| Abstract: | In order to study the electrode erosion mechanisms of gas spark switch in this paper the erosion micro patterns of the spark switch electrode are investigated. The results show that there are three types of erosion pattern: hole, protrusions and cracks. The mechanisms that arc responsible for these erosion patterns are presented. The erosion pattern can be explained by thermo-blast, magnetism hydro-dynamics and thermo-stress. |
