Interlayer insulating oil duct of oil-immersed transformer

The utility model relates to the technical field of transformer accessories, in particular to an oil-immersed transformer interlayer insulating oil duct which comprises a rectangular pipe, a plurality of outer guide inclined blocks are fixed on the outer side walls of two short edges of the rectangular pipe at equal intervals, and a plurality of inner guide inclined blocks are fixed on the inner side walls of the two short edges of the rectangular pipe at equal intervals. By arranging the outer guide inclined block and the inner guide inclined block, a continuous guide structure is formed between the two windings of the oil-immersed transformer, so that the transformer oil is ensured to flow in a specified direction, the dispersity of the transformer oil is reduced, and the replacement efficiency of the internal transformer oil is improved. According to the utility model, the arc-shaped groove is provided with the guide block in a matched manner, the guide block is in sliding insertion connection with the arc
