摘要：
由高温超导涂层导体制成的罗贝尔电缆可以通过紧凑的设计和降低的交流损耗来传输大电流。因此，它们是制造电机和发电机等高温超导应用线圈的良好候选材料。在本文中，我们提出了实验直流和交流特性的几个线圈组装从一个5米长的罗贝尔电缆建在KIT，不同的匝数和匝间距。我们的实验，有限元法（FEM）计算的支持下，表明，一个更紧密的缠绕罗贝尔线圈，尽管有一个较低的临界（因此操作）电流，可以产生一个更高的磁场比一个松散的缠绕。对于线圈中心产生的给定磁场，所有线圈都具有类似的AC损耗，除了最松散缠绕的线圈之外，由于产生所需场所需的相对大的电流，该线圈具有高得多的损耗。在本文中提出的实验进行的几何形状的煎饼线圈的罗贝尔电缆，但他们是一个更一般的策略，耦合实验和数值模拟，可以用来优化线圈设计相对于不同的参数，如磁带数量，大小，或交流损耗，其相对重要性是由特定的应用程序。
英文摘要：
Roebel cables made of HTS coated conductors can carry high currents with a compact design and reduced AC losses. They are therefore good candidates for manufacturing coils for HTS applications such as motors and generators. In this paper we present the experimental DC and AC characterization of several coils assembled from a 5 meter long Roebel cable built at KIT, which differ in the number of turns and turn-to-turn spacing. Our experiments, supported by finite-element method (FEM) calculations, show that a more tightly wound Roebel coil, despite having a lower critical (and therefore operating) current, can produce a higher magnetic field than a loosely wound one. For a given magnetic field produced at the coil's center, all the coils have similar AC losses, with the exception of the most loosely wound one, which has much higher losses due to the relatively large current needed to produce the desired field. The experiments presented in this paper are carried out on the geometry of pancake coils made of Roebel cables, but they are exemplary of a more general strategy that, coupling experiments and numerical simulations, can be used to optimize the coil design with respect to different parameters, such as tape quantity, size, or AC loss, the relative importance of which is dictated by the specific application.
