REACTOR CORE, AND REACTOR USING THE SAME

PROBLEM TO BE SOLVED: To facilitate assembly of a reactor excellent in DC superposition characteristics.SOLUTION: A reactor core includes first and second laminated cores having a plurality of leg parts which are integrally formed using a laminate of the magnetic steel sheet. In respective leg parts of the first and second laminated cores, a plurality of gaps which penetrate through parts of the leg parts in the lamination direction, extend in the core width direction, and cross magnetic paths of the leg parts, are provided so as to be arranged side by side along the magnetic path direction for each leg part in which the first laminated core and the second laminated core are opposite to each other. The plurality of leg parts in which the first laminated core and the second laminated core are opposed to each other are butted and joined to each other inside respective coils. 【課題】直流重畳特性に優れたリアクトルを容易に組み立てることができること。【解決手段】本発明の一態様であるリアクトルコアは、電磁鋼板の積層体を用いて一体的に形成される複数の脚部を有する第１および第２の積層コアを備える。第１および第２の積層コアの各脚部には、積層方向に脚部の一部を貫通し且つコア幅方向に延在して脚部の磁路を横切るギャップが、第１の積層コアと第２の積層コアとの対向する脚部毎に磁路方向に沿って複数並ぶように設けられる。第１の積層コアと第２の積層コアとの対向する複数の脚部同士は、各々コイル内において突き合わさって接合される。【選択図】図１
