Research Abstract

A new technique for high-current interruption has been fundamentally studied using polymer nano- and micro-particles dispersed medium. The arc plasma in a circuit breaker contacts the polymer materials which is installed for insulation, which results in polymer ablation. In addition to this, polyamide materials eject spallation microsized particles, which can penetrate the arc deeply. The present work investigated conditions of spallation occurrence.
