Description

一种变结构的堆叠缆线拓扑及其封装方法 技术领域
本发明涉及电缆线技术领域，更具体的说是涉及一种变结构的堆叠缆线拓扑及其封装方法。
背景技术
二代高温超导材料(REBCO涂层导体)超导材料因其无直流电阻损耗和高传导电流密度的特性，成为了电力设备领域的研究热点，相关应用发展迅速，如超导电缆、超导储能、超导变压器、超导限流器、超导电机等，由于其较高的上临界磁场，在强场磁体应用方面具有巨大的优势。但由于存在较高的宽厚比，使得二代高温超导带材具有各向异性的特征，为了获得更高的工程电流密度并且弱化各向异性，研究人员提出了许多不同类型的高温超导缆线的拓扑结构，包括换位编织的Roble缆线、扭绞堆叠缆线(TSTC)、圆铜芯集束缆线(CORC)等。这些缆线有各自的优势，但又有自身的缺点，其中，由于较高的工程电流密度，堆叠缆线在强场磁体应用领域具有极大的潜力。当采用堆叠缆线绕制线圈时，其作用相当于一个由带材绕制的局部无绝缘线圈，电流可以在缆线内部任意共享分流，提高了磁体本身的鲁棒性。目前业界常用的堆叠缆线制备工艺是采用焊锡在215摄氏度下，直接将多根二代高温超导带材压紧封装，当焊锡固化后就完成了堆叠缆线的制备，其中超导带材的数量可根据堆叠缆线的厚度和带材的厚度进行组合。
二代高温超导带材的临界电流受垂直带材的磁场影响较大，磁场越强，临界电流越低。由于强场磁体中磁场在整个空间中分布往往是不均匀的，导致在线圈磁体中超导材料的临界电流也是分布不均匀的，此时实际运行电流主要取决于整个磁体中某个临界电流最低的区域，即所谓短板效应。为了克 服这种短板效应，则需要对现有的缆线结构进一步优化，使得缆线绕制成的线圈在不同磁场的影响下的临界电流也能达到比较均匀的水平。
发明内容

进一步地，多条所述基带之间为平铺结构。
进一步地，该变结构的堆叠缆线拓扑还包括封装层，所述封装层设于所述堆叠缆线的外壁。
经由上述的技术方案可知，与现有技术相比，本发明公开提供了一种变结构的堆叠缆线拓扑，通过多段所述堆叠缆线依次连接形成缆线拓扑结构，其中，每段堆叠缆线中只设有超导带，或超导带和铜带的组合体以形成变结构的缆线拓扑结构，通过各区域封装的超导带数量不同，将这段缆线用于绕制线圈时，就能够使线圈整体的临界电流沿缆线长度方向上近似均匀，该变 结构的堆叠缆线拓扑设计不仅可以提高线圈的磁场参数，还能最大可能地节省超导带材的用量。
有鉴于此，根据本发明第二方面实施例的变结构的堆叠缆线拓扑的封装方法，具体包括以下步骤：

S40，利用焊锡炉对S30中形成的多层基带进行封装，通过放线盘与导轮的配合压在一起，再穿过焊锡池，基带从150℃-200℃的环境温度下融化的焊锡液体中穿过，从焊锡池出来后，基带上携带的焊锡在空气中凝固形成一根完整的缆线。
进一步地，该变结构的堆叠缆线拓扑的封装方法还包括外部封装，在焊锡炉封装形成的缆线外部利用铜或铝进行封装，形成封装层。
该变结构的堆叠缆线拓扑的封装方法使用上述一种变结构的堆叠缆线拓扑，该变结构的堆叠缆线拓扑各部件之间的连接关系和位置关系均在上述已描述，该变结构的堆叠缆线拓扑的封装方法所达到的技术效果在上述变结构的堆叠缆线拓扑已经描述，在此不做赘述。
