储能电机时间继电器对重合闸的影响

摘要

Automatic reclosing is one of the important methods to ensure the reliability of power supply , but in some specific situations it is necessary to block automatic reclosing to protect power system and devices against the unnecessary shocking .By studying the influences of time relay of energy storage motor in circuit breaker on automatic reclosing , it is concluded that the slipped fault of time-out relay of energy storage motor can result in the opening of low -voltage lockout reclosing and the charging light of reclosing out of work , which may have some hidden troubles .The improvement measures of substation opera-tion and maintenance is put forward .%自动重合闸是保障供电可靠性的重要手段之一，但在某些特定情况下，需闭锁重合闸，以免对系统和设备造成不必要的冲击。通过断路器储能电机时间继电器对重合闸影响的研究，得出储能电机打压超时继电器滑丝故障会造成压力低闭锁重合闸的开入和重合闸充电灯不亮的结论，会留下隐患，对变电运维提出改进措施。
