Transformer Manufacturer Maintenance Tool, Transformer Oil
Filtration Equipment, powerful ability in vacuum dehydration
(MAQUINA PARA EL REFILTRADO DE ACEITE DIELECTRICO)
I. Application of Transformer Oil Filtration Machine
NSH VFD series double stages vacuum transformer oil filtration
machine is especially applied to 500KV,750KV and 1000KV AC power
grid and ±660KV, ±800KV DC power grid for the insulating oil
treatment and maintenance. NSH VFD series Transformer Oil
Filtration Machine are very powerful in abilities of vacuum
dehydration, degassing and filtration for transformer oil, inductor
oil, cable oil, including used transformer oil and new transformer
oil, both silicon oil and mineral oil can be treated.
II. Benefits of Transformer Oil Filtration Machine
1. Advanced two-stages large capacity dehydration and degassing
system which adopts large area three dimensional flash evaporation
technique to remove harmful material in the transformer oil such as
water, air, gas, hydrocarbon, etc.
2. This unit can be widely used in transformer manufacturers,
transformer installation and maintenance, vacuum filling,
transformer evacuation, etc.
3. Equipped with automatic control system, to make the operation
much easier.
4. This oil filtration machine adopts humanization design with low
noise, long free-maintenance time and energy saving to lower the
operation cost.

V. Working Flow of Transformer Oil Filtration Machine
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.
VI. Available Style of Transformer Oil Filtration Machine
1. Fixing type,mobile type with four wheels and mobile type with
trailer.
2. Normal appearance type,shelf-covering type and explosion-proof
type.
3. Avaliable in different color.
