SF6 gas is a potent greenhouse gas commonly used in electric power systems and other industries. It is non-toxic and thermally stable, but it can remain in the atmosphere for over 3,000 years if released into the environment. To minimize the risk of emissions, it is crucial to use proper gas handling practices.
our team has extensive experience working with gas-insulated equipment (GIE). They have compiled pro tips for handling SF6 gas, such as relieving pressure before disconnecting, using proper start-up procedures, preparing equipment before handling SF6 gas, recovering gas on failed breaker, checking filters on recovery systems, testing SF6 cylinders after storage, and using nitrogen to rinse the recovery system.
Relieving pressure before disconnecting a hose from a fitting is essential, as it helps prevent damage to the temporary O-ring. Proper start-up procedures should be followed, and hoses should be kept in vacuum before and after handling SF6 gas. If a breaker fails, a gas analysis should be performed, and a small amount of SF6 gas should be recovered beforehand.
If a recovery system becomes contaminated with sulfur dioxide (SO2), nitrogen can be used to rinse out internal components, preventing further contamination and corrosion. Proper PPE should be worn, and items requiring disposal should be neutralized in compliance with safety standards.
