Triggering Sequential Control of Charging and Detonating for Magnetic Flux Compression Generator

为找出爆磁压缩发生器在规定输入种子电流强度下的最佳起爆时间,对使用电容器作为初始能源的爆磁压缩发生器充电与起爆时序控制进行研究.在理论分析的基础上,制作爆磁压缩发生器测试线圈,实验测量了充电电流波形,结果显示:电流超过5kA的脉宽大于170μs.同时,建立爆磁压缩发生器的三维模型,借助仿真软件,对此模型的起爆过程进行数值仿真,得到发生器装药起爆后到短路开关接通所需的时间26μs.最后根据测试线圈充电实验及三维仿真获得的数据,研究确定爆磁压缩发生器的最佳启动时间.

In order to find the best triggering time of charge detonating under specified input seed current,discharging and firing sequential control of MFCG experiment system using capacitors as initial power is researched.Based on designed size,MFCG test coil is made,and discharging current waveforms are measured in these experiments.These waveforms show：the pulse width of current more than 5 kA is greater than 170 μs.On the other hand,3D model of designed MFCG is built and it is calculated by commercial simulation software,and the time （26μs）from firing generator charge to switching on short-circuiting switch is obtained.Finally,according to the data from test coil discharging experiment and 3D simulating calculation,the beat triggering time of HMFCG is studied.
