本文研究了在5个大气压下纯N_2和20%N_2与80%H_2混合气体中不同高压气氛下的直流电弧特性。实验是在一个可拆卸的灭弧室中进行的，该灭弧室具有双触点和透明玻璃屏蔽，在270 V直流电路中。利用高速摄像机对电弧运动进行了分析。结果表明，H2和N2混合气体具有较好的直流灭弧性能。给出了纯N_2和20%N_2 - 80%H_2混合气体直流电弧形貌的图像。
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.
