摘　　要：为了能提前发现电力运行设备的隐患,预防发生事故或设备损坏,通过对设备进行的检测试验,发现问题能够提前进行处理,所以必须做电力系统预防性试验。介绍了通过变压器油样检测试验的色谱分析数据,运用三比值法,掌控变压器劣化趋势,诊断出66 kV变压器内部电弧放电故障,避免了重大设备事故的发生,证实了油色谱分析判断变压器故障的有效性。In order to be able to find the hidden problems of power operation equipment in ad⁃vance and prevent accidents or equipment damage,it is necessary to do the preventive test on power system through the detection tests of the equipment,so the problems found can be coped with in ad⁃vance.The paper introduces the use of chromatographic analysis data from the transformer oil sample inspection test to control the transformer deterioration trend by applying the three-ratio method,so as to diagnose the arc discharge fault inside the 66 kV transformer,which avoids the oc⁃currence of major equipment accidents and confirms the effectiveness of oil chromatography analysis in determining transformer faults.
