Design and Analysis of a New Permanent Magnet Actuator for Medium Voltage Vacuum Circuit Breakers

摘要：

　　This paper proposes a bi-stable permanent magnetic actuator (PMA) for medium voltage vacuum circuit breaker.The structure of the proposed PMA is discussed and the optimization of the structure is carried out.The model of finite element analysis (FEA) is constructed where the flux distributions,electromagnetic force under different structure parameters are analyzed.The feasibility and correctness of the PMA are verified by the FEA simulation results and the optimal size for movable plunger and stationary iron ring is obtained.
