| 摘 要： | 通过对充油电力变压器产氢机理的分析，根据油中溶解的不同特征气体成分之间的伴生增长情况，提出一种动态识别氢气主导型故障的方法。该方法克服了以往静态分析方法受故障累积效应及测量随机误差等因素的影响，大大提高了对该类故障诊断的准确度。

| Abstract: | According to the correlation of gases with different dissolved characteristic during the course of increasing hydrogen content, a dynamic method used to recognize the hydrogen dominant fault is presented by analyzing the generating mechanism of hydrogen. The shortcoming of static method, which is affected by the random error of measurement and accumulating effect of fault, can be overcome. The precision of diagnosis on this kind of fault can be improved. |
