Abstract
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.
