[0025] As a further implementation of the present invention, the positioning block 63 slides in the ventilation positioning groove 512, the horizontal square through hole in the positioning block 63 has the same area as the square through hole on the horizontal plane of the ventilation positioning groove 512, and the positioning block 63 is interconnected with the partition plate 61, which can improve the heat dissipation performance of the transformer winding;

[0026] As a further implementation of the present invention, a plurality of vent holes 62 are symmetrically provided on both sides of the partition plate 61, and a cavity is provided inside the partition plate 61. The connecting slide plate 642 slides inside the partition plate 61, which can improve the heat dissipation effect of the accumulated heat between the coils 52.

[0027] As a further implementation of the present invention, two slide bars 641 are symmetrically provided on the inner side of the partition plate 61. The slide bars 641 and the sliders 643 slide in the slide grooves 513. The length of the slide bars 641 is much greater than the length of the positioning block 63, so as to facilitate the adjustment of the position of the partition plate 61.

During the use of the reduction furnace polysilicon transformer with the low-voltage winding 5 structure, the ventilation positioning groove 512 opened on the inner side of the cylinder 511 is connected with the cavity inside the partition plate 61 in sequence through the hole opened on the inner side of the positioning block 63, and a number of ventilation holes 62 are opened on the inner side of the partition plate 61, so that the partition plate 61 can quickly conduct the heat accumulated between the coils 52, thereby ensuring that the reduction furnace polysilicon transformer has an efficient and stable operation effect, and ensuring that the radial split structure of the winding of the reduction furnace polysilicon transformer has a better heat dissipation performance.
