[0002] In order to achieve the goal of "carbon peak and carbon neutrality" and adapt to the requirements of green and low-carbon life, the demand for large-capacity ultra-high voltage transformers is becoming more and more obvious. However, transformers installed in areas with inconvenient transportation need to be disassembled and transported and assembled on site. For example, the clamps on the core of a 1000kV disassembled transformer need to be disassembled and transported. The clamps are equipped with shielding plates and insulating parts. According to past experience, in order to prevent the shielding plates and insulating parts from being bumped and damaged during transportation, they need to be disassembled and transported separately.
[0003] When the core clamps of a 1000kV transformer are transported separately, the clamp shielding plates and the core clamps are exposed to the outside and are easily exposed to the residual moisture in the air, which causes them to get damp and rust, thus reducing the service life of the core clamps.

[0023] It should be noted that the inflation device 6 can only fill dry air or nitrogen into the fuel tank 1, so as to maintain the dry state of the air in the fuel tank 1 and prevent it from being damp.
