摘要
直流牵引供电系统中，杂散电流对埋地金属物的电化学腐蚀问题日益突出．对杂散电流的分布、腐蚀、特性以及防护进行理论与仿真分析，可以找出杂散电流防护的一般性原则和方法，为杂散电流的防护提供科学合理的依据，确保轨道交通能够长期安全可靠地运行．
In DC traction power supply system, stray current electrochemical corrosion to the buried metal has be- come increasingly prominent. This article gives the theoretical and simulation analysis on the distribution, corrosion characteristics and the protection of stray current. It can help to find out the general principles and methods of the stray current protection, to provide scientific and reasonable basis for the protection of stray current, ensure that rail transit can run safely and reliably for a long time.
