SF6 Gas Vacuum Pumping and Filling Device Technical Features
1. Built-in filtration and adsorption system, which can adsorb impurities in SF6 gas, moisture, decomposition products, and oil, etc.
2. Integrated design and compact size facilitate mobility and use.
3. Efficient filtration and maintenance-free system greatly ensures the quality of recovered SF6 gas.
4. Built-in phase sequence protector eliminates any worry about the main unit reversing due to phase sequence errors at any time.
5. All electrical systems use high-quality brands.
6. High-quality casters greatly protect the floor paint and reduce the labor required for pushing.
7. The whole machine is air-cooled, no external water source needed.
8. Built-in temperature protection system ensures normal operation even at -20 degrees Celsius.
9. Built-in drying and heating system ensures that after the desiccant is saturated, it can be activated and regenerated by heating the equipment, thus eliminating the need to replace the desiccant.
10. All ball valves are sealing components with automatic compensation performance.
11. Built-in solenoid valve power-off protection function prevents vacuum pump oil return during power outage or motor seizure.
Main Functions:
(1) Vacuum pumping and vacuum degree measurement for the device itself, electrical equipment, storage tanks, etc.
(2) Recovery of SF6 gas from electrical equipment.
(3) Drying and purification treatment of recovered and refilled SF6 gas.
(4) Refilling SF6 gas into electrical switches.
(5) Compressing and storing SF6 gas in liquid form.
Main Technical Parameters
1. Recovery
Initial recovery pressure ≤0.8MPa
Final recovery pressure ≤50KPa
Recovery time: For 1 m3 SF6 gas volume at initial pressure 0.8MPa, recovered to final pressure 50KPa, the recovery time is less than 2.5 hours.
2. Filling
