Method and system for diagnosing infrared image voltage-induced heating type defects of power transformation equipment

The invention provides a method and a system for diagnosing voltage-induced heat type defects of an infrared image of power transformation equipment, and relates to the technical field of the power transformation equipment, and the method comprises the following steps: obtaining the infrared image of the power transformation equipment; identifying the infrared image by adopting a preset network model; when the region contains a porcelain bushing region and a three-phase region, accurately identifying the region of the porcelain bushing part of the infrared picture by adopting a trained rotating target detection model; acquiring the highest temperature of the power equipment and the porcelain bushing part area, automatically associating and matching similar equipment and similar parts in the three-phase area, and acquiring the relative temperature difference between similar porcelain bushing parts; performing voltage heating type diagnosis on the power equipment in the infrared image by adopting a defect diagn
