Background
GIS (GAS insulated SWITCHGEAR) is the English abbreviation of the gas-insulated fully-enclosed combined electrical apparatus. GIS consists of a breaker, a disconnecting switch, a grounding switch, a mutual inductor, a lightning arrester, a bus, a connecting piece, an outgoing terminal and the like, all of which are enclosed in a metal grounding shell, and SF with a certain pressure is filled in the metal grounding shell 6 Insulating gases, also known as SF 6 A totally-enclosed combined electrical appliance. CGIS is the product of a combination of GIS technology and switchgear technology, also known as gas-filled switchgear, and has a cabinet housing containing three-phase high-voltage components in welded steel boxes at intervals, the boxes being filled with SF slightly above atmospheric pressure 6 The gas acts as an insulator.
The inflatable switch cabinet has good insulating property and environment adaptability, can be used in various severe environments, but has a price which is much higher than that of air-insulated switch cabinet equipment, is basically more than twice that of the air-insulated switch cabinet equipment, and has poor economical efficiency. On the other hand, in the existing inflatable switch cabinet equipment, when the middle cabinet needs to be dismantled, one side of the cabinet needs to be removedThe gas-filled switch cabinet is arranged, or bus sleeves on two sides in the cabinet need to be removed, so that the maintenance is very complicated, the power failure time is long, and the insulating gas in the gas-filled switch cabinet is generally SF 6 ，SF 6 Is a greenhouse gas, has a GWP value of 23500, is greatly destroyed to the environment, and can cause additional SF if more inflatable switch cabinets are involved when the intermediate cabinet is dismantled 6 Leakage can have adverse environmental effects.
The bus sleeve is connected with the main bus and the gas tank rear sealing plate through the bus connector, the volume of the gas-filled switch cabinet can be reduced, the middle cabinet can be directly pulled out and plugged, the influence on other gas-filled switch cabinets is avoided, when the bus connector is connected with the bus sleeve, the bus connector can push the bus sleeve, and after the bus connector is pushed for multiple times, looseness can exist on the bus sleeve and the gas tank rear sealing plate to influence the air tightness of the whole device due to the fact that the end part of the bus connector has higher rigidity.
