In addition, a reinforcement component is arranged on the rear side of the outer shell, which is mainly welded by transverse reinforcement ribs and longitudinal reinforcement ribs to form a rectangular grid-like reinforcement rib structure to improve the structural strength of the outer shell. Moreover, the transverse reinforcement ribs and the longitudinal reinforcement ribs are copper tubes with excellent thermal conductivity. Through holes are provided on the longitudinal reinforcement ribs to increase the contact area between the inside and outside of the copper tube and the space, thereby improving the heat dissipation effect brought about by air convection and bringing better prospects for use. However, the disassembly and assembly of the three-phase dry-type transformer is cumbersome and inconvenient during disassembly and assembly, and the three-phase dry-type transformer has poor protection during use and is easily damaged by bumps.
