Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of

Sulfur hexafluoride circuit breaker - Wikipedia

An SF 6 circuit breaker rated 115 kV, 1200 A installed at a hydroelectric generating station. Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit.

The global gas insulated switchgear market for medium voltage is forecast to grow over 8% per annum through 2022. In certain markets, minimizing or eliminating SF 6 emissions is increasingly prioritized. However, currently even best practices are self-imposed and not widespread due to scant legal obligation on SF 6 emissions. Since switchgear typically has a lifetime of 40-50 years, it is critical to act now.

gaz sf6 gas as insulating and arc-quenching medium

Sep 20, 2011 · Sulphur hexafluoride gas (insulating gas) is employed as insulation in all parts of the installation, and in the circuit-breaker also for arc-quenching. gaz sf6 is an electronegative gas, its dielectric strength at atmospheric pressure is approximately three times that of air. It is incombustible, non-toxic, odourless, chemically inert with arc-quenching properties 3 to 4 times better than air at the same pressure.
