摘要
根据实际中动态地铁杂散电流干扰的特点设计了室内模拟试验装置,研究了外界干扰电压、总试验时间、每周期干扰持续时间、稳定杂散电流密度相同时不同干扰频率对腐蚀速率的影响,得出动态直流杂散电流对管道的腐蚀行为影响规律。
According to the actual characteristics of dynamic IX2 interference, a lab simulation experiment device was designed. The effects of interference voltage, experimental time, interference duration and different frequencies at the same stray current density on the corrosion rate were studied. The influencing law of DC stray current on the corrosion behavior of pipeline steel Q235 was obtained.
