Abstract

A kind of frequency conversion brake for elevator cabinet, it is characterised in that:The frequency conversion brake for elevator cabinet includes cabinet, it is contained in some energy feedback units and reactor in the cabinet, the energy feedback unit is parallel with one another, connected with reactor one end of the energy feedback unit, its other end is connected with frequency changer direct current bus end, the other end at the frequency changer direct current bus end is connected with the motor of elevator, the other end and line series of the reactor, the utility model passes through feedback unit, the electric energy feedback that motor is produced is to power network, solve the problems, such as the rise of decentralization process median generatrix voltage, the electric energy produced when transferring is reused as cleaning again, realize energy-conserving and environment-protective.

Description

A kind of frequency conversion brake for elevator cabinet
Technical field
The utility model is related to brake cabinet technical field, more particularly to a kind of frequency conversion brake for elevator cabinet.
Background technology
At present, in colliery frequency conversion hoist control system, motor is in generating state in decentralization, and the direct current of frequency converter is female Line voltage can be raised.To ensure the normal operation of frequency converter, frequently with resistor box, the electricity that motor is issued is passed through into resistor box Consumed in the form of heat.So, the temperature of equipment operation is not only increased, the performance of equipment is reduced.Also in vain Electric energy is consumed, it is impossible to accomplish energy-conserving and environment-protective.
Accordingly, it is desirable to provide a kind of new technical scheme solves above-mentioned technical problem.
Utility model content
The purpose of this utility model, which is to provide, a kind of can effectively solve the frequency conversion brake for elevator cabinet of above-mentioned technical problem.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that:
A kind of frequency conversion brake for elevator cabinet, the frequency conversion brake for elevator cabinet includes cabinet, is contained in the cabinet Some energy feedback units and reactor, the energy feedback unit are parallel with one another, one end and the electricity of the energy feedback unit Anti- device series connection, its other end is connected with frequency changer direct current bus end, the other end and elevator at the frequency changer direct current bus end Motor series connection, the other end and line series of the reactor.
The cuboid of the cabinet and vertical placement.
It is provided with supporting plate in the cabinet, the supporting plate is in cuboid and horizontal positioned, the supporting plate and the cabinet The inner surface of body is fixedly connected.
The energy feedback unit is located at the top of the supporting plate.
The reactor is located at the lower section of the supporting plate.
After adopting the above technical scheme, the utility model has the following advantages that:
The utility model frequency conversion brake for elevator cabinet is by feedback unit, and the electric energy feedback that motor is produced is to power network, i.e., The rise of decentralization process median generatrix voltage is solved the problems, such as, and the electric energy produced when transferring is reused as cleaning, is realized Energy-conserving and environment-protective.
Brief description of the drawings
The embodiment to the utility model frequency conversion brake for elevator cabinet is described further below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the utility model frequency conversion brake for elevator cabinet;
Fig. 2 is the cabinet internal structure annexation schematic diagram of the utility model frequency conversion brake for elevator shown in Fig. 1.
Embodiment
As shown in Figures 1 and 2, the utility model frequency conversion brake for elevator cabinet includes cabinet 1, is contained in the cabinet 1 Some energy feedback units 3 and reactor 4.
As shown in Figures 1 and 2, the cabinet 1 is in hollow cuboid and vertical placement, and the cabinet 1 is interior provided with support Plate 2, the supporting plate 2 is in cuboid and horizontal positioned, and the supporting plate 2 is fixedly connected with the inner surface of the cabinet 1.
As shown in Figures 1 and 2, the energy feedback unit 3 is provided with several, and parallel with one another, to ensure an energy Remaining can normally be used when amount feedback unit 3 is damaged, and the energy feedback unit 3 belongs to prior art, therefore herein no longer Repeat.The energy feedback unit 3 is located at the top of the supporting plate 2.
As shown in Figures 1 and 2, the reactor 4 is connected with energy feedback unit 3, and it is used for limiting short-circuit current, belongs to Prior art, therefore will not be repeated here.The reactor 4 is located at the lower section of the supporting plate 2, so as to by energy feedback list Member 3 and the barrier of reactor 4 are opened.
As shown in Figures 1 and 2, one end of some energy feedback units 3 parallel with one another is connected with reactor 4, and Its other end is connected with frequency changer direct current bus end, and the other end and the motor at the frequency changer direct current bus end are electrically connected with, institute The other end and power network for stating reactor 4 are electrically connected with.
As shown in Figures 1 and 2, the utility model frequency conversion brake for elevator cabinet is in use, when elevator declines, electricity Machine starts to generate electricity, and the electric energy of generation is transferred into frequency changer direct current bus end, is then passed to energy feedback unit 3, so After be transferred to reactor 4, be then passed in power network, so that electric energy is fully used.So far, the utility model frequency conversion Brake for elevator cabinet is finished using process description.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to In this, any those skilled in the art can readily occur in change or replace in the technical scope that the utility model is disclosed Change, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be wanted with the right The protection domain asked is defined.
