SF6 decomposition leak detection for 400kv

SF6 decomposition leak detection for 400kv

A leak detector must be used. If a leak is detected: WARNING Release the SF6-pressure before working on the screw connections of the gas chamber. If a leak is discovered, undo the leaking connection and check the sealing surface for damage or foreign bodies. Then fit a new seal, remake the connection and repeat the leak test.

    Jun 28, 2017A release of SF6 is very unlikely to be provoked by a fire. If it should occur, average temperatures are likely to be too low (because SF6 will be rapidly dissipated by convection to lower temperature regions) to lead to significant decomposition, which requires at least 500& C. SF6 is non-flammable and will
