PURPOSE:To enable to uniformly rise the temperature of a stationary induction electric device by leading the starting and finishing ends of a coil at the same side, dividing at least one layer radially into two layers, winding the conductor of one layer in a forward direction and winding the conductor of the other layer in a returning direction. CONSTITUTION:A secondary coil 13 associated with a primary coil 10 in a core 9 is composed of four conductors in two stage and two rows and a specific layer 12 wound in a general wound layer 11 and one stage, four rows. The layer 12 is radially divided into two layers, one layer (left side) is wound from lower side to upper side in a forward direction, and the other layer (right side) is wound from upper side to lower side in a returning direction. The leading wires are led from the upper side together with starting end lead 14 and finishing end lead 15. In this manner, the lead wires can be led from the same side, thereby improving the space factor of the coil, uniforming rising the temperatures of the respective layers and reducing the weight. |
