浅谈重合闸装置及闭锁重合闸压板OA
Preliminary Discussion on The Reclosing Device and Blocking Reclosing Plate
输电线路上有90%以上的故障都是瞬时性的故障，据统计，重合闸的成功率在80%以上。使用自动重合闸装置保证系统安全稳定运行。但是，随着全社会对供电可靠性的要求不断提高，也随着带电作业的推广和广泛开展，目前经常需要临时退出线路重合闸。对于110 kV线路（只讨论架空线路），按照目前常规的做法是退出重合闸出口压板和投入闭锁重合闸压板。但是在带电作业工作完毕后，运行人员有漏退闭锁重合闸压板的可能，使得线路在故障跳闸后不能自动重合闸，不能保障对用户的供电。…查看全部>>
More than 90%of transmission line fault is instantaneous fault. According to statistics,the successful rate of reclosing is more than 80%. Using the automatic reclosing device can ensure safe operation of the system. But,as the demand on the reliability and safe of power system have been improved, as Live Working widely developing, it is necessary to exit the reclosing device temporarily and frequently. Such as 110kV transmission line(the paper only talk abo…查看全部>>
