China Sino-NSH VFD series Two-Stage High Efficiency Vacuum
Transformer Oil Filtration Plant, two-stage vacuum pump
I. Application of Transformer Oil Filtration Machine
The NSH VFD series Multi-Function Transformer Oil Filtration Machine is an oil
processing equipment designed to treat used transformer oil and
give it a new life. The machine has the function of dehydrating,
degassing, purifying, filtering and regenerating the transformer
oil. Therefore, the moisture, gas and impurity contaminants in the
transformer oil will be removed after being purified by our
transformer oil filtration machine.
II. Features of Transformer Oil Purifier
In addition to filtering, purifying, and regenerating transformer
oil, this machine can also be used for vacuuming and oiling the
transformer.
III.Oil Data After Filtration
| Dielectric Strength (BDV) | Kv | ≥75 | |||||||
| Water Content | PPM | ≤3 | |||||||
| Gas Content | % | ≤0.1 | |||||||
| Impurity Size | μm | ≤1 | |||||||
| Dielectric Loss | Tg | ≤0.005 | |||||||
| Interfacial Tension | mn/m | ≥40 | |||||||
IV. Working Flow of Transformer Oil Purifier
1. The insulating oil is conveyed into the plant by means of
pressure difference. Oil will firstly flow through a coarse filter,
which can filter out large particles and mechanical impurities from
insulating oil.
2. Oil is heated uniformly by electric heater with less specific
heat transfer of 1.7w/cm², thus the deterioration of the oil caused
by overheating is avoided during this process.
3. The special vacuum tank create a large oil surface and a
resulting thin film, where the oil flows track and static water
evaporation area were expanded to the largest extent, so that the
effect of dehydration and degassing is maximized effectively. The
particular double-stage vacuum pump system and pressure-boost
technical make vacuum degree in vacuum tank higher than that in
common oil purifier plant. Specially-designed oil level controller
in the vacuum tank assures a continuous oil flow-through in the
plant, thus resulting in an optimised dehydration and degassing of
the oil. With the double-stage vacuum oil purifier, the
installation period and maintenance period can both be shortened
effectively.
4. After degassing and dehydration under vacuum, the oil is
conveyed by through the fine filter and out of the plant.
5. Oil Circulation is recommended to achieve better effect of
purification and filtration.
