Transformer oil plays a key role in ensuring the longevity and reliability of transformers, serving not only for cooling, but also for electrical insulation. Over time, oil loses its insulating and physical properties due to oxidation and contamination by water, gases and particulates. In this case, specialists are faced with the task of cleaning and regenerating the oil in order to restore its original characteristics and extend the life of the transformer.
The process of cleaning transformer oil begins with the removal of mechanical impurities. This is usually achieved by filtering the oil through fine mesh filters that trap dust and metal particles. This method is effective in removing visible contaminants, but it does not affect the chemical state of the oil.
Next is the process of degassing and dehydration, which is often carried out by vacuum processing. The vacuum helps remove dissolved gases and water from the oil, which is important to maintain its insulating properties. Vacuum treatment not only improves the quality of the oil, but also prevents corrosion inside the transformer.
The PROMTECH company provides services at degassing of transformer oil throughout the Russian Federation at customer sites.
In the case of a critical condition of the oil, after its mechanical and vacuum treatment, the process of oil regeneration begins. Regeneration involves removing dissolved oxidation products and restoring the oil's antioxidant protection. One of the most effective methods is the use of adsorbents such as clay or specialized synthetic materials. These substances are able to absorb oxidized compounds and acids, thereby restoring the chemical characteristics of the oil.
In addition to adsorption, the method of hydrotritation is used - the restoration of oil by reacting it with hydrogen under high pressure and temperature. This process not only removes acids and other oxidized products, but also restores the molecular structure of the oil, thereby improving its physical and chemical properties.
Regeneration of transformer oilis the most complex process, but the results
The final stage in the cleaning and regeneration process is quality control of the treated oil. A number of laboratory tests are carried out, including measurements of dielectric constant, acid number and impurity levels. This is necessary to confirm that the oil meets the standards and requirements for transformer oils.
The processes of purification and regeneration of transformer oils require high precision and control at every stage. The quality and efficiency of processing directly affect the service life of the transformer and the safety of its operation. Therefore, it is important to use only proven methods and equipment, as well as conduct regular oil condition tests.
In conclusion, transformer oil cleaning and regeneration are critical processes that help ensure reliable operation of power systems. Modern technologies and methods make it possible not only to restore oil to its original characteristics, but also to significantly extend its service life, which ultimately helps to increase efficiency and save resources in the energy industry.
