金属丝在高压电场中通过丝端部与电极极板间的气体放电,完成金属丝的焦耳加热爆炸,充电电容的初始充电电压对金属丝能量沉积产生直接影响.本文使用极板式电爆装置进行实验,建立含气隙的丝电爆电路模型,分析了金属丝段电爆过程中初始电压与金属丝的沉积能量间的关系.研究结果表明:过高的初始充电电压,会使金属丝表面发生击穿放电.当初始充电电压高于特定值时,随着初始电压的增大,金属丝两端电压、通过的电流均出现下降,沉积能量下降.

@@@@When segmented wire falls into the high voltage field,the electrical explosion occurs through the gas discharge be-tween the wire’s ends and the electrodes.It is very important impact of the initial voltage for the deposition energy. In order to ana-lyze the effect of the initial voltage for the deposition energy in the process of electric exploding wires, and the pole-board exploding experiment and theoretical model were established . The result shows that the surface discharge of wire will be occurred when the initial charging voltage is too high,and the amplitude of electric parameter began to decline along with the increase of the applied voltage when the applied voltage surpass a certain value, the energy which deposited on the metal wire began to decrease and its uti-lization began to decline.
