摘要
SCM技术是现今国际先进的检测技术。本文阐述了应用SCM技术对草桥电厂内埋地金属管道受杂散电流的干扰进行了全面的检测情况,并对检测结果进行了分析。结果发现了地下管道存在保护电位不足的安全隐患,同时排除了三层PE涂层起泡系杂电流造成的推断。
The SCM technology is one of the most advanced detection technology. In this paper, we tested the interference situation of stray current Comprehensively on the metal pipes buried under the Caoqiao power plant, and then, test result were analyzed. The result shows that some security risks existed on the buried pipes because of insufficient protecting potential. At the same time, the result excluded the inference that the stray current would be the cause of forming bubbles on the pipes coated 3-layer PE.
