摘　　要：利用变压器油中溶解特征气体的组分及含量可识别变压器潜伏性的故障。基于某大型变压器总烃含量增高的原因分析和处理过程,通过产气速率计算、三比值法,结合电气试验,潜油泵检查等方法准确判断变压器故障类型,故障最终得到有效处理。The composition and content of dissolved characteristic gases in transformer oil can be used to identify latent faults of the transformer.The abnormal increase of the total hydrocarbon content in a large-scale transformer is analyzed.Based on the gas production rate values,the three ratio method,electrical tests and submersible pump inspection,the type and possible reasons of the fault are determined.After treatment,the fault is successfully resolved.
