| 摘 要： | 本文采用溶解气体色谱分析法，跟踪分析了一台有潜伏性故障220kV变压器油中溶解气体的成份、特征气体含量和变化趋势。根据试验结果提出了故障诊断的步骤和方法，首先排除非故障产气的可能性，然后根据特征气体含量进行故障性质识别，再运用三比值法判断故障类型和进行状况诊断，最后应用有关参考文献综合进行故障部位估算。经现场设备检查和故障排除证实该判断方法和结果是正确的。

| Abstract: | By dissolved gas analysis,the paper analyzed component,composition content and trend of 220kV transformer dissolved gas in oil with potential fault.According to result,diagnosis procedures are proposed: first,excluding the possibility of gas production not caused by fault,second,identifying fault by has content,third,judging the fault type by three-ration method,and the last check the fault site through reference.Field test proves the method is feasible. |
