摘　　要：通过对固体绝缘老化诊断方法的对比,得出检测电力变压器油中糠醛浓度是评价固体绝缘老化状态的有效方法之一,并且通过对油中糠醛含量以及溶解气体含量的测定对变压器固体绝缘老化故障进行综合的诊断。Contrasting the insulation aging diagnosis methods for the detection of solid, it＇s concluded that the furfural content in transformer oil is one of the effective methods for evaluating solid insulation aging state. And through the determination of furfural content and dissolved gas content in oil, the paper does a comprehensive diagnosis for the fault of solid insulation aging of transformer.
