High-power sulfur hexafluoride recovery recharging device

Abstract

The invention provides a high-power sulfur hexafluoride recovery recharging device. A sulfur hexafluoride electric device is connected with a main pipe of a busbar sequentially through a first hand valve, an adsorption tank, a first electric valve, a booster pump, a compressor, a second electric valve, a third electric valve, a first fan heat exchanger, a flooded shell-and-tube heat exchanger and a second hand valve, and a steel cylinder placed on an electronic balance is communicated with each branch pipe of the busbar. The connecting position of the sulfur hexafluoride electric device and the first hand valve is connected with a vacuum pump sequentially through a fourth hand valve and a digital display vacuum gauge and connected with the main pipe of the busbar sequentially through the second fan heat exchanger and a third hand valve. The connecting position of the first hand valve and the adsorption tank is connected with the connecting position of the third electric valve and the first fan heat exchanger through a pipe provided with a fifth electric valve. The connecting position of the adsorption tank and the first electric valve is connected with an inlet of the compressor through a pipe provided with an electric adjusting valve. The connecting position of the second electric valve and the third electric valve is connected with the main pipe of the busbar through a pipe provided with a fourth electric valve.

Description

technical field [0001] The invention relates to a high-power sulfur hexafluoride recovery and recharging device, which belongs to the technical field of electrical equipment gas recovery. Background technique [0002] Sulfur hexafluoride can exist in the air for 3,000 years, and its greenhouse effect is 23,900 times that of CO2. It is one of the six gases prohibited by the Jingdong Protocol. The State Grid Corporation has committed itself to environmental protection obligations to the society, requiring the timely recovery of sulfur hexafluoride gas in the equipment and recycling after purification to prevent the emission of SF6 greenhouse gas into the atmosphere. GB / T8905-2012 "Guidelines for Gas Management and Detection in Sulfur Hexafluoride Electrical Equipment" stipulates that when the equipment is disassembled, all sulfur hexafluoride gas should be recovered through the gas recovery device. [0003] At present, most of the sulfur hexafluoride gas recovery and refill d...

AI Technical Summary

Problems solved by technology

At present, the recycling speed of sulfur hexafluoride recovery and recharging devices used at home and abroad cannot meet the requirements of the construction period for the installation and maintenance of GIS, HGIS and other equipment with a large amount of gas that are widely used in the current power grid.
