项目摘要

It is expected to develop the devices for protection of some production plants, such as semiconductor production plants, from momentary voltage drops. These devices are required to output the power of several MW for 1 second. As one of candidates, superconducting magnetic storage systems (SMES) using conduction cooled superconducting pulse coil wound with low temperature superconducting (LTS) conductors, are expected. The study has been carried out to develop the conduction cooled LTS pulse coil with low cost. In case of using NbTi wires which are produced with the lowest cost, it has been shown that pulse coils can be fabricated with low cost by using the superconducting conductors with high resistive matrix such as CuNi. In case of using Cu stabilized NbTi wires with high stability, it is shown that coil performance can be improved by both of using NbTi tapes and optimizing thermal diffusions from superconducting conductors to coil structures. In addition, improvement of performance of the MgB2 wires which are expected to use at 20K has been studied. It has been cleared that deformation of cross-sectional shape from the round shape into the tape shape is valuable for improvement of the wire performance from experiments using short samples of MgB2 tapes. Moreover, the design method to make the best use of the MgB2 tapes has been studied. The coil which can generate 3T of magnetic field has been wound by the parallel conductor composed of two tapes. It has been shown experimentally that the coil can drive stably.
预计将开发用于保护某些生产植物的设备,例如半导体生产植物,免受瞬时电压下降。这些设备需要输出多个MW的功率1秒。作为候选人之一,预计使用传导冷却的超导脉冲线圈缠绕具有低温超导(LTS)导体的超导磁性存储系统(SME)。已经进行了研究以低成本开发传导冷却的LTS脉冲线圈。如果使用成本最低的NBTI电线,则表明可以通过使用具有高电阻矩阵(例如CUNI)的超导导体来制造脉冲线圈。如果使用具有较高稳定性的Cu稳定的NBTI电线,则表明可以通过使用NBTI磁带并优化从超导导体到线圈结构的热扩散来改善线圈性能。此外,已经研究了预计将在20K时使用的MGB2电线的性能提高。已经清除了,从圆形形状到胶带形状的横截面形状的变形对于使用MGB2磁带的短样品从实验中改善电线性能很有价值。此外,已经研究了充分利用MGB2磁带的设计方法。可以生成3T磁场的线圈已由由两个磁带组成的平行导体缠绕。经过实验表明,线圈可以稳定驱动。
