摘要：
建立了交流输电线路与输送油气管道平行接近时，前者对后者的电磁影响的模型并进行了计算分析，得到了在交流线路正常运行状态下，相邻长距离输送油气管道对地电压及泄漏电流的沿线分布规律。通过与有限长管道进行分析比较，论述了交流线路对有限长管道及无限长管道的电磁影响的区别，提出了采用无限长管道分析交流线路对长距离输送油气管道的电磁影响较为合理。 |

Abstract:
By means of calculation and analysis of a model that is established for long distance gas/oil transmitting pipeline parallelly adjacent to AC power transmission line, the distribution law of induced potential to ground and leakage current along the pipeline under normal operation of AC transmission line is obtained. Through the comparison to the pipeline with finite length, the difference between the electromagnetic influence on pipeline with infinite length caused by AC transmission line and that on pipeline with finite length is discoursed upon. The authors propose that it is more reasonable to analyze the electromagnetic influence of AC transmission line on long distance gas/oil transmitting pipeline by use of the pipeline with infinite length. |
