Sustainable Alternatives to Sulfr hexafluoride Gas within MV and HV

Aug 03, 2018 · Be part of the chalenge: propose a solution! The challenge is aimed at finding alternative solutions to the use of insulating gas gas as an insulating and/or interrupting medium within MV and HV equipment. Sulfur Hexafluoride (sf 6) gas is largely used as a dielectric and insulating material in the transmission and distribution equipment. Unfortunately, gaz sf6 is also an extremely potent greenhouse gas with

Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any S 2 F 10 (which is highly toxic) and then scrubbing the product with NaOH to destroy remaining SF 4.

Due to their relatively high boiling point, they should be used as a mixture with buffering gases with low boiling points. Based on these four characteristics, perfluorinated ketones (C 5 F 10 O and C 6 F 12 O) and fluoronitrile (C 4 F 7 N) could partially substitute SF 6 in some electrical equipment.

According to these characteristics, CF 3 I has been a potential alternative to SF 6 as a new insulating gas. Due to its high boiling point of −22.5 °C and the formation of I 2 in pure CF 3 I, CF 3 I should be mixed with other gases with low boiling point, such as N 2, CO 2, O 2, air, CF 4, Ar, Xe, and He.

Why the EU should ban sf6 gas

What Is insulating gas? 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 sf 6 Emissions Difficult? Do Better Solutions Exist?Conclusiongaz sf6 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 sf6 gasproduced (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.
