Transformer winding state determination method and device and transformer

The invention discloses a transformer winding state determination method and device and a transformer. The method comprises the following steps: carrying out de-noising processing on a vibration signal of a transformer to obtain a de-noised vibration signal; performing feature extraction on the denoised vibration signal from a plurality of feature extraction dimensions to obtain a plurality of feature values of the vibration signal; and inputting the plurality of characteristic values into a winding state evaluation model to process the plurality of characteristic values by using the winding state evaluation model to obtain the winding state of the transformer, the winding state evaluation model being obtained by using multiple groups of training data through machine learning training. Each group of the plurality of groups of training data comprises a characteristic value and a winding state corresponding to the characteristic value. According to the invention, the technical problem that the operation state o
