| 中文摘要: |
| 为深入研究超特高压输电电磁辐射环境,分别对500kV变电站和500kV交流输电线路的超高频电磁环境进行了测试与分析。实际测试结果表明,变电站周围产生的超高频辐射场上限频率可达1GHz,线路周围产生的超高频辐射场上限频率可达700MHz,分裂导线将会影响线路的高频辐射场分布。在传播过程中,辐射场电场以垂直极化分量为主,辐射信号峰值随距离的衰减曲线呈非线性关系,远距离处辐射信号以低频分量为主。本次测试得到的规律对研究高压输电的高频电磁环境具有参考意义。 |
| 英文摘要: |
| The ultra high frequency(UHF) electromagnetic radiation environment of both a 500kV AC substation and two 500kV AC transmission lines was tested and analyzed in order to research the electromagnetic radiation environment by UHV power transmission. The result shows that the upper frequency of the UHF radiation field around the substation is 1GHz, and that of the transmission lines is 700MHz. The distribution of the UHF radiation filed is different of bundle conductors. When transmitting in the atmosphere, the mainly components of the radiation electric field is vertical polarization, and the peak values of the radiation signals decay rapidly with the distance increasing with a nonlinear relationship between them. As the distance increasing, the lower frequency components of the field signal are dominant. The test results have significance for study the UHF electromagnetic environment of the high-voltage transmission. |
