摘　　要：为分析高压SF_(6)断路器零区电弧等离子体调控数值,以Eindhoven微观电弧模型为研究对象,探讨不同条件下电弧特性参数的变化。分别针对不同温度、压力及粒子碰撞之间的不同对电弧等离子调控数值进行分析,结果显示随着气压的升高热导率的峰值相应地被推迟到温度较高的区域才出现,并且峰值变小。非平衡态时热导率的变化趋势与平衡态相同,且随着θ的增大,热导率降低。In order to analyze the plasma control values of the zero zone arc in high-voltage SF_(6) circuit breakers,this study takes the Eindhoven micro arc model as the research object and explores the changes in arc characteristic parameters under different conditions.In the experiment,the control values of arc plasma will be analyzed for different temperatures,pressures,and particle collisions.The results of the experiment show that as the air pressure increases,the peak of thermal conductivity is correspondingly delayed and only appears in areas with higher temperatures,and the peak value decreases.The trend of thermal conductivity change in non-equilibrium state is the same as that in equilibrium state,and it varies withθAs the temperature increases,the thermal conductivity decreases.
