Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Embodiment 1, by Figure 1-Figure 3The utility model includes a shell 1, the lower end of the shell 1 is symmetrically connected to a support leg 2, a high-voltage bushing 3 is installed on the upper end of the shell 1, a low-voltage bushing 4 is installed on one side of the high-voltage bushing 3, a winding coil mechanism 5 is provided inside the shell 1, the front and rear ends of the shell 1 are connected to heat dissipation fins 6, the left and right ends of the shell 1 are connected to square tubes 7, and heat dissipation ports 8 are opened around the upper part of the shell 1, and a dustproof net 9 is provided inside the heat dissipation port 8;

[0022] A cooling fan 10 is installed inside the square tube 7, and a wind collecting cover 11 is connected to one side of the cooling fan 10;

[0023] An inner shell 12 is provided inside the shell 1, a cavity 13 is formed between the inner shell 12 and the shell 1, an air supply pipe 14 is installed inside the cavity 13, the air supply pipe 14 is spirally arranged, and the air supply pipe 14 is connected to the air collecting cover 11 through a connecting pipe 15;

[0024] The inner side walls of the inner shell 12 are connected with a blowing pipe 16, which is connected to the air supply pipe 14. The inner bottom wall of the inner shell 12 is evenly provided with bottom holes 17, which are connected to the air supply pipe 14.

[0025] The inner wall of the square tube 7 is connected with a block 18, a filter screen 19 is provided on one side of the block 18, a square ring 20 is movably provided on one side of the filter screen 19, and the square ring 20 is connected to the block 18 by passing through the filter screen 19 through a screw 21;

[0026] After long-term use, the square ring 20 can be taken out of the square tube 7 by loosening the disassembly screws 21, and then the filter 19 can be taken out for cleaning or replacement. Then, the square ring 20 and the block 18 are fixed by the screws 21 to limit the installation of the filter 19.

[0027] The blowing pipe 16 is arranged in a Y-shaped structure, which can increase the number of air outlets and accelerate the cooling effect of blowing.

[0028] Working principle: When working, the transformer generates high temperature, and air is blown into the shell 1 through the cooling fans 10 on both sides. The air is filtered by the filter 19 and gathered by the wind collecting cover 11. Then the air enters the air supply pipe 14 inside the cavity 13 through the connecting pipe 15. The air supply pipe 14 discharges the air through the blowing pipes 16 on both sides of the inner shell 12. At the same time, the blowing pipe 16 also discharges the air from the bottom hole 17 at the bottom of the inner shell 12. In this way, the wind blows and dissipates the heat to the internal components of the shell 1 from both sides and the bottom, and the heat moves upward and then is discharged from the shell 1 from the heat dissipation port 8. In addition, the heat dissipation fins 6 at the front and rear ends of the shell 1 work together to transfer the internal heat to the outside, so that the heat dissipation effect of the transformer is good.
