INTERMEDIATE CONNECTION STRUCTURE FOR SUPERCONDUCTING CABLE

PROBLEM TO BE SOLVED: To provide an intermediate connection structure of a superconducting cable which is hard to be damaged even when a part connecting end parts of a cable core moves.SOLUTION: An intermediate connection structure of a superconducting cable connects superconducting cables provided with cable cores and a heat insulated pipe including an inner tubes housing the cable cores, and includes: a connection processing part connecting end parts of the cable core exposed from the inner tube; a guide part covering a range from an exposure part of one of the cable cores over to at least a part of the connection processing part so as to allow the connection processing part to move; an intermediate refrigerant tank which houses the range from the exposure part of one of the cable cores over to an exposure part of the other cable core via the connection processing part together with the guide part; and a pedestal part fixed to the intermediate refrigerant tank and supporting a prescribed position of the guide part. The guide part has: a fixed end connected to the inner tube; an open end movably supported with respect to the pedestal part; and an inner peripheral surface arranged flush with the inner peripheral surface of the end part of the inner tube.SELECTED DRAWING: Figure 1 【課題】ケーブルコアの端部同士を接続する部分が移動しても損傷し難い超電導ケーブルの中間接続構造を提供する。【解決手段】ケーブルコアと、ケーブルコアを収納する内管を含む断熱管とを備える超電導ケーブル同士を接続する超電導ケーブルの中間接続構造であって、内管から露出されたケーブルコアの端部同士を接続する接続処理部と、接続処理部の移動を許容するように、一方のケーブルコアの露出箇所から接続処理部の少なくとも一部に亘る範囲を覆うガイド部と、一方のケーブルコアの露出箇所から接続処理部を経て他方のケーブルコアの露出箇所に亘る範囲を、ガイド部を含めて収納する中間冷媒槽と、中間冷媒槽に固定され、ガイド部の所定位置を支持する台座部とを備え、ガイド部は、内管に接続される固定端と、台座部に対して移動可能に支持される開放端と、内管の端部の内周面に面一に配置される内周面とを有する超電導ケーブルの中間接続構造。【選択図】図１
