Three-phase transformer

The utility model relates to the technical field of transformers, in particular to a three-phase transformer which comprises a case body, a three-phase transformer body is fixedly installed in the case body, a connecting shell is fixedly installed on the top face of the case body, and bottom shells are in threaded connection with the side faces of the bottom of the case body through bolts. Compared with the prior art in which heat dissipation through holes are directly adopted for heat dissipation, the computer case has the advantages that the heat dissipation effect is better, heat can be effectively prevented from being accumulated in the computer case, the heat dissipation efficiency is improved, and the heat dissipation effect is improved. Meanwhile, by arranging a storage battery pack and a solar panel, solar energy can be converted into electric energy, then power is supplied to an air blower and an exhaust fan, and then energy consumption of the three-phase transformer can be reduced. 本实用新型涉及变压器技术领域，尤其
