[0025] A horizontally movable adjusting pressure block 6 is arranged in the adjusting cavity 4, one side of the adjusting pressure block 6 is rotatably connected to an adjusting connecting rod 7, one end of the adjusting connecting rod 7 away from the adjusting pressure block 6 is rotatably connected to a movable pressure plate 8, an opening is arranged on the top of the mounting base 1, one end of the adjusting connecting rod 7 extends to the outside of the mounting base 1, and the movable pressure plate 8 is arranged above the mounting base 1.

[0026] like Figure 1 and Figure 3 The mounting base 1 can provide support for the dry-type power transformer from below, the adjustment cavity 4 is a rectangular cavity, the protective frame 3 is a metal frame, the adjustment pressure plate 5 is horizontally arranged, and the movable pressure plate 8 can pass through the opening at the top of the mounting base 1, so that the movable pressure plate 8 is located above the mounting base 1 and can also be pressed into the interior of the adjustment cavity 4.

[0027] A columnar component 9 is disposed at one end of the adjusting connecting rod 7 , and an inclined surface is disposed at one side of the adjusting pressing block 6 , and the columnar component 9 and the inclined surface of the adjusting pressing block 6 are in conflict with each other.

[0028] like Figure 3 The cylindrical component 9 at one end of the adjusting connecting rod 7 is in contact with the adjusting pressing block 6 to reduce the friction between the adjusting pressing block 6 and the adjusting connecting rod 7 when the adjusting pressing block 6 moves.

[0029] A guide rod 10 is fixedly connected between the two sides of the inner wall of the adjustment cavity 4 , the adjustment pressure block 6 and the guide rod 10 are slidably connected, a return spring 11 is fixedly connected between the adjustment cavity 4 and the adjustment pressure block 6 , and the return spring 11 is sleeved on the guide rod 10 .

[0031] A raised plate 12 is disposed on the mounting base 1 , and a fixing hole 13 is formed on the raised plate 12 .

[0032] like Figure 1 The fixing hole 13 is a screw hole, and the external dry-type power transformer can be passed through by bolts and connected to the fixing hole 13 to fix the dry-type power transformer above the mounting base 1.

[0033] A vertical cavity 14 is provided in the mounting base 1 , a lateral protrusion 15 is fixedly connected to one side of the protective frame 3 and located in the vertical cavity 14 , a pressure spring 16 is fixedly connected to the top of the lateral protrusion 15 , and the top of the pressure spring 16 is fixedly connected to the top of the inner wall of the vertical cavity 14 .

The movable pressure plate 8 moves downward and squeezes and pushes the adjusting pressure block 6 through the adjusting connecting rod 7. The adjusting pressure block 6 moves in the direction of the adjusting pressure plate 5 and squeezes the adjusting pressure plate 5, so that the adjusting pressure plate 5 moves upward. The adjusting pressure plate 5 drives the protective frame 3 to move upward, and the protective frame 3 rises to the outside of the mounting base 1, covering the four sides of the dry-type power transformer from the outside, thereby improving the stability of the dry-type power transformer after installation.

[0039] Compared with the related art, the installation base of a dry-type power transformer provided by the utility model has the following beneficial effects:
