聚龙一号装置是我国自主研制的首台多路并联超高功率脉冲装置,可根据物理实验的需要工作在不同的脉冲输出模式,负载上获得的电流脉冲前沿75~600 ns、峰值5~10 MA可调。4层圆盘锥型磁绝缘传输线是聚龙一号装置实现超高功率脉冲向负载传输的关键部件,磁绝缘传输线中产生的电流损失会对负载电流波形产生影响并使能量传输效率降低。为此,针对聚龙一号装置,通过全电路计算,在长短两种脉冲输出模式下,研究了磁绝缘传输线的电流损失特性。研究表明:对于电流前沿较快的Z-pinch实验类型,磁绝缘形成过程中外磁绝缘线的损失电流总和约为940 k A,磁绝缘形成后在柱孔汇流区的损失为330~743 k A;而对于前沿较慢的准等熵压缩实验类型,对应的损失分别为223 k A和77~174 k A。
Parc Royale unit is the first multi-path parallel ultra-high power pulse device independently developed in China. It can work in different pulse output modes according to the needs of physical experiments. The current pulse front obtained from load is 75 to 600 ns and the peak value is 5 ~ 10 MA adjustable. The 4-layer disc conical magnetic insulated transmission line is a key component of the PUL-ONE device for transmitting ultra-high power pulses to the load. The current loss in the magnetically insulated transmission line affects the load current waveform and reduces the energy transmission efficiency. For this reason, the current loss characteristics of magnetically insulated transmission line are studied for the Julong-1 device through full-circuit calculation in two kinds of pulse output modes of length and length. The results show that for the Z-pinch experimental type with a fast current front, the total loss current of the outer magnetically insulated wire during magnetic insulation is about 940 kA, and the magnetic loss at the busbar confluence after the magnetic insulation is 330-743 kA While for the quasi-isentropic compression experiment type with a slow frontier, the corresponding losses are 223 kA and 77-174 kA, respectively.
