摘要
介绍了特高压与超高压变电站防误闭锁的内容、原则及实现方式,论述了二分之三接线、双母线双分段接线和单母线接线的典型防误闭锁逻辑,并针对一起500kV新建变电站200kV封闭式组合电器防误闭锁逻辑错误案例进行了分析。
The contents, principles, and implementation methods for prevention of false locking in UHV and EHV transformer substations were introduced. The typical prevention logics of false locking for 3/2 of the wiring, double-bus double-segment wiring, and single-bus wiring were discussed. And for a 500 kV newly-buih substation, the case analyses on prevention logic error of false locking in 200 kV GIS was carried out.
