dilo circuit breaker SF6-alternative gases system

The environmental problems caused by greenhouse gases have received unprecedented attention. Sulfur hexafluoride (sf 6), which is the preferred gas for use in gas-insulated switchgear (circuit breakers, disconnect switches, etc. for high-voltage electrical circuits), has a very high global warming potential, and there is a large international effort to find alternative gases.

  • Comparison Between Vacuum and SF6 Circuit Breaker

    In an SF6 circuit-breaker, the current continues to flow after contact separation through the arc whose plasma consists of ionized SF6 gas. For, as long as it is burning, the arc is subjected to a constant flow of gas which extracts heat from it. The arc is extinguished at a current zero, when the heat is extracted by the falling current.

    Most interesting is the molecule's self-healing abilities. The molecules within the gas only begin to break down at a temperature of 380 degrees Fahrenheit - once the heat source is removed, the atoms will recombine. The chemical properties of SF 6 make it ideal for use within circuit breakers and switchgear.
