摘要
为深入探究不同工作条件下金属丝电爆炸产生的光辐射现象,利用高速相机、光电倍增管等仪器设备构建了同步测试系统。基于该系统,对超细钽丝在高压平台驱动下的电爆炸过程进行研究,详细分析了不同输入电压、数量和长度条件下钽丝电爆炸的规律特征。结果显示:将输入电压从15 kV增加至21 kV时,4#测点处钽丝发出的相对光强由0.13 V增加至3.62 V,发光时间历程从4.23 ms延长至8.42 ms,光饱和时间从150μs减少至20.85μs;当钽丝数量从2根增加到12根时,4#测点处的光强从2.14 V降低至1.16 V,光饱和时间与钽丝数量无明显关系;而当钽丝长度从54.5 cm增加到68 cm时,在爆炸过程中产生的光强减小,发光时间历程从307μs增加至921μs,光饱和时间由23.52μs延长至40.16μs。实验结果为深入研究光敏炸药同步起爆技术提供了数据基础,可为进一步探索和应用提供参考。
To investigate the optical radiation characteristics of wire electrical explosion under various working conditions,a synchronous testing system for the electrical explosion process of superfine tantalum wire is established using high-speed camera,photomultiplier tubes,and other instruments.The optical radiation characteristics of tantalum wire electrical explosion driven by a high-voltage platform are studied,and the characteristics of electrical explosion of tantalum wire under different input voltages,quantities,and lengths are analyzed.The results show that when the input voltage is increased from 15 kV to 21 kV,the relative light intensity emitted by the tantalum wire at the 4#measuring point increases from 0.13 V to 3.62 V,the luminescence process extends from 4.23 ms to 8.42 ms,and the light saturation time decreases from 150μs to 20.85μs.When the number of tantalum wires increases from 2 to 12,the light intensity at the 4#measuring point decreases from 2.14 V to 1.16 V,and there is no significant relationship between the light saturation time and the number of tantalum wires.When the length of the tantalum wire increases from 54.5 cm to 68 cm,the light intensity generated during the explosion process decreases,the luminescence process changes from 307μs to 921μs,and the light saturation time extends from 23.52μs to 40μs.The experimental results can provide a solid data foundation for in-depth research on the synchronous initiation technology of photosensitive explosives,laying an important support for further exploration and application in this field.
