项目摘要

As for the stored energy density, the solenoid coil has the larger value. On the other hand, the toroidal field coil has the least leakage flux. The primary concern of HTS SMES coil is the reduction of the cost, while securing superconducting coil performance.For this purpose, the required HTS tape length needs to be as short as possible. The critical current and n values of HTS tapes depends on the magnetic fields as well as its field angle to the tapes. Therefore, the performance of magnets wound with HTS tapes needs to be analyzed based on above factors. The current-voltage characteristics of the HTS coil were analyzed by means of fitting equations of the critical current and n value obtained from the measured values of the Bi2223/Ag tape. The stored energy of four kinds of coil arrangement was analyzed, thereby pursuing the shortest length of HTS tapes.The toroidal field coil comprised of 12 element coils requires 58% longer HTS tapes than the solenoidal coil to store the energy of 100 kJ, but 0.01 T leakage field region at the mid-plane is about a half of the solenoid coil. These properties of two-pole coil and quadrupole coil are situated between them.

就储能密度而言，螺线管线圈具有较大的值。另一方面，环向场线圈具有最小的漏磁通。高温超导磁储能线圈的首要问题是在保证超导线圈性能的同时降低成本，为此，所需的高温超导带材长度需要尽可能短。高温超导带材的临界电流和n值与磁场及其与带材的夹角有关。因此，高温超导带材绕制磁体的性能需要根据上述因素进行分析。通过对Bi 2223/Ag超导带材的临界电流和n值的拟合，分析了超导线圈的电流-电压特性。分析了4种线圈布置方式的储能情况，从而寻求最短的超导带材长度，其中12个单元线圈组成的环向场线圈要存储100 kJ的能量，需要比螺线管线圈长58%的超导带材长度，但中面0.01 T漏场区域约为螺线管线圈的一半。二极线圈和四极线圈的这些特性介于两者之间。
