    • Magnetic flux in a magnetic flux distribution inside a wound iron core for a stationary apparatus is mal-distributed toward the inner periphery side where the magnetic path of a laminated magnetic steel sheet is short with respect to the total lamination thickness and magnetic resistance is small and the inner periphery side on which magnetic flux is concentrated has a high magnetic flux density and increased iron loss, and therefore magnetic steel sheets of different magnetic characteristics are disposed at an arbitrary lamination ratio to make uniform the magnetic flux distribution inside the same wound iron core. In order to make uniform the magnetic flux distribution inside the wound iron core for a stationary apparatus, such a structure is adopted that a magnetic steel sheet having a magnetic characteristic inferior to that on the outer periphery side is disposed on the inner periphery side having a shorter magnetic path and smaller magnetic resistance and a magnetic steel sheet having a magnetic characteristic superior to that on the inner periphery side is disposed on the outer periphery side having a longer magnetic path and greater magnetic resistance to thereby make uniform the magnetic flux distribution in a sectional area of the iron core.
    • 用于静止装置的绕铁心内的磁通量分布中的磁通量相对于总层压厚度和层叠电磁钢板的磁路短而磁性分布不均匀,磁阻小 磁通集中的内周侧具有高的磁通密度和铁损的增加,因此磁特性不同的电磁钢板以任意的层叠比设置,使得在相同绕线铁心内部的磁通分布均匀 。 为了使静止装置的绕铁心内的磁通分布均匀,采用这样的结构,即具有比外周侧低的磁特性的磁性钢板设置在具有 较短的磁路和较小的磁阻以及具有优于内周侧的磁特性的磁性钢板设置在具有较长磁路和较大磁阻的外周侧上,从而使磁通分布均匀 铁芯截面积。
