Middle-high voltage rotary transmission conductive gas insulation equipment

The utility model discloses a middle-high voltage rotation transmission conductive gas insulation device, comprising a housing provided with a sealing cavity; the conductive circular ring assembly is arranged in the sealing cavity; and the inflation valve is arranged on the shell, and the inflation valve is communicated with the sealing cavity. The shell is provided with the sealing cavity for containing the conductive circular ring assembly, and meanwhile the shell is provided with the inflation valve communicated with the sealing cavity, so that gas can be inflated into the sealing cavity through the inflation valve, and then the air pressure in the sealing cavity is increased. According to the Pahen's law, the gas pressure and the breakdown voltage are positively correlated within a certain range, that is, the threshold value of the breakdown voltage can be increased by the high gas pressure, the occurrence of electric breakdown conditions is reduced, short circuit between transmission channels in the cond
