发电厂接地材料的选择

Selection of grounding material for power plants

我国电厂传统接地材料大多采用镀锌扁钢,而国外主要接地材料广泛采用纯铜及镀铜钢材。从热稳定性、耐腐蚀性、接地效果及技术经济性等方面对镀锌扁钢和镀铜圆钢进行了对比,指出了镀铜圆钢在接地网应用上的优势。

The traditional grounding material of domestic power plants mostly is sherardized flat steel,and the pure copper and copper plating steels are widely used as grounding material abroad.The sherardized flat steel and the copper plating round steel were compared in several aspects,such as the heat stability,the corrosion resistance,the grounding effect and the technology economy.The advantage of the copper plating round steel used in grounding grid was pointed out.
