摘要
对一起220 k V变压器中压侧A相套管末屏接地不良问题进行分析,详细阐述问题排查的过程和处理方法,并针对检修方面存在的问题,提出防范措施。在日常维护工作中加强对套管末屏接地情况的巡视和测温很有必要,发现有渗漏油和温度异常情况,应引起重视,结合停电查明原因,防止缺陷扩大引发事故。
In view of the A phase bushing tap grounding failure in middle of the transformer, the processing method of the problem is described in detail, and preventive measures are put forward.In the daily maintenance work, strengthening inspection and measuring temperature is very necessary for transformer bushing tap grounding. If the oil leakage or temperature anomaly is found out, close attention should be paid to it, and causes should be found out to prevent defects to expand.
