Transformer Oil Purifier Maintenance Standard

The transformer oil purifier is a mechanical equipment that filters solid impurities and moisture in oil, improves oil quality and improves transformer oil insulation strength. It is a special equipment used in power plants, power stations, power companies, metallurgy, petrochemical, railways and other industrial and mining enterprises to purify unqualified electrical insulating oil. It can also vacuum-inject and extract insulating power equipment and vacuum-dry electrical equipment moisture.


The inspection and maintenance standards of the transformer oil purifier are as follows:


1. Test whether the breakdown voltage of the filtered oil reaches the standard voltage. There is a special tester for this oil breakdown voltage value, which can be equipped with a withstand voltage automatic printing tester, which is convenient and intuitive.


2. Whether the water content of the oil exceeds the requirement. The inspection of this project generally requires the inspection of oil samples, but there are also special micro-water testers for reference.


3. Whether all impurities in the crude oil have been removed. That is, check whether the filtration accuracy of the oil and the particle distribution of the oil meet the standards.


4. Whether the gas content in the filtered oil meets the requirements. Check whether the oil still contains acetylene, hydrogen, CO2 and other harmful gases.


5. Whether the filtration loss is within the acceptable range. Check whether the dielectric loss of the oil meets the requirements and see whether the quality of the transformer oil is damaged after treatment.


6. The acidity and alkalinity of the filtered oil must be consistent with the crude oil. Test the pH value. If it does not meet the standard, it must be purified separately with an independent regeneration device.


7. How much smoother is the filtered oil than the original oil and how much is the particle size reduced? See whether the chemical additives of the oil are lost and whether the impurities in the oil have been cleaned up.


As a key equipment for the maintenance of power equipment, the strict implementation of the maintenance standards of the transformer oil purifier is directly related to the reliability and life of the transformer operation. By regularly testing indicators such as breakdown voltage, water content, impurity content, gas content, filtration loss, acidity and alkalinity, and oil smoothness, it can ensure that the performance of the insulating oil meets the standards and ensure the safe and stable operation of the power equipment.


In the future, transformer oil purification technology will continue to develop in the direction of high efficiency, energy saving and environmental protection, providing more reliable oil management support for the power industry. Only by strictly following the maintenance standards and using advanced technical means can the role of transformer oil purifiers be maximized to ensure the safe and efficient operation of the power system.
