What is the SF6 Gas Filling Equipment Procedure?

Correct operation process of SF6 gas vacuum and inflatable device.

Recover SF6 gas

• When the SF6 gas is extracted, the gas automatically flows through the purification filter in the unit.
• Then it is compressed and cooled by the SF6 compressor, and then the SF6 gas is stored in the storage tank. (Can be in gaseous or liquid form)

Vacuum

• The air and moisture in the air chamber and the switch are removed by a vacuum pump.

Fill with SF6 gas

• Fill the purified and dried SF6 gas from the storage tank into the air chamber that has been evacuated until the pressure in the air chamber reaches the set working pressure.

Functions of SF6 Gas Filling Equipment

The SF6 Filling Equipment consists of the SF6 compressor, vacuum pump, vacuum system with anti-oil return device, condensation system, liquid storage tank, purification system with built-in renewable dry filter, dust filter, ball valve, vacuum gauge, and electrical control, pressure Detection and alarm devices, instrument panels, and other auxiliary facilities.

• The machine can vacuum all kinds of SF6 electrical equipment.
• Fill electrical equipment with SF6 gas.
• Recover SF6 gas from the electrical appliances used, and carry out purification treatment at the same time.
• Compress and store SF6 gas in the storage tank.

This Sf6 Filling Equipment is suitable for SF6 electrical appliances and GIS combined electrical appliances.
