Problems solved by technology

Sulfur hexafluoride gas needs to be extracted and charged before and after GIS troubleshooting, and the time for extracting and filling sulfur hexafluoride gas is sometimes longer than the maintenance time, which seriously affects the electricity consumption of residents
[0004] At present, the sulfur hexafluoride recovery device, vacuum pump, vacuum gauge, and sulfur hexafluoride storage device for extracting and filling sulfur hexafluoride gas are directly connected to the GIS through ordinary pipelines. When pumping sulfur hexafluoride gas → vacuum → In the process of measuring vacuum degree → filling sulfur hexafluoride gas, it is necessary to switch the connected devices frequently, which wastes a lot of time; in addition, due to the high requirements on sealing during the working process, good sealing needs to be re-sealed every time switching devices , which further increases the time to switch devices and has a high chance of poor sealing

Abstract

The invention discloses a system for pumping and inflating SF6 for a gas insulated switchgear (GIS), comprising an SF6 recovery device, a vacuum pump, an SF6 storage device, a vacuum gauge and a connection pipeline, wherein the connection pipeline is combination pipes with four pipes which are communicated with each other, a moveable connector matched to a connection device is respectively on each of four ports of the connection pipeline, any pipe of the combination pipes can individually be opened or closed, three ports of the combination pipes are respectively connected with a GIS main body, the SF6 recovery device and the vacuum pump, and the other port is respectively connected with the vacuum gauge and the SF6 storage device in order. The system for pumping and inflating SF6 can greatly save time for pumping and inflating SF6 for the GIS, and has good internal pressure endurance and sealing reliability. In addition, the system for pumping and inflating SF6 has versatility.

Description

technical field [0001] The invention relates to a system for extracting and charging sulfur hexafluoride gas for GIS. Background technique [0002] GIS (GAS INSULATED SWITCHGEAR) is the abbreviation of gas insulated fully enclosed combined electrical appliances. It is composed of circuit breaker, isolating switch, grounding switch, transformer, lightning arrester, busbar, connector and outlet terminal, etc. All these parts are enclosed in a metal grounding shell, and the inside is filled with a certain pressure of sulfur hexafluoride insulation. Gas, also known as sulfur hexafluoride fully enclosed combined electrical appliances. [0003] GIS equipment has been widely used all over the world since it was put into practical use in the 1960s. GIS has a compact structure, small footprint, high reliability, and strong safety, and is widely used in high-voltage, ultra-high voltage, and ultra-high voltage fields; however, GIS also has problems such as sulfur hexafluoride gas lea...
