stores, and is used for powering to miscellaneous equipment.And when accumulator failure and frequency converter opened circuit, heat radiation electric capacity entered mode of operation, made the electric energy energy transform into heat energy and discharged, and did not affect elevator and normally moved.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
