ABB保护跳闸出口自保持继电器监视功能的实现

Implementation of Monitoring on Outlet Latching Relay for ABB Protective Tripping

针对变电站缺乏各出口跳闸自保持继电器是否复归的监视,当进行保护联动试验时,可能造成开关误跳闸事故的情况。提出了1种可靠的解决方案,实现了出口跳闸自保持继电器的监视功能。实践证明,该方案具有一定的实用价值。

Aiming at lack of monitoring on outlet latching relay of ABB protective tripping in substations, which may cause mistrip of switches in case of protective linkage test. The paper proposes a reliable solution, which implements the monitoring on outlet latching relay of protective tripping. It is practically proved that the solution is of use value.
