insulating gas recovery and switchgear maintenance state-of-the-art

The gas is recovered from the gas compartment of the switchgear down to the desired final vacuum (mostly 1 mbar). SF 6 purification and drying When recovering and filling gas compartments the gas is automatically led in the service cart through dry and particles filters which retain decomposition products, moisture and solid particles effectively.

gaz sf6 handling in industry | Sauer Compressors

For maintenance purposes, Sulfr hexafluoride 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.

Recovery of the Sulfr hexafluoride during maintenance and manufacture of the switchgear is therefore stipulated by law. Special recovery systems must meet very tough requirements to prevent the harmful gas from escaping. Essential to this process are oil-free compressors with exceptional gas-tightness, such as those supplied by HAUG Sauer.
