  • What is SF6 Circuit Breaker? Construction, Working Principle

    A circuit breaker in which SF 6 under pressure gas is used to extinguish the arc is called SF 6 circuit breaker. SF 6 (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties which have proved its superiority over other arc quenching mediums such as oil or air. The SF 6 circuit breaker is mainly divided into three types.

  • SF6 Circuit Breakers - Construction, Types and Working

    SF6 can be heated without decomposition to 500°C in the absence of catalytic metals. SF6 is non-flammable and hydrogen, chlorine, and oxygen have no action on it. SF6 is insoluble in water and is not attacked by acids. Toxicity of arc products. Toxic decomposition products are formed when SF6 gas is subjected to an electric arc. The decomposition products are metal fluorides and form a white or tan powder.
