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 ...

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。

面向环保接地施工的杆塔分支式外延接地网接地特性研究

Gaoya dianqi
低碳环保已成为国家的战略和政策导向，输电杆塔在降阻施工时，常采用敷设长距离外延接地极方式接地，造成资源浪费、环境破坏等问题。针对杆塔接地施工环境的复杂性与施工面积的有限性，文中提出输电线路杆塔分支式外延接地网散流降阻结构，实现了接地降阻施工的低碳环保。首先，仿真计算单根外延接地极的有效降阻长度；然后，研究了土壤电阻率、入地电流频率对单分支式和多分支式外延接地网降阻特性的影响规律；最后，分析了不平衡分支式外延接地网的散流特性。结果表明：相比于传统方框带射线型接地网，分支接地极结构比例为1 ...
