The intelligent switch is developed based on the research of infinite element method. After conducting quality and counter-force reduction,the infinite element model is built using the dynamic characteristics of the monostable permanent magnetic actuator. This article analyzes the open-and-closed action current and the travel characteristics of the monostable permanent magnetic actuator and the mechanical characteristics of the circuit breaker,and then discusses the related experimental research. In the experiment,the open-and-closed travel curves of the circuit breaker contact and the open-and-closed coil current curves of the permanent magnetic actuator are tested. The results verify the accuracy and reliability of the simulation and the excellent performance of the actuator and the circuit breaker.
