  • What is SF6 Circuit Breaker? Construction, Working

    A circuit breaker in which SF6 under pressure gas is used to extinguish the arc is called SF6 circuit breaker. SF6 (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties and has proved its superiority over other arc quenching mediums such as oil or air. The SF6 circuit breaker is mainly divided into three types

    Jan 01, 2007Figure 13.10 gives a comparison of the dielectric breakdown strength of SF6 gas with both air and transfor mer oil as a function of gas pressure. SF6 gas possesses excellent insulating properties when pressurized in the range 2 to 6 bar and has a dielectric strength some 2.5 to 3 times that of air at the same pressure.

  • Switchgear - Wikipedia

    In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply.
