摘要
提出了将变压器故障视为分布于实线性空间中的特征矢量 ,通过比较征兆矢量与特征矢量之间夹角的大小实现故障诊断的方法。其诊断思路新、物理意义明确、判断函数简单、诊断结果直观形象、并能对诊断模型进行修正。
This paper presents a new method of transformer fault diagnosis,whose basic thought is that transformer faults are considered as characteristic vectors distributing in real linear space,diagnostic results are concluded by comparing angle of characteristic vectors with fault symptom vector.This method has novel diagnostic thought,definite and clear physical meaning,simple diagnostic function,straightforward and visual results,and can modify fault model.Fault diagnosis examples prove that this method is effective and valuable in engineering application.
