Abstract

PURPOSE:To prevent the change of tertiary voltage by a tap by forming the titled autotransformer lest the excitation of a core leg on which excitation winding is wound should be changed by the position of the tap. CONSTITUTION:Series winding 1 and shunt winding units 21A, 21B divided into two circuits are wound on at least one main leg 71 of a single-phase core, and shunt winding units 22A, 22B divided up and down, tap winding 4A, 4B divided into two circuits, the excitation winding 5 and tertiary winding 3 are wound on another main leg 72. One end of the series winding 1 is used as a high-tension line terminal v, and a medium-voltage line terminal u is drawn out to the other end while each medium-voltage line terminal side of separate shunt winding unit 21A, 21B is connected. The medium-voltage line terminal sides of the shunt winding units 22A, 22B are each connected in series with the neutral point sides of respective shunt winding unit 21A, 21B, and the tap winding 4A, 4B is connected to the neutral point sides of the shunt winding units 22A, 22B. The excitation winding 5 is connected between the terminals u, v.
