Gaoya dianqi, 1986 根据热力学理沦并考虑到电弧的作用,运用数值运算方法对灭弧室气流的解析方程进行了计算。结果显示,气流的改变主要受电弧瞬时功率控制,最大流量不是发生于压力峰值时刻而是出现在电流过零时。在分析电弧对气流影响时,必须同时考虑到弧柱对喉道的障碍作用和电弧对气流的加热效应。

Dianci bileiqi, 2016 高海拔低气压地区的环境受污情况十分严重,而空气间隙电弧和沿面电弧在低气压下的差异报道较少。以玻璃三角板和针板间隙为模型,研究了电弧在两种情况下的直流放电过程,发现染污沿面直流电弧颜色为红黄色,且电弧存在飘弧现象;空气间隙电弧颜色为绿白色,发出很强绿光,且电弧会发生"游走"现象,电弧的颜色将变为红白色,然后变为紫白色,最后回到针板之间,电弧颜色变回绿白色。研究同时发现,随着气压的降低,染污沿面直流电弧与空气间隙直流电弧E-I特性曲线都会向下移动,但两者仍然存在差异:在同等条件下,染污沿面直流电弧的E ...
