摘要: 采用金属箔电爆炸过程的二维数值计算模型，对含电爆炸金属箔断路开关的电感储能脉冲功率调节系统进行了数值计算。以此为基础，研制出了一种低电感型的电爆炸箔断路开关，并以4μF/75kV脉冲电容器组作为初级能源，13Ω电阻作为负载进行实验研究。研究结果表明：在负载上可获得约250kV，脉宽大于400ns的脉冲电压。Abstract: By using two-dimensional numerical computation model for exploding foil, the computation is carried out for the inductive energy storage pulsed-power conditioning system with an exploding foil opening switch. On the basis of computation, a low inductance exploding foil opening switch is designed and tested. When energized by a capacitor bank (4μF/75kV), an output pulse voltage of 250 kV with over 400ns duration is obtained on a 13Ω load.
