FIG. 2 shows a partial diagram of the superconducting power storage device.
Inside the liquid helium container 1 are superconductors 2 and
An Al alloy brick 3 is built in and immersed in liquid helium. 3 is insulated for each turn by an insulating plate 4 between the conductor turns, and vertically coupled with a tightening bolt 5 between the conductor turns. The internal pressure applied to the inner wall plate 1A of the liquid helium container 1 is balanced with the internal pressure applied to the outer wall plate 1B of the helium container 1 via the helium container reinforcing stay 6 and the Al alloy brick 3. The illustration of the helium container reinforcing stay 6 that engages with the inner wall plate 1A is omitted (it has the same structure as the helium container reinforcing stay 6 that engages with the outer wall plate 1B). The electromagnetic force generated by the current passing through the superconductor 2 is transmitted via the Al alloy brick 3 to the vertical support 7 forming a part of the helium container 1, and further transmitted to the rock via the heat insulating support member 8. Further, the helium container 1 is vacuum-insulated, and a radiation shield 9 is provided outside the helium container 1.

ろう付で接合される。 If the helium container 1 is made of a metal whose entire circumference is a conductor, heat generation due to the circulating current is unavoidable, so the container wall must be electrically insulated at at least one point on the circumference. In this structure, as shown in FIG. 3, ceramics 11 are used as an insulating material on one vertical section of the helium container 1. Note that the linear expansion coefficients of the helium container 1 and the ceramics 11 are generally quite different, so in order to alleviate thermal stress at low temperatures,
Between the helium container 1 and the ceramic 11 is a material 12 with an intermediate coefficient of linear expansion (e.g. Kovar).
Insert. The helium container 1 and Kovar 12 are joined by brazing.

FIG. 1 shows an embodiment of the present invention, and is a horizontal sectional view of the vicinity of a ceramic 11 used as an insulating material in one vertical section of a helium container 1. A relaxing material 12' (such as Kovar) having a coefficient of linear expansion between the helium container wall 1 and the ceramic 11 is inserted, but the shape of the relaxing material 12' is such that both end surfaces are concave. , helium container 1 and ceramics 11 are brazed. This relieves thermal stress in the dissimilar material joint.
