[0002] Gas-insulated metal-enclosed switchgear is a metal-enclosed switchgear and control equipment that uses gas at a pressure higher than atmospheric pressure as the insulating medium in at least one part. GIS (GAS INSULATED SWITCHGEAR) is the English abbreviation for gas-insulated fully enclosed switchgear. GIS consists of circuit breakers, disconnectors, earthing switches, transformers, lightning arresters, busbars, connectors and outgoing terminals. These devices or components are all enclosed in a metal grounded casing, which is filled with SF6 insulating gas at a certain pressure, so it is also called SF6 fully enclosed switchgear. Gas-insulated metal-enclosed switchgear. When a gas-insulated metal-enclosed switch fails, it is sporadic and short-lived, and the duration of the failure is short. It is not easy for personnel to observe and detect. It is urgent to simulate various partial discharge signals when the gas-insulated metal-enclosed switch fails through a test device, and record and analyze them through a detection device. After searching, application number 202223268246.6 discloses a gas-insulated metal-enclosed switch partial discharge live detection simulation device, including a base, a gas-insulated metal-enclosed switch device body is installed in the middle of the upper side of the base, and guide rods and screw rods are respectively installed on the upper sides of both ends of the base through support seats, a first slide is arranged on the upper side of the screw rod for sliding thread, a second slide is arranged on the guide rod for sliding, and a protective cover is installed on the upper side of the first slide and the second slide through a vertical pole, and a partial discharge tester is installed on the inner side of the protective cover.
