It should be noted that, the wind speed sensor can detect the wind speed introduced into the casing 101, the temperature detected by the temperature sensor exceeds the first temperature threshold but is not high, so that the fan 311 is in a rotating state but is not high in rotation speed, the heat dissipation requirement is not large at this moment, the ventilation assembly 3 controls the deflection angle of the ventilation fan blade 303 to be between 30 and 60 degrees, at this moment, the opening at the ventilation fan blade 303 and the air inlet is smaller, the wind speed introduced into the casing 101 is lower, at this moment, the controller controls the air cylinder 213 to shrink inwards, so that the heat dissipation plates 202 can be driven to move away from each other, the distance between the heat dissipation plates 202 is maximized, so that the heat on the transformer body 102 and the heat dissipation plates 202 can be blown out by flowing air under the blowing action of the fan 311, thus the basic wind blowing heat dissipation operation can be realized, and as the transformer body 102 works, although a part of heat can be taken away through the cooperation of the heat dissipation component 2 and the ventilation component 3, the heat generated by the transformer body 102 is gradually increased, namely the temperature value detected by the temperature sensor is gradually increased, and the rotating speed of the fan 311 is controlled by the controller to be increased along with the increase of the temperature at the moment, so that the air quantity led into the transformer body 102 in unit time can be improved, the transformer body 102 is driven by fast flowing air to realize the operation of direct blowing and air blowing to facilitate heat dissipation, in the process, the air speed is smaller, the adjustment of the interval between the heat dissipation plates 202 has no influence on the heat dissipation performance, the distance between the heat dissipation plates 202 on the heat dissipation component 2 is always in the maximum state, the air contact area is improved, the heat taken away when the air flows is improved, the accumulation of the heat inside the transformer body 102 can be effectively reduced, the heat dissipation effect is improved, when the temperature value detected by the temperature sensor is reduced or increased to a smaller extent than the standard range, the heat dissipation is faster and the efficiency is higher, the purpose of heat dissipation and temperature reduction is achieved, and the working states of the ventilation assembly 3 and the heat dissipation assembly 2 are kept unchanged.
