摘　　要：近年来,我国陆续建设了多个750k V和1000k V特高压输电工程。为适应这种变化,GBJ 143-90《架空电力线路、变电所对电视差转台、转播台无线电干扰防护间距标准》需要进行修订。本文将结合标准修订工作,对750k V和1000k V交流架空电力线路、变电站(所)对电视差转台、转播台无线电干扰防护间距的研究方法及初步结果进行总体性介绍。China has built many 750kV/1000kV UHV transmission projects in recent years.In order to adapt this situation,the standard GBJ 143-90“Protective Spacing of Radio Interference From Overhead Electric Line and Substation to TV Transposing Stations and Retransmitting Stations”needs to be revised.Based on the revision work of standard,this paper generally introduces the method and preliminary result of protective spacing of radio interference to TV transposing stations and retransmitting stations from 750kV/1000kV AC overhead electric lines and substations.
