Application | Trailer-Mounted Mobile Transformer Oil Regeneration and Reclamation Plant

The PureTech mobile Double-Stage High Vacuum Transformer Oil Purifiers (Model DVOP) are used for transformer oil dehydration, degasification and filtration. As a necessary maintenance tool for power transformers, it can effectively remove free and soluble water, gases and particulate matters contained in the transformer oil, thereby increasing and maintaining the dielectric strength of transformer oil, performing good insulation function in power transformers.

The Enclosed Vacuum Transformer Oil Regeneration Treatment plant would be capable of performing the following functions:
i). Vacuum drying, degassifying and filtration of transformer oil by continuous circulation.
ii). Vacuum drying of the insulation of the power transformer.

Double-Stage High Vacuum Transformer Oil Purifiers (Model DVOP) adopt two-stage vacuum pumps, namely rotary vane vacuum pump and roots booster vacuum pump, they are especially applied to transformer oil treatment of 110KV,220KV,500KV,750KV,1000KV power transmission line.

In addition, Model DVOP can also be used as an vacuum drying and vacuum filling equipment during transformer maintenance.

Features | Trailer-Mounted Mobile Transformer Oil Regeneration and Reclamation Plant

• Double-stage high vacuum improve the effect and efficiency of oil dehydration and degasification.

• Multi-stage filtration ensures the high oil filtering accuracy.

• Multifunctional integrated equipment, can be used oil treatment, vacuum oil filling and vacuum drying.  (*More functions can be customized according to your requirements.)

• The uniquely designed “T” vacuum chamber enlarges the oil evaporation area more than the traditional design, so as to achieve a better dehydration and degassing effect.

• Model DVOP Transformer Oil Purifier can work offline or online under the safe operation.

• A standalone oil regeneration device can be mounted or connected on its basis for transformer oil regeneration.

• Online oil testers, trailer type with road-worthy wheels, weather-proof enclosure and other spare parts are available for selection.

Process in short | Trailer-Mounted Mobile Transformer Oil Regeneration and Reclamation Plant

1. Transformer oil filtration, dehydration, and regeneration can be achieved using a specialized transformer oil regeneration plant. This process involves several steps to ensure the oil is clean and free from impurities.

2. Firstly, the oil is subjected to filtration, where it passes through various filters to remove solid particles, moisture, and other contaminants. This step helps to improve the quality and purity of the oil.

3. Next, the oil undergoes dehydration, which involves removing any remaining moisture or water content. This is crucial as moisture can negatively impact the performance and lifespan of the transformer. Lastly, the oil is regenerated, which involves restoring its chemical properties and enhancing its dielectric strength. This ensures that the oil can effectively insulate and cool the transformer, prolonging its operational life.
