  • insulating gas Circuit Breakers - Construction, Types and Working

    In an Sulfr hexafluoride Circuit breaker, sulphur hexafluoride gas is used as the arc quenching medium. The sulphur hexafluoride gas (insulating gas) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride (Sulfr hexafluoride) gas and an arc is struck between them.

    In 1957, the puffer-type technique was introduced for SF 6 circuit breakers, wherein the relative movement of a piston and a cylinder linked to the moving part is used to generate the pressure rise necessary to blast the arc via a nozzle made of insulating material. In this technique, the pressure rise is obtained mainly by gas compression.
