330KV transformer body structure and assembling method thereof

The invention belongs to the field of transformer manufacturing, and relates to a 330KV transformer body structure and an assembly method thereof. In the transformer body structure, a transformer winding comprises a voltage stabilizing coil, a low-voltage coil, a high-voltage coil and a voltage regulating coil from inside to outside, the low-voltage coil comprises a first low-voltage coil and a second low-voltage coil, and the first low-voltage coil and the second low-voltage coil are of a radial split structure. The insulating paper cylinder is positioned between the transformer iron core and the voltage-stabilizing coil, between the voltage-stabilizing coil and the low-voltage coil, and between the low-voltage coil I and the low-voltage coil II; the transformer insulating sleeve is positioned between the low-voltage coil and the high-voltage coil, and between the high-voltage coil and the voltage-regulating coil; the head end of the high-voltage coil adopts a middle radial wire outlet structure, and the tai
