永磁真空断路器应用研究

Research on the Application of Permanent-magnet vacuum circuit breakers

通过对真空开关永磁操动机构的结构和工作原理进行分析,研究了永磁操动机构的运动特性,探讨永磁机构在断路器上的应用中控制回路元件的不足,希望对采用永磁操动机构的真空断路器的使用与维护有所帮助。

Based on the analysis of the structure and working principle of vacuum switch permanent magnetic actuator, this paper studied the motion characteristics of permanent magnetic actuator, explored the shortage for controlling loop element in the application of the permanent magnetic actuator in circuit breaker, and hoped to be helpful for the use and maintenance of vacuum circuit breakers using permanent magnetic actuator.
