Abstract
The present invention relates to a structure of a high temperature superconductive double helix current lead wire, which belongs to the technical filed of high temperature superconduction. The present invention is characterized in that the structure of the lead wire comprises a double helix groove barrel, a high temperature superconductive current inlet wire and a high temperature superconductive current outlet wire, wherein the double helix groove barrel is made of epoxy resin, and the cylindrical surface forms a double helix groove ditch shape; the high temperature superconductive current inlet and outlet wires both made of Bi-2223/Ag materials are wound on the double helix groove barrel orderly at intervals, and are both connected with a superconductive energy storage magnet arranged in liquid helium. The double helix structure can effectively extend the length of the high temperature superconductive current inlet and outlet wires, so that the heat resistance of the lead wire is increased, and the heat leakage to a low temperature cooling magnet system is decreased.
