A system for purifying oxidative materials of a transformer insulating oil in a live working state is provided to further enhance performance of a transformer and extend the service life of the transformer by automatically filtering moisture, carbon and impurities contained in an insulating oil charged in the transformer and cooling the filtered insulating oil, thereby preventing damage of the transformer due to dielectric breakdown. A system for purifying oxidative materials of a transformer insulating oil in a live working state comprises: a filtering pipe(200) of which both ends are perpendicularly connected to upper and lower portions of a transformer(100) respectively; a circulation pump(300) installed on an upper portion of the filtering pipe and operated when temperature of an insulating oil charged in the transformer is increased to a predetermined temperature; a mesh type impurity removing filter(400) installed on a lower portion of the filtering pipe to filter impurities contained in the insulating oil; a carbon filter(500) installed above the impurity removing filter to filter metal carbon and the like having relatively small particle sizes; and an adsorption filter(600) installed above the carbon filter to absorb moisture and supply filtered insulating oil to the transformer. The adsorption filter has a zeolite(610), a silica gel(620), a surfactant(630), and a filter paper(640) sequentially stacked therein.
