摘　　要：针对现阶段永磁机构接触器的分闸脉冲故障问题,设计了一种带分闸脉冲故障保护的永磁操动机构。重点对新型永磁操动机构的工作原理进行了分析,采用COMSOL仿真软件对永磁操动机构的磁场进行了分析,最后通过试验分析得出新型永磁机构的可行性。新型永磁机构具有能耗小、便于工业应用等优点,为永磁机构接触器的可靠应用提供了新的思路。A permanent magnet actuator with opening pulse fault protection was presented for solving the opening pulse fault of the permanent magent actuator. The permanent magnet actuator＇ s working principle was analyzed and the magnetic field of permanent magnetic actuator was studied by COMSOL simulation software. Through experimental analysis, the feasibility of the permanent magnet actuator was confirmed. The study solves the contactor with permanent opening pulse problem. The new permanent magnet actuator has low energy consumption, easy to use in industry. It provides a new way for reliable applications of the permanent contactor.
