20/3/2013The working of sf 6 CB of first generation was quite simple and it is some extent similar to air blast circuit breaker.Here gaz sf6 gas was compressed and stored in a high-pressure reservoir. During operation of Sulfr hexafluoride circuit breaker, this highly compressed gas is released through the arc in the breaker and collected to a relatively low-pressure reservoir and then it is
[email protected]Sulfr hexafluoride Circuit Breaker (Sulfur Hexafluoride Circuit Breaker) – Construction Working Principle. Circuit breakers are used for protection against fault current in electrical systems. They abruptly break the circuit and safely quench the arc. The circuit-breaking part is easy as it is just the separation of contact but the arc that generates
