<p><P>PROBLEM TO BE SOLVED: To provide a single-phase transformer and a distribution system using the same, wherein windings are prevented from deforming by making distribution of axial leakage magnetic flux uniform in peripheral directions of the windings and also making radius-directional electromagnetic force generated in case of secondary short-circuiting of the transformer uniform in the peripheral direction of the windings and by improving short-circuit resistive mechanical force accordingly. <P>SOLUTION: In a first iron core leg 1, primary winding 4a is wound on its outer peripheral side and a secondary winding 3a is wound on its inner peripheral side. In a second iron core leg 2, a primary winding 4b is wound on its inner peripheral side of and a secondary winding 3b is wound on its outer peripheral side, to the contrary with the arrangement of the first iron core leg 1. Further, the secondary winding 3a and primary winding 4a wound around the first iron core leg 1, and the secondary winding 3b and primary winding 4b wound around the second iron core leg 1 are opposite in winding directions between the two iron core legs 1 and 2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
