摘要:

对750 kV变电站同塔双回进出线段线路周围的电磁环境进行了研究。以典型进出线段同塔双回线路为模型,分析了相导线间距离、分裂导线的根数、分裂间距、分裂导线子导线直径、导线对地高度等因素变化对导线表面电场强度、无线电干扰和可听噪声的影响;提出了改善变电站同塔双回进出线段线路周围电磁环境的措施。

关键词: 同塔双回, 进出线, 电磁环境, 无线电干扰, 可听噪声

Abstract:

In this paper, the electromagnetic environment for the surrounding of the double-circuit line of a 750 kV substation is studied. Based on the double-circuit overhead transmission line model, the influences of the distance of phase conductors, numbers and spacing of the split conductors, the diameter of the sub-conductor, and the conductor to ground height, on the electric intensity of conductor surface, the radio interference(RI), and the audible noise(AN)are analyzed. Measures to improve the electromagnetic environment are proposed as well.

Key words: double-circuit on a tower, outlet and inlet of substation, electromagnetic environment, radio interference, audible noise
