| Abstract: | Based on the idea that the gas flow for arc-quenching in arc extinguishing chamber is a nonboundary-layer-type flow,a new 2-dimensional mathematical model of nozzle arc is presented in this paper and is used to analyze the arc-quenching properties of SF_6/N_2 gas mixtures. The results of the numerical analysis and the experiment coincide with each other. |
