摘　　要：杂散电流能够对埋地钢制管道造成很大的危害和破坏,严重影响管道的安全运行。应用智能杂散电流检测仪(SCM)对埋地钢制管道上的杂散电流干扰进行测试,通过对检测结果分析发现,智能杂散电流检测仪功能齐全,能够沿管道路线检测管道上各种杂散干扰电流的大小和方向,排除不需要的干扰信号,确定干扰源类型和来源;能够准确判断管道上杂散电流流入点和流出点位置,为进行排流改造提供依据。Stray current can cause great damage to buried steel pipelines,and seriously threatens the safe application.The smart stray current mapper（SCM）is used to detect stray current on buried steel pipeline,with the results showing that the SCM has a variety of functions,so it can detect the magnitude and orientation of all kinds of stray current,eliminate the needless interferential signal,and determine the type and source of stray current.The SCM can estimate the inflow and discharge points exactly and provide a basis for electric drainage.
