Abstract
In this paper, dc arc characteristics in different high pressure gas atmospheres were studied, both in pure N2 and in mixed gases of 20%N2 and 80%H2 at 5 atm. The experiments were conducted in a demountable arc-quenching chamber with double contacts and a transparent glass shield in a 270 V dc circuit. With a high-speed camera, the arc motion is analyzed. The results indicate that H2 and N2 mixed gases have better performance for dc arc extinguishing. Images of pure N2 and 20%N2-80%H2 mixed gas dc arc appearances are presented.
