Electrical equipment fault diagnosis method and device, electronic equipment, storage medium and computer program product

The invention discloses an electrical equipment fault diagnosis method and device, electronic equipment, a storage medium and a computer program product. The method comprises the following steps: acquiring a data image; the data image is an image representing the electrical performance of the electrical equipment; performing feature extraction and feature fusion on the data image to obtain an initial fusion feature vector; inputting the initial fusion feature vector into a first neural network model to obtain a first feature vector; inputting the initial fusion feature vector into a second neural network model to obtain a second feature vector; performing feature fusion on the first feature vector and the second feature vector to obtain a target fusion feature vector; and inputting the target fusion feature vector into a third neural network model to obtain a target feature vector, and obtaining a fault defect rate according to the target feature vector, thereby improving the accuracy and robustness of electr
