【摘要】 本文对大电流区域交流半波中旋转电弧的发展变化过程及零前500微秒内的电弧形态作了较细致的观察,对电弧电压和速度的极性效应进行了分析。文中还对运动电弧在SF₆和空气两种不同介质中的某些运动特性作了对比更多还原

【Abstract】 Careful observation has been made of the evolution of high current rotating arc within half a. c. cycle and the arc pattern within 500 μs before current zero. The polarity effect of arc voltage and velocity are discussed. A comparison of arc beha-viour moving in air and in SF6 is made.更多还原
