Numerical Experimental Study on Plasma Control of Zero Zone Arc in High-voltage SF6 Circuit Breakers
In order to analyze the plasma control values of the zero zone arc in high-voltage SF6 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,pres-sures,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 with θ As the temperature increases,the thermal conductivity decreases.
