With the development of the economy, electrification runs through almost all fields of the national economy, and the application of power transformers is becoming more and more extensive. The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, secondary coil and iron core. (magnetic core), the main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage regulation (magnetic saturation transformer), etc. During the operation of the transformer, a large amount of heat will be generated, which will cause the temperature of the transformer to rise and cause frequent trips. If it is operated at a high temperature for a long time, it is easy to reduce the insulation performance, increase the power loss, and cause the transformer to burn out in severe cases, jeopardizing the security of the power supply network.

A common transformer cooling method is to install a cooling fan at the bottom of the transformer cabinet, and dissipate heat through the cooling window at the bottom. Due to the low density of hot air generated during operation, a large amount of hot air accumulates on the top of the transformer cabinet and cannot be discharged, and the cooling effect is not obvious. In addition, during the long-term operation of this heat dissipation method, the accumulation of dust in the device may easily lead to blockage of the fan, and the heat dissipation effect is not good.
