摘要

详细介绍了一种螺旋线型μs量级高压长脉冲形成线的设计方案, 率先将螺旋线的结构形式应用于μs量级高压长脉冲发生器设计。形成线的内导体为螺旋线, 工作介质为去离子水, 形成线的等效电容为41.25 nF, 等效电感为6.06 μH, 特性阻抗为12.1 Ω, 输出脉冲宽度1 μs, 最高充电电压1 MV, 最大储能20.6 kJ, 匹配状态下输出电压约500 kV。设计结果表明:与采用传统的单筒直线结构相比, 在获取同等脉冲宽度的条件下,采用螺旋线结构可使脉冲形成线的长度缩短75%左右。

Abstract

The design proposal of spiral pulse-forming line with high voltage and μs pulse width is presented, and the spiral structure is firstly used for the generator with μs-long pulse width and high output voltage. The inner conductor of the pulse-forming line is a spiral line, and the working material is deionized water. The basic parameters of the structure are equivalent capacitance 41.25 nF, equivalent inductance 1.06 μH, characteristic impedance 12.1 Ω, pulse width 1 μs, the maximum charging voltage 1 MV, the maximum storage energy 20.6 kJ, and matched output voltage 500 kV. The design result indicates that, with the same output pulse width, the spiral pulse-forming line is about 1/4 the length of the traditional single metal line.
