Application
The transformer filtration system is suitable for purifying of large scale power transmission units higher than 110KV and transformers of main state grid.
Transformer oil filter features:
1. It can quickly remove the harmful components in the oil such as moisture, gas and impurities in the transformer oil,
2.Improve the lubrication performance of transformer oil, reduce the rust or corrosion of oil-using equipment due to excessive moisture or impurity content of transformer oil, and prolong the service life of oil-using equipment

The Advantages of oil recycle machine:
1.outdoor use with roof,close/open ventilation window,skid basic mounted,enough lifting hook.
2.Besides the features of ZJB series vacuum purifier, it’s added roots booster pump system, the secondary high vacuum air extracting system for rapidly removal of gas and moisture. It avoids the weakness that displacement sharp declines while the vacuum purifier working at a high vacuum degree. Performance of one cycle of processing is equivalent to two units common vacuum purifier.
3.High extraction speed double vacuuming systems which is able to utmostly enhance the vacuum environment of internal vacuum tank to make high vacuum. Ultimate vacuum ≤5Pa, working vacuum ≤35Pa, keep the oil temperature during processing to fulfil the vacuuming requirement of installation or maintenance site, highly reduced oil processing period.
4.After filtration, the di-electric strength and flash point is higher, after one cycle of filtration, breakdown voltage increases 3-5kv, effectively avoid oil ageing resulted from repeatedly heating.
5.High performance configuration: advanced infrared liquid level control system, pressure protection system and oil pump interlock controlled to ensure long time and safely operation.
6.The unit able to maintain energized transformers and long time online operation, fitted automatic de-foam facility for working in plateau area, it can be automatically working without people’s supervision.High precision and intelligent degas system is able to remove all sorts of gas from oil rapidly, avoid the existing of hydrogen, ethyne, ensure the content of ethyne of oil after treated to “zero”.
7.One machine two function, both vacuum purifier and vacuum unit, it can be used for vacuum filling for insulation units, it is able to reduce transformer installation and maintenance time, the product is at the leading position of this field.
Installation:
1. The transformer filtration system should be placed on a level ground and placed stably.
2. Since the machine is mobile, the user does not need to design an installation foundation, just move the machine to the flat ground near the oil tank.
3. The selection of the power input line is better to choose three phase voltage, if you want to use single stage voltage, then check in detail with factory.
