Manual sf6 vacuum process

Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas which is an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. SF 6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.

    Aug 29, 2018 · In an SF6 circuit-breaker, the current continues to flow after contact separation through the arc whose plasma consists of ionized SF6 gas. For, as long as it is burning, the arc is subjected to a constant flow of gas which extracts heat from it. The arc is extinguished at a current zero, when the heat is extracted by the falling current.

    The process is reversible, so that nearly all of the SF6 recombines after interruption. Thus, very little of the SF6 is "used up" during interruption, particularly for interruption of moderate (load) currents. SF6 dissociates during arcing into its atomic constituents, one sulfur atom and six fluorine atoms.
