讨论了地铁杂散电流防护系统实际运行中出现的问题及其解决的办法,分析了故障产生的原因。其中大部分故障是因为施工不当和电缆被盗引起的。地铁新线建设工程应重视杂散电流防护系统的施工,确保施工按设计要求,不忽视任何细节;运行人员要加强维护和巡视,加强排流柜表计的观察,防止防护系统电缆被盗;发现问题应及时整改,最大限度地减小泄漏电流。
The problems occurred in the actual operation of subway stray current protection system and their solutions are discussed, and the causes of the faults are analyzed. Most of the failures were due to improper construction and cable theft. The construction of new subway line should pay attention to the construction of stray current protection system to ensure that the construction according to the design requirements, without neglecting any details; operation personnel to strengthen the maintenance and inspection, to enhance the observation of drain cabinet meter to prevent the protection system cable theft; Found problems should be rectified in time to minimize leakage current.
