Description

technical field [0001] The invention relates to the technical field of circuit breaker control, in particular to a circuit breaker control device and system. 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 load circuits, and can also be used to control motors that start infrequently. Circuit breakers have become indispensable and very important in distribution networks. Important protection electrical appliances. [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,...
