摘要:
城市轨道交通杂散电流会对周边的埋地金属管线造成腐蚀和破坏。介绍了轨道交通杂散电流的危害、评判标准及常规的防护措施,从防护间距、加强绝缘、主动防护等方面提出了特殊区段的加强防护措施,并设计了一种新型轨道交通沿线金属管线的杂散电流防护装置。
Abstracts:
The stray current can cause corrosion and damage to buried metal pipelines near track. The hazards of rail transit stray currents, evaluation criteria and regular protective measures are introduced, and enhanced protective measures for special sections in terms of protective spacing, reinforced insulation and proactive protection are proposed. A new type of stray current protection device for metal pipelines along track is designed.
