摘　　要：自动重合闸设备广泛应用于电力线路中,尤其是在瞬时故障的情况下。继继电器之后,继电器由自动重合闸设备重合闸,对缩短供电时间,提高供电可靠性具有重要意义。在110 kV及以下的输电线路系统中,最常见的是一侧输电线路和两边输电线路的三相自动重合闸。规划了一种电力系统三相自动重合闸计划。配电线路故障后,继电保护跳闸断路器。通过一定的时刻距离后,自动重合闸设备能够重新衔接断路器,然后有效削减不必要的断电和故障,确保电力系统的功耗,具有连续性、安全性和可靠性。Active reclosing equipment is widely used in power lines,especially in the case of transient faults.After the relay,the relay is reclosed by the active reclosing device.It is of great significance to shorten the power supply time and improve the reliability of power supply.In the transmission line system of 110 kV and below,the most common is the three-phase active reclosing of the transmission line on one side and the transmission line on both sides.This paper plans a three-phase active reclosing plan for power system.After the distribution line fails,the relay protection trips the circuit breaker.After a certain time distance,the active reclosing device can reconnect the circuit breaker,and then effectively reduce unnecessary power outages and faults to ensure the power consumption of the power system.Continuity,safety and reliability.
