  • Sulfur hexafluoride - Wikipedia

    From Wikipedia, the free encyclopedia (Redirected from Sf6) Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), 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.

  • SF6 Circuit Breaker: What Are They? (Types and Operation

    Oct 23, 2020 · An SF6 circuit breaker is a type of circuit breaker in which sulphur hexafluoride gas or SF 6 gas is used as the arc quinching medium, known as an SF6 circuit breaker. SF 6 gas has excellent insulating property and it has a high electronegativity. Due to high electronegativity, it has a high affinity for absorbing free electrons.

    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 sulphur hexafluoride gas (SF6) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride (SF6) gas and an arc is struck between them. The gas captures the conducting free electrons in the arc to form relatively immobile negative ions.
