WINDING CORE AND METHOD OF ASSEMBLING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an iron core for transformers that suppresses a decrease in an existence ratio of a magnetic material in the iron core, and is miniaturized and made light and reduces an excitation inrush current. SOLUTION: A plurality of loop-like magnetic blocks 11 are stacked in a radial direction. For each magnetic block, a plurality of grain-oriented silicon steel plates 12 are stacked in a radial direction, and a position of a cut section 13 formed between both the tips of the respective grain-oriented silicon steel plates is shifted for formation. Then, a non-magnetic sheet 16 is arranged continuous to the cut section. COPYRIGHT: (C)2011,JPO&INPIT
