摘　　要：变压器的过热故障在变压器运行故障中占很大比例,它会严重影响变压器的正常运行。通过气相色谱对一台66 kV主变压器的油气体分析发现内部存在过热性故障,结合其他电气预防性试验数据,经过综合分析和查找确认,找出了与实际相符的故障部位,排除了潜伏性故障。Overheating fault makes up a large proportion in transformer operation. It will seriously affect normal operation of the transformer. The oil gas in the 66 kV main trans- former was analyzed by gas chromatography. It had found out that there was an overheating fault inside the transformer. According to other electrical preventive test data and comprehensive analysis, the fault position was found out and potential faults were eliminated.
