水电站铜接地网电化学腐蚀防护问题的探讨

铜接地网最大的隐患是对混凝土中的钢筋构架以及地下的电缆及金属管道造成严重的电化学腐蚀。为消除此隐患,本文通过CCS水电站工程中的接地设计方案,提出在混凝土中接地导体采用穿PVC管保护法和油布防腐法的防护措施。

The biggest trouble of copper grounding mat is the reinforcing steel and underground metal pipes will be eroded because of the electrochemical reaction between the steel and the copper. In CCS hydraulic power station, to avoid the trouble, the new measure of the PVC pipe protection and the fiberglass fabric protection was taken firstly for the CCS grounding mat.
