摘　　要：整理和分析了中国电力科学研究院和云南电力试验研究所有关换流站直流场典型电极的操作波放电特性模拟试验数据,讨论了不同海拔高度下典型间隙的操作冲击放电电压的校正方法。文章指出:可以根据IEC和国家标准提出的g参数法以及文中得出的典型间隙公式确定海拔2000m以下的换流站直流场的空气间隙。The paper analyzed the simulation testing data owned by China Electric Power Research Instutyte and Yunnan Ekectruc Power Testing and Research Institute about switching surge discharge characteristics of the typical electrode for DC field in converter station, and discussed the correction methods of switching surge discharge characteristics for typical aur gap in different altitude above sea level The conclusion in the paper is that the air gap for DC field in converter station under 2000 m altitude above sea level can be determined according to the g parameter method presented by IEC and national standard as well as the typical gap formula got in this paper.
