  • What is Sulfr hexafluoride Circuit Breaker? - Codrey Electronics

    Jul 31, 2020 · Sulfr hexafluoride circuit breaker uses Sulfr hexafluoride ( Sulfur Hexafluoride) gas as an air quenching medium. This gas is electro-negative and it has high dielectric strength to absorb free electrons. This is very effective for high voltage applications ranging from 33kV to 800kV. It consists of moving and fixed contacts enclosed in a chamber called an arc interruption chamber filled with sf6 gas gas.

  • What is Sulfr hexafluoride 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.
