摘要/Abstract

摘要： 分析了匝间无绝缘的超导磁体线圈的结构，主要测试了线圈总层数和每层匝数对其等效总电阻的影响以及线圈的励磁退磁性能.实验结果表明:当总层数为奇数和偶数时，等效总电阻的变化趋势完全不同，但量级均为相邻匝间接触电阻的几倍.等效总电阻大小直接影响着线圈的励磁、退磁过程.线圈总电阻越大，则励磁时间越短，但同时感应电压也越大，焦耳热也会增加.所以，对于无绝缘超导磁体线圈的设计，选择合适的线圈等效总电阻及匝间的无绝缘填充材料尤为重要.

Abstract: The structure of superconducting magnet coils without turn-to-turn insulation was analyzed， and the effects of total number of layers and the turns for each layer on the equivalent total resistance and charge-discharge process of the coils were tested. The experimental results show that the variation trend of the equivalent total resistance is completely different when the total layer number is odd or even， but the order of magnitude is several multiples of the contact resistance between adjacent turns. The charge-discharge process of coils is directly affected by the equivalent total resistance. If the total resistance is greater， the excitation time will be shorter， but the induced voltage will be also larger， and the Joule heat will be increased. Therefore， the appropriate choice of equivalent total resistance and no insulation filling material are particularly important for the design of non-insulated superconducting magnet coils.

Key words: non-insulation, superconducting magnet coil, adjacent turn-to-turn contact resistance, equivalent total resistance, charge-discharge
