SUPERCONDUCTING MAGNETIC ENERGY STORAGE APPARATUS STRUCTURAL SUPPORT SYSTEM

摘要

A superconducting magnetic energy storage apparatuscomprising a cylindrical superconducting coil; a cylindrical coilcontainment vessel enclosing the coil and adapted to hold aliquid, such as liquefied helium; and a cylindrical vacuum vesselenclosing the coil containment vessel and located in a restrainingstructure having inner and outer circumferential walls and afloor; the apparatus being providing with horizontal compressionmembers between (1) the coil and the coil-containment vessel and(2) between the coil containment vessel and the vacuum vessel,compression bearing members between the vacuum vessel andthe restraining structure inner and outer walls, vertical supportmembers (1) between the coil bottom and the coil containmentvessel bottom and (2) between the coil containment vessel bottomand the vacuum vessel bottom, and external supports between thevacuum vessel bottom and the restraining structure floor,whereby the loads developed by thermal and magnetic energy changesin the apparatus can be accomodated and the structural integrityof the apparatus be maintained.
