地铁杂散电流腐蚀防护系统相关问题探讨

摘要

论述地铁牵引供电系统中的杂散电流腐蚀防护系统,讨论地铁杂散电流腐蚀产生的机理及其危害,阐述治理杂散电流所采用的方法和防治原则,简要介绍目前应用的杂散电流监测系统和排流柜之间的关系,对杂散电流腐蚀防护提出合理建议.%This article describes the principles of generation of metro stray current and its corrosion to protective systems, e-laborates the protective measures adopted to prevent the stray current, and briefly introduces the relation between stray current monitoring system and current drainage cabinet used at present, with suggestions to prevent the stray current corrosion given in the end.
