  • 对于低气压或真空环境中的电爆炸丝,因丝沿面击穿会过早终止能量沉积过程,使丝中沉积能量(Ed)大大低于金属丝完全汽化时所需能量(Es). 本文提出并联金属丝法延缓沿面击穿时刻以提高电爆炸丝沉积能量. 对电流上升时间为几十纳秒、幅值约为1 kA级作用下的金属丝电爆炸过程进行了数值模拟. 结果表明,在电爆炸丝两端并联一定尺寸的金属丝可降低爆炸丝端电压上升率,从而推迟电压上升过程中沿面击穿时刻,显著提高丝中沉积能量和过热系数.
    The energy deposition process of electrical wire explosion under vacuum or low gas pressure circumstances is usually terminated prematurely, owing to the flashover along the surfaces of wires. Therefore energy deposited into wires can be far less than the amount needed to fully vaporize them. In this paper, a parallel connection method of wire is introduced in order to improve the energy deposition of the concerned wire before flashover takes place. Wire explosion driven by a current with a rise time of tens of ns and an amplitude of about 1 kA is studied numerically, and the simulation results show that by connecting a wire of a certain size in parallel with both ends of the exploding wire, the voltage rising rate is suppressed and the flashover is delayed; therefore the energy deposited into the concerned wire is increased effectively.
