介绍了预脉冲抑制电感值的选取、大体积电感值的计算、电感在传输线内筒中的绝缘设计和主脉冲在电感上的传输时间以及等效阻抗。根据对电感值与传输线、输出线电压和二极管电流之间关系的数值模拟,预脉冲抑制电感应取值5μH,并通过实验给出了屏蔽筒中大型电感的计算方法。根据对电感管与传输线内筒之间以及电感匝间电场强度的分析和数值模拟,确定了电感长度630 mm、外径1 160 mm和管径102mm。通过对电感与传输线内筒之间构成的带绕螺旋传输线等效PSpcie的模拟计算,得到了电感传输线支路上的单次传输时间为349 ns,大于主脉冲的宽度;在主脉冲期间,带绕传输线的阻抗大于25Ω,也远大于传输线的阻抗。通过内置式预脉冲抑制电感已向水介质同轴线中的气体开关引入了触发高压和工作气体。
The selection of pre-pulse suppression inductance, the calculation of large-volume inductance, the insulation design of the inductor in the inner tube of the transmission line and the transfer time of the main pulse on the inductor and the equivalent impedance are introduced. According to the numerical simulation of the relationship between the inductance and the transmission line, the output line voltage and the diode current, the value of the pre-pulse suppression inductor should be 5μH, and the calculation method of the large inductor in the shielding tube is given through experiments. According to the analysis and numerical simulation of the electric field strength between the inductor tube and the inner tube of the transmission line and between the turns of the inductor, the length of the inductor is 630 mm, the outer diameter is 1 160 mm and the diameter is 102 mm. Through the simulation of the equivalent PSpcie with helical transmission line formed by the inductance and the inner tube of the transmission line, the single transmission time on the branch line of the inductance transmission line is 349 ns, which is greater than the width of the main pulse. During the main pulse, Transmission line impedance greater than 25Ω, also much larger than the impedance of the transmission line. Inductive high-pressure and working gases have been introduced into the gas switch in the coaxial line of water media by the built-in pre-pulse suppression inductors.
