摘要
阐述了冶金企业自发电并网变压器在特殊工况运行情况下,通过色谱异常跟踪分析和直流电阻试验数据诊断,判断一起引线断股故障点位置并提出解决问题的处理措施,及时消除了并网变压器隐患缺陷。
Under the special operating conditions of grid-connecting transformer for self generated power in the metallurgical enterprise, the method of tracking analysis of abnormal chromatogram and diagnosis of DC resistance test data was used to judge the position of a broken wire fault point and treatment measures to solve the problem were put forward,which eliminated the hidden defects of the grid-connecting transformer in time.
