基于可拓理论的变压器故障诊断

Fault Diagnosis for the Power Transformer Based on Matter Element Analysis Principle

针对油中溶解气体新导则在变压器故障诊断中存在的问题,分析了变压器故障诊断的可托理论分析方法。电力变压器故障诊断具有复杂性,各种因素的识别和故障类型的划分之间具有不相容性,应用物元分析理论,构建物元矩阵,根据计算出的关联度大小对故障类型进行可拓识别。实际算例分析,验证了本模型的有效性和可行性。

Aiming at the problem of the dissolved gas analysis new rules applied in the power transformer fault diagno- sing, a new method of matter element analysis principle decision of the power transformer fault diagnosing is pro- posed. Power transformer fault diagnosis is complex, considering the non - compatible feature between the various factors and the type of fault, applied the theory of matter element analysis construct element matrix. The effectiveness and feasi- bility of the model is verified by analysis of practical examples.
