摘要
通过分析几起非典型变压器故障的案例,得出了变压器运行时油中溶解气体的某些变化与变压器内部过热和放电故障并不存在必然联系的结论,同时指出了气体发生变化的原因,并提出了处理的方法.
Several cases of untypical transformer fault are presented.Through analysis it is concluded that,there is not inevitable contact between some of the changes of gases dissolved in run transformer and internal overheating or discharge fault in the transformer.The causes for producing gas and the methods of treatment are put forward.
