| 摘 要： | 本文通过实验研究了焊锡浸渍、励磁电流PI控制、励磁速率以及励磁幅值对高温超导无绝缘线圈励磁电压特性的影响。实验结果表明:高温超导无绝缘线圈励磁电压具有时延特性,焊锡浸渍、励磁电流PI控制分别会增大和减小时延特性,而励磁速率和励磁幅值不会影响时延特性;励磁电压幅值随励磁速率增大而增大;焊锡浸渍可降低励磁电压幅值,而励磁电流控制对励磁电压幅值影响不明显。

| Abstract: | In this paper, we studied the influence of solder impregnation, PI control of ramping, ramping rate and ramping amplitude on the characteristics of ramping voltage by experimental research. The results indicate that the ramping voltage shows a time delay characteristic. Solder impregnation and PI control can increase and decrease the time delay, respectively, and the ramping rate and amplitude do not influence the time delay. Moreover, solder impregnation can decrease the voltage amplitude, while PI control has little influence on the voltage amplitude. |
