摘要

为深入理解Marx发生器的建立过程,针对典型线路布局建立了基于不同过压耦合方式的发生器内部过电压产生与分配全电路模型.通过理论分析与电路仿真,研究了不同过压耦合方式下发生器内部开关过电压的产生机制与分布变化规律,结果表明:Marx发生器内部开关上的过压源自对已击穿开关上电压的重新分配;针对发生器不同的线路布局,起主要分压作用的参数及其所构成的分压回路也不同,从而形成不同的内部过电压产生方式与分布变化规律.
        In order to further understand the building process of Marx generator,full-circuit models of the formation and distribution of the overvoltage in the Marx with typical layouts,based on different overvoltage coupling models,were established.The formation mechanisms and the distribution ways of the overvoltage on internal switches of Marx with different coupling modes were studied by theoretical analysis and circuit simulation.It is concluded that the overvoltage on these internal switches of the Marx originates from the redistribution of the voltage on the broken-down switches.According to the different circuit layouts of the Marx generator,the parameters which play the main role in the process of voltage distribution and its voltage distribution circuit are also different,thus,forming the different formation modes and change rules of distribution of the overvoltage.
