Study of post-arc residual plasma dissipation process of vacuum circuit breakers based on a 2D particle-in-cell model

         

摘要

In order to get an insight into residual plasma radial motion during the post-arc stage,a twodimensional(2D)cylindrical particle-in-cell(PIC)model is developed.Firstly,influences of a virtual boundary condition on the residual plasma motion are studied.For purpose of validating this 2D cylindrical particle-in-cell model,a comparison between one-dimensional particle-in-cell model is also presented in this paper.Then a study about the influences of the rising rate of transient recovery voltage on the residual plasma radial motion is presented on the basis of the 2D PIC model.
