| 摘要: |
| 考虑双回线路结构对导线起晕电场的影响，采用基于Deutsch假设的解析法，计算分析了线路结构参数对地面电场和离子流密度的影响，得到了最优的导线排布方式。仿真结果表明，在相同导线尺寸与同等架设高度下，双回线路电磁环境明显优于单回线路，且通过合理控制线路参数可以使导线表面电场降低到起晕电场以下，空间离子流密度为0。 |

| Abstract: |
| The analytical method based on Deutsch assumption is adopted to calculate and analyze the effect of structural parameters of transmission line on the ground electric field and ion current density，which considers the effect of the double circuit structure of transmission line on the corona-starting electric field. Therefore the optimal conductor arrangement is obtained. Simulation results show that，with the same conductor size and height，the electromagnetic environment of double circuit line is obviously superior to that of single line and，by the reasonable control of circuit parameters，the conductor surface field can be depressed below the corona-starting electric field and ion current density to 0. |
