Summary: | The utility model provides a winding structure of an on-load voltage regulation distribution transformer, which comprises a low-voltage winding and a high-voltage winding, the high-voltage winding comprises Q layers of coils, the Q layers of coils are formed by continuously winding conducting wires, from the outermost layer of coil, tapping taps are led out from the two ends of each layer of coil and are led out along the axial direction of the high-voltage winding, the total number of turns of the high-voltage winding is equal to n1 + (P-1) * n2 = Q * n3, n2 is equal to n3, n1 is the number of turns of the basic section, P is the number of tapping taps, n2 is the number of turns of the tapping section, n3 is the number of turns of each layer of coil, and both P and Q are positive integers. Correspondingly, the utility model further provides a distribution transformer. The winding structure can realize ampere-turn balance, so that the sudden short circuit resistance of the transformer is improved.
