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.
