摘　　要：针对YBCO高温超导带材在制备磁体过程中性能退化的问题,从骨架结构、预应力、绕制工艺等方面介绍了一种双饼线圈的绕制方法.根据该方法成功绕制了两种规格的双饼线圈,并使用四引线法对线圈的性能进行低温测试,测试结果与设计值的对照表明:线圈性能符合预期目标,绕制工艺稳定可靠,对于高温超导磁体的设计和制备具有一定的指导意义.A YBCO double pancake coil winding method aiming at reducing the performance degradation of superconductor is introduced from perspective of bobbin structure design, winding stress and winding process. Two groups of coils of different sizes were wound and tested at 77K in self-field using the four-wire method. The comparison between the measured value and theoretical value shows that the coil performance conforms to the expectation and the method is proved reliable and applicable for HTS coils winding.
