[0002] At present, with the continuous development of society, the electric power industry has been booming. In the process of power transmission, transformers are often needed. Transformers are the most important component of switching power supplies, especially high-frequency transformers based on DC power supplies. The ratio of the number of turns of each winding coil of the high-frequency transformer determines the output voltage.
[0003] When the weather is hot, the transformer runs at high temperature for a long time, which will shorten the service life of the internal insulating cardboard, make the insulating cardboard brittle and easy to break, lose its due insulation effect, seriously age the winding insulation, accelerate the deterioration of the insulating oil, and affect the service life. In addition, running at high temperature for a long time can easily cause internal combustibles to burn, leading to safety hazards. The existing fastening heat dissipation structure of the high-frequency transformer is not convenient for protecting the high-frequency transformer body, and it is not convenient for the high-frequency transformer to dissipate heat.
