The utility model discloses an interlayer insulation structure for a high-voltage winding of an oil immersed distribution transformer. The high-voltage winding comprises a plurality of layers of coils, all layers of coils are formed by winding wires, and interlayer insulation structures are arranged between every two adjacent layers of coils. Each interlayer insulation structure comprises insulating gluing paper tape, the insulating gluing paper tape is wound to the other end of the inner-layer coil of the corresponding two layers of coils from one end of the inner-layer coil in an overlapped winding mode, and the overlapped winding advance width of the insulating gluing paper tape is equal to the diameter of the wires. By means of the interlayer insulation structure, the structure is simple, it is guaranteed that insulation between every two adjacent layers of coils meets the electrical insulation requirement, and the anti-short-circuit capacity of the high-voltage winding is improved.
