As an insulating gas, SF6 gas has non-toxic, non-combustible and good insulating properties. Its insulating strength is much higher than that of traditional insulating gas, and it has good arc extinguishing property. Therefore, SF6 gas is widely used in SF6 Electrical appliances.
Description
Because SF6 gas is expensive, and under the action of arc, electric spark and corona discharge, it will decompose and produce toxic components. Therefore, SF6 gas needs to be recovered when SF6 Electrical equipment is used.
The SF6 Gas Recovery and Purification unit is a special equipment for recovering and filling SF6 gas when manufacturing and maintaining SF6 Electrical equipment.
Features
1. The built-in filtration and absorption system can absorb impurities, water, decomposition products and oil in SF6 gas.
2. Integrated design and small volume make it easy to move and use.
3. High efficiency filter maintenance free system, greatly ensuring the quality of SF6 gas recovery.
4. The built-in phase sequence protector can avoid the worry that the host will reverse due to phase sequence error at any time.
5. All electrical systems are with high quality brand.
6. High quality casters will greatly protect the ground paint and reduce the labor required for pushing.
7. The SF6 Gas Recovery device is air-cooled without external water source.
8. The built-in temperature protection system can work normally even at - 20 ℃.
9. The built-in drying and heating system can ensure that the desiccant can be activated and regenerated by equipment heating after saturation, so the desiccant does not need to be replaced.
10. All ball valves are sealed elements with automatic compensation performance.
11. Our SF6 Gas Recovery and Purification unit has built-in electromagnetic valve power-off protection function, to prevent vacuum pump power-off or motor seizure return oil.
