The invention relates to a gas-insulted power transmission line and barrel detachable connecting structure. The gas-insulated power transmission line comprises a detachable barrel and a detachable center conductor arranged in the barrel; the barrel comprises a first barrel, a second barrel and a sliding sleeve connected between the first barrel and the second barrel; one end of the sliding sleeveis inserted into the first barrel in a sliding sealing way, and the other end is connected with the second barrel through adaptive flanges in pair; a barrel flange is arranged at one end, inserted with the sliding sleeve, of the first barrel; and a connecting rod for maintaining the space between the adaptive flange and the barrel flange is arranged between the adaptive flange and the barrel flange. The connecting rod can maintain the space between the adaptive flange and the barrel flange; the connecting rod can guarantee the structure stabilization between the sliding sleeve and the first barrel; the barrel is dismounted through the sliding sleeve, an operation of arranging a corrugated pipe structure on the barrel is cancelled, the barrel structure is simplified, and the cost of the gas-insulated power transmission line is reduced.
Description
technical field [0001] The invention relates to a gas insulated power transmission line and a detachable connection structure of a cylinder body. Background technique [0002] Gas insulated transmission lines (GIL) have the advantages of high reliability, strong transmission capacity, low loss, safety and environmental protection, etc., and are widely used in power engineering. The gas-insulated transmission line is a kind of transmission equipment with a closed shell and long laying lines. When a fault occurs during operation or regular maintenance, the shell needs to be opened to observe the internal conditions. The special structure of the gas-insulated transmission line makes it difficult to disassemble. Therefore, A detachable housing is required for easy maintenance. [0003] The authorized announcement number is CN202167762U, and the authorized announcement date is 2012.03.14. The Chinese utility model patent discloses a busbar assembly for ultra-high voltage enginee...
