摘要:
基于现场实测，揭示了车辆基地杂散电流的分布规律，以及在钢轨绝缘接头处单向导通装置应用中的不足。阐述了智能导通装置的工作原理，并通过实测数据验证智能导通装置能有效地阻断杂散电流由正线到车辆基地再到正线的电流通路，抑制杂散电流流入车辆基地，进而减少杂散电流对车辆基地内钢筋结构及埋地管线的腐蚀。
Abstracts:
Based on field test, the distribution pattern of vehicle depot stray current and the deficiency of unilateral conduction device in application at rail insulated joint are revealed. The working principle of smart conduction device is expounded. The measured data verifies that the smart conduction device can effectively block the current path of stray current from main line to vehicle depot and then back to the main line, preventing the stray current from flowing into vehicle depot, therefore the corrosion of stray current to the structural reinforcement and buried pipeline in depot is reduced.
