  • sf6 Gas Mixture unit for High Speed Rail

    It uses a gas mix similar to the air we breathe, made up of nitrogen (80%) and oxygen (20%), as a carbon free alternative to SF6 which has traditionally been the method of insulation in high voltage switchgear since the 1960s. The chemical properties of SF6 gas make it ideal for electrical insulation and arc quenching in high-voltage switchgear.

    Feb 20, 2021 · Separation of the movable contacts is via an opening valve that allows a high pressure flow of SF6 gas at 14 kg/cm 2 to strike the arc and extinguish them. Since SF6 gas is electronegative and has a powerful love for free electrons, it absorbs the conducting free electrons in the arc to form immobile negative ions. Advantages of SF 6 circuit breaker

  • Sulfur hexafluoride circuit breaker - Wikipedia

    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.
