摘　　要：目前牵引变电所接地网缺乏有效的腐蚀在线监测手段,无法获得接地网接地极的腐蚀速率,而电化学检测技术是研究接地网接地极材料腐蚀机理的有效手段。本文提出了一种适用于牵引变电所接地网的电化学腐蚀在线监测与评估系统,介绍了其在牵引变电所的应用情况。该系统能够实现接地网腐蚀变化趋势的长期在线监测,有助于从电化学的角度评估接地网的运行状态。The earthing network of traction substation lacks an effective online corrosion monitoring currently,and it is impossible to obtain the corrosion rate of the earthing electrode.The paper presents an online monitoring and evaluation system for electrochemical corrosion of earthing network in traction substation,and introduces its application in traction substation.The system can realize the long-term online monitoring of the corrosion trend of the earthing network,and is helpful to evaluate the operation state of the earthing network from the perspective of electrochemistry.
