摘要
The invention relates to a method of manufacturing a transformer with a triangular core structure and a transformer with triangular core structure. Laminations (2) are cut in the shape of trapeziums with predetermined sizes from a high permeability sheet material (1) and stacked to form the four sides of three rectangle frames (7) to obtain a triangular core structure with a bottom yoke (4), top yoke (5) and three vertical limbs (6). The three vertices of said bottom yoke (4) and top yoke (5) are connected. The bottom yoke (4) is clamped with bottom clamps (8). The top yoke (5) is removed and three wound coils (10) comprising primary and secondary windings are introduced through each vertical limb (6). The top yoke (5) is placed and clamped with top clamps (9). The bottom clamps (8) and top clamps (9) are clamped by tie rods (11) to obtain a transformer with a triangular core structure.
