Description

Double parallel monostable permanent magnet operating mechanism

Technical Field

The utility model particularly relates to a two monostable permanent magnetism operating device that connect in parallel.

Background

Conventional operating mechanisms suitable for vacuum circuit breakers can be classified into electromagnetic operating mechanisms and spring operating mechanisms. The electromagnetic operating mechanism has a simple structure and low manufacturing cost, but the closing operation of the electromagnetic operating mechanism needs a direct-current power supply to provide a large working current in a short time, and the electromagnetic operating mechanism needs a lock catch for keeping the closing position. The spring operating mechanism stores energy by using an alternating current/direct current low-power motor, and a low-power tripping coil performs switching-on and switching-off operation, so that the requirement on the capacity of a power supply is very low, and impact current basically does not exist.

The permanent magnet operating mechanism is a novel mechanism which is switched on and off by depending on the suction force of an electromagnetic coil and is kept by permanent magnet magnetic force, and the permanent magnet operating mechanism has few parts and simple structure and is developed rapidly after being released for more than 10 years.

However, the repulsion force of the permanent magnet actuator is often limited by the volume, and when a large force is required, the volume of the permanent magnet actuator needs to be increased, which results in the volume of the entire circuit breaker becoming large.
