Description of Mobile Oil Treatment Plant

PureTech Mobile Oil Treatment Plant for Power Transformer (Model DVOP) is mainly used for high voltage power transformers 400/230KV with different power capacity varies up to 300 MVA, 230/66KV with different power capacity varies up to 125 MVA. The oil treatment plant is capable to re-improve the power transformer oil characteristics up the required or recommended value by transformer manufacturers or IEC standards.

DVOP Double-stage High Vacuum Mobile Oil Treatment Plant is designed to carry out the operations and functions of filtration, dehydration and degasification of dielectric oil. It is workable for vacuum filling-up transformers with insulating oil and periodic maintenance at electricity transmission substations.



Performance of Mobile Oil Treatment Plant

Moisture content shall be decreased to below 5 ppm according to IEC 60814 or ASTM D1533 standards.mobile oil treatment plant for power transformers

Gas content shall be reduced down to below 0.1% according to the IEC 60567 or ASTM D2945 standard.

• Three stages of filter cartridges to reduce the particles over 1 micron in the oil.

Dielectric strength of transformer oil shall be improved above 75KV.


Capacity of Mobile Oil Treatment Plant

1. Oil flow rate ranges from 1,800 ltr/hr to 18,000 ltr/hr, suitable for various demands of transformer maintenance.

2. At least two-stage Heating with thermostat, ensure uniform heating and prevent overheating.

3. Double-stage vacuum pumps create and maintain sufficient and high vacuum level inside the oil treatment plant, maximumly ensure the efficiency and effect of oil dehydration/degassing.

4. Multi-stages filter cartridges keep the filtering precision higher than 1 micron.

5. Multi protection settings, oil level in the vacuum chamber works together with electrical heater and solenoid valve, phase-break protection, etc.

6. Oil treatment plant mounted on a mobile trailer with metallic cover. Easy to access and operate in different transmission substations.

7. Transformer vacuuming can be performed by this oil treatment plant (OPTIONAL).
