| 摘 要： | 铜丝在电爆炸过程中要经历固态、液态、气态和等离子体4种状态,而铜丝在电爆炸过程中吸收的能量全部来自于电流的焦耳热效应,爆炸时周围介质对爆炸过程有着显著的影响.为此对μs脉冲电压下空气和水介质中铜丝电爆炸进行了实验研究,利用自积分Rogowski线圈和电阻分压器分别测量铜丝电爆炸时的电流和电压.利用数学方法分别计算了铜丝...

| Abstract: | Electrical explosions of copper wires in air and water driven by pulsed voltage of a few microseconds were investigated.A self-integrated Rogowski coil and a voltage divider were used for measurements of the current and voltage at the wire load,respectively.The deposited energy during melting,liquid state and vaporization was calculated by a mathematical method.The effects of air and water on deposited energy during three processes mentioned above were analyzed by experiments and calculation.Results show th... |
