摘要
PT高压断线事故虽属少见,但在外力破坏上仍会发生。铜冶站PT高压断线系大风作用下使母线与PT间隔跨接线C相垂直引下线接头拔出所致,造成母线停电,损失严重。合理地变更PT零序电压回路接线和正确的操作,对再发生此类事故可减小事故损失。
Interruption of HT-line to PT occures sometimes even though it is rare. Phase C of HT-line to PT in Tongye substation was interrupted by wind, causing shut-down of bus-bars and heavy losses. Reasonable modification to zero-sequence voltage circuit and proper operation can minimize losses caused by faults of this kind, if it happens again.
