<p>PROBLEM TO BE SOLVED: To suppress increase in magnetic flux leakage or iron loss as much as possible by reducing junction in a flux path as much as possible when a magnetic flux flows from one leg to an adjacent leg, that is the problem of a conventional Y-shaped iron core, while taking advantages thereof.SOLUTION: An iron core for stationary induction apparatus includes three substantially U-shaped block iron cores, each having one leg and yoke formation parts at both ends of the leg. While these three block iron cores are arranged so that the legs are arranged at about 120 degrees around a predetermined point, the yoke formation parts are made to butt at each other.</p> |
