大理典型密集输电通道雷击特性分析

open access: yesDianci bileiqi
选取大理地区典型密集输电通道为研究对象,根据线路实际结构及参数,建立了雷击过电压计算模型,通过计算各线路的耐雷水平,获得了密集线路的防雷薄弱段;分析了交叉跨越线路的电磁耦合特性,以及雷击上层线路时对下层交叉跨越线路的影响情况;研究了临近线路之间的雷电屏蔽效应,计算了考虑雷电屏蔽效应后紧凑并行线路的绕击跳闸率。结果表明:由于杆塔接地电阻的影响,各线路的反击耐雷水平差异较大;雷击上层羊丽Ⅰ回线时,不会造成下层交叉跨越线路剑鹤中线闪络跳闸;当剑鹤中线和羊鹤Ⅰ回线线路段的间距为40 m时,考虑雷电屏蔽效应后 ...
