Problems solved by technology

The disadvantage of this method is that there are many cables and wires, resulting in higher material costs; when the power demand is large, it is necessary to continue to increase the number of wires to ensure normal operation
In addition, the power line belongs to the power transmission with high power, and the communication with the control signal (weak current signal) in the accompanying cable will cause long-distance transmission interference

Abstract

The invention relates to a power supply unit of an elevator car, which comprises an elevator running power generator for converting kinetic energy generated from the up and down movement of the elevator car into electric energy and also comprises an electric energy control device and an energy storage unit which are electrically connected with the elevator running power generator in sequence, wherein the electric energy control device is also electrically connected with an elevator car power consuming unit, and the elevator running power generator is a diversion sheave arranged on the top of the elevator car and having the function of generating power by cutting a magnetic line of force during rotation. Compared with the prior art, the invention reduces a part of traveling cables for delivering electric power to the elevator car, reduces communication jamming caused by the hybrid transmission of strong current and weak current, improves the reliability of a controlled signal, and reduces the energy consumption.

Description

technical field [0001] The invention relates to a power supply device, in particular to a power supply device for an elevator car. Background technique [0002] Generally, the car of an elevator needs to provide power to meet the needs of equipment such as car lighting, ventilation, door mechanism switches, air conditioners, etc. under normal operation. ) are transmitted through the wires within the cable. The disadvantage of this method is that there are many cables and wires, resulting in high material costs; when the power demand is large, it is necessary to continue to increase the number of wires to ensure normal operation. Also, the power line belongs to the power transmission with relatively high power, and the communication with the control signal (weak current signal) in the accompanying cable will cause long-distance transmission interference. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to p...
