EATON sf6 Treatment Decomposition

EATON sf6 Treatment Decomposition

Due to the above reasons, SF6 is used mostly in applications that allow reclamation as opposed to using it on equipment that requires release of the gas, only to be re-filled with virgin SF6. ENERVAC produces a complete line of SF6 recovery and test equipment, from full sized gas reclaimers down to small decomposition detectors.

    SF6 gas will resolve into subfluorides. After cooling down, these active subfluorides will quickly return back to SF6 gas. Therefore, SF6 gas which is used under sealing for a long time will not decrease or deteriorate, although under the effect of arc extinguishing several times. The amount of arc decomposition depends on

  • SF6 gas as insulating and arc-quenching medium

    Sep 20, 2011 · Arcing causes the decomposition of very small amounts of SF6 gas. The decomposition products react with water, therefore the gas’s moisture content, particularly in the circuit-breaker, is controlled by drying (molecular) filters. Careful evacuation before first gas filling greatly reduces the initial moisture content.
