摘　　要：在考虑了喷口内壁由于电弧辐射而引起的烧蚀的条件下,建立了一组计算SF_6压气式灭弧室与其喷口电弧的相互作用的数理方程,运用它所得到的计算结果,同GE公司的测试结果很吻合。A mathematical equations for the investigation of the interaction between the puffer chamber and the arc burning in a nozzle has been established. The influence of nozzle inner wall ablation has been taken into account.The calculated results using this model agree quite well with measured values of GE Company.
