The conduction delay time is one of the main technical parameters surface flashover triggered vacuum switch (STVS). Detailed research and optimization characteristics are necessary for development high-performance STVS. In this paper, performance STVS with different electrode structures operating investigated in detail. Based on analysis process, factors affecting discussed. experimental platform built by using a detachable chamber, compared under parameters. This analyzes discusses reasons influence time. results show that structure trigger gap parallel to cathode has better than both perpendicular each other. Both reducing embedment depth extending length can optimize However, increasing only reduces at initial stage operation. shorter distance, smaller addition, current voltage diminish
