The invention discloses a partial discharge defect type identification method and device, equipment and a storage medium. The method comprises the following steps: collecting a partial discharge signal of a target defect object; converting the partial discharge signal into a pulse sequence phase distribution image; establishing an image enhancement model, and determining a target alpha parameter and a target beta parameter in the image enhancement model based on the fitness function; performing adaptive image enhancement on the pulse sequence phase distribution image based on an image enhancement model to obtain an enhanced pulse sequence phase distribution image; and determining the partial discharge defect type based on the enhanced pulse sequence phase distribution image. Through the technical scheme of the invention, adaptive image enhancement can be carried out on the PRPS image, the contrast ratio of the PRPS image is improved, the image is clearer, image features with more difference can be further ext
