摘要
输送相同功率时,对采用1000kV特高压输电和5回500kV输电所需线路走廊及其电磁环境作了对比分析,分析结果说明:1000kV特高压输电较5回500kV输电所需的线路走廊可节省98～111m;工频电场、工频磁场、无线电干扰和可听噪声的影响范围也大为减小。
Comparison and analysis on transmission corridor for 1000 kV transmission line and those for fivecircuit 500 kV transmission lines as well as the two electromagnetic environment are performed. Analysis results show that under the same transmitted power, the width of transmission corridor for 1000 kV transmission line can be narrowed dwwn in the range from 98m to 110m than total width of corridors for five-circuit 500 kV transmission lines; meanwhile the effected ranges of power frequency electric field and magnetic field, radio interference and audible noise are evidently decreased.
