[0047] A ribbon-shaped wire having a width W of 10 mm and a thickness t of 0.2 mm shown in FIG. 8 is tightly and solenoidally wound around a cylinder with a helical winding angle α of 88°, the cylinder having an outer diameter D of a cylindrical portion of 80 mm, The length L of 500 mm and the taper angle θ of 30° allow adjacent windings of the wire not to overlap each other. The wire was wound from one end of the cylindrical portion to the tapered portion at an angle of 88° to form a first layer, and was rewound in close contact with the tapered portion. The tape was then wound around the cylindrical portion at 88° in a direction opposite to that of the first layer, thereby forming a second layer. Therefore, the wire can be smoothly rewound to form the second layer while being in close contact with the tapered portion.

[0049] A ribbon-shaped wire having a width W of 10 mm and a thickness t of 0.2 mm shown in FIG. 10 is tightly and solenoidally wound around a cylinder with an outer diameter D of a cylindrical portion of 80 mm at a helical winding angle α of 88°. The length L of 500 mm and the taper angle θ1 of 10° and the taper angle θ2 of 30° allow adjacent windings of the wire not to overlap each other. The wire is wound from one end of the cylindrical portion to the first tapered portion at an angle of 88° to form the first layer, and is rewound in close contact with the first tapered portion and the second tapered portion, and then wrapped around the cylindrical Parts were wound at 88° in a direction opposite to that of the first layer, thereby forming a second layer. Therefore, the wire can be gently rewound in close contact with the tapered portion to form the second layer.

Abstract

A bobbin for a superconducting coil includes a cylindrical drum, and a tapered portion extending from each end of the drum. A superconducting wire or a precursor of the superconducting wire shaped like a tape is helically wound around the drum in multiple layers. The tapered portion has a tapered surface that is inclined at an arbitrary angle.

Description

technical field [0001] The present invention relates to a cylinder around which a tape-shaped superconducting wire is helically wound in multiple layers to form a superconducting coil, and to a solenoid coil formed by winding a tape-shaped superconducting wire in multiple layers around the cylinder. More particularly, the present invention relates to a device having a cylindrical drum and having a tape-shaped superconducting wire wound helically in multiple layers around the drum by a simple winding operation so as to form a solenoid coil and rewinding at both ends of the drum while reducing the The utility model relates to a deformed cylinder of small wires, and relates to a solenoid coil formed with a cylinder. Background technique [0002] As superconducting wires, metal superconducting wires such as NbTi or Nb3Sn and oxide superconducting wires such as bismuth oxide and yttrium oxide are known. The former metal superconducting wire rod is shaped into a thick tape with a...
