The decomposition products of sulfur hexafluoride (gaz sf6

From the environmental and health points of view, it is necessary to mitigate and control the emissions of the decomposition products from SF 6 destruction processes because most of them (e.g. S 2 F 10, SF 4 and HF) are highly reactive, corrosive and toxic, and few of them are also potent GHGs. This article aimed to introduce the fully fluorinated gas in industrial/commercial uses, and its toxic decomposition products in their environmental and health hazards, occupational exposure limits

The gaz sf6 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 (insulating gas) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of gaz sf6 to SOF2, SO2F2 and SO2 and other characteristic component gases. The decomposition phenomenon would greatly reduce the

Why the EU should ban sf6 gas

What Is sf 6? and How Is It used?Is Sulfr hexafluoride A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of sf6 gas Emissions Difficult? Do Better Solutions Exist?ConclusionSulfr hexafluoride is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all Sulfr hexafluorideproduced (Powell, 2002: 6). Within the electrical industry Sulfr hexafluorideis used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.
