• Sulfr hexafluoride Circuit Breaker Types, Working Principles Maintenance.

    Feb 20, 2021 · The interrupter of the Sulfur hexafluoride circuit breaker comprises a fixed and movable contact shield in a chamber called the arc interruption chamber. The chamber is then connected to the gas reservoir of the circuit breaker. When the breaker senses fault, it releases the high-pressure gas from the reservoir to cool and extinguish the arc.

    Sulfur hexafluoride is inert in the troposphere and stratosphere and is extremely long-lived, with an estimated atmospheric lifetime of 800–3,200 years. [29] Measurements of SF 6 show that its global average mixing ratio has reached over 10 parts per trillion (ppt) as of April 2020, and is increasing by about 0.35 ppt (3.5 percent) per year.

    Sulfur hexafluoride is generally used in present high-voltage circuit breakers at rated voltage higher than 52 kV. Into the 1980s, the pressure necessary to blast the arc was generated mostly by gas heating using arc energy. It is now possible to use low-energy spring-loaded mechanisms to drive high-voltage circuit breakers up to 800 kV.
