摘　　要：为改变断路器的单一分闸特性,基于微处理器设计了断路器分闸速度模糊控制器。研究了配永磁操动机构的断路器系统电气参数与储能电容器电容量的模糊关系,形成了对断路器分闸速度的模糊控制规则,并对控制器的软硬件进行了详细设计。该控制器使用多个储能电容器进行断路器分闸操作,能够实现不同开断条件下的分闸控制。In order to change the simplex opening characteristic of circuit breaker, opening velocity controller for circuit breaker with permanent magnetic actuator is designed based on microprocessor. Firstly, the fuzzy relation between prevailing electric parameters and capability of capacitance for opening is studied and fuzzy controlling rule for opening velocity is established. Secondly, the software and hardware subsystem of the controller is designed in detail. The controller uses several capacitors to open, so it can achieve the opening control under all conditions.
