Liquid helium immersion low temperature superconducting member for high current high Tc superconducting current lead

摘要

Problem to be solved: to expose a liquid helium immersion low temperature superconducting member for high current high temperature superconducting current lead.A low temperature superconducting copper head (3) is provided.The one end of the low temperature superconducting copper head (3) has a circular cross-section;An engaging groove (6) is disposed on the circumferential surface thereof.A low temperature superconducting line (2) is anchored to the locking groove (6), respectively.And is press fitted by a high temperature superconducting stackThe cross section of the other end of the low temperature superconducting copper headA concave groove (7) is provided on both sides thereofAn extended portion of the low temperature superconducting wire (2) is engaged in the concave groove (7), respectivelyA liquid helium immersion type low temperature superconducting member for high current high temperature superconducting current lead which is pressed and fixed by a stainless steel cover (4) and constitutes a low temperature superconducting joint part.The proposed design is reasonable in structural design, and the three parts of the low temperature end of the high temperature superconducting part, the low temperature superconducting part and the low temperature superconducting joint are integrated, and the contact resistance is lowered, and the processing and mounting process by the user are simplified, and the operation cost is saved. The operation safety of the high-temperature superconducting current lead can be effectively guaranteed.Diagram
