Title:
静止誘導機器用積層鉄心
Document Type and Number:
Japanese Patent JP7092643
Kind Code:
B2
Abstract:
In a stacked core (1, 21) for a stationary induction apparatus according to an embodiment, joint surfaces where yoke portions (2, 3, 12, 22, 23) and leg portions (4, 5, 6, 11, 24, 25, 26) are joined have protrusions (8, 13) formed from a plurality of magnetic members (7), and recesses (9, 14) formed from a plurality of magnetic members alternately, and the yoke portions and the leg portions are configured to be butted in such a form that the protrusions and the recesses mesh with each other, sheet-like magnetic insulators (10, 15) are each disposed in a butt-joint portion between the protrusions and the recesses in such a form as to bend in a bellows shape along a butt line, and an air gap is provided, and in a relationship between the number of the stacked magnetic members forming each of the protrusions and the number of the stacked magnetic members forming each of the recesses, the number of the stacked magnetic members forming each of the protrusions is made smaller than the number of the stacked magnetic members forming each of the recesses corresponding to a thickness of the magnetic insulator.
