Automatic transfer switching equipment(ATSE)is a kind of apparatus to ensure the continuous power supply on important occasions.The new type of ATSE relies on electromagnetic mechanism by contact system to realize transformation instead of circuit breaker.Based on work principle of ATSE,the reaction force characteristics of electromagnetic mechanism were analyzed deeply.The design method of DC electromagnetic mechanism with rapid action was studied and the structure parameters were calculated.The preliminary design was completed.The simulation models of the static and dynamic characteristics were established by multi software combined mode.The characteristics were analyzed in detail.The key factors,which have greater influence on the performance of the electromagnetic mechanism,were researched.The optimization variables,the objective functions and the constraint conditions were determined.The structure was optimized by genetic algorithm method.At last,the prototype of the electromagnetic mechanism was developed and the static electromagnetic force tester was designed.Feasibility of the design was proved by the static electromagnetic force data and the whole test result.
