Sulphur Hexafluoride (SF6) circuit breaker: In SF6 circuit breakers, sulphur hexafluoride (SF6) gas is used as the arc quenching medium. The SF6 is an electro-negative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow of SF6 gas and an arc is struck between them.[email protected]

Jun 11, 2016A circuit breaker in which SF 6 under pressure gas is used to extinguish the arc is called SF 6 circuit breaker. SF 6 (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties which have proved its superiority over other arc quenching mediums such as oil or air. The SF 6 circuit breaker is mainly divided into three types.
At the time of production, SF6 gas circuit breakers are subject to a high-voltage withstand test. This incorporates an AC High-Potential (Hi-Pot) test transformer capable of achieving the required high-voltage levels (per industry standards). Therefore, field Hi-Pot testing is also not necessary or required. The insulating material used in the manufacture of modern SF6 gas circuit breakers is synthetic,Get Price

We have been purchasing mixed-gas circuit breakers since 1988. These initial circuit breakers were purchased with a 0.5 MPa mixture (0.31SF 6 + 0.2N 2) at 20 oC. In 1990, a new gas mixture of SF 6 and CF 4 became available. This new mixture offered some very important advantages over the SF 6 and N 2 mixture. A circuit breaker filled with theGet Price
