1、 Purpose description
As an insulating gas, SF6 gas has non-toxic, nonflammable, and good insulation characteristics. Its insulation strength is much higher than that of traditional insulating gas, and it has good arc extinguishing performance. Therefore, it is widely used in SF6 electrical appliances. 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 applied. This device is a special device for recovering and filling SF6 gas when manufacturing and maintaining SF6 electrical equipment.
2、 Technical characteristics
1. Built in filtration and adsorption system can absorb impurities, water, decomposition products and oil in SF6 gas.
2. The integrated design and small volume are easy to move and use.
3. The highly efficient filter maintenance free system greatly ensures the quality of SF6 gas recovered.
4. The built-in phase sequence protector can eliminate the worry of the host's reversal due to phase sequence error at any time.
5. All electrical systems are of high-quality brands.
6. High quality casters will greatly protect the ground paint and reduce the labor required for pushing.
7. The whole machine is air-cooled without external water supply.
8. The built-in temperature protection system can work normally even under - 20 ℃.
9. The built-in drying and heating system can ensure that the desiccant can be activated and regenerated by heating the equipment after being saturated, so that the desiccant does not need to be replaced.
10. All ball valves are sealing elements with automatic compensation performance.
11. It has the power failure protection function of the built-in solenoid valve to prevent the power failure of the vacuum pump or the oil return due to the seizure of the motor.
