摘要
聚龙一号装置由24路模块并联组成,通过调整24路模块中激光触发气体开关的导通时序可实现负载电流波形的精确调节,以满足磁驱动加载实验所要求的负载电流波形灵活调节的需求。针对聚龙一号装置开展的磁驱动加载实验,建立了能够描述能量从Marx发生器开始至负载整个传输过程的全电路模型,开发了相应的电路计算程序,并基于实验结果对计算程序进行了校验,电路模拟结果与实验结果符合较好。电路模拟程序的计算效率比采用Pspice软件进行全电路计算的效率显著提高,其不仅可应用于在给定激光触发气体开关导通时序的情况下对聚龙一号装置的输出特性进行预测和评估,同时也为负载电流波形调节的方案设计提供了一种有效工具。
The Primary Test Stand(PTS)facility is composed of24modules combined in parallel.The load current waveform of the PTS could be shaped by adjusting the closing time of the 24 laser triggered gas switches in each module to perform the magnetically driven experiments.A full circuit model describing the magnetically driven experiments on the PTS facility is proposed.The circuit model includes each elements of the machine from the Marx generator to the load.The load current given by circuit simulation is compared with the experiment result,and they agree with each other very well.The calculation efficiency of the circuit simulation code is much higher than that of Pspice software.The circuit simulation code is not only applicable to evaluating the PTS performance by assuming the closing time of the 24 laser triggered gas switches,but also an effective designing tool for the magnetically driven experiments.
