Transform-based power distribution station room partial discharge defect detection method

The invention relates to a transformer-based partial discharge defect detection method for a power distribution station house, and the method comprises the steps: firstly constructing a partial discharge signal enhancement method of a confidence interval theory, and carrying out the enhancement of an original signal; then constructing a partial discharge characteristic graph; extracting frequency domain characteristics of the power distribution station room sound signals by adopting a Mel-frequency cepstrum coefficient; then, the frequency domain features are input into a discharge time sequence information feature extraction model of transformer to extract time sequence features; and finally, fusing the partial discharge characteristic graph and the time sequence characteristics, and jointly analyzing the partial discharge type of the power distribution station house, thereby realizing high-accuracy detection of the partial discharge of the power distribution station house. 本发明涉及一种基于transformer的配电站房局部放电缺陷检测方
