摘要

开关淬火室中的绝缘体引起烧蚀，并在电弧时释放气体。已知这些释放的气体对电弧特性有影响。本文将介绍八种绝缘子与空气的实验。实验采用数字高速摄像机观察圆弧形状的变化。此外，我们还通过测量电弧电压和电流，测量了从淬火峰到电流为零的电弧电导。弧的形状是从两个方向观察的。

Ablation characteristics of the different kinds of polymer insulators

An insulator in a quenching chamber of a switch causes ablation, and releases gases when arcing. These released gases are known to have an influence on the arc characteristics. In this paper, experiments with the eight kinds of insulators and air will be introduced. The experiments were done by observing the arc shapes changes with digital high-speed video cameras. Furthermore, we measured arc conductance from the quenching peak to current zero by measuring arc voltage and current. The shapes of the arc were observed from two directions.
