摘要
为评价杆塔导电混凝土基础接地的防雷效果和导电混凝土基础的稳定性和安全性,利用国际通用接地分析软件CDEGS仿真分析了接地方案、土壤电阻率、导电混凝土电阻率和接地体长度对雷电冲击下导电混凝土基础冲击接地电阻的影响,研究了雷电冲击下导电混凝土基础的稳定性和安全性,并得出了相关结论。
In order to evaluate the lightning protection effect of the conductive concrete foundation grounding of the tower and the stability and safety of the conductive concrete foundation,the effects of grounding scheme,soil resistivity,conductive concrete resistivity and the length of grounding body on the impact grounding resistance of conductive concrete foundation under lightning impulse are simulated and analyzed by the international grounding analysis software CDEGS.The impact of grounding resistance of conductive concrete foundation under impact,and the stability and safety of conductive concrete foundation under lightning impact are studied.Finally,the relevant conclusions are draw.
