摘　　要：1000kV配电装置导线是保证特高压交流输变电工程电气技术条件的重要组成部分,电晕产生的无线电干扰和可听噪声对环境的影响是特高压导线选型和分裂形式选择的最主要因素之一。文章结合我国1000kV交流特高压试验示范工程的实际情况,对1000kV变电站导线的选型和分裂形式进行优化,确定最优分裂间距及次档距,使导线在满足电气性能和机械性能的前提下,尽可能降低对环境的不良影响。The conductors used in 1000 kV distribution devices are the important component to ensure electrical specifications of ultra high voltage （UHV） AC power transmission and transformation projects. The corona caused influences of radio interference and audible yawp on environment is one of the principal factors in the selection of both conductors for UHVAC devices and split form of conductors. According to practical condition of 1000 kV AC power transmission demonstration project in China, the conductor selection and conductor split form for 1000 kV AC substations are optimized, then the optimal bundle spacing of split conductor and subspan are decided. Thus, under the presupposition of satisfying electrical and mechanical performances, the harmful effect on environment is reduced as far as possible.
