SF_6自能灭弧中氟材料对电弧能量利用的影响

Influences of Fluoride Materials on Arc Energy Utilization in SF_6 Self-Energy Arc Quenching

从电弧能量利用观点出发,在SF_6自能灭弧装置中分别放置两种氟材料PTFE和F_(46),在电流3kA^8kA范围内进行开断试验,利用热气体温度的测量结果计算了电弧能量利用系数,并讨论了氟材料在临界电流范围内对电弧能量利用的影响。

From the view of arc energy utilization, two kinds of fluoride materials(PTFE, F46) were used in the SF6 self energy chamber,and the ablation tests were carried out in the arc current range 3kA-8kA. Coefficients of arc energy utilization were calculated with experimental data of hot gas temperature, and influences of the fluoride materials on arc energy utilization were discussed in the range of critical current.
