Publication number: 20170103843Abstract: Disclosed is a wound iron core (3) for a static apparatus in which magnetic paths in the inside of the wound iron core are subdivided to improve iron core characteristics. The iron core (3) is configured by using two or more kinds of magnetic materials (11 to 14) with different magnetic permeabilities to form laminated blocks with single plates or a plurality of laminated plates and by alternately arranging the laminated blocks with different magnetic permeabilities from the inner circumference. An iron core material (14) with large magnetic permeability out of iron core materials with different magnetic permeabilities is arranged on the inner circumference side. Further, when the iron core materials with different magnetic permeabilities are alternately arranged, the iron core materials (11) with the same magnetic permeability are configured to gradually change in thickness to ease an excessive magnetic flux density distribution in the iron core.Type: ApplicationFiled: December 22, 2016Publication date: April 13, 2017Inventors: Kenji NAKANOUE, Kazuyuki FUKUI, Hidemasa YAMAGUCHI, Kouhei SATOU, Tatsuhito AZEGAMI, Makoto SHINOHARA, Toshiaki TAKAHASHI, Tooru HONMA, Masanao KUWABARA, Toshiki SHIRAHATA, Yuuji SATOU, Manabu DOHI, Ryosuke MIKOSHIBA, Hiroyuki ENDOU

Patent number: 9514877Abstract: During the assembly process of an amorphous core transformer, when an offset has arisen between a coil and the amorphous core, and when an offset has arisen between the coil and the core due to a shock resulting from unloading or vibrations during transport, there has been the risk of breakage of an insulating member between an amorphous core and a coil, causing amorphous fragments to be scattered. The object of the present invention is to prevent scattering of amorphous fragments.Type: GrantFiled: June 14, 2013Date of Patent: December 6, 2016Assignee: Hitachi Industrial Equipment Systems Co., Ltd.Inventors: Toru Homma, Toshiaki Takahashi, Ryosuke Mikoshiba, Tatsunori Sato

Publication number: 20150348693Abstract: An amorphous core transformer is provided which is capable of effectively suppressing influences, fluctuation, displacement or the like of a coil caused by an electromagnetic mechanical force or the like. In an amorphous core transformer 100 including an amorphous core 101, a plurality of coils 102 in which the amorphous core 101 is inserted and a fixing metal frame 110 that assembles the coils 102 and the amorphous core 101, the inter-coil member 106 is interposed between the neighboring coils 102 and the inter-coil member 106 is positioned and held by a positioning member 107. Thus, it is possible to prevent the coils 102 from being deformed or displaced beyond the inter-coil member 106 and maintain the shape of the coils 102.Type: ApplicationFiled: June 10, 2015Publication date: December 3, 2015Inventors: Toshiaki TAKAHASHI, Hiroyuki ENDO, Ryosuke MIKOSHIBA, Tatsunori SATO

Patent number: 9041503Abstract: An amorphous transformer which includes an amorphous core formed of an amorphous material with a lap provided at an upper portion and allowed to stand in substantially a vertical direction while being supported at a core support member, and a coil which is fitted with the amorphous core. The core support member is formed by integrating a core support member for supporting a side surface of the amorphous core and a corner support member for supporting a corner portion of the core. The core support member is provided in substantially a vertical direction along at least one of the side surfaces of the core.Type: GrantFiled: September 30, 2013Date of Patent: May 26, 2015Assignee: Hitachi Industrial Equipment Systems Co., Ltd.Inventors: Ryosuke Mikoshiba, Hiroyuki Endo, Kenji Nakanoue, Toshiaki Takahashi, Tooru Honma
