Claims (1)
ンクの内壁面に沿つて固定された複数の強磁性体
板からなり、前記誘導電器の巻線からの漏れ磁束
を吸収して前記タンクの漂遊負荷損を低減するも
のにおいて、前記強磁性体板が鉄粉と熱硬化性樹
脂からなる結合剤との混合物を加熱圧縮して所望
の形状の板状に形成してなる成形体からなること
を特徴とする誘導電器の磁気遮へい板。 It consists of a plurality of ferromagnetic plates fixed along the inner wall surface of a tank that houses the main body of an induction electric appliance together with an insulating medium, and absorbs leakage magnetic flux from the windings of the induction electric appliance to reduce stray load loss of the tank. In the ferromagnetic plate, the ferromagnetic plate is formed by heating and compressing a mixture of iron powder and a binder made of a thermosetting resin to form a plate of a desired shape. Magnetic shielding plate for induction electric equipment.
