Description

Double-station mechanism of motor and high-voltage circuit breaker

Technical Field

The utility model relates to a circuit breaker technical field especially relates to a motor and high voltage circuit breaker's duplex position mechanism.

Background

At present, in a double-station mechanism of a high-voltage circuit breaker, two speed reduction motors drive a turntable to rotate through the transmission of a screw nut and then drive a switch main shaft to realize switching on and switching off. The working condition that two motors require is that only one motor needs to be started at each time, the other motor is standby, the two motors all require to be capable of rotating forward and backward, however, after the switch spindle rotates in place, the motors are required to be suddenly stopped through energy consumption braking, at the moment, a large spark can be instantaneously generated between a commutator and an electric brush of the motors, air between a support and the commutator can be punctured, and the support is connected with the reduction gearbox and is installed on the switch cabinet body through screws, so that a closed loop is formed between current and the ground in the motors, leakage short circuit can be caused, tripping is caused, and therefore the problem is urgently needed to be solved.
