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。

盘形悬式绝缘子电晕的研究绝缘子元件电晕放电会产生噪音。为了提高决定噪音水平的绝缘子容许电压,开展了悬式绝缘子电晕的研究。连续地升高工频电压,就可求出发生可见流光电晕的电压与其结构的关系。还求出了与水泥胶合剂端场强最大部位的圆断面的半径的关系。[摘译自...
