  • Amorphous core transformer
    Patent number: 9601255
    Abstract: In an amorphous core transformer, an amorphous core is constructed such that, when a plurality of kinds of amorphous magnetic strips having different widths are arranged in abutting relation and laminated, the amorphous magnetic strips are alternated in arrangement for lamination so that abutting surfaces of the arranged and laminated amorphous magnetic strips are displaced with respect to one another. Thus, hours of wrapping work are drastically reduced and working efficiency is improved.
    Type: Grant
    Filed: August 8, 2012
    Date of Patent: March 21, 2017
    Assignee: Hitachi Industrial Equipment Systems Co., Ltd.
    Inventors: Keisuke Kubota, Toshiki Shirahata, Junji Ono, Yoetsu Shiina
  • Transformer, amorphous transformer and method of manufacturing the transformer
    Patent number: 9230729
    Abstract: A transformer wherein the upper portions of cores are supported by a first supporting member disposed on first end surfaces of the upper portions of the cores, and a second supporting member disposed on second end surfaces of the upper portions of the cores, the first and second supporting members extend in the direction perpendicular to the faces of a magnetic material, and the cores are interposed between the first upper core supporting member and the second upper core supporting member; the first and second upper core supporting members are provided with hooks, the hooks of the first supporting member extending toward the second supporting member and the hooks of the second supporting member extending toward the first supporting member; bridging members are disposed on the opposing pairs of the hooks of the first and second upper core supporting members; and the cores are supported by the bridging members.
