New Transformer Oil Filtration and Refilling Machine, electrical insulation oil

Product Specification

Above 110KV Substation Necessary Maintainance Device - Transformer Oil Purifier with Vacuum System

I. Application of Transformer Oil Filtration Machine
NSH VFD series transformer oil purifier can remove pollutants in transformer oil, such as moisture, gas, mechanical impurities and tiny particles, quickly and transparently, so that the transformer oil becomes clean and transparent, and the oil is re-calibrated for use in transformers.
After being treated by this oil filter, the contaminated transformer oil can reach the new oil standard, the water value is lower than 3PPM, the impurity content is less than 1Micron, and the withstand voltage is as high as 75~85KV.
II. Benefits of Transformer Oil Filtration Machine

1. NSH VFD Transformer Oil Purifier does not produce polluting gases such as acetylene during the processing of oil, and does not cause secondary pollution to transformer oil.
2. NSH VFD Transformer Oil Purifier can be used to evacuate the transformer. Thanks to the electronic vacuum gauge, it can detect the exact vacuum inside the transformer. The user can judge whether the vacuuming is completed according to the degree of the electronic vacuum gauge.
3. NSH VFD Transformer Oil Purifier is an oil filtration device with versatility, safety and high efficiency. It is an indispensable equipment for any power plant, substation and power maintenance company.

IV. 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.
