Abstract

The invention discloses a sulfur hexafluoride mixed gas purification recovery gas distribution gas supplementary device. The sulfur hexafluoride mixed gas purification recovery gas distribution gas supplementary device comprises a mixed gas recovery system and a gas distribution gas supplementary system; the mixed gas recovery system comprises a first recovery gas pipe, a second recovery gas pipe,a third recovery gas pipe, a recovery port, and a first buffer tank; the gas distribution gas supplementary system comprises a gas distribution main pipe and a gas supplementary pipe. The sulfur hexafluoride mixed gas purification recovery gas distribution gas supplementary device is capable of avoiding defects that conventional SF6 mixed treatment method is complex, consumed time is long, and cost is high. The sulfur hexafluoride mixed gas purification recovery gas distribution gas supplementary device can be used for high voltage switchgears, and especially can be used for heavy maintenanceor disintegration overhaul of SF6 mixed gas insulation high voltage switchgears.

Description

technical field [0001] The invention belongs to the technical field of overhauling or dismantling overhaul of sulfur hexafluoride mixed gas insulated high-voltage switchgear, and in particular relates to a sulfur hexafluoride mixed gas purification and recovery gas distribution device and an operating method thereof. Background technique [0002] Gas Insulated Switchgear (GIS) is widely used in power systems due to its small footprint, high reliability, strong safety, and low maintenance workload. In recent years, mixed gas (SF 6 / N 2 or SF 6 / CF 4 ) GIS as an insulating gas has gradually been applied in power engineering. [0003] Filling SF 6 For the GIS bus of the mixed gas, after the overhaul or type test of the GIS, the mixed gas in the GIS needs to be recovered. When recovering gas, it is necessary to use a measuring instrument to measure the concentration and humidity of the mixed gas. If it is found that the concentration of the mixed gas deviates from the conc...
