Mechanical impurities in insulating oil refer to precipitates and suspended substances that are insoluble in solvents, such as sand, iron particles, insulating fiber fragments, free carbon, etc. However, the impurities measured by the current method also include some organic components that are insoluble in solvents , Such as carbides formed after oxidation.
Impurities come from the transportation and storage of insulating oil. If the oil container is not cleaned or the container is not tight, impurities such as rust or dust will be mixed into the insulating oil. When filtering and regenerating insulating oil, there is also an opportunity to invade the oil, such as organic fibers can fall off from the filter paper; solid insulating materials continue to deteriorate and fall off during use, and are mixed into the operating transformer oil; the new oil refining process may also Mixed with white rabbits, impurities in additives and other mechanical impurities.
