Abstract

PURPOSE:To prevent the change of tertiary voltage according to the position of a tap, and to obviate the reduction of the impedance of tertiary winding by winding exciting winding an the tertiary winding on the same side leg core. CONSTITUTION:Series winding 1 and shunt winding 2 are wound concentrically on a main leg 71, and tap winding 4, the tertiary winding 30 and the exciting winding 50 are wound on the side leg 70. The winding 4 is connected in series with the neutral point side of the winding 2, and the winding 50 is connected in parallel with the winding 2 and both terminals u, v of the series connecting circuit of the winding 4. The excitation of the core leg on which the winding 50 is wound doet not change according to the position of the tap because voltage between the terminals u, v is constant. The sectional area of the side leg on which the winding 30 is wound is the half of the main leg. Accordingly, impedance between the winding 50 and 30 in the case when the winding 30, 50 is wound on the side leg is quadrupled as compared to the case when the winding is wound on the main leg because induced voltage per one winding of the winding is halved.
