摘　　要：首先介绍线路自动重合闸的分类,分析当线路两侧都有电源的情况下重合闸时检无压和检同期的配合顺序,然后介绍重合闸的启动方式,分析断路器状态与断路器位置不对应起动的方式,最后介绍重合闸前加速、重合闸后加速以及3/2接线方式,对重合闸和断路器失灵保护的要求。First, the classification of automatic reclosing of line is introduced, and the matching order of non pressure inspection and inspection in the same period is analyzed when there are power supply on both sides of the line. Then the starting mode of reclosing is introduced, and the way the state of the circuit breaker and the position of the circuit breaker should not be started is analyzed. Finally, the acceleration of the reclosure and the acceleration after the reclosing is introduced. As well as 3/2 wiring mode, the requirements for reclosing and breaker failure protection.
