  • Operation principle of SF6 circuit breaker | Nader Circuit

    2020-9-9The SF6 circuit breaker adopts a self-energizing arc extinguishing structure, which mainly uses the high-pressure thermal expansion airflow in the pressure cylinder and the blocking effect of the hitting arc to increase the gas pressure in the high-pressure cylinder at the opening of the circuit breaker. The

  • Sulfur hexafluoride - Wikipedia

    2021-3-18Sulfur hexafluoride (SF6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant.[7][8] It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of sixSynthesis and reactions
