Abstract

PURPOSE:To contrive the reduction in size of the single-phase transformer by dividing the transformer into a plurality of unit transformers, arranging high, low voltage and shield electrodes on the same shaft, and connecting the oil paths between the electrodes using oil lead wires segmented by insulating barriers to reduce the number of ducts. CONSTITUTION:A single-phase transformer is divided into a plurality of unit transformers A, B, an insulating coating 12 is coated on the outer periphery of a high voltage lead electrode 16 passed through the center, and a plurality of cylindrical insulating barriers 13 are provided on the outside thereof to dispose middle voltate lead electrodes 17 on the same shaft. Further, a grounding shield electrode 18 is provided through a plurality of cylindrical insulating barriers 23 on the same shaft as the high voltage, low voltage lead electrodes 16, 17 on the outside thereof. Then, high voltage lead wires 6 and middle voltage lead wires 7 of high and middle voltage windings 2 and 3, respectively are connected to high and middle lead electrodes 16 and 17, respectively to dispose the electrode 18 at the opening of the duct 15 and to expand it in flared state to alleviate the concentration of the electric field in order to contrive the improvement in the reduction of the number of the ducts 15 and the insulation of the lead wires.
