| 摘 要： | 杂散电流对供电系统周边的环境和基础设施的危害很大,多采用"以防为主,以排为辅,防排结合,加强监测"的原则。结合现场施工经验,介绍了杂散电流检测设备的安装和测试方法,包括参比电极、接线盒、电位测量箱等的安装。该施工方法工艺流程合理,安装精度高,可一次安装到位;解决了上海地区隧道内管片上和地下车站连续墙安装参比电极时容易产生流沙和渗水、高架桥安装的参比电极容易少水而干死等难题;施工作业面大,可合理安排人员、工机具的使用,提高工程效率,保证施工安全。

| Abstract: | As 1 500 V (750 V) DC power supply standard is adopted in urban rail transit power supply system,stray current is easily produced,which is very harmful to the surrounding environment and infrastructure around the power supply system.Therefore,the principle of "placing emphasis on prevention,strengthening the regulation" is mostly carried out in construction.According to years' on-site construction experiences,this paper discusses the installation of stray current testing equipment,including reference electr... |
