Two cooling fans 301 are installed at the rear ends of the three temperature control chambers 3, and side air inlets 305 are provided on both sides of the three temperature control chambers 3;

[0030] The auxiliary control box 304 is installed above the middle temperature control chamber 3. The second single-chip microcomputer chip 6 and the second wireless data transmission module 7 are installed inside the auxiliary control box 304. The second single-chip microcomputer chip 6 is bidirectionally wirelessly connected to the first wireless data transmission module 5 on the first single-chip microcomputer chip 4 through the second wireless data transmission module 7.

[0031] The temperature sensor 303 is installed at the middle position of the front ends of the three temperature control chambers 3 , and the detection end of the temperature sensor 303 penetrates and extends to the interior of the temperature control chamber 3 .

[0032] See also Figure 4 The output ends of the manual-automatic conversion switch 105 and the fan switch 106 are both electrically connected to the input end of the first single-chip microcomputer chip 4, and the manual-automatic conversion switch 105 can be used to switch the manual and automatic control states of the control device.

[0033] Please refer to the figure, the output end of the temperature sensor 303 is electrically connected to the input end of the second single-chip microcomputer chip 6, and the output end of the first single-chip microcomputer chip 4 is electrically connected to the input end of the display screen 104. If it is in manual control state, a signal can be sent to the first single-chip microcomputer chip 4 through the fan switch 106, and the first single-chip microcomputer chip 4 and the second single-chip microcomputer chip 6 interact wirelessly to further control the operation of the cooling fan 301 corresponding to the fan switch 106. During control, because the temperature sensor 303 can feed back the independent temperature information of the three chambers to the second single-chip microcomputer chip 6, the wireless interaction between the second single-chip microcomputer chip 6 and the first single-chip microcomputer chip 4 can further feed back the temperature information to the display screen 104 of the main controller 1, so as to facilitate personnel to autonomously turn on the cooling fan 301 at the corresponding position for heat dissipation according to the temperature state of different positions of the transformer.

[0034] Please refer to the figure. The output end of the second wireless data transmission module 7 is electrically connected to the input end of the heat dissipation fan 301 through the frequency converter 8. When it is in the automatic control state, the temperature sensor 303 feeds back the independent temperature information of the three chambers to the second single-chip microcomputer chip 6. If the temperature information of one or more chambers reaches the first threshold, the second single-chip microcomputer chip 6 controls the operation of a heat dissipation fan 301 in the corresponding chamber through the frequency converter 8, and gradually increases the output power of the heat dissipation fan 301 according to the temperature change from low to high within the threshold range. When the temperature information of one or more chambers reaches the second threshold, the second single-chip microcomputer chip 6 further controls the operation of another heat dissipation fan 301 in the corresponding chamber through the frequency converter 8 to increase the heat dissipation rate to ensure the operating temperature of the transformer.

[0035] Please refer to the figure, one side of the inspection door 101 is rotatably connected to the main controller 1 through a hinge 102, and the other side of the inspection door 101 is locked and connected to the main controller 1 through a pop-up lock 103.

Non-woven fabric layers are arranged on the inner walls of the first dust-proof net 302 and the second dust-proof net 306. The first dust-proof net 302 and the second dust-proof net 306 cooperate with the non-woven fabric layer to better isolate the dust in the air and prevent it from entering the heat dissipation fan 301 and the temperature control chamber 3. The heat dissipation fan 301 is an exhaust structure. When running, fresh air can be introduced from the side air inlet 305 and discharged to the outside, thereby discharging the heat at the corresponding position of the transformer.

[0037] Working principle: The control device is a manual-automatic integrated structure. When working, the manual and automatic control states of the control device can be switched through the manual-automatic conversion switch 105. When switched to the manual control state, a signal can be sent to the first single-chip microcomputer chip 4 through the fan switch 106, and the first single-chip microcomputer chip 4 and the second single-chip microcomputer chip 6 interact wirelessly to further control the operation of the cooling fan 301 corresponding to the fan switch 106. During control, because the temperature sensor 303 can feed back the independent temperature information of the three chambers to the second single-chip microcomputer chip 6, the second single-chip microcomputer chip 6 and the first single-chip microcomputer chip 4 can further feed back the temperature information to the display screen 104 of the main controller 1 through wireless interaction, so as to facilitate personnel to adjust the temperature according to the different positions of the transformer. In the temperature state, the cooling fan 301 at the corresponding position is automatically turned on for heat dissipation. When it is switched to the automatic control state, the temperature sensor 303 feeds back the independent temperature information of the three chambers to the second single-chip microcomputer chip 6. If the temperature information of one or more chambers reaches the first threshold, the second single-chip microcomputer chip 6 controls the operation of a cooling fan 301 in the corresponding chamber through the inverter 8, and gradually increases the output power of the cooling fan 301 according to the temperature change from low to high within the threshold range. When the temperature information of one or more chambers reaches the second threshold, the second single-chip microcomputer chip 6 further controls the operation of another cooling fan 301 in the corresponding chamber through the inverter 8 to increase the heat dissipation rate to ensure the operating temperature of the transformer.
