IntroductionSF6 GasSF6 Circuit Breaker TypesConstruction and Main ComponentsIn power systems, circuit breakers are used to switch electrical equipment and networks under normal and fault conditions. The primary function of a circuit breaker is to interrupt the flow of current (load or short circuit) by opening its contacts and thereby isolating the switched parts of the system. The design and working of a circuit breaker depend on its application and voltage rating. Moulded case technology (with air at atmospheric pressure) is used at low voltages (< 1000 V), whereas air blast and …See more on savreeSF6 Circuit Breakers Construction Working Principle electricalengineeringinfo/2016/03/sf6 circuit breakers working and...2016/3/17The SF6 circuit breakers have been found to be very effective for high power and high voltage service. Construction of SF6 circuit breaker: The figure above shows the parts of a typical SF6 circuit breaker .It consists of fixed and moving contacts enclosed in a chamber (called arc interruption chamber) containing SF6 gas.
