[0002] In recent years, with the continuous development of domestic power equipment manufacturing technology, the size of transformers has become more and more compact. Conventional capacity ultra-high voltage power transformers have optimized the original cooling structure of the oil guide mother pipe and the plate disperser, and are using a structure in which the plate disperser is directly installed on the wall of the power transformer oil tank. This structure eliminates the oil guide mother pipe, the product appearance is more concise, the product occupies less space, the user's maintenance workload is lower, and the manufacturing unit also reduces the manufacturing cost, making the power transformer more cost-effective.
