Problems solved by technology

When the equipment is inspected on site, if the detection gas is discharged randomly, it may hinder the personal safety of the inspectors and pollute the atmospheric environment at the same time.
Currently used SF 6 The gas composition detection device lacks consideration for personal safety and environmental protection. It only connects an exhaust pipe several meters long to the downwind place to directly discharge the detection gas. Due to the fast outdoor air circulation, it may cause personal injury, and the SF 6 Gas emissions are not conducive to environmental protection

Abstract

The invention brings forward an environment-friendly type real-time detection apparatus for analysis of components in sulfur hexafluoride (SF6) gas and a method used therein. The apparatus comprises a real-time detection module and an environment-friendly recovery module. The method comprises the following steps: analyzing components in SF6 gas, absorbing and removing impurities in SF6 gas output after composition analysis and recovering SF6 gas. The environment-friendly type real-time detection apparatus and the method provided in the invention can carry out real-time detection of gas components which can reflect the operation state of gas insulation equipment, enable environment-friendly recovery of detection gas to be realized and provide effective guarantee for reliable operation of electric power equipment and safety protection of detection personnel.

Description

technical field [0001] The invention belongs to the field of gas detection, in particular to a method for analyzing sulfur hexafluoride (hereinafter referred to as SF) in gas-insulated equipment in power systems. 6 ) Gas component detection device and method thereof. Background technique [0002] SF 6 Gas has excellent insulation and arc extinguishing properties, and is widely used in gas-insulated equipment in power systems such as GIS, circuit breakers, and transformers. SF 6 The chemical properties of the gas are relatively stable. Under normal operating conditions, the SF of the gas-insulated equipment 6 Gas decomposition products are less. Due to the long-term charged operation of the equipment or under the action of discharge, the SF 6 The gas is easily decomposed to produce SF 4 , SF 2 and S 2 f 2 And many other low fluoride sulfides. If SF 6 No impurities, as the temperature decreases, the decomposition gas can be quickly recombined and reduced to SF 6 . ...
