Abstract

A transformer windings structure comprising: an internal insulation cylinder (2A); an external insulation cylinder (2B); an inside vertical duct (4A); an outside vertical duct (4B); a plurality of horizontal ducts (5); a plurality of inside vertical spacer (9a) for forming the inside vertical duct (4A) and installed on the inner wall portion of the internal insulation cylinder (2A) in the vertical direction; a plurality of outside vertical spacer (9b) for forming the outside vertical duct (4B) and installed on the inner wall portion of the external insulation cylinder (2B) in the vertical direction; a plurality of horizontal spacers (10) for forming the plurality of horizontal ducts (5) and installed between the internal insulation cylinder (2A) and the external insulation cylinder (2B); a plurality of windings axially layered at a predetermined interval by the inside vertical duct spacers (9a) and the outside vertical duct spacers (9b), and installed between the internal insulation cylinder (2A) and the external insulation cylinder (2B); a plurality of baffles; a plurality of inlets and outlets; and a plurality of baffle regions formed between two adjacent baffles.
