摘　　要：在避雷器参数与选用等相关铺垫的基础上,提出并剖析经实践总结得出的避雷器设计口诀。探讨特/超高压和直流等高大瓷套型避雷器的人工污秽试验、较高电压等级避雷器监测器的压力释放试验和门槛动作电流等焦点问题。提出选用避雷器时应注重性价比。Base on the parameters and selection of surge arrester, design mnemonics of surge arrester are given out and analyzed, which come from specialized practice many years. Focal question of surge arrester, such as artificial pollution test big porcelain type surge arrester for UHV/SHV or DC, pressure relief test of monitors of higher voltage surge arrester, threshold action current are discussed. It is proposed that surge arrester selection should put stress on cost performance.
