介绍了杂散电流形成的原因,并结合北京轨道交通亦庄线的实际情况,设计了分布式杂散电流监测系统,该系统由参比电极、道床收集网测试端子、传感器、通信电缆、监测装置和排流柜组成。在每一个供电分区内设置一个子系统(包括传感器、监测装置和排流柜),将监测数据上传到SCADA系统,实现了全线的杂散电流监测数据的保存、检索、报表、曲线、分析、预测等功能。
This paper introduces the reason of formation of stray current, and designs a distributed stray current monitoring system based on the actual situation of Yizhuang line in Beijing rail transit. This system consists of reference electrode, test bed of collecting network test terminal, sensor, communication cable, monitoring device And drainage cabinet composition. A sub-system (including sensors, monitoring devices and drain cabinets) is installed in each power supply section to upload the monitoring data to the SCADA system, so as to save, search, report, curve, analyze, Forecast and other functions.
