Abstract
PURPOSE: To reduce the magnetic unbalance between high and low main windings by arranging high pressure voltage tap windings between two divided high voltage main windings geometrically or coaxially with these windings.
CONSTITUTION: The high voltage tap winding 2 is arranged coaxially with the high voltage main windings and geometrically near the center of the high voltage windings in an arrangement of the first high voltage main winding 1A, high voltage tap winding 2, and the second main winding 1B. Electrically, the U- and W-phases high voltage tap winding 2 is connected to the Z terminal. The V phase is directly connected to the V terminal in the order of U - 1A - X, ... Z4 - 2 - Z. The tap of the two high voltage tap windings located at the same line is switched by a common load tap changeover unit. This permits the magnetic unbalance between the high and low windings to comparatively be reduced and a two phase load tap changeover unit to be shared by one unit. As a whole, the load tap of a three-phase triangular connection is enabled using two load tap changeover units.
