Abstract

PURPOSE:To enable the constitution of the on-load tap changing transformer even if the number of turns of the main winding and the number of turns of the tap winding are not coincided by a method wherein one of three main windings is made as two parallel windings at up and down, one end is connected to the line terminal and other end is connected to other main winding respectively in series, and other ends of two main windings are connected to the top windings in series relation. CONSTITUTION:Either of main windings wound around respective core main legs 131-133, for example, a main winding 141 wound around the main leg 131 is made to be two parallel constitution at up and down, respective one ends are connected to a line side terminal and other ends are connected to one ends of main windings 142, 143 in series relation respectively to constitute two parallel circuit. On the other hand in the on-load voltage regulator 2, tap windings 241-242 are consisted of two group windings connectable in parallel with each other, and two group on- load tap changers consisted of tap selectors 251, 252 and change-over switches 271, 272 are arranged respectively to these two group windings. By this way, even if the number of turns of the main winding and the number of turns of the tap winding are not coincided, two group windings can easily be constituted on the whole.
