SF6 gas conveying device of high-voltage circuit breaker

The invention discloses an SF6 gas conveying device of a high-voltage circuit breaker. When the SF6 gas conveying device of the high-voltage circuit breaker is in use, sulfur hexafluoride gas (SF6 gas) is stored in a gas storage tank, the SF6 gas is output into a conveying pipe through a gas outlet nozzle of the gas storage tank, the SF6 gas is transferred and output into the high-voltage circuitbreaker through the conveying pipe, and the high-voltage circuit breaker is an SF6 gas circuit breaker; before gas conveying, the gas pump blows gas into the conveying pipe, the gas flow direction isfrom the two sides to the middle, air in the conveying pipe enters the drying tank, and the drying agent dries the air; in conclusion, the drying work in the conveying pipe can be achieved, and the gas pump is turned off after drying is finished; at the moment, the dried conveying pipe can be used for transferring the SF6 gas into the high-voltage circuit breaker, moisture can be prevented from entering the high-voltage ci
