Optimization Design of a Permanent Magnet Actuator for 126-kV Vacuum Circuit Breaker

To satisfy the fast operating requirements for 126-kV vacuum circuit breakers (VCBs), this paper proposes a novel monostable permanent magnet actuator (PMA) with separated magnetic circuits and investigates its optimal design method. The proposed PMA is featured with an external disc spring and an a...
