缩短两级爆磁压缩发生器输出脉冲宽度的一种有效办法是增大第二级螺旋线圈的锥角,但增大锥角会降低发生器电感压缩比,合理的锥角设计是此类发生器的关键。介绍了三种能带大电感负载、结构紧凑的两级爆磁压缩发生器,第一级结构参数相同,第二级螺旋线圈锥角分别为6°,8°,10°。在电感负载上进行的实验结果表明:其输出电流分别达到140,90和50kA,电流脉冲宽度分别为12.5,8.5和6.3μs,对应的名义输出功率分别为7,7和3 GW。 An effective way to shorten the output pulse width of a two-stage explosion magnet compression generator is to increase the cone angle of the second-stage helical coil, but increasing the cone angle reduces the inductor inductance ratio of the generator, and a reasonable cone angle design is such The key to the device. Three kinds of compact two-stage explosion magnetic compression compressors with large inductive load are introduced. The first-stage structural parameters are the same. The cone angles of the second-stage spiral coils are respectively 6 °, 8 ° and 10 °. Experimental results on inductive loads show that the output currents reach 140, 90 and 50 kA respectively, and the current pulse widths are 12.5, 8.5 and 6.3 μs, respectively, corresponding to the nominal output powers of 7, 7 and 3 GW, respectively.
