摘要
介绍了一起500kV主变夹件接地故障的分析与现场处理。当主变夹件接地故障后，在不具备彻底消除故障的情况下，通过对故障性质及故障原因的综合分析，应采取串入电阻的方法来限制接地电流。反之，应彻底消除故障。
The paper introduces the treatment and analysis of the clamp grounding fault of the 500kV main transformer： After the clamp grounding fault, when the fault having not eliminated thoroughly, through analyzing the characteristic and reason of the fault, the resistances should be put in serious to confining the grounding current. On the contrary, the fault must be eliminated completely.
