浅谈防雷接地对阴极保护的影响

Influences of Grounding for Lightning on Cathode Protection

防雷接地是由金属导体在地下搭接而成的接地网络,而阴极保护是防止建筑物地下金属构件腐蚀的有效措施。因此,阴极保护与防雷接地存在密切的关系。防雷接地设计应考虑对阴极保护对其的影响,该文以石油天然气管道和储罐接地的防雷接地对阴极保护影响为例,进行探讨分析。

Grounding for lightning is an earthing network which is connected by metallic conductors under the ground, while cathode protection is an effective measure to prevent buildingshnderground metal components from erosion. Therefore, there exists a close relationship between cathode protection and grounding for lightnig. The design of grounding for lightning should take the influences of cathode protection on it into account. This thesis takes the influences of grounding for lightning in oil and gas pipelines and tank grounding on cathode protection as an example to conduct a discussion and analysis.
