The invention discloses a transformer protection device and method, and relates to the technical field of power transformer protection. The outer surface of a coil winding in a transformer box body is monitored through a camera; the inner surface of the coil winding in the transformer box body is monitored through a photosensitive array probe board; an image recognition processing module is used for processing pictures shot by the camera; and a control module is electrically connected with the photosensitive array probe board and the image video processing module, and is used for processing data monitored by the photosensitive array probe board and the image video processing module, and monitoring the winding of the transformer through the camera and the photosensitive array probe board. The winding state of the transformer is monitored by arranging the image processing module and the control module, and the transformer is isolated from a power system by sending an alarm signal and an action signal to the win
