<p>PURPOSE:To increase a leakage impedance concerning a tertiary winding and to reduce a thickness of winding fastening plates, by shortening an axial length of the tertiary winding, and by passing lead wires through the spaces defined between the tertiary winding ends and the winding fastening plates respectively. CONSTITUTION:A shunt winding 2, a series winding 1 and a tap winding 3 each having an approximately equal winding height are wound on an iron core leg 5 in turn from the inside, and moreover a tertiary winding 41 having a lower winding height is wound thereon. The tertiary winding 41 is arrayed so that axial distance G1, G2 between respective ends of the winding 41 and respective ends of the tap winding 3 can become larger than a principal interval distance L2 between the tap winding 3 and the tertiary winding 41. Lead wires 8 of the tap winding 3 are passed through respective air gaps 8a between winding fastening plates 6, 7 and the tertiary winding 41, without passing through the winding fastening plate 6, 7 arrayed on the end sides of the windings.</p> |
