The invention relates to a transformer iron core core-column pull plate fixed flow guide structure and a flow guide method thereof, and belongs to the technical field of large transformers. Accordingto the technical scheme, each iron core pull plate (1) and a hanging shaft fixing plate (5) are positioned on the two sides of an iron core web plate (4) respectively; a pull plate fixing plate (2) and an iron core lifting shaft (3) are both of a rectangular structure; a rectangular hole is formed in the iron core pull plate (1); the pull plate fixing plate (2) and the iron core lifting shaft (3)are arranged in the rectangular hole of the iron core pull plate (1) separately; the iron core pull plate (1) and the iron core lifting shaft (3) are fixed together through a metal bolt A (9); the iron core lifting shaft (3) and the hanging shaft fixing plate (5) are fixed together through a metal bolt B (10); and the iron core pull plates (1) of three phases of transformers are connected throughcopper bars (11). The transformer iron core core-column pull plate fixed flow guide structure has the beneficial effects that the overall mechanical strength of the iron core is met, and the problem that the iron core pull plate is overheated is solved.
