Dianci bileiqi, 2016 以Agrawal耦合模型为基础,利用二维时域有限差分方法,研究了城市建筑物对理想地面架空线附近的雷电电磁环境和架空线上感应出的耦合电压的影响,并分析了建筑物位置、建筑物高度以及回击电流参数等因素对电磁环境及耦合电压的影响差异。结果表明:建筑物的存在削弱了架空线附近的垂直电场,当建筑物分别位于架空线两侧时,水平电场方向相反;建筑物高度的增加对架空线附近的水平电场波形影响不大,当建筑物高度或者建筑物与闪电通道距离增大时,垂直电场均减小;对于15 m高的建筑物,当它与闪电通道分别位于架空线路同侧及异侧时 ...

Dianci bileiqi, 2015 为了能在地面探测空中雷暴云电荷的空间方位,提出了一种利用地面三维大气电场和相对介电常数的测量来确定雷暴云电荷方位的方法。文中分析了空中电荷在地表产生的电场大小和方向关系,建立了雷暴云和大地的静电场分布模型,给出了通过三维大气电场值和地表介电常数值反演空中雷暴云电荷方位的公式。通过自主研发的电场探测系统,发现在干燥土壤,岩石等相对介电常数较小的地表存在较大的水平电场分量,验证了在地面探测雷暴云电荷方位的方法具有可行性。
