| 摘 要： | 为了研究金属导体在不同介质中的电爆炸机理及放电规律，进行了不同起爆电压作用下，铜丝在水和空气两种介质中的电爆炸实验.采用罗果夫斯基线圈和高压探头分别测量了铜丝电爆炸过程的爆发电流及电压，获得了铜丝电爆炸的电性能参数.分析了起爆电压及放电介质等因素对铜丝电爆炸性能的影响规律.结果表明，相同起爆电压作用下，铜丝水中电爆炸的爆发时间滞后于空气中的爆发时间，水中电爆炸的能量沉积率高于空气中，且当起爆电压较低时铜丝在水中电爆炸较难发生二次放电.

| Abstract: | In order to study the electrical explosion mechanism and rules of the metal conductor in different media, a series of copper wire electrical explosion experiments have been conducted in water and in air under the different initiation voltages. The burst currents were measured using a Rogowski coil and the burst voltages were measured using a high-voltage probe. And then, the property parameter of electrical explosion of the copper wires are obtained. The influence of initiation voltage and medium on the properties of electrical explosion have been analyzed. The results show that under the same initiation voltage, the burst time of the copper wires in water lags behind the burst time in the air, and the energy deposition rate in water is higher than that in air. When the initiation voltage is low, wires explosion in water is hard to occur for secondary discharge. |
