摘　　要：通常变压器发生内部故障会使变压器油或固体绝缘材料分解，产生气体并大部分溶于油中，其气体成分与变压器的内部故障性质有很大关系。针对具体故障实例，采用对变压器油中气体含量进行分析并结合电气试验判断，能比较准确判断出故障原因和定位出故障位置。Internal failures of a transformer often cause decomposition of the transformer oil and the solid insulation materials in it, producing gases which are dissolved in the oil. Contents of the gases are considerably related to the features of the internal failure. This paper, based upon a specific failure case, presents a method of gas-composition analysis combined with the corresponding electrical test, and it proves to be very effective and accurate to detect the causes of the failure and its location.
