| 摘 要： | 介绍了用于Z箍缩驱动器的快脉冲直线型变压器驱动源(LTD)原型模块设计和初步实验结果。该模块采用32个子块并联,每个子块由两台100kV/100nF脉冲电容器和一只200kV多间隙气体开关串联组成。32只开关由4路高压脉冲分别触发。模块直径为2.9m,厚度约27cm。电路模拟结果表明,在±90kV充电电压下,输出电流幅值为1.0MA,电流上升时间(10%~90%)约118.6ns。初步实验结果表明,在约90mΩ近似匹配电阻负载上获得的电流为995kA,上升时间(10%~90%)为120.8ns,脉冲宽度约335.2ns。实验结果与电路模拟结果较为接近。

| Abstract: | The design of the linear transformer driver(LTD) stage prototype for Z-pinch driver is introduced. The stage consists of 32 identical bricks connected in parallel. Each brick contains two 100 kV/100 nF capacitors, a 200 kV multi-gap switch, and the output connector that transfer the energy to the resistive load. 32 switches are triggered by 4 high voltage trigger cables (8 switches for each cable). The outer diameter of the stage is about 2.9 m, at a length of 27 cm according to the design. The simulation results show that the output current can be up to 1.0 MA in 118.6 ns rise time at the charge voltage of 90 kV. As a result, the stage can deliver 995 kA current pulse with the rise time of 120.8 ns and FWHM of 335.2 ns into a 90 m resistive load in the preliminary experiment. |
