sf6 Gas Mixture cb separating unit

In order to minimize the emission of SF6 gas, the N2 – SF6 and CF4 – SF6 gas mixture may be used in circuit breaker in future, as the substitute of pure SF6. It must always be taken care of that, no SF6 gas comes out in atmosphere during maintenance of the CB. On the other hand, SF6 circuit breaker has the major advantage of low maintenance.

  • COLD-WEATHER APPLICATION OF GAS MIXTURE (SF6/N2,

    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 the SF 6/CF 4 mixture is, in most cases, able to retain its full interrupting capability at -50oC with only very small values of grading capacitance.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    Operating principle. Current interruption in a high-voltage circuit breaker is obtained by separating two contacts in a medium, such as sulfur hexafluoride (SF 6), having excellent dielectric and arc-quenching properties. After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity.
