A device for restraining circulation of transformer iron core structural members relates to the technical field of transformers and comprises an iron core formed by overlapping a plurality of silicon steel sheets, iron core structural members used for fixing the iron core are arranged on the front side and the rear side of the iron core, a coil is wound on the iron core, a shell is wrapped on the iron core, a voltage regulating lead is connected to the rear side of the iron core, and the voltage regulating lead is connected to the shell. The silicon steel sheet located on the outermost layer of the rear side of the iron core is replaced by a copper sheet, a plurality of stand columns matched with the silicon steel sheet in structure are arranged in the middle of the copper sheet, a plurality of strip-shaped through holes used for reducing eddy current are formed in the stand columns at intervals in the length direction of the stand columns, and a layer of insulation spacer is arranged between the copper sheet
