| 摘 要： | 输电线路杆塔利用电杆（铁塔）本体材料作为接地引线。铁塔全金属结构，作为接地引线的性能良好，而混凝土电杆是由地线支架穿钉通过内配钢筋至接地螺栓作为接地引线，由于连接的不可靠和不能检查，故混凝土电杆接地引线导通性能较差。我们测量电杆接地电阻时，只把接地极这部分作为测量对象，忽视了对电杆本体这部分接地引线的测量．从而不能准确掌握输电线路电杆接地电阻情况，给防雷治理和杆塔接地装置改造效果带来较大影响。本文选择输电线路电杆中典型的φ300预应力等径电杆（简称电杆）的导通电阻进行测量研究，为输电线路运行技术管理提供支持。为输电线路运行维护标准的完善和电杆设计制造工作提供信息支持。

| Abstract: | The pole's material is used for the conductive resistance of grounding grid in the electric power supply circuits.The pole's material is well for the ground down lead of electric resistance in iron pagodas,but bad in concrete poles.We only test the conductive resistance of grounding grid.We neglect to measure the conductive resistance of the ground down lead.We cann't accurately examine the conductive resistances of the concrete poles and this will brings bad effects for the defending the thunder and the re... |
