6 Decomposition and Contamination • Reactive decomposition byproducts form when SF 6 is exposed to: 1. spark discharges, 2. partial discharges, 3. switching arcs, and 4. failure arcing • Decomposition byproducts can take the form of gas or powders • Other types of contaminants can include moisture and air (from handling or leakage),
the 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 association based in France.

Nov 01, 20071. Introduction. Sulfur hexafluoride (SF 6), molecular weight 146.07, is a colorless, odorless, nonflammable and heavy gas with excellent electrical characteristics that make it applicable for some special uses in the electrical/electronic equipments, industrial processes, scientific fields and commercial products , , .Due to its low toxicity, thermal stability and high breakdown strength
Incompatibilities: Avoid leakage of a liquefied gas such as SF6 onto water or contact hot reactive metals. Hazardous Decomposition Products: Thermal and electrical arc decomposition products: GASES – fluorides or sulfur (particularly sulfured fluoride, a convulsing, and thionyl fluoride and thionyl tetrafluoride, pulmonary irritants).
Decomposition products of SF6 gas may be in the form of gases or powders. Solid decomposition products are normally metal flourides in the form of white, tan, or gray powder. Solid decomposition products in the form of powders are very fine and may not always be detected by the human eye, especially when airborne.
AVANTEC in their factory, removing the decomposition products. Generally, this paper describes the treatment and the recycling of a used gas. 2/ Introduction Fig.1. Typical 245 kV dead tank circuit breakers using SF6 gas as Fig. 2. Typical Gas Insulated Substation (GIS) 245 kV using SF6 gas as internal insulation and interrupting medium.
Abstract: The increasing application of SF6 as an insulating gas has led to many studies on SF6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, SF6 decomposes to a wide variety of chemically active products which possess completely different properties from SF6.
SF6 gas is pumped using an oil-less compressor system to prevent oil contamination of the gas. Gas liquefaction is achieved by pressurization thereby eliminating the need for refrigeration equipment. Gas recovery over 99% is achievable. Baron SF6 gas systems utilize replaceable filters to remove particulate, moisture and decomposition productsGet Price

6 decomposition products and membranes for the removal of inert gas. INTRODUCTION Sulfur hexafluoride (SF 6) is a physically stable, non-toxic and inert gas with high dielectric strength and thermal stability. It is generally used in electrical equipment for power transmission
Sep 20, 2019It likely forms via an electrically induced decomposition reaction of SF 6: 2 SF 6(g) → S 2 F 10(g) + F 2(g) S 2 F 10 has a toxicity four times that of phosgene, COCl 2! In WWII, gaseous S 2 F 10 was considered a chemical warfare pulmonary agent. Its toxicity emanates from the disproportionation reaction: S 2 F 10(g) → SF 6(g) + SF 4(g)
