Transformer structure high in short circuit resistance

The invention relates to a transformer structure high in short circuit resistance, and belongs to the technical field of transformers. According to the technical scheme, the structure comprises a transformer iron core column (21), auxiliary supporting bars (22), a low-voltage winding (23), supporting bars (24) and inner auxiliary supporting bars (25), wherein the auxiliary supporting bars are arranged at the edges of iron core stack pieces on the cross section of the transformer iron core column, and therefore the cross section of the transformer iron core column can be more similar to a circle; the multiple supporting bars are evenly distributed on the low-voltage winding in the circumferential direction, the inner auxiliary supporting bars are arranged between every two supporting bars and arranged on the inner circumference of the low-voltage winding, and stress on the low-voltage winding is balanced to the inner auxiliary supporting bars. The transformer structure has the advantage that a traditional tran
