摘　　要：文章针对纪村水电站#2主变压器频发"#2主变压器冷却系统故障"现象进行了测试分析,同时结合实际对故障录波数据进行了分析计算,得出了#2主变压器冷却系统Ι段电源断相相序保护器因长时间运行在谐波环境下,导致内部器件故障引起的保护器频繁动作的结论,最后提出了措施与建议。This paper analyzes and tests the fault of cooling system of #2 main transformer frequently occurred in the #2 main transformer of ji cun hydropower station, and analyzes and calculates the fault recorder data combining with the actual situation. The #2 main transformer cooling system 1 power supply broken phase sequence protector for long time operation in harmonic environment, which leads to frequent action caused by internal fault protection device of the conclusion, and finally puts forward some measures and suggestions.
