为实现低密度粉末炸药的线同步起爆，研制了一种爆炸丝线起爆系统。储能装置采用3个低感电容并联，总容量为12 μF；采用200 kV/100 kA场畸变开关作为放电开关；触发器产生1.5 kV脉冲经过高压脉冲变压器输出幅度大于40 kV的高压脉冲触发开关。在储能电容器充电40 kV下，电爆炸丝负载上获得了73 kA的脉冲电流。采用高速分幅相机观测了爆炸丝爆炸过程图像，结果表明爆炸丝膨胀过程的同步性较好。该线起爆系统已成功应用于爆炸膨胀环实验。

In order to achieve a low-density powder explosives line synchronization initiation, an exploding wire line initiation system was developed. Three low-inductance parallel capacitors were used in the energy storage device with a total capacity of 12 μF. A 1.5 kV pulse was employed to the primary of the trigger pulse transformer. The pulse transformer generated a 40 kV pulse to trigger the high-voltage switch. A 50 kV/100 kA high-voltage field distortion switch was developed. The system achieved a 73 kA pulse into the exploding wire. High-speed framing camera was used to obtain the image of the exploding wire explosion. The experimental results showed that the synchronization during the expanding process of the exploding wire was preferable. The line initiation system was successfully applied to explosion expanding ring experiment.
