摘要
智能变电站500kV断路器液压弹簧机构压力低闭锁重合闸回路,存在一定的隐患,可能导致线路保护不能重合闸或导致重合闸的误动作,本文对液压弹簧机构闭锁重合闸回路进行分析,并提出改进方法。
There are some hidden dangersof blocking reclosure circuit of intelligent substation 500 kV circuit breaker hydraulic spring mechanism, therefore, maybe case the protection of lines are not able to reclosing or the reclosing malfunction. Now, this paper analyzes the blocking reclosure circuit and put forward some improvements.
