PURPOSE:To withstand a large electromagnetic force, by constituting a divided-type coil supporting frame by incorporating a plurality of frame bodies in the plurality of directions, providing spacers with wedges in the supporting frame, and tightly fastening conductors to the supporting frame. CONSTITUTION:A supporting frame 2, which is divided into three portions, is provided with a flange portion, and is constituted by two frame bodies 23a and 23b which have the same configuration, and a lid-shaped frame body 22. A spacer 8 is inserted in the collar portion formed at the ends of the frame bodies 23a and 23b, and both frame bodies are fastened by a bolt 6 and a nut 7. The lid-shaped frame body 22 is fastened to the other end of the frame body 23 by bolts 5, thereby one body is constituted. Insulators 12 between the layers and insulators 13 for the ground are provided for a conductor 11. When it is enclosed in the supporting frame 2, wedge-shaped spacers are put in after the coil with one or two turns is inserted, and both spacers are connected in a tapered shape. In the constitution, sufficient rigidity can be maintained against a large electromagnetic force. |
