を超電導線４間に充填含浸させる。 To briefly explain the manufacturing procedure of this coil, a coil winding frame 1, a superconducting wire 4 covered with insulation such as glass fiber, etc.
The superconducting wire 4 is wound in multiple layers around the outer periphery of the reinforcing wire 5 via an insulating material 3.
radially inward, and then, as shown by the arrow, the impregnating agent 6 is passed through the gap between the reinforcing wires 5.

つた。
Conventionally, superconducting coils have been manufactured in this way, but since a single wire type is used as the reinforcing wire 5, if it is wound tightly, the path for filling the coil with the impregnating agent 6 will be blocked. The impregnating agent 6 cannot be sufficiently distributed throughout the coil,
On the other hand, if the impregnating agent 6 is made easier to penetrate into the coil,
There was a problem in that the tightening force of the reinforcing wire 5 was insufficient, and in any case, it was difficult to fix the superconducting wire 4 firmly enough to prevent the above-mentioned positional shift.
この考案は上記の問題点を解決するためになさ

実質上無く、従来に比し高精度で通常容量低下の
少ない超電導コイルを得ることを目的とする。 This idea was made to solve the above problems, and the aim is to obtain a superconducting coil with virtually no risk of misalignment of the superconducting wire, higher precision, and less loss of capacity than conventional ones. do.

In order to achieve the above object, this invention uses non-formed stranded wire as the reinforcing wire, and the winding layer of the reinforcing wire has a number of meandering resin-filled parts reaching from the outer periphery to the inner periphery and forming impregnated resin passages. The structure is as follows.

FIG. 1 is a half-sectional view showing an embodiment of this invention. In the figure, 1 to 4 and 6 are the same as those in FIG. The difference is that in the example, a three-strand twist is used.
この構成においては、超電導コイルの製作手順

る。 In this configuration, the manufacturing procedure of the superconducting coil is the same as the conventional one, but since the reinforcing wire 7 is made of stranded wire that becomes non-aligned winding when it is wound in multiple layers, the outer periphery of the reinforcing wire 7 is Since a gap is secured in a meandering manner from the surface side to the inner circumference side, this gap is used as the filling path A, and the entire inside of the coil is sufficiently impregnated with the impregnating agent 6, and the reinforcing wire layer after impregnation and solidification is It has a meandering structure with numerous gaps (filled with resin) that reach the inner periphery and become impregnated resin passages.

従して収縮し、締付けが弛む恐れは無い。 Furthermore, since stranded wire has a significantly higher elongation rate when winding tension is applied than solid wire, even if large thermal contraction occurs in superconducting wire 4 during the cryogenic cooling process after coil formation, reinforcing wire 7 It fully follows the contraction and contracts, so there is no risk of the tightening loosening.
なお、上記実施例では、補強線材７として撚線

As explained above, by using stranded wire as the reinforcing wire, the present invention can sufficiently fill the entire coil with the impregnating agent without sacrificing the tightening force of the reinforcing wire. Since the turns can be fixed more firmly than in the past, displacement of the superconducting wire that occurs after the coil is energized can be virtually eliminated, making it possible to obtain a superconducting coil with high precision and less loss of normal capacity.
