摘要
选取了某条拟建220 k V输电线路为研究对象,对6种不同架设方式下,线路产生的电磁环境影响大小进行了理论预测和分析。结果表明,混压线路随着叠加的电压等级的降低,产生的电场强度逐渐下降,允许最低线高逐渐降低;并行线路电场强度最大值出现在塔基横担外侧。预测结果为电磁辐射环境管理提供了理论依据和技术支撑。
The paper selects the 220 kV transmission line as the research object, and carries on the theoretical forecast and analysis on the influence of the electromagnetic environment of the line under the 6 different kinds of erection methods. The results show that the electric field intensity decreases gradually with the decrease of the voltage level of the mixed voltage line, which allows the lowest line height to be reduced gradually. The electric field intensity maximum of parallel lines appears outside the tower. The forecast results provided theoretical basis and technical SUODort for electromagnetic radiation environment management.
