摘要
对110 kV主变压器油色谱异常数据进行了分析,结合电气试验对故障性质及具体位置进行了判断,查明该主变油色谱数据异常由高压套管末端均压环脱落引起放电所致,将均压环紧固处理后主变压器正常运行。
The abnormal oil chromatographic results of a 110 kV main transformer are analyzed. The nature of the fault and fault position are diagnosed based on electrical test. It is found that the anomaly is caused by the discharge after grading ring dropped at the end of the high voltage bushing. After tightening up the ring, the operation of transformer gets back to normal.
