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.

Make/Break Contacts - In Power Circuit Breakers

In Sulfr hexafluoride circuit breakers, the same principle is employed, with insulating gas as the medium instead of air. In the “puffer” gaz sf6 breaker, the motion of the contacts compresses the gas and forces it to flow through an orifice into the neighborhood of the arc. Both types of Sulfr hexafluoride breakers have been developed for EHV (extra high voltage) transmission systems.

SF 6 gas is unique in that it meets all the stated requirements and is therefore an essential component within the power transmission and distribution network. Arcing occurs within circuit breakers whenever they operate. This process causes the absorption and deceleration of electrons, which in turn causes partial decomposition of the SF 6 gas.
