Maintenance sf6 gas switchgear Charging

Switchgear with SF6 gas. There are three principal designs for SF6 insulated switchgear. With the first two, known as controlled pressure systems and closed pressure systems, release of SF6 is unavoidable in practice. This is because the systems require maintenance in the course of their service life, at which point leakage occurs.

    8. SF6 gas leakage - SF6 breakers (live and dead tank) typically have a combination of static seals (O-rings and gaskets) as well as dynamic seal assemblies where the mechanism energy is transferred through to the interrupter assembly. Over time, seals degrade due to environmental conditions and exposure and will need to be replaced.

  • SF6 handling in industry | Sauer Compressors

    For maintenance purposes, SF6 must be evacuated from gas insulated switchgear. To do this, the gas is pumped out into portable recovery systems (see photo), where it is then filtered and fed to the compressor, which compresses it. The final pressure is generally 40 barg. Once cooled, the gas can be stored in a liquid state.
