HELIUM CONTAINER FOR SUPERCONDUCTING ENERGY STORAGE DEVICE

PURPOSE:To resolve the problem on the difference of contraction amount and also realize a container-support structure, by coping with one directional (horizontal) contraction by means of a fold structure capable of relative displacement and the other directional (vertical) contraction by means of a slidable structure. CONSTITUTION:T-shaped stays 2 mounted on a helium container walls 1 are moved up and down inside rails 6 mounted on a coil system 3. And the helium container walls 1 are formed in wave shapes, with the helium container walls 1 themselves serving as fins in the horizontal direction, to perform expansion and contraction in the horizontal direction with these fins. Regardless of the difference of contraction amount both in the helium container walls 1 and in the coil system 3 to their relative displacement in the vertical direction, the helium container can be supported in the coil system. Expansion and contraction of the fins in the peripheral direction enable the difference of contraction amount to be absorbed and permit the helium container to be relatively displaced in the horizontal and vertical directions, and the stays mounted on the container walls are available for supporting the container.
