層導体に予め圧縮予荷重を負荷する必要がある。(Problems to be Solved by the Invention) However, the above-described conventional technology can cope with deformation in a tangential direction, but is insufficient in deformation in a radial direction. In particular, there has been no method for quantitatively applying an accurate surface pressure. In general, when the laminated conductor 2 (superconducting wire) is minute, even if deformed, quenching (a phenomenon of transition from a superconducting state to a normal conducting state) occurs, thereby lowering the reliability as a generator. In order to prevent even minute deformation, it is necessary to apply an accurate surface pressure. For this purpose, it is necessary to apply a compression preload to the laminated conductor in advance.

予荷重を負荷できる。Hereinafter, the operation of the present embodiment will be described. Laminated conductor 2
The rigidity varies depending on the superconducting wire, the wire insulation, the impregnated resin, the stranded wire method, etc., which constitute the laminated conductor 2, and the rigidity also varies as the thickness of the laminated conductor 2 changes. Such rigidity, stress relaxation after load application, heat shrinkage difference with the supporting structure at cool down, centrifugal force at rated rotation, range force at excitation, etc. The compression preload must be adjusted sufficiently to accommodate the change.

さ寸法を調整すればよいことになる。As an example, FIG. 4 shows the response to stress relaxation (creep deformation) that occurs after applying a compressive preload to the laminated conductor 2. When a compressive preload is first applied to the laminated conductor 2, a load-displacement curve as shown by a line L1 is shown. After a predetermined time has passed after the compressive preload is applied, creep deformation is determined, and the final More specifically, it shows a load-displacement curve after relaxation as indicated by a line L2. Therefore, in anticipation of the beginning required compressive load P A be held at the point A, resulting in down to over time point B (load P B). Thus, if the stress relaxation after the compressive load is anticipated and brought to the point C in advance, the point A which gives the necessary compressive load PA by the occurrence of the stress relaxation is secured. Thus compressive preload is point C, i.e. so that the conductor thickness is t c, it is sufficient to adjust the taper angle and the thickness of the wedge 34.

That is, each of the wedges 34 and 35 can be divided in the axial direction (see FIG. 2) to have an arbitrary length, and the laminated conductor 2 can be uniformly compressed not only in the linear portion but also in the corner portion.

As in the second embodiment shown in FIG.
Not only by making the side spacer 24 tapered,
The tangential (circumferential) surface pressure load can be performed simultaneously with the radial surface pressure load. The tangential surface pressure can be obtained by adjusting the taper angle of the side spacer 24. For this adjustment, for example, in order to apply an accurate compression preload in consideration of stress relaxation, the fourth
A load-displacement diagram as shown in the figure is obtained by applying a load to the laminated conductor 2 in a tangential direction by a test in advance, and a necessary compressive load can be accurately applied. By applying a surface pressure load simultaneously from both the radial direction and the tangential direction, a synergistic effect based on the Poisson's ratio can be obtained, and the deformation of the laminated conductor can be more strongly prevented.
