摘　　要：为了研究断路器分、合闸过程的动态特性,笔者针对一台配永磁操动机构的真空断路器,基于虚拟样机技术建立了断路器的动力学模型,推导出模型动作过程所满足的运动方程及电磁方程,对真空断路器的分闸、合闸动态过程进行仿真分析与实验对比。仿真和实验结果表明,模型的动态特性满足断路器的技术参数及实验数据的要求,为研究断路器的优化设计和故障诊断提供了依据。To understand the dynamic characteristics of circuit breakers in opening and closing processes, a dynamic model of a vacuum circuit breaker with permanent magnetic actuator is established based on virtual prototype technology. Kinetic equations and electromagnetic equations of the model are deduced. The opening and closing dynamic processes of the vacuum circuit breaker are analyzed via simulation and experiment, and the results show that the dynamic performance of the model meets the requirements of technical parameters and experimental data for the vacuum circuit breaker. This study may provide a basis for optimization design and fault diagnosis of the circuit breaker.
