SF6 Gas Recovery DevicePurpose Description
SF6 gas, as an insulating gas, is non-toxic, non-flammable, and has excellent insulating properties. Its insulation strength is much higher than traditional insulating gases, and it also has good arc-extinguishing properties, so it is widely used in SF6 electrical equipment. Since SF6 gas is expensive and decomposes under the action of arcs, sparks, and corona discharge to produce toxic components, it is necessary to recover SF6 gas when using SF6 electrical equipment. This device is a special equipment for recovering and refilling SF6 gas during the manufacturing and maintenance of SF6 electrical equipment.
SF6 Gas Recovery DeviceTechnical Features
1.2.1. Built-in filtration and adsorption system can adsorb impurities, moisture, decomposition products, and oil in SF6 gas.
1.2.2. Integrated design and compact size facilitate movement and use.
1.2.3. Efficient maintenance-free filtration system greatly ensures the quality of recovered SF6 gas.
1.2.4. Built-in phase sequence protector eliminates any worry about the main unit reversing due to phase sequence errors at all times.
1.2.5. All electrical systems use high-quality brands.
1.2.6. SF6 Gas Recovery Device, high-quality casters greatly protect the floor paint and reduce the labor required for pushing.
1.2.7. The whole machine is air-cooled, no external water source needed.
1.2.8. Built-in temperature protection system can work normally even at -20 degrees Celsius.
1.2.9. 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.
1.2.10. All ball valves are sealing elements with automatic compensation performance.
1.2.11. SF6 Gas Recovery Device, has built-in solenoid valve power-off protection function, preventing oil return from the vacuum pump due to power failure or motor seizure.
