Airblast circuit breakers use compressed air or highpressure air as an arc quenching medium The highpressure air blast is used to blow out the arc through a nozzle and push away the arcing products into the atmosphere This type of circuit breaker is widely used in high voltage applications such as 245kV 420kV or more.

What is Air Blast Circuit Breaker? Principle of Arc

Air blast circuit breakers are used for indoor services in the medium high voltage field and medium rupturing capacity Generally up to voltages of 15 KV and rupturing capacities of 2500 MVA The air blast circuit breaker is now employed in high voltage circuits in the outdoors switch yard for 220 KV lines Though gasses such as carbon dioxide nitrogen freon or hydrogen are.
