摘要

实验研究了空间宽度、电流和大气压对几kA以上大电流空气电弧电弧电场的影响。结果表明，在接近0 MPa-g的条件下，电场随着压力的增大而显著增大，在宽度小于10 mm的受限空间内，电场随着电流的增大而增大。将聚合物与玻璃作为限制材料使用时的电场进行比较，发现除了聚合物的烧蚀或散裂效应使电场增加到1.5-2倍以上外，电场还具有由空间宽度引起的电流依赖性。

Characteristics of electrical field of high-current air arc in restricted slit-like space by polymer plates

In restricted slit-like space by two polymer plates, the effects of the space width, current and atmospheric pressure on arc electrical field were investigated experimentally for high-current air arc above several kA. As a result of the evaluations, it was found that the electrical field increases significantly with the pressure rise under condition near 0 MPa-g, and it increases with current in the restricted space at the width less than 10 mm. Comparing the electrical field in using polymer with glass for the restricted material, it revealed that the electrical field has current dependence caused by the space width in addition to increasing effect to above 1.5–2 times by the ablation or spallation effects of the polymer.
