PURPOSE:To prevent the embrittlement of a wound core by aranging three of the wound cores, to which primary coils and secondary coils are set up and which consist of amorphous material, on the same axis and three-phase connecting each coil. CONSTITUTION:A single-phase transformer proper is constituted in such a manner that a plurality of coil spools 2, on which primary coils and secondary coils 3 are wound, are arranged on the circumferences of the wound cores 3a-3c consisting of amorphous material at regular intervals. A three-phase transformer proper is constituted in such a manner that these single-phase transformer propers are disposed on the same axis through insulating space plates 4a-4c and each single-phase transformer proper coil is thee-phase connected. According to such constitution, the brittle fracture of the core resulting from brittleness on the quality of material of the amorphous magnetic material can be prevented. |
