  • Essay | The Function And Principle Of A Circuit Breaker

    Mar 23, 2015 · The working of SF6 CB of first generation was quite simple, it is some extent similar to air blast circuit breaker. Here SF6 gas was compressed and stored in a high pressure reservoir. During operation of SF6 circuit breaker this highly compressed gas is released through the arc and collected to relatively low pressure reservoir and then it pumped back to the high pressure reservoir for reutilize, Innovation of puffer type design makes operation of SF6 CB much easier.
