接地极附近杆塔接地体电腐蚀研究

Dianci bileiqi, 2019
相对于周围土壤而言,接地极附近的金属接地体能够提供导电性更强的导电通道,因此金属接地体中也会有接地极中的电流流过,处于土壤中的杆塔接地体因电流和运行环境的作用将会有电腐蚀,从而影响附近线路杆塔的接地性能。结合直流接地极工作条件和附近输电线路电气结构,在3种不同土壤模型的基础上建立了接地极对杆塔影响的理论分析模型;并考虑接地极在不同阴阳极模型条件时,对附近单回单基杆塔接地体的电腐蚀特性展开研究;在不同土壤模型条件下对线路总腐蚀量进行分析,最后针对接地极附近杆塔接地体提出了4种典型的防腐措施。

用作中性点接地电阻的陶瓷电阻的发展和应用

Dianci bileiqi, 1988
对于11～154kV中性点非有效接地输电系统限制单相故障接地时的故障电流值及健全相电压升高均采用中性点接地电阻。过去一般采用金属电阻。现发展一种陶瓷电阻。即无中间层的ZnO线性电阻,其电阻率为数百Ω·cm,为金属电阻的103倍以上。

铜\钢接地网相连时的电偶腐蚀特性实验研究

Dianci bileiqi
为研究铜/钢接地网相连时的电偶腐蚀特性，搭建了模拟铜/钢电极电偶腐蚀的实验平台，测试了铜/钢电极在水和土壤环境中的电偶腐蚀特性，结果表明：铜/钢电极间的腐蚀电位差几乎不受介质电阻率、电极间距、阴极材料影响；电偶腐蚀电流随电极间距、介质电阻率的增大而减小，且存在明显的饱和趋势，仅当相连的铜/钢接地网间距较小时，才能通过增大两地网间距减缓钢地网腐蚀；接地网上各接地体的电偶腐蚀速率都会低于单一接地体存在时的腐蚀速率，且铜/钢接地网相连后，靠近铜接地网的钢接地体电偶腐蚀最严重 ...
