Problems solved by technology

[0003] Vacuum circuit breakers are mainly divided into spring mechanism circuit breakers, electromagnetic mechanism circuit breakers, pneumatic mechanism circuit breakers, hydraulic mechanism circuit breakers and permanent magnet mechanism circuit breakers according to different operating mechanisms. Traditional control methods such as pneumatic mechanism and electromagnetic mechanism, among which the structure and process of the spring mechanism circuit breaker are complex, the number and types of parts are various, and the mechanical failure rate is high; the drive power of the electromagnetic mechanism circuit breaker is large, the contact force is small, and The contacts are easy to jump; the cost of pneumatic and hydraulic mechanism circuit breakers is relatively high, and the requirements for manufacturability and sealing are relatively strict
