[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a pull plate embedded with a copper bar pad, comprising a pull plate 1 and a pad 2, the pull plate 1 is provided with a plurality of symmetrical rows of slots 3, the pad 2 is inserted into the slots 3, and the pad 2 and the slots 3 are clearance-matched.

[0025] Specifically, the depth of the slot 3 is 8 mm, and the thickness of the pad 2 is 18 mm, so that after the pad 2 is installed, a 10 mm protrusion can be formed, so that a 10 mm heat dissipation channel can be formed between the copper bar and the core pull plate. The length and width of the slot 3 are 80 mm × 8.5 mm. The length and width of the pad 2 are 79 mm × 8 mm.

[0026] In order to achieve the insulation effect, the pad 2 is a DMC insulating pad. The top surface of the pad 2 is provided with a chamfer, and the periphery needs to be deburred. The entire pull plate 1 needs to be treated with a spray after surface pickling and phosphating.

[0027] In order to realize the installation of the clamps on both sides, two latches 4 need to be provided. The pull plate 1 is provided with a latch hole 5 , a boss 41 is provided at the bottom of the latch 4 , and the latch 4 cooperates with the boss 41 and the latch hole 5 .

[0028] In order to ensure the installation stability of the cushion block 2, the side wall of the cushion block 2 is provided with a positioning protrusion 21, and the positioning protrusion 21 is triangular and hollow. The side of the slot 3 is provided with a protrusion slide 31, and the side wall of the protrusion slide 31 is provided with a positioning groove 32, and the positioning protrusion 21 is placed in the positioning groove 32. The outer side of the positioning protrusion 21 is provided with an arc-shaped protrusion 22, and the arc-shaped protrusion 22 is against the positioning groove 32. During the insertion of the cushion block 2, the positioning protrusion 21 can be stuck in the positioning groove 32 after slight deformation, so as to achieve a limiting effect.

[0029] Working principle: When in use, the spacer 2 will be placed between the copper bar and the core pull plate of the dry-type transformer on both sides, thereby replacing the poor supporting structure of the three people such as the partition, ensuring that there is a certain heat dissipation space between the two and increasing the heat dissipation efficiency of the two.
