| Outline of Final Research Achievements |
We fundamentally investigated a new technique for dc-current interruption assisted by ablation of polymer micro-particles ejected from the polymer bulk wall. The polymer materials are widely used in a circuit breaker for insulation. They often contact the arc plasma during high-current interruption, resulting in polymer ablation. We found that polyamide materials eject spallation microsized particles, which can penetrate the arc deeply. The present work investigated spallation occurrence due to water absorption.
