| 摘 要： | 为研究雷击杆塔时经接地体泄散的雷电流在杆塔周围地面产生的电位分布及其影响，采用模拟试验的方法，在半球形接地池中对不同幅值冲击电流作用条件下几种典型形状杆塔接地极周围的地面电位分布特性进行了试验研究，测得了相应的等电位分布曲线。将所得电位分布曲线按模拟比进行换算后，估算出接地极附近地面可能作用于人体的暂态跨步电压。通过对... |

| Abstract: | We researched the potential distribution of grounding electrode under impulse current and its influence by simulation.The test area was in a hemispherical grounding pool,the impulse current of different amplitudes was applied to the grounding electrodes of some representative structures,and the potential distribution curves around the grounding electrodes were measured to understand the characteristics of potential distribution.Converting the potential distribution curve by simulation scaling factors,the tr... |
