摘要
以变电站母线与设备连接线为例,建立了变电站母线与设备连接线工频电场强度数学模型,基于模拟电荷-矩量法,对距离地面1.5m高处平面内的工频电场强度进行仿真计算,得出随着导线间距、导线下悬挂点距地面高度、上下端悬挂点水平距离的不同,电场强度都会发生不同的变化的结论,为此,提出了导线安装设计建议,可作为输变电系统线状电极电场分析的参考。
Taking the substation bus-device connecting wire as example, a mathematical model of power frequency field strength thereof is built. Based on the charge simulation/moment method, the power frequency field strength in the plane 1.5m above the ground is simulated and calculated. It is concluded that the field strength will vary with conductor space, the ground clearance of the lower suspensory point of conductor and the horizontal distance between upper and lower suspensory points. Proposals for the installation and design of conductor are offered, thus providing reference for electric field analysis of line electrode in power transmission and transformation system.
