Abstract
This invention relates to a pressure filtration and replacement device for transformer oil. The transformer is configured as an oil-immersed transformer. The device includes: oil drain and oil fill ports along a diagonal; a pressure filtration device connected to the oil drain port for filtering impurities from the old oil in the oil-immersed transformer, comprising: a base mechanism, a filter mechanism, a top sealing mechanism, and an adjusting mechanism sequentially and sealed from bottom to top; a recovery and replenishment storage tank sequentially connected to the oil outlet; the recovery storage tank comprising: a first tank body, an inlet, a recovery drain port, a breather pump, a first air seal valve, and a first monitoring mechanism; and the replenishment storage tank comprising: a second tank body, a replenishment port, a drain port, a top port, a second air seal valve, and a second monitoring mechanism. This transformer oil pressure filtration and replacement device of the invention filters the old oil, extending its service life; and replaces the old oil with new oil, thus protecting the transformer.
