Abstract

The utility model discloses an elevator energy recovery system comprising an energy feedback device used for converting direct currents into currents which are synchronous and cophasal with a power grid source, an input end of the energy feedback device is connected with a frequency converter, and an output end of the energy feedback device is connected with the power grid source. Compared with the technology of the prior art, the elevator energy recovery system is characterized in that the energy feedback device and the frequency converter are used in a matched manner; when the elevator is running in an unbalanced manner or is slowing down for a brake stop, the frequency converter converts alternating currents generated by mechanical energy into direct currents; the direct currents are directly sent back to the alternating current power grid source through the energy feedback device, and the direct currents can be supplied to other nearby electric devices; and power grid electric energy consumed by an electromotor dragging system in unit time can be reduced, and therefore the aim of saving electric energy and protecting environment can be realized. The elevator energy recovery system is characterized by simple structure, convenience of manufacture, low cost, and wide popularization in the field.

Description

A kind of elevator energy recovery system
Technical field
The utility model is applied to elevator and uses the field, relates to a kind of with the kinetic energy or the recoverable device of the unbalanced gesture of load-carrying, the particularly a kind of elevator energy recovery system that store in running process of elevator.
Background technology
In traditional elevator operation mode of braking, provided the converter power supply of electrical control cubicles by electrical network, the transducer drive motor.When namely machine operation is at II or IV quadrant during in on-position when machine operation, potential energy when uneven consumes by the brake resistance energy transform into heat energy elevator with the kinetic energy that stores in running status or load-carrying, so not only can waste energy, also can cause thermal pollution to environment.
The utility model content
The purpose of this utility model is, a kind of elevator energy recovery system is provided.This elevator energy recovery system can reclaim the kinetic energy that stores in running process of elevator or the unbalanced potential energy of load-carrying, can reduce the waste of energy in running process of elevator and to the thermal pollution of environment.
The technical solution of the utility model: a kind of elevator energy recovery system, comprise for direct current is converted to and synchronize synchronous energy feedback device with grid sources, the input of energy feedback device is connected with frequency converter, and the output of energy feedback device connects grid sources.
In aforesaid elevator energy recovery system, described energy feedback device comprises current converter and three-phase reactor, and the input of current converter connects frequency converter, and the output of current converter connects grid sources through three-phase reactor.
In aforesaid elevator energy recovery system, described current converter comprises the full control IGBT power model of 3 groups of parallel connections, wherein entirely controls the full control IGBT power model unit that the IGBT power model comprises two series connection for every group.
Compared with prior art; the utility model is used in conjunction with by energy feedback device and frequency converter; when elevator when unbalanced operation or retarding braking stop; frequency converter is converted to direct current with the alternating current that mechanical energy produces; again by energy feedback device with the direct loopback of direct current to the AC network source; for near other power consumption equipments, make motor driving system consume the decline of electrical network electric energy in the unit interval, thereby reach the purpose of saves energy, protection of the environment.The utility model is simple in structure, and is easily manufactured, with low cost, can extensively promote in this area.
