Description

technical field [0001] The invention relates to the technical field of circuit breaker control, in particular to a controller, system and method of a permanent magnet circuit breaker. Background technique [0002] A circuit breaker is a current switching device that can open and close normal and abnormal circuits. It can be used to switch on and off the load circuit. The circuit breaker has become an indispensable and very important protective device in the distribution network. [0003] At present, traditional circuit breakers are mainly divided into permanent magnet circuit breakers and spring circuit breakers. Spring circuit breakers include spring operating mechanisms, which are mechanical systems composed of complex transmission mechanisms and require more mechanical parts. High cost and lack of reliability. Compared with spring circuit breakers, permanent magnet circuit breakers contain permanent magnet mechanisms, which have the advantages of low failure rate, fast o...
