ActiveRailway applications—Fixed installations—Electrical safety，earthing and the return circuit—Part 2：Provisions against the effects of stray currents caused by d.c. traction systems
轨道交通 地面装置 电气安全、接地和回流 第2部分:直流牵引供电系统杂散电流的防护措施
Application Summary AI generated
This standard specifies protective measures against stray currents generated by DC traction systems in railway fixed installations. It is applied in the design, construction, and maintenance of rail transit infrastructure, including subways, light rail, and electrified railways, to prevent electrochemical corrosion of metallic structures such as tunnels, pipelines, and reinforcing steel. The standard ensures electrical safety and system integrity by defining requirements for earthing, return circuits, and monitoring of stray current levels.
