| 摘 要： | 依据现行±500 kV直流技术导则中导线对地距离要求,计算分析了其合成场强的大小。通过计算±500 kV同塔双回直流的合成场强,在与±500 kV直流技术导则要求的电磁环境一致的前提下,给出了推荐极性布置及导线下对地距离的推荐值：居民区14.0 m,非居民区11.0 m。

| Abstract: | In this paper,the total electric field is calculated and analyzed according to the line-to-ground distance as stipulated in the current technical guide for the ±500 kV HVDC overhead transmission line.The distance limit of the ±500 kV double circuit transmission line for given conductors and polar arrangements are recommended for different regions,namely 14 meters for the residential area,and 11.0 meters for the nonresidential,and the recommended distances are found to be in conformity with the same electromagnetic environment as described in the HVDC code. |
