摘要
阐述了110 kV变压器中性点绝缘及接地方式,对系统单相接地故障时变压器中性点过电压情况进行了分析,探讨了110 kV变压器中性点过电压保护的配置及整定原则。
This paper illustrates the mode of insulation and grounding of the 110 kV transformer neutral point,analyses the over-voltage of the transformer neutral point when the system has single-phase-to-ground fault and discusses the configuration and setting principles in the over-voltage protection of 110 kV transformer neutral point.
