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 filling SF6 gas during the manufacturing and maintenance of SF6 electrical equipment.



LH-GT SF6 Portable Recovery Unit



Technical Parameters:



Initial recovery pressure ≤0.8MPa



Final recovery pressure ≤50KPa



Recovery time: For 1 m3 of SF6 gas at an initial pressure of 0.8MPa, recovery to a final pressure of 50KPa takes less than 2.5 hours.



For 1 m3 of SF6 gas at an initial pressure of 133Pa, filling to 0.8MPa takes less than 0.8 hours.



The ultimate vacuum of the device is less than or equal to 10 Pa



For 1 m3 of SF6 gas at an initial pressure of 0.1MPa, evacuating to 133Pa takes less than 1.0 hour.



Storage container volume 0.015m3



Nominal liquid storage capacity 20kg



Maximum storage pressure 3.8 MPa



For SF6 gas with a moisture content below 1000PPM (by volume), after one recovery and purification by this device, the moisture content is less than 60PPM (by weight), and the oil content is less than 10PPM (by weight)
