Application | Trailer Mounted Vacuum Insulating Oil Filtration Machine

mobile vacuum insulating oil filtration machineThe PureTech Trailer Mounted Vacuum Insulating Oil Filtration Machine provides an effective solution to handle the contamination of free water or dissolved water, dissolved gases and particulate matters in insulating oil. PureTech mobile Double-Stage High Vacuum Mobile Transformer Oil Purification Plants (Model DVOP) are used for the conditioning and purification of aged insulating oil. As part of the transformer lifecycle management, regular servicing is essential, transformer oil treatment is very necessary, the process includes 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 by single pass or several passes, thereby increasing and maintaining the dielectric strength of transformer oil, performing good insulation function in power transformers. Furthermore, depends on different demands of customers, our plants can be made as manually controlled or PLC controlled, integrating fully automatic functions suitable for off-line (de-energized transformer) as well as
on-line (energized transformer) filling, purification and filtration processes.


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.

Process in short | Trailer Mounted Vacuum Insulating Oil Filtration Machine

1. Filtration: Adopts one built-in filters to protect the oil purification plant against coarse contamination. And  two stages of fine filters to control the pollution level by removing 99.9% of the impurities over 5 (or 1) microns, and to achieve the final cleanliness of transformer oil.

2. Oil Heating: the aged transformer oil is heated by electrical heater with thermostat, which can brought the oil to the required heating temperature but avoid of overheating or dry burning. The specially designed horizontal heating tubes and generously dimensioned heating surface lower the heating density and lower the aging of transformer oil.

3. Degassing System:  this is where oil dehydration and oil degassing happens. This degassing system has been optimised and expanded with an automatic foam control. It has greatly expands the exposure surface of moisture under the vacuum, therefore greatly improve the efficiency of Transformer Oil Dehydration and degassing.

4. Vacuum Pump system:  it adopts a double-stage high vacuum pump system, used for evacuation of gases and create a vacuum for the degassing system. While it is not working for oil dehydration, it can be used standalone, as a separate vacuum pump system for transformer evacuation, to dry transformers and the insulation paper.

5. Oil transfer: the whole plant equipped oil pump to convery the transformer oil to different stages by means of differential pressure. It  can be optionally added frequency inverter to allow variable flow rates.

6. Other online measuring instruments and accessories: this oil purification plant can be included in some built-in measuring instruments and accessories, for example, built-in moisture content tester to check the real-time ppm value of transformer oil,  trailer-mounted type with water-proofing cover to protect the plant from harm of extreme weather or strong sunshine outdoor, etc.
