摘　　要：对整只避雷器多波形冲击电流试验设备参数和整只避雷器电气参数进行计算,分析了整只避雷器冲击电流试验设备回路参数的选择对回路设计的影响,提出了一种多功能冲击电流试验设备的设计思路,按此思路研制出了一种整只避雷器试验用多波形冲击电流试验设备,该试验设备可以按标准要求进行35 kV及以下电压等级避雷器的4/10冲击电流耐受试验、8/20冲击电流波形下重复转移电荷试验以及残压试验、(200~230)μs波形下重复转移电荷试验、30/80操作冲击电流残压试验。Through calculating the arrester multi-wave impulse current test equipment parameters and the arrester electrical parameters,the influence of test circuit parameter selection on circuit design of the complete arrester impulse current test equipment is analyzed. The author also presented a methodology to design a multi-waveform impulse current test equipment. An impulse current test equipment is made to conduct the 4/10 impulse current withstand test,8/20 and( 200 ~ 230) μs repeative transfer charge test,30/80 impulse current residual voltage test according to the standard.
