Abstract

The invention discloses an efficient elevator energy-saving device. The efficient elevator energy-saving device comprises a motor, a power supply network, a brake resistor, an IPM elevator energy-saving device, an inverter bridge, a direct current bus, a rectifier bridge and current-using equipment, wherein the inverter bridge is used for providing direct current for the motor, and transmitting regenerated electricity generated by the motor to the direct current bus; the direct current bus transmits electric energy to the brake resistor; the brake resistor is a carrier of regenerated energy of the motor; the IPM elevator energy-saving device is used for absorbing and storing the regenerated energy received by the brake resistor; and the rectifier bridge is used for converting alternating current provided by the power supply network into direct current and transmitting the direct current to the direct current bus. According to the efficient elevator energy-saving device, the IPM elevator energy-saving device provided by the invention replaces a brake unit of the prior art, energy originally consumed on the brake resistor is quickly fed back to the network to be utilized by devices around a local area network, and the problems of energy waste of the elevator and high temperature are solved.

Description

technical field [0001] The invention relates to an elevator device, in particular to a high-efficiency elevator energy-saving device. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, used for multi-storey buildings to take advantage of people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. According to the speed, it can be divided into low-speed elevators (below 4 m / s), fa...
