Introductiongaz sf6 Gassf6 gas 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 vacuum circuit breakers are prevalent at medium voltages (< 72 kV). Sulfr hexafluoride circuit breakers are normally used for high voltagesystems ( 72 kV).
