摘要
主要研究了在100kA微秒级电流脉冲作用下气体火花开关电极物质喷射现象的成因及规律。共进行了4种电极材料的喷射特性实验,实验结果表明,在开关放电过程中,电极表面物质喷射速度方向与材料无关,基本与放电点表面垂直,存在明显的发散角(约为12°)。喷射产物的质量分布近似呈cosnφ分布(n约为1400)。
The experiment of mass jet distribution in gas spark gaps was carried out under microsecond hundred-kiloampere current pulse. Four kinds of electrode materials were studied in experiment. The results show that the direction of mass jet is independent of electrode material and normal to the electrode surface at the arc spot. The angle of divergence is about 12°and the mass distribution of jet is approximate to cos^nφ(n≈1 400).
