| 摘要: |
| 针对爆磁压缩发生器高精度延时起爆控制的要求，建立了基于电路控制延时方案的最佳起爆时序模型，分析了其时序误差散布。设计了一种爆轰驱动飞片型高功率放电开关，通过数值仿真分析了开关的耐压能力及飞片变形。实验测试了6发开关的闭合放电性能，数据表明：开关两极间电压5kV时未出现击穿现象，闭合响应时间分布在66±5μs以内、标准差2.7μs，开关导通时间≥900μs，放电效率接近90%。采用小型爆磁压缩发生器与延时控制系统进行了联调实验，结果表明：爆磁压缩发生器运行时刻与电流峰值时刻相差1.8μs，延时误差7.8%，延时控制系统满足高精度起爆控制的要求。 |

| Abstract: |
| Time-delay control system is very important to magnetic flux compression generator’s operation. Based on circuit delay scheme, an appropriate model was built to analyze the initiation time sequence, and its errors dispersion was analyzed. A switch driven by detonation was proposed, its voltage endurance capability and plate deformation were analyzed by simulation. On this basis, six switches were tested at high voltage. The data shows that, there is no voltage breakdown at 5kV, response time distributes in 66±5μs with standard deviation of 2.7μs, conducting time is equal or greater than 900μs, discharge efficient is approximately equal to 90%. A mini type magnetic flux compression generator was used to test the time-delay control system and the results show that, the time difference between magnetic flux compression generator’s operation and current peak is only 1.8μs with the error being 7.8%. |
