Description
Technical Field
The invention relates to the technical field of superconducting magnet winding, in particular to a jointless multi-cake coil winding machine.
Background
The second generation high temperature superconducting tape based on rare earth barium copper oxide (REBCO, RE is rare earth element) material has the advantages of high critical temperature, strong current carrying capacity, low operation cost and the like, thus having great application potential in the aspect of developing superconducting magnets. The second generation high temperature superconducting tape generally adopts a double-pancake winding method to form a modularized double-pancake coil, and then the double-pancake coil is connected by a connector to form the superconducting magnet.
When the superconducting tapes are connected with each other by their metal protective layers, the joints have electric resistance. When the superconducting magnet is electrified to operate, a large amount of heat energy can be generated at the joint, the stable operation of the magnet is influenced, and even the magnet is quenched or damaged. When the superconducting tapes are connected with each other through the superconducting layers, a superconducting joint with zero resistance is formed. The superconducting layer of the second-generation high-temperature superconducting strip is made of ceramic materials, the thickness of the superconducting layer is in the micron order, and the superconducting layer has high current-carrying capacity only under the condition of biaxial texture, so that the superconducting joint is very difficult to prepare, and the process is unstable; secondly, the superconducting layer connection interface of the superconducting joint is extremely fragile, making it difficult to operate in a strong magnetic field environment.
In view of the above, it is necessary to avoid using joints between the double-pancake coils as much as possible when developing a superconducting magnet. There is a need for a new winding machine to wind a jointless multipancake coil in a new winding method, thereby avoiding the use of a joint.
