一起零序过压保护动作后的分析

Analysis after the zero-sequence over-voltage protection action

零序过压保护作为变压器非有效接地的后备保护能很好的保护变压器,避免变电器中性点因绝缘问题而造成损坏。通过分析一起零序过压保护动作情况,结合实际情况,说明零序过压保护重要性以及在使用零序过压保护时一些注意环节。

Zero-sequence over-voltage protection for transformer non effective grounding transformer backup protection could be a very good protection,avoided the transformer neutral point the damage caused by insulation problems. By analyzed the zero sequence overvoltage protection movement situation,combined with the actual situation,showed zero sequence over-voltage protection importance and some attention in the use of zero sequence over-voltage protection.
