PURPOSE:To simplify structure and to reduce the using amount of an insulator as well by a method wherein a tap winding unit is positioned between a line side winding unit and an other terminal side winding unit. CONSTITUTION:A high-voltage side winding H is formed by three pieces of a line side winding unit 2a positioned in the axis direction, an other terminal side winding unit 1a, and a tap winding unit 3a having a tap winding at a main winding. The tap winding unit 3a is positioned between the line side winding unit 2a and the other terminal side winding unit 1a. A voltage can be changed by commonly using the tap winding unit 3a by forming in this way and one tap changer is enough to simplify structure. A shorter one corresponding to the width of each winding unit is acceptable as insulators between each winding unit. Therefore, the using amount of an insulator can be decreased. |
