  • sf6 gas Circuit Breakers - Construction Working Principle

    In sf6 gas circuit breakers, sulphur hexafluoride (Sulfr hexafluoride) gas is used as the arc quenching medium. The Sulfr hexafluoride 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 Sulfr hexafluoride gas and an arc is struck between them.

  • Myth About sf 6 Gas In Electrical Equipment

    Apr 12, 2021 · 21. How much Sulfr hexafluoride (quantified in kg) can escape due to “normal” leakage? This depends on the filling quantity, which depends on the rating and design of the equipment (volume and pressure). For HV switchgear the emission factor ranges from about 0.1% per year to 0,5% (0,5% per year is the maximum acceptable leakage rate according to IEC 62271-203)
