Abstract

PURPOSE:To simplify and miniaturize the construction of the subject transformer by a method wherein a flowing wiring circuit is constituted of a narrow-stripped wiring circuit having the width proportionate to the overall heigh of the corresponding wiring circuit when a concertric circulating current flowing wiring circuit is wound around the tapped corresponding wiring circuit which constitutes the main three-phase side wiring circuit of a Scott connection transformer. CONSTITUTION:In order to cancel the current on the T-pedestal three-phase side wiring circuit 3 flowing to the main three-phase side wiring circuit 2, which is the corresponding wiring circuit wound around the outer circumference of a core 1, a main pedestal single-phase side wiring circuit 21, which is the circulating current flowing wiring circuit concentric to the wiring circuit 1, is wound around and at the same time, a T-pedestal single-phase side wiring circuit 5 is also wound around. In this constitution, the wiring circuit 21 is constituted of a narrow-stripped wiring circuit corresponding to the overall height measurements of the wiring circuit 2, and is wound around as many time as necessary. In this constitution, the current coming from the wiring circuit 3 and flowing to the center point M of the wiring circuit 2 is branched off to the side of terminals U and W, located at the end section of the wiring circuit 2, respectively and the direction of the current is reversed at the boundary point M. Accordingly, the current on the wiring circuit 21, which works to cancel the above current, also flows to the reverse direction, and the circulating current runs on the wiring circuit 21.
