The design, fabrication and testing of a closing switch for compact electrical discharge industrial equipment

In this paper investigation results that have been carried out to explain the influence of the compact closing switch parameters on the electric field strength distribution and the breakdown probability taking into account the electrode surface roughness and nonuniform electric field are presented. The dependencies of the breakdown probability as functions of the gap voltage have been determined at various electrode shapes, characteristics of surface roughness and different values of the compact switch inner diameter. The results obtained allow improvement upon the compact closing switch by choosing the appropriate correlation of its parameters.
