摘要
从空气间隙绝缘特性、大气条件对放电电压的影响等方面论述了特高压输电电压等级的选择问题、以及特高压交直流输电方式的特点。考虑到高海拔、重污秽等特殊问题,1 000kV作为我国特高压交流输电电压等级是比较合理的选择。
Based on insulation characteristics of gas interval and the influence of atmospheric conditions on discharge voltage, the selection of an appropriate voltage level and characteristics of UHVAV and UHVDC power transmission line are stated. Given such problems as high altitude and heavy pollution, 1 000 kV voltage to UHVAV is suitable.
