Helium cooled high temperature superconducting member for high current high Tc superconducting current lead

摘要

Problem to be solved: to expose a helium cooled high temperature superconducting member for high current high temperature superconducting current lead.Stainless steel divertorBoth ends of the stainless steel divertor are vacuum brazed to the hot end copper head and the cold end copper head, respectivelyStainless steel divertorA recessed groove is provided on the outer peripheral surface of the high temperature end copper head and the low temperature end copper headA high temperature superconducting stack is mounted in the concave groove.A first layer of polyimide tape is placed outside the high temperature superconducting stackA measuring line member is passed through the hot end copper headA second layer of polyimide tape is provided outside the first layer of polyimide tapeA glass filament is covered and coveredThe sleeve support ring is soldered to the hot end copper headA sleeve for fitting the sleeve support ring outside the entire member is soldered.The present invention simplifies the process of processing and mounting by the user, and not only saves operation cost but also controls the temperature of the high temperature end of the high temperature superconducting member of the current lead at a low temperature of 65 K or less by heat transfer by cold helium gas at low temperature. The operation safety of the high temperature superconducting current lead wire can be effectively guaranteed.Diagram
