2017-1-24Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and other characteristic component gases. The decompositionCited by: 1

The liquefaction problem of SF6 is also solved by the mixture of SF6/N2 (e.g., the liquefaction point of gas detection systems. detect the SF6 decomposition. Stone [27] used the ultrasonic

2016-2-11the decomposition products and concentrations formed under actual conditions can vary depending on the equipment used and the type of electrical discharge (CIGRE 1997). 1 CIGRE (the International Council on Large Electric Systems) is a permanent non-governmental and non profit-making international

2019-3-1A photoacoustic sensor system for the ppb-level CO detection of sulphur hexafluoride (SF 6) decomposition was developed by use of a 10 W fiber-amplified near-infrared (NIR) diode laser.A photoacoustic detection module with symmetrical construction was designed to allow a high power laser beam and a large gas flow.Cited by: 11

2007-11-1Sulfur hexafluoride (SF 6) is being widely used in a variety of industrial processes, commercial products and scientific fields due to its unique characteristics such as relatively low toxicity, extreme inertness and high dielectrics.However, the chemically stable gas is one of the most potent greenhouse gases (GHGs) thatCited by: 120

In this paper, we adopted the first-principles calculations to investigate the sensing properties of the GeP monolayer to four SF6 decomposition gas molecules (H2S, SO2, SO2F2 and SOF2).

However, detection tubes have poor accuracy because the concentration of decomposition products is determined by color changes, making these tubes unsuitable for on-line monitoring. 21 A gas-sensitivity sensor can be connected to the equipment to achieve online monitoring or portable detection. However, theCited by: 5
