Abstract

The invention discloses a contact type elevator power transmission system. The system comprises a storage battery arranged on a car and used for supplying power for an electric load in the car, and the system further comprises a plurality of first contact plates on an elevator shaft wall and a second contact plate on the car of the elevator, wherein the plurality of first contact plates, through an electronic switch controlled by a door open/close in place signal of each floor, are connected with a rectification circuit electrically connected with a commercial power, the second contact plate is connected with the storage battery, and a contact of the second contact plate is electrically connected with the contacts of the first contact plates. The contact type elevator power transmission system can be electrically connected with the second contact plate through the first contact plates by adopting the electronic switch controlled by the door open/close in place signal of each floor when the door of the elevator opens, so that the commercial power charges the storage battery on the car, and the storage battery supplies power for the electric load in the car, in this way, the number of cores of wires in a traveling cable of the elevator is reduced, and simultaneously, interference of the electromagnetic field generated by a power line to the control signals in the traveling cable is avoided.

Description

technical field [0001] The invention relates to a power supply system, in particular to a contact power supply system for an elevator car. Background technique [0002] Currently the power supply to the elevator car is connected to the mains through the power line of the traveling cable. Compared with other signal lines, the power line is relatively large, and it is easy to generate an electromagnetic field in the elevator shaft, thereby causing interference to other control signals. At the same time, the power supply through the accompanying cable also increases the number of cores of the accompanying cable, which increases the cost of the elevator. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elevator power transmission system that reduces the number of accompanying cable cores, reduces control signal interference factors and reduces costs. [0004] In order to solve the problems of the technologies des...
