摘要:
为彻底消除杂散电流的危害，提出架空接触网加专用回流轨方案。着重阐述了专用回流轨与限界、车辆、供电系统、轨道及站台门等专业的配合性设计。从建设投资和全寿命周期成本进行专用回流轨的经济性分析。经论证，专用回流轨可有效降低杂散电流防护的全寿命周期成本。
Abstracts:
In order to completely eliminate the harm of stray current, the scheme of overhead contact system (OCS) combining special return conductor rail system is proposed. The supporting design of professions including limit, vehicle, return conductor rail, power supply system, track and screening door in the special return conductor rail system is expounded emphatically. The economic analysis of the system from aspects of construction investment and full lifecycle cost is carried out. Conclusion is arrived that special return conductor rail system can effectively lower the full lifecycle cost of stray current protection.
