MAQUINA PARA EL REFILTRADO DE ACEITE DIELECTRICO,
tratamiento del aceite dieléctrico,Bomba de vacío de doble etapa
I. Application of Transformer Oil Filtration Machine
NSH VFD series is maily used for purifying the insulating oil in
all kinds of large power equipments that are above 110KV especially
for the latitude is over 500 meters.
The machine can remove the free water, soluble water, gas, acid,
free carbon(polarity material) and other impurities
high-efficiently, increasing the pressure force and quality of oil,
improving the insulation oil dielectric value, making sure the
electric device running safely. the NSH VFD transformer oil
purifier can recycle the insulation oil, which includes transformer
oil, break oil, capacitor oil, switch oil, mutual oil, cable oil
and so on. Meanwhile, this machine can inject oil into the electric
device under the vacuum situation. Besides the insulation oil, VFD
also can purify any non-emulsification oil. It is good oil
purification system for the power station, transformer station, and
other relative line.
II. Benefits of Transformer Oil Filtration Machine
1. Add Roots Pump supercharge system and secondary high vacuum
separation dehydration and degasification system on the basis of
high efficiency vacuum purifier, which enable the vacuum limit
reaching ≤3Pa.
2. Being able to eliminate water, gas and impurities etc. harmful
contaminants quickly and effectively under high vacuum and high
speed operation status, could enhance the breakdown voltage up to
75KV.
3. Being able to remove little tiny water and various gases from
oil, and ensure that there is no acetylene in oil.
4. This machine can inject oil, transformer vacuuming.
III. 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.
