[0022] The breathable protection component 22 includes: an electric lifting rod 226, a pushing plate 227, a side guard plate 221, a first ventilation long slot group 222, a second ventilation long slot group 224 and a built-in guard plate 223.

The second ventilation long slot group 224 is opened at the front and rear ends of the built-in guard plate 223, and the first ventilation long slot group 222 is opened at the front and rear ends of the side guard plate 221.

[0023] The specific implementation method is as follows: when using the utility model, the refrigeration water tank 216 is started first. After the refrigeration water tank 216 is started, water is poured into the refrigeration water tank 216 through the water inlet pipe 214 opened at the upper end. After the refrigeration water tank 216 is filled with water, the refrigeration water tank 216 can refrigerate the water inside. After the refrigeration inside the refrigeration water tank 216 is refrigerated, the blower 211 is started. After the blower 211 is started, the gas is transmitted to the inside of the cooling spiral pipe 212 through the exhaust pipe arranged at the rear end. When the gas enters the cooling spiral pipe 212, the gas can be cooled by the lower internal temperature. After the gas inside the cooling spiral pipe 212 completes the cooling work, it can be collected and discharged into the exhaust two-way pipe 218 through the air inlet pipe 215, and then discharged into the inside of the transformer outer cover 24 through the two sets of exhaust pipes 219 installed at the rear end of the exhaust two-way pipe 218. The transformer body 23 installed inside the transformer outer cover 24 is cooled by dry air. Temperature treatment, when the inside of the transformer body 23 needs to be ventilated for heat dissipation and cooling, the first ventilation long slot group 222 and the second ventilation long slot group 224 can be staggered with each other. After the two groups of first ventilation long slot groups 222 and second ventilation long slot groups 224 are connected, ventilation work can be carried out. When the first ventilation long slot group 222 and the second ventilation long slot group 224 are staggered with each other to form a closed space, the gas inside the transformer outer cover shell 24 cannot circulate, which can be used when the transformer body 23 stops working. The transformer outer cover shell 24 forms an avoidance space when it stops using, which effectively avoids the problem of dust entering and causing a lot of dust accumulation inside the transformer outer cover shell 24, which makes the internal cleaning more difficult. The device works through simple and convenient air cooling and cooling treatment, while quickly reducing the internal temperature of the transformer outer cover shell 24, it improves the internal drying performance of the transformer outer cover shell 24, and avoids the problem of accelerated equipment damage caused by a lot of water vapor inside the transformer outer cover shell 24.
[0024] Working principle of the utility model: when using the utility model, first start the refrigeration water tank 216. After the refrigeration water tank 216 is started, water is poured into the refrigeration water tank 216 through the water inlet pipe 214 opened at the upper end. After the refrigeration water tank 216 is filled with water, the refrigeration water tank 216 can refrigerate the water inside. After the refrigeration inside the refrigeration water tank 216 is completed, the blower 211 is started. After the blower 211 is started, the gas is transmitted to the inside of the cooling spiral pipe 212 through the exhaust pipe arranged at the rear end. When the gas enters the cooling spiral pipe 212, the gas can be cooled by the lower internal temperature. After the gas inside the cooling spiral pipe 212 completes the cooling work, it can be collected and discharged into the exhaust two-way pipe 218 through the air inlet pipe 215, and then discharged to the transformer cover through the two sets of exhaust pipes 219 installed at the rear end of the exhaust two-way pipe 218. The inside of the transformer outer cover shell 24 performs a dry air cooling treatment on the transformer body 23 installed inside the transformer outer cover shell 24. When the inside of the transformer body 23 needs to be ventilated for heat dissipation and cooling, the first ventilation long slot group 222 and the second ventilation long slot group 224 can be staggered with each other. After the two groups of first ventilation long slot groups 222 and second ventilation long slot groups 224 are connected, ventilation can be carried out. When the first ventilation long slot group 222 and the second ventilation long slot group 224 are staggered with each other to form a closed space, the gas inside the transformer outer cover shell 24 cannot circulate, which can be used when the transformer body 23 stops working. The transformer outer cover shell 24 forms an avoidance space when it stops being used, which effectively avoids the problem of dust entering and causing a lot of dust accumulation inside the transformer outer cover shell 24, which makes the internal cleaning more difficult.
