State detection method and device of power equipment, equipment and storage medium

The invention relates to the field of power equipment detection, and discloses a power equipment state detection method and device, equipment and a storage medium, which are used for improving the detection accuracy. The power equipment state detection method comprises the steps that an initial to-be-detected image and an initial standard image of target power equipment are acquired, the target power equipment in the initial standard image is in a normal working state, the initial to-be-detected image and the initial standard image are subjected to offset correction, and the aligned target to-be-detected image and target standard image are obtained; and inputting the target to-be-detected image and the target standard image into a trained twin change detection model for detection to obtain a first calibration image, when a difference region exists in the first calibration image, performing main difference analysis on the first calibration image to obtain a second calibration image, and determining the state o
