sf6 gas Decomposition Reclamation

sf 6 Decomposition Reclamation Abstract: The increasing application of gaz sf6 as an insulating gas has led to many studies on sf6 gas decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, Sulfr hexafluoride decomposes to a wide variety of chemically active products which possess completely different properties from Sulfr hexafluoride.

The Sulfr hexafluoride Decomposition Mechanism: Background and Significance

Jan 24, 2017 · Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (gaz sf6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of Sulfr hexafluoride to SOF2, SO2F2 and SO2 and other characteristic component gases.

Myth About sf6 gas Gas In Electrical Equipment

Where is gaz sf6 used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is sf 6 a health hazard? Pure gaz sf6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is insulating gas harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of sf 6 used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).
