As a kind of lubricating oil, transformer oil plays a vital role in the normal operation of transformers, such as insulation, cooling and lubrication. Its quality is directly related to the transformer's pressure resistance. There are mainly the following solutions for the filtration treatment of transformer oil:
During use, transformer oil will absorb a certain amount of water. If the water content is too high, it will affect the insulating effect. Therefore, we usually use a decompression vacuum oil filter to filter the oil. For 110kV-330kV transformers, a single-stage vacuum oil filter can be used for dehydration; when processing 110kV-500kV transformer oil, a two-stage vacuum oil filter can be used, and its Roots vacuum system makes the vacuuming effect better.
Impurities are one of the key factors affecting the quality of oil products, so it is necessary to ｓｅｌｅｃｔ filter elements of different precisions for treatment according to the quality of the oil products. In the selection of vacuum oil filters, the filtration accuracy can be as fine as 1 μm to meet the impurity removal needs of different oil products.
In order to remove gas from transformer oil, especially acetylene, we also use a vacuum oil filter for degassing, which has a significant degassing effect. The use of zl-js series two-stage vacuum oil filter can even reduce the acetylene content to zero.
This is also an important processing step. This can be achieved by a vacuum oil filter or a GIS vacuum unit. Both devices can effectively perform gas vacuum oil filling and other operations on the transformer box.
If you still have questions about the equipment selection required for oil treatment, you can refer to the functional characteristics of the oil filter to make a choice. At the same time, our SINO-NSH oil purifier manufacturer is also ready to provide you with professional technical solutions and guidance to help you better handle transformer oil.
