Air Circuit Breaker

Usage of polymer materials in a quenching chamber is one of the most effective methods of improving performance of an air circuit breaker [1, 2]. During a high current interruption in the air circuit breaker, an arc discharge touches the insulator, and ablation gasses are emitted [3]. It is considered that the quenching performance and an arc characteristic are affected by this ablation gasses. In order to clarify the quenching performance of each polymer material, we are conducting the experiments. With these experiments, the relationships of the ablation gasses among the number of arcing cycles, arcing peak voltage, arcing conductances, and the pressure rise will be discussed with four kinds of polymer materials.

Different Gases

A high voltage gas blast circuit breaker relies on the high speed gas flow in a nozzle to remove the energy due to Ohmic heating at high current and to provide strong arc cooling during the current zero period to interrupt a fault current. The physical mechanisms that are responsible for the hugely different arc cooling capabilities of two gases (SF<sub>6</sub> and air) are studied in the present work and important gas material properties controlling the cooling strength identified.
