摘　　要：介绍了接地网腐蚀检测的重要性、目前的接地网测量系统及其局限性和接地网腐蚀的机理,研究分析了腐蚀电化学检测技术在接地网上应用的可行性。分析表明,采用腐蚀电化学检测技术对地网定期进行原位腐蚀检测,无需开挖或停运地网便能确定地网严重腐蚀的区域段。The importance of corrosion detection for earthed system, the present detection system for earthed system and its limitation, as well as corrosion mechanism of earthed system are introduced in this paper. The feasibility of applying electro-chemical corrosion detection technology into earthed system is studied. The analysis shows that by using such technology in regular detection of original corrosion, severe corrosion section of earthed system can be determined without open or stop earthed system service.
