Product Details

Technical Parameters:

1. Recovery

Initial recovery pressure ≤0.8MPa

Final recovery pressure ≤50KPa

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

2. Filling

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

3. Vacuuming

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

For a 1 m³ SF6 gas volume with an initial pressure of 0.1MPa, vacuuming to 133Pa takes less than 1.0 hour.

4. Storage

Storage container volume 0.015m³

Product Functions:

1. Vacuuming and vacuum measurement for the device itself, SF6 switches, and GIS

2. Vacuuming and vacuum measurement for liquefaction tanks

3. Vacuuming and vacuum measurement for the device itself

4. Filling SF6 switches

5. Recovery of SF6 gas from electrical equipment, including moisture treatment and oil treatment

6. Drying and purification treatment of recovered and refilled SF6 gas

7. Recovery, liquefaction storage, and residual pressure measurement of SF6 gas in SF6 electrical equipment

8. Can accommodate an 80-liter storage tank inside the device body.

9. Compressed liquid storage of SF6 gas.

10. This device is mobile.

Precautions:

1. Before use, check that all connections are correct and the interfaces are sealed.

2. The oil level of equipment components should be appropriate.

3. The vacuum pump must not run in reverse.

4. Do not open vacuum gauge V9 when there is gas pressure in the equipment.

5. The filter element should be replaced after 5000 hours of operation. The molecular sieve should be replaced after 10000 hours.

6. When recovering gas, the refrigeration system can be turned on 15-30 minutes in advance.

7. When the refrigeration system is turned on, a small amount of condensed water will be discharged, which can be handled appropriately.
