LAMINATED HIGH TEMPERATURE SUPPERCONDUCTOR WIRE STRUCTURE AND MANUFACTURING METHOD THEREOF

摘要

Disclosed are a laminated high-temperature superconductive wire material and a method for manufacturing the same. The laminated high-temperature superconductive wire comprises: a first superconductive thin film wire material including a metal substrate, a buffer layer and a superconductive layer; a second superconductive wire thin film wire material including a metal substrate, a buffer layer and a superconductive layer, and arranged on the first superconductive thin film wire material with an interval; a metal internal stabilization layer disposed between the first and second superconductive thin film wire materials; a metal reinforcement including a first reinforcing layer arranged on the lower side of the first superconductive thin film wire material and a second reinforcing layer arranged on the upper side of the second superconductive thin film wire material; and a solder member formed to surround the peripheries of the first and second superconductive thin film wire materials, the metal internal stabilization layer and the metal reinforcement. Thereby, a threshold current of the laminated high-temperature superconductive wire material may be increased by the arrangement of the multiple superconductive thin film wire materials, and the metal internal stabilization layer arranged between the multiple superconductive thin film wire materials may bypass a transient current stably. In addition, the metal reinforcing layers disposed on the metal substrates of the superconductive thin film wire materials may increase mechanical strength.
