电弧电压及燃弧时间的分析研究

The Experimental Investigation of Arc Voltage and Arc Duration

本文根据电弧基本理论，对银基触头材料开断电阻性负载的电弧电压及燃弧时间进行了实验研究，通过分析比较得出，开断电流越大．燃弧时间越长，电弧电压的变化遵循交流电弧的伏安特性的结论。

The experiments of arc voltage and arc duration of silver - based contact maten- als under breaking resistance load are made according to the arc theory,by analyzing the experi- mental results, the conclusions, the bigger the breaking currents,the longer The arc duration, the variation of arc voltage accords with the V - 1 charactenstics of AC arc, are obtained in this paper.
