The transformer oil filter adopts the oil-water separation technology combined with thin film evaporation and drying, sets the vacuum pumping speed and heating power matched with the flow, and is equipped with degassing elements, so that the machine has good dehydration function. The insulating oil was treated at room temperature, and its performance indexes all exceeded the standard requirements. The composite microporous filtration technology is adopted, which has strong suction capacity and high filtration precision. Small volume, reliable operation, easy to move, especially suitable for field treatment of insulating oil.
The transformer oil filter adopts three-dimensional flash evaporation and microgram technology, and adopts the removal technology of combination of mesh filtration and molecular adsorption. Its efficiency is 5-8 times that of ordinary vacuum filter, without any consumables, and the energy consumption is very low.
Working principle of transformer oil filter
When the transformer oil filter works, the oil enters into the prefilter under the action of the internal and external pressure difference, and the large particle impurities are filtered. After the oil is heated to a special personalized vacuum separator by multiple infrared rays, the fog first forms in the vacuum separator, forming a film, and the contact area of the vacuum expands hundreds of times. The water in the oil is high heat, high vacuum and large surface. Under the condition of rapid evaporation and discharge of the vacuum system, the pumping speed is high High degree.
The steam discharged from the upper part of the vacuum separator is first cooled and dehumidified by the condenser, and then cooled in the cooler. The condensate is discharged into the water storage device first, and then discharged into the air by the vacuum pump after secondary condensation and dehumidification.
The dry oil in vacuum separator is evaporated and dehydrated by vacuum, and then it is raised from negative pressure to positive pressure by oil pump. After filtration, the purified oil is discharged from the outlet to complete the whole oil purification process.
