| 摘 要： | 线路雷击杆塔会对附近埋地金属油气管道产生电磁影响,而雷击杆塔时大部分高能量的雷电流直接经过故障杆塔接地体入地,对管道的阻性耦合最为严重,为此研究了1000kV特高压同塔双回交流线路,雷击杆塔塔顶时对附近埋地金属管道的电磁耦合。通过建立雷击暂态电磁场简化计算模型,计算分析了雷击杆塔时特高压同塔双回线路与管道间距、交叉角,土壤电阻率/杆塔接地电阻,以及雷电流幅值等因素对管道干扰电压的影响规律。

| Abstract: | The lightning strike to tower could have electromagnetic effects on the adjacent buried metallic pipelines. The resistance coupling in pipelines is the severest because the most high-energy lightning current is directly injected into the earth by ground conductor of fault tower when lightning strike happens. Thus,for 1000 kV UHV AC double-circuit tower,we studied the electromagnetic coupling in the adjacent buried metallic oil or gas pipelines when the top of tower was subject to lightning strike. By the es... |
