| 摘 要： | 研制了一种用于磁绝缘传输线（MITL）实验的分压器型大功率水电阻负载，其阻值可在2.0~14.0 变化。利用MATLAB系统辨识工具箱和ANSYS电磁分析模块,分别获取了分压器的系统传递函数和沿面电场分布，给出了其幅频响应特性和沿面闪络可靠性分析,负载设计充分考虑了集肤效应和温升的影响。该负载已用于强光一号1.0 m长MITL特性研究实验，并获得了较好的测量波形，在负载阻值2.1 条件下，负载峰值电压为1.2 MV，峰值电流为494.4 kA，峰值时间约125 ns。将实验测量结果同TLCODE计算结果进行了对比，获得了较为一致的对比结果。

| Abstract: | A resistive-voltage-dividing high-power load used for experiments of magnetically insulated transmission lines (MITLs) has been designed, and the resistance of this load can be changed from 2.0 to 14.0 . By using the system identification tool of MATLAB and the electromagnetism module of ANSYS, the frequency response and the surface electrical security of the load were studied, respectively. Also, the influences of the temperature and skin effect were particularly considered. The resistive load has been used for one-meter long MITL experiments on Qiangguang-Ⅰ accelerator. With the load resistance of 2.1 , the peak load voltage can reach about 1.2 MV, and the peak current can reach about 494.4 kA with a risetime of about 125 ns. The results of the measurement accord closely with those of the TLCODE calculations. |
