摘　　要：延时控制系统是保证爆磁压缩发生器运行的关键部件,介绍了传统平板型开关延时控制系统的工作机制,分析了其优缺点。在此基础上,通过理论和实验研究,对平板型开关延时控制系统进行了改进,采用固化的同轴式导爆索接通开关,提出了一种符合爆磁压缩发生器工作要求的同轴型开关延时控制系统,测量了导爆索的爆速和固化开关的导通时间,并在爆磁压缩实验中对该延时控制系统的性能进行了验证。Timing control system is the important element for Magnetic Flux Compression Generator （MFCG） ＇s operation. This paper introduced the operating principle of classical timing control system using flat switch along with an analysis of its merits and drawbacks. Then it improved the classical timing control system by means of theoretic and experimental study, and designed a kind of timing control system, which used primacord and solidified coaxial switch. Furthermore, the explosive velocity of primaeord and opening time of solidified switch were measured. Finally, the system in the experiment of MFCG was verified.
