Zusammenfassung:The invention relates to the technical field of transformer performance evaluation, and discloses a dry-type transformer pouring insulation layer anti-aging performance evaluation method and system, and the method comprises the steps: injecting a plurality of uniformly increasing test currents into a transformer pouring winding, and carrying out multiple aging period tests; the method comprises the following steps: acquiring the cycle number of the transformer cast winding when the highest amplitude of the partial discharge signal appears in multiple aging cycle tests, the number of the partial discharge signals in each aging cycle test, the highest amplitude of the partial discharge signals in each aging cycle test, and the hot-spot temperature of the winding in each aging cycle test; the method comprises the following steps: calculating an anti-aging performance evaluation factor according to a preset aging period test and an operation environment temperature in each aging period test, comparing the anti-ag
