Abstract

PURPOSE: To make the change of the total impedance lesser at changing the tap without forming a large-sized transformer by increasing impedance between the mediumvoltage winding and the low voltage ternary winding and making the electromagnetic coupling between the said windings sparse.
CONSTITUTION: The iron core has two main legs and two side legs. One mediumvoltage winding unit M2 and one high voltage winding unit H2 are provided between the main legs C1, C2. Also the low voltage ternary winding L and tap winding Ht are placed between the unit H2 and the leg C1, and the other mediumvoltage winding unit M1 and the other high voltage winding unit H1 are provided to the outside of the leg C1. In this way, a single-phase transformer is formed, the units M1 and M2 are connected with each other in parallel and are combined with the neutral point terminals U, O of the mediumvoltage line, the unit H1 and H2 are connected to each other in series, one end of its combination is connected to the terminal U of the high voltage line and the other end is done to the high voltage neutral point terminal O through the tap winding Ht. Since the low voltage ternary winding L is provided to the location adjacent to the high voltage winding unit H2, impedance can be increased without forming a large-sized transformer.
