输电线路杆塔埋地接地体腐蚀断点散流特性研究

Dianci bileiqi
输电线路杆塔金属接地网长期面临着腐蚀问题，影响接地网的使用寿命及线路雷击防护安全。金属接地体腐蚀会导致杆塔接地网产生断点，进而使得整个接地网的接地电阻超过限值。针对杆塔接地网腐蚀断裂条件下的接地散流问题，建立以虚接导体代替断点仿真计算模型，分析土壤电阻率、入地电流频率及断点位置对方框接地网、方框外延无断点及方框外延有断点的散流特性。结果表明：随着土壤电阻率的增加，方框外延有断点的接地电阻上升率呈现出先增加后趋于饱和的趋势；入地电流频率的改变对方框外延有断点的接地电阻影响不大 ...

季节因素对接地网安全性能的影响研究

Dianci bileiqi
接地安全是电力系统安全稳定运行的根本保证之一，而接地电阻、接触电压和跨步电压是衡量接地网性能重要指标。一方面，本文搭建了双层接地网模型，采用四极法测量了不同土壤含水量的电阻率，探究不同降雨类型、不同雨水渗透深度情况下接地电阻、跨步电压和接触电压的变化规律，仿真表明降雨可以降低接地电阻和跨步电压，但在最初会导致接触电压略微增加；另一方面，土壤冻融均是从表层土壤开始，文中通过实验数据拟合出一定含水量条件下冻土温度与土壤电阻率的规律公式，并从冻土电阻率、冻结深度与解冻深度等不同角度 ...
