摘要
本文介绍了用金属管道的传输线型等值模型分析埋设于均匀土壤中的HVDC圆环接地极的大地回流对地下金属管道、电缆等的影响。着重探讨了接地极的埋深、到接地极的距离等因素对地下金属管道所受腐蚀的影响,并得出若干相应的结论。
Using the transmission line equivalent model of metallic pipelines.the effects of the earth-returned current
from an HVDC toroidal grounding electrode buried in the homogencous soil on underground metallic pipelines and cables
were analysed in this paper. The influence of some geometrical factors.such as electrode depth,distance to the electrode.
etc. on corrosion of the pipelines were emphatyically investigated and the relevant conclusions obtained.
