Application of Integrated Grounding System in Concrete Poles

阐述了对架空配电线路配置混凝土电杆的要求。介绍了部分预应力混凝土电杆接地电阻的计算。对接地一体化系统的设计、运行维护、经济效益、社会效益进行分析,并阐述了关键技术和试验方法。

When overhead distribution lines are configured with concrete poles with lightning protection facilities and on-pole devices,it is essential to apply reliable grounding.At present concrete pole grounding device is usually composed of one grounded tube（or copper-plated grounding rod）,connected with one ground down lead,and linked to the rod cross arm on the ground of the power supply equipment.The new technology discussed in this paper,is to integrate and combine the aforementioned three separate products,and build it into one concrete pole（integrated grounding system）.After more than half year′s operation in the power supply line,the new product is in good condition,and shows its superiority in maintenance,economy,anti-theft,energy conservation and environmental protection,etc.
