摘要
针对新线建设期建立杂散电流收集网的合理性问题,建立杂散电流防护系统静态模型,对收集网3种不同条件下的钢轨泄露电流和电压进行仿真分析。提出在地铁运营初期杂散电流防护系统排流装置未投入运行的情况下,在建设期建立杂散电流收集网是不合理的,建议选择更加合理的分步预留和建设模式。
Aiming at the feasibility of establishment of the stray current collection network at the new line construction period,a static model of stray current protection system is established,making thesimulation analysis of the collection network under3different conditions of the rail leakage current and voltage.This paper points out that it is not feasible to establish a stray current collection network in the construction period with current drainage device in stray current protection system not yet put into operation at the early metro operation period.It is recommended to select more reasonable step by step reservation and construction mode.
