馈电试验在地铁杂散电流干扰排流中的应用

Application of Current Requirement Test to Mitigation of DC Transit Stray Current Interference

埋地钢质管道受地铁动态直流杂散电流干扰的缓解是管道界的一个难题。本工作尝试使用强制电流阴极保护的方式,用强化的阴极保护电流缓解地铁动态干扰对管道的腐蚀影响。馈电试验有助于选取合适的强制电流阳极地床位置以及强制电流阴极保护系统的输出,取得最优的排流效果。

Mitigation of DC transit stray current interference is one of the challenges faced by pipeline industry. In this study impressed current cathoclie protection （ICCP） was tried to mitigate the DC interference from DC transit system, using enhanced CP current as a counteract measure to prevent corrosion. Current requirement test is an optimal method to choose the anode site and output parameters for ICCP system to get an optimized mitigation result.
