Why is the transformer oil purification machine essential?
- Transformer oil is the main insulation and cooling medium of oil-immersed transformers. Its dielectric strength and chemical composition directly affect the performance of the transformer. If the oil contains a small amount of moisture and impurities, it will reduce the insulation strength; and the oil is in contact with oxygen, it is easy to oxidize and deteriorate at high temperatures. Therefore, the transformer oil purification machine should be carried out when the transformer is installed.
- To prevent the deterioration of the oil quality and the impact on the safe operation, the regular oil distribution samples for normal operation should be tested and analyzed, and the oil should be processed according to the analysis results. The inspection cycle of oil chemical supervision for distribution operation is specified to be at least once every three years.
- The usage of Yuneng's ZJA transformer oil purification machine improves the dielectric prosperities of your transformer insulation by reconditioning the oil under vacuum dehydration, degasification and filtration.
- The transformer oil purification plant is used for oil treatment, vacuum oil injection and cyclic hot oil drying in the installation and maintenance of big transformers.
- It features a high working vacuum, fast oil filtering and sound oil quality protection.
