摘要: 建立了“聚龙一号”驱动器4层绝缘堆和真空区电路模型。在4层绝缘堆入口处，采用预测−校正的计算方法处理4层绝缘堆的输入电流分配问题，避免了复杂的二维电路模拟，既保证了精度，又大大提高了计算效率。将此新模型加入FCM-PTS程序中，与零维负载内爆动力学程序耦合，得到了各层外磁绝缘传输线的电流波形模拟结果，并改善了负载电流峰值的模拟结果与实验结果的一致性。Abstract: The quadruple-level circuit model for stack and vacuum section of Julong-I facility was established. To avoid complicated two-dimensional circuit simulation, the prediction-correction method was used to deal with the distribution of currents at the entrance of the quadruple-level insulation stack. The accuracy and efficiency were both ensured by this method. By applying this model to the FCM-PTS code coupled with the snow-plow model for the Z-pinch load, the current for each level of the outer magnetic insulation transmission line was obtained, while the coincidence of load currents between simulation and experiment was also improved.
