Processing system for lowering dielectric loss value of transformer oil

The utility model discloses a processing system for lowering the dielectric loss value of transformer oil. The processing system comprises a vacuum oil filter machine, and an oil cleaning tank, an oil pump and a filter which are sequentially connected through a pipeline in a circulation manner, wherein the vacuum oil filter machine and the clean oil tank are separately communicated. The processing system is characterized by also comprising a heater and an oil dielectric loss processing tank, wherein the heater and the oil dielectric loss processing tank are sequentially connected in series between the oil pump and the filter. According to the processing system, the heater is used for heating the transformer oil entering the oil dielectric loss processing tank, to improve the adsorption and processing capacity, on pollutants in the transformer oil, of the oil dielectric loss processing tank; the oil dielectric loss processing tank performs processing on the passing transformer oil, thorough cleaning and adsorption on an oil pipeline are completed, the pollution of the oil pipeline is effectively solved, the dielectric loss value of the transformer oil is lowered, and the transformer oil is enabled to be transported to a transformer from the oil cleaning tank safely and reliably.
