发明名称 MAGNETIC SHIELD STRUCTURE FOR AC POWER SINGLE WIRE CABLE
摘要 PROBLEM TO BE SOLVED: To provide a magnetic shield structure exhibiting excellent magnetic shield performance especially when the interval between the cables of respective phases is widened in a technology for shielding magnetic field being generated from an AC cable. SOLUTION: The magnetic shield structure for AC power single wire cable comprises a tubular soft magnetic body or a tubular soft magnetic body having polygonal cross-section wherein a cut is made in the soft magnetic body at a part on the circumference of cross-section perpendicular to the axis and the cut exists in the tubular surface like a slit in the axial direction. Preferably, the soft magnetic body is an electromagnetic steel plate, especially a directional electromagnetic steel plate. COPYRIGHT: (C)2006,JPO&NCIPI
