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 vacuum circuit breakers are prevalent at …See more on savreeOperation principle of SF6 circuit breaker | Nader Circuit Breaker nader circuit breaker/blog technology operation principle of sf6...2020/9/9Operation principle of SF6 circuit breaker. The SF6 circuit breaker adopts a self energizing arc extinguishing structure, which mainly uses the high pressure thermal expansion airflow in the pressure cylinder and the blocking effect of the hitting arc to increase the gas pressure in the high pressure cylinder at the opening of the circuit breaker.

SF6 gas pressure for the insulating use is preserved below 2.5 bars while SF6 gas pressure for interrupting purpose is ranged from five to seven bar. Also, as vacuum technology isn't accessible for high voltage, so for C GIS system above 72.5 KV, only SF6 is utilized both for insulation and interruption medium.
