  • What is gaz 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.

  • insulating gas Circuit Breakers - Construction Working Principle

    In Sulfr hexafluoride circuit breakers, sulphur hexafluoride (sf6 gas) gas is used as the arc quenching medium. The sf 6 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 gas and an arc is struck between them.
