siemens IR SF6 leak check

Apr 12, 2021 · I've had experience with Indoor GIS that cast aluminum alloy was manufactured so badly (becomes porous) and SF6 was leaked, loosing pressure. To find out such a leakage you should wrap GIS compartment (under pressure) by means PVC sheet, leave it for 48 hours and pierce by SF6 detector under wrapping to check is some gas collected.

  • SF6 circuit breaker maintenance - Siemens USA

    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.

  • Hints for maintaining type SP SF6 power circuit - Siemens USA

    Air valve leaks Some customers have reported leaking air valves. In our investigation to determine the cause, we have concluded that temperature plays a large part in causing the leaks, especially in areas with high ambient temperatures. This has resulted in hardened "o-rings" which leak in some valves.
