一起变压器铁芯接地故障的分析及处理

Analysis and Treatment of Transformer Core Multiple Earthing Fault

介绍了一起运行中的变压器出现铁芯对地绝缘电阻严重降低、轻瓦斯频繁动作的故障,分析了故障发生的原因,阐述了电力变压器铁芯接地故障的诊断和处理方法,并提出相应防范措施。

Frequent action fault of a light gas relay,which is caused by the insulation resistance reduction of the operating transformer core against earth,is introduced in this paper.The diagnosis and treatment of the transformer core grounding fault are illustrated and precautionary measures are also proposed.
