摘要

设计了一种具有运动触发极的新型三电极纳秒液体开关。开关由位置固定的阳极、阴极和可运动的触发极组成

开关间隙充入无毒、可生物降解、绝缘性能好的精炼菜籽油。开关腔外的触发极控制系统包括电磁铁、无线接收控制电路和遥控器

无线接收控制电路接收遥控器信号控制触发极运动来调节开关相对间隙

实现开关放电。开关设计工作电压为40 kV。实验结果表明:开关工作电压达到设计要求的40 kV

工作稳定可靠

操作安全简便

与高压脉冲源配套使用

可产生前沿小于2.0 ns、半峰宽25 ns、峰值50 kV/m的双指数电磁脉冲。

Abstract

A new three electrode nanosecond liquid switch with triggering electrode is designed.The switch operates with immobility anode

cathode and a removable trigger electrode.The switch gap is filled with innocuous

fully biodegradable

and well insulating refined rap oil.The trigger’s controlling system outside the high voltage switch includes electromagnet

receiving antenna circuitry

and remote control.Receiving antenna circuitry receives signal from remote control to make switch discharge.The switch is designed to operate up to 40 kV.The experimental results indicate that the switch operates with reliable performance;integrated with the EMP generator

the switch can produce double-exponential electromagnetic field with rise time less than 2 ns

half pulse width around 25 ns and amplitude of 50 kV/m.
