摘　　要：输电线故障中90%是瞬时故障,自动重合闸系统正是在输电线发生瞬时故障后将断路器按需要自动合闸并重新投入工作的电气装置。文章设计的自动重合闸系统是基于C8051F120单片机检测外部总回路和断路器回路状态,再根据当前已合闸的次数向外部电路发送自动合闸信号。Instantaneous fault accounts for 90% of the transmission lines fault. After the transient failure of the transmission line, the circuit breaker is automatically reclosed as required by automatic reclosing. Automatic reclosing system is designed by C8051F120 MCU in this paper, first of all, the MCU detects the state of the external general circuit and circuit breaker, and then according to the closed times,the MCU sends an automatic closing signal to external circuit. It is proved that the system is reliable.
