7Insulation Oil Filtration Machine for 30 MVA Power Transformer,
High Voltage Transformer Oil Dehydration
I. Application of Transformer Oil Purifier
The double-stage vacuum oil filter is more suitable for 110KV power
system and above transformer oil filtration purification treatment,
of course, it is also suitable for 10KV or 35KV power system
insulation oil filtration.The insulation strength value of the
double-stage vacuum oil filter is higher, generally ranging from
70KV to 85KV depending on the oil condition.
The doubleo-stage vacuum transformer oil purifier with double-stage
vacuum system adds a Roots booster pump to achieve a higher
ultimate vacuum, not only improve the vacuum pumping speed but also
the faster dehydration rate.
II. Benefits of Transformer Oil Purifier
1. Removes Dissolved Moisture Transformer Oil
2. Reduces combustible gases and oxygen
3. Improves oil dielectric values
4. Improves transformer power factor
5. Extends oil service life
6. Extends transformer service life and reliability
7. With electrical control inter-lock design. Vacuum pump system,
oil transfer system and heating system are interlocked in control.
8. Precise filtration system to remove impurities at a maximum
extent.
9. Multi Safety operation devices. Phase-sequence, phase lost,
emergency stop, etc.
III. Options of Transformer Oil Purifier
1. Weather-proof enclosure for outdoor application.
2. Trailer-mounted to increase mobility.
3. Transformer evacuation as optional function.
4. PLC control with Fully Touch Screen make the machine a
fully-automatic plant.
5. Customized design is also acceptable.

| Gas Content | % | ≤0.1 | |||||||
| Impurity Size | μm | ≤1 | |||||||
| Dielectric Loss | Tg | ≤0.005 | |||||||
| Interfacial Tension | mn/m | ≥40 | |||||||
V. 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.
