摘　　要：针对现有微型断路器分励脱扣器的不足,设计出性能良好和保护功能完善的脱扣器是改进微型断路器的确良一项重要内容。分析了预付费微型断路的断电动作过程和详细工作过程。在工作过程分析的基础之上,建立了预付费微型断路器分励脱扣器的动磁铁瞬间动作的动态数学模型。从电路原理图仿真结果来看,此分励脱扣器的电路设计是完全能够满足所需要求的。To the defect of existing miniature circuit breaker with shunt release, it is important to design shunt release of nice performance and perfect protection function that improves miniature circuit breaker.Working process and acting procedure which are cut off momently are analyzed in detail. Immediate action mathematical model of moving-magnet is established that is component of prepayment meter miniature circuit breaker. From simulation result, this paper draws a conclusion that circuit design of shunt release is satisfied with requirement.
