【摘要】：基于快Marx发生器技术路线,研制了一套具有高功率密度的低阻抗紧凑型重频脉冲驱动源。采用18级Marx发生器电路结构,每级由1只60nF/100kV脉冲电容器、1个气体开关及隔离电感构成,每两级构成一个模块,整体采用SF6气体绝缘,储能密度达到25.7kJ/m3;采取开放式气体开关,其中两级为触发开关,其余为过电压自击穿开关;触发源采用小型化Marx电路及绝缘胶真空灌封设计。实验中脉冲驱动源单次工作时在约18Ω阻抗负载上输出电压达到765kV、脉宽约160ns、前沿约50ns,功率密度达到157GW/m3;受充电电源功率限制,重复频率5Hz充电70kV,连续5脉冲输出功率约17GW,脉冲波形重复性较好。
[Abstract]:Based on the technical route of fast Marx generator, a set of low impedance compact pulse drive source with high power density is developed. The circuit structure of 18 stage Marx generator is adopted. Each stage consists of a 60nF / 100kV pulse capacitor, a gas switch and an isolated inductor. Each stage consists of a module with SF6 gas insulation. The energy storage density reached 25.7kJ / m3; Adopt open gas switch, two of which are trigger switch, others are overvoltage self-breakdown switch; The trigger source is designed by miniaturized Marx circuit and vacuum encapsulation of insulating glue. In the experiment, the output voltage of the pulse drive source on about 18 惟 impedance load is 765 kV and the pulse width is about 160 ns. The front line is about 50ns, the power density is 157GW / m3; Limited by the power of the charging power, the repetition rate is 5 Hz and the output power is about 17 GW. The repetition of the pulse waveform is good.
