Mechanical Testing of a New Type Circuit Breaker''s Operating Mechanism
新型断路器操作机构的力学测试

In order to develop an operating mechanism with simple structure,low cost and little energy consumption for high-voltage circuit breaker,a new type permanent magnet operating mechanism(PMOM) is presented in this paper,based on the analysis of permanent magnet electric operation.Since the performance of PMOM is not ideal,a new type permanent magnetic drive and permanent magnetic keep operating mechanism is proposed.Moreover,the reaction force of vacuum interrupter was tested by MTS809 material testing system...
