超電導ケーブル向け液体窒素循環冷却 ―鉄道き電による実証まで―

抄録

Introducing a superconducting cable is expected to reduce power loss. However, it needs cooling to maintain the superconducting state. In this paper, we outline the superconducting system which consists of superconducting cables and a cooling system. Subsequently, we report the examination of the efficient refrigerant circulation methods, the construction of the cooling system, and the results of the cooling tests on the railway site.
