摘　　要：电力变压器是电力系统的枢纽设备,其可靠性直接影响到电网的安全稳定,油中溶解气体分析是一种较好的监测和诊断变压器故障的方法。结合一起变压器绝缘油色谱数据异常的案例,通过油中溶解气体分析和停电试验来判断变压器的绝缘故障类型,发现了变压器缺陷。Power transformers are key equipment in power system, and their operation reliability directly influences the safety and stability of power system.The dissolved gas analysis in oil is an effective measure to monitor and diagnose the faults of transformers.Taken as an example of a case of transformer insulating oil chromatographic abnormality,the fault type and fault location are determined by means of dissolved gas analysis and experiments.
