摘要
研究了X-pinch和回流柱之间的分流关系,以及两个X-pinch之间的分流关系。在X-pinch和回流柱的分流实验中,X-pinch上的电流与回流柱上的电流大体相等,这表明电流分布不只与X-pinch或回流柱的特性有关,而且也与它们所在回路的其他部分有关。在两个X-pinch之间的分流实验中,X-pinch上的电流与X-pinch本身的材料和直径几乎无关,这确认了电流分布与回路中X-pinch之外的部分有关。离绝缘柱远的X-pinch上的电流总是比离绝缘柱近的X-pinch上的电流略大一些,这是并联回路之间的互感造成的。
Abstract
Current distribution between X-pinches and current-return rods was studied, considering the effect of mutual influence between different branches. In the experiment of current distribution between an X-pinch and a copper current-return rod, the current in the X-pinch is roughly the same as that in the current-return rod, which reflects that current division depends not only on the characteristic of the wires/rods, but also on the features of the other parts of the loops. In the experiment of current distribution between two X-pinches, the current flowing through the two X-pinches does not depend on the diameter or material of the X-pinch, confirming that current division has something to do with the parts of the parallel circuits other than X-pinches. The amplitude of current flowing in the X-pinch farther from the polyformaldehyde isolation rod is always slightly higher than the other, indicating the influence of the mutual inductance between the branch circuits.
