Researches on Electrode Erosion of Gas Spark Switch Under Pulsed Current
摘要
Abstract
Gas spark switch is widely used in the field of pulsed power technology.As one of the key components,gas spark switch dramatically influences the output parameters and operation stabilities of large-scale pulsed power facilities.Electrode erosion is an inevitable problem,which is concerned and studied since the beginning of the application of gas spark switch from the year 1950 to 1960.In view of electrode erosion of gas spark switch,domestic and overseas researchers extensively studied the following aspects:morphology change of electrode surface,characterization parameters of etch pits,analysis of erosion heat sources,remove forces of electrode material,and effect of electrode erosion on performances of gas spark switch,etc.Several characterization parameters for etch pits on the surface of electrode,as well as classical 1D and 2D models for electrode erosion were proposed.Influences of electrode erosion on triggered performance of gas spark switch under repetitive operation were preliminarily studied.The main problems of the previous researches were analyzed.The probable differences of electrode erosion mechanism under repetitive fast front pulse from the previous researches were discussed.The direction and key techniques of further investigations on electrode erosion were pointed out finally.关键词
