Abstract

The invention relates to a sealing method for gas-insulated all-closed combined electrical appliances. The sealing method for gas-insulated all-closed combined electrical appliances comprises the following steps: first, a first connecting layer and a second connecting layer are fixed on the surface of a combined electrical appliance, and the gas leaking through the gas leakage hole in the combinedelectrical appliance can be discharged through a connecting channel so as to prevent high-speed gas flow from hindering the fixation of the two connecting layers on the surface of the combined electrical appliance; then, one end of a ventilator is extended in from a second through hole and fixed through a fixture, and the problem that the ventilator and the fixture cannot be fixed is avoided because the leaked gas can still be discharged through the ventilator; and after the ventilator is fixed, the gas leakage hole of the combined electrical appliance can be sealed by sealing the ventilatorthrough a sealing element, without exhausting the gas. The gas leakage hole of the combined electrical appliance can be repaired online, and the maintenance cycle is shortened. Moreover, there is no need to cut off the power system, and the loss caused by power failure is avoided.

Description

technical field [0001] The invention relates to the technical field of insulating gas leakage repair equipment, in particular to a sealing method for a gas-insulated fully enclosed combined electrical appliance. Background technique [0002] With the vigorous development of the country's electric power industry, gas-insulated fully enclosed composite electronics are also developing rapidly. Gas-insulated fully enclosed combined electrical appliances are widely used in electrical equipment for their excellent insulation performance and arc extinguishing performance. When the existing gas-insulated fully-enclosed combined electrical appliances are used, gas leakage will occur in the gas chamber of the combined electrical appliance due to various factors, such as uneven flange surface, rust, seal ring failure and dislocation, tube wall trachoma and voids. welding etc. At present, the traditional maintenance method takes a long time for power outage and exhaust, and the mainte...
