Problems solved by technology
[0003] Due to the problem of uneven impregnation in the impregnation process of the power transformer, the insulation performance of the cavity wall of the power transformer is different from the theoretical insulation performance. If the voltage is too high during use, it is easy to break down the non-impregnated or impregnated quality. parts, causing danger

The power transformer comprises a transformer body and a coil module arranged in the transformer body, an impregnation cavity for containing an impregnation frame is formed in the transformer body, the impregnation frame comprises a frame body and an extrusion assembly, a camera device is arranged on the side wall of the frame body, and the extrusion assembly is arranged on the side wall of the frame body. The camera device comprises a camera and an IPC processor. The invention specifically relates to the technical field of power transformers. According to the power transformer with the self-recovery fuse and the impregnation technology of the power transformer, in the impregnation process, an image which is not completely impregnated is picked up and collected through a pick-up and collection module, then a point cloud group is picked up in the image through an IPC processor, point cloud analysis is conducted through a core processing module, and the point cloud group of a part with low impregnation quality is extracted; and then the control unit controls the electromagnetic valve to spray the impregnation liquid in a targeted manner, so that the impregnation quality of the transformer can be improved, and the problem of transformer damage caused by uneven impregnation is avoided.
Description
technical field [0001] The invention belongs to the technical field of power transformers, and in particular relates to a power transformer with a self-restoring fuse and an impregnation process thereof. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. [0003] Due to the problem of uneven impregnation in the impregnation process of power transformers, there is a difference between the insulation performance of the cavity wall of the power transformer and the theoretical insulation performance. If the voltage is too large during use, it is easy to break down unimpregnated or impregnated with low quality. parts, causing danger. Contents of the invention [0004] The object of the present invention is to provide a power transformer with a resettable fuse and its impregnation process, so as to sol...
