摘　　要：色谱分析试验发现变压器油中溶解气体含量超注意值,通过对变压器本体与分接开关油中特征气体含量的相关系数进行计算分析,判断出有载分接开关油箱存在内漏故障,停电检查证实了分析判断的准确性,总结出类似故障的分析判断经验。It was identified in the chromatographic analysis test that content of dissolved gas in transformer oil exceeded attention valueand it was concluded that the on-load tap changer oil tank had an internal leak based on calculation of and analysis on correlationcoefficient of characteristic gas content in transformer proper and tap changer oil, accuracy of which were verified in the black-outinspection. This has been gained as the experience to analyze and determine similar failures.
