车辆段内建筑较多，并设有综合维修基地，设备和管线较多，运营环境特殊，因此，与正线相比车辆段是杂散电流防护的薄弱环节。本文以西安地铁三号线港务区车辆段、广州地铁八号线白云湖车辆段为例，提出对一般车辆段及有上盖物业车辆段的杂散电流防护方案。一般车辆段的杂散电流防护由于结构简单、关系单一，只需做好绝缘及回流通道；上盖物业车辆段，由于上盖主体结构在轨道之间，为保护上盖物业及建筑物的安全，应在做好绝缘及回流通道的基础上，增加监测及排流措施。
車輛段內建築較多，併設有綜閤維脩基地，設備和管線較多，運營環境特殊，因此，與正線相比車輛段是雜散電流防護的薄弱環節。本文以西安地鐵三號線港務區車輛段、廣州地鐵八號線白雲湖車輛段為例，提齣對一般車輛段及有上蓋物業車輛段的雜散電流防護方案。一般車輛段的雜散電流防護由于結構簡單、關繫單一，隻需做好絕緣及迴流通道；上蓋物業車輛段，由于上蓋主體結構在軌道之間，為保護上蓋物業及建築物的安全，應在做好絕緣及迴流通道的基礎上，增加鑑測及排流措施。

Since inside the rolling stock depot provided are more buildings,comprehensive maintenance base, more facilities and pipelines,rendering special operation environment;thus,the depot is a weak link in stray current protection compared with the mainline. This article takes the port area rolling stock depot of Xi’an Metro Line 3 and Baiyunhu Rolling Stock Depot of Guangzhou Metro Line 8 as examples for proposing stray current protection solutions for general rolling stock depots and those with superstructures. For the simple structure and single relation,the stray current protection for general rolling stock depots just needs doing well in insulation and the return current circuit.For rolling stock depots with superstructures,as the main structures of the superstructure are distributed in the track space,it requires,in addition to doing well in insulation and the return current circuit, increasing monitoring and current drainage measures,so as to protect the safety of the superstructures and the buildings.
