<p>PROBLEM TO BE SOLVED: To provide the winding of a stationary induction apparatus which is superior in conductor space factor and manufacturing workability and where a winding conductor hardly comes out of position. SOLUTION: A primary winding 23 of a transformer is composed of a square cylindrical winding part 25 which comprises conductors 25a each generally circular in cross section and continuously wound in layers and rows and a resin layer 26 which covers the winding part 25, wherein the conductors 25a are wound stacked up, sloping like logs as they are repeatedly wound made to be advanced, returned, and stepped up or down. In this constitution, the conductors 25a are wound in rows on the same layer and then wound stepping up or down, so that the frequency of the conductors 25a which are wound stepping up or down is lessened. Furthermore, an inclination angleθof the conductor 25a when the conductors 25a are wound stepping up or down becomes gradual, so that the winding conductors 25a hardly come out of position, even in a transformer of a large or intermediate capacitor.</p> |
