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

    Oct 23, 2020Due to its low gaseous viscosity, SF6 gas can efficiently transfer heat by convection. So due to high dielectric strength and high cooling effect, SF 6 gas is approximately 100 times more effective arc quenching media than air.. Due to these unique properties of this gas, SF6 circuit breaker is used in a complete range of medium voltage and high voltage electrical power system.

  • SF6 Circuit Breakers - Construction Working Principle

    Sulphur Hexafluoride (SF6) circuit breaker: In SF6 circuit breakers, sulphur hexafluoride (SF6) gas is used as the arc quenching medium. The SF6 is an electro-negative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow of SF6 gas and an arc is struck between them.

  • Comparison Between Vacuum and SF6 Circuit Breaker

    Aug 29, 2018In 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.
