摘要
提出一种能充分利用电气试验与油中溶解气体分析结果中的有效信息进行电力变压器绝缘故障综合诊断的新方法。故障诊断过程分为物理征兆的识别与故障部位的确定两部分 ,然后分别对其中应用的故障诊断方法进行优化 。
A novel method on synthetic diagnosis for insulation fault of power transformer is put forward, in which the effective information from electrical tests and analysis result of the dissolved gas in the oil can be fully utilized. In this method the fault diagnosis is divided into two parts, i.e., the identification of physical sign and the confirmation of faulty position, then the diagnosis methods applied to them are separately optimized. Thus, the accuracy of synthetic diagnosis is effectively improved.
