Problems solved by technology

[0002] At present, the solenoid-type superconducting ROEBEL winding structure directly winds the superconducting cable on the liner on which the superconducting cable is wound. Under the impact of a large current, the displacement or vibration of the superconducting cable is easy to occur. and other phenomena, and it is easy to cause the liner to be damaged by the impact of large electromagnetic force. At the same time, because the superconducting cables directly wound on the liner are tightly wound, there is no gap between the superconducting cables, and the superconducting wire The circulation of liquid nitrogen between the cables is hindered, resulting in inefficient cooling of the winding structure

Description

technical field [0001] The invention relates to the technical field of superconducting electric power application, and more specifically relates to a multilayer solenoid superconducting ROEBEL winding structure. Background technique [0002] At present, the solenoid-type superconducting ROEBEL winding structure directly winds the superconducting cable on the liner on which the superconducting cable is wound. Under the impact of a large current, the displacement or vibration of the superconducting cable is easy to occur. and other phenomena, and it is easy to cause the liner to be damaged by the impact of large electromagnetic force. At the same time, because the superconducting cables directly wound on the liner are tightly wound, there is no gap between the superconducting cables, and the superconducting wire The circulation of liquid nitrogen between the cables is hindered, resulting in inefficient cooling of the winding structure. [0003] Therefore, how to provide a sol...
