ABSTRACT:
A small size wound rotor transformer having a simple structure, wherein the primary winding (32) is mounted on the central portion of a bobbin (insulator) (2), and the first and second secondary windings (39, 41) are mounted at both sides of the primary winding (32). The lead wire (39a) of one end of the first secondary winding is connected to the secondary high tension terminal (24) of the first terminal unit (16), and the lead wire (32a) of one end of the primary winding (32) and the lead wire (39b) of an end portion of the winding at the side in contact with the primary winding (32) of the first secondary winding (39) are respectively connected to the corresponding primary input terminal (22) and the ground terminal (20) of the first terminal unit (16). The lead wire (41b) of one end of the second secondary winding (41) is connected to the secondary high tension terminal (30) of the second terminal unit, and the lead wire (32a) of the other end of the primary winding (32) and the lead wire (41a) of the end portion of the winding at the side in contact with the primary winding (32) of the second secondary winding (41) are respectively connected to the corresponding primary input terminal (28) and the ground terminal (26) of the second terminal unit (18). The core (42) is mounted on the bobbin (insulator) (2).
