[0031] The main unit 100 includes a transformer body 101, a base 102 fixedly disposed on the bottom surface of the transformer body 101, and a sealing sleeve 103 fixedly disposed on the bottom surface of the base 102;

[0033] The heat dissipation unit 300, which is provided on the side of the main body unit 100, includes a frame part 301 and a control part 302 located on its side. The heat dissipation unit 300 also includes a heat dissipation component 303. The heat dissipation unit 300 is used for heat dissipation operation of the transformer body 101.

Unlike the previous embodiment, the frame part 301 includes two connecting plates 301a that are clamped on the left and right end faces of the transformer body 101. The two connecting plates 301a and the inner walls of the front and rear ends of the transformer body 101 are provided with fixing bolts 301b.

[0037] Specifically, the control unit 302 includes a first motor 302a fixedly connected to the inner wall of the device plate 301c. The output rod of the first motor 302a extends through the inner wall of the device plate 301c to the outer side of the device plate 301c and is fixedly connected to a retaining ring block 302b. A retaining rod 302d is slidably connected to the inner wall of the fixing plate 301d. The top surface of the retaining rod 302d and the side of the retaining ring block 302b are in pressure contact.
