一种地下电力电缆对地铁信号电缆影响的评估方法
摘要：
本发明公开了一种地下电力电缆对地铁信号电缆影响的评估方法。其过程为：获取地下电力电缆和地铁信号电缆的施工参数，不断改变施工参数，计算不同参数条件下地下电力电缆发生单相短路故障时对地铁信号电缆的影响值，得到地下电力电缆发生单相短路故障时对地铁信号电缆的影响值曲线，根据影响值曲线对地铁信号电缆受到地下电力电缆的影响进行评估，当影响值超过规定值时，采取对应保护措施。本发明定量计算地下电力电缆对典型地铁用信号电缆的影响，对对地下电力电缆对地铁通信的影响进行评估，合理调整地下电力电缆和地铁隧道信号电缆的施工设计方案，提高地下电力电缆隧道、地铁线路运行的可靠性。
摘要（英）：

The invention discloses an assessment method for influence of an underground power cable on a subway signal cable. The assessment method comprises the steps of: acquiring construction parameters of the underground power cable and the subway signal cable, changing the construction parameters constantly, calculating values of influence on the subway signal cable when a single phase short-circuit fault occurs in the underground power cable under different parameter conditions, acquiring a curve of values of influence on the subway signal cable when the single phase short-circuit fault occurs in the underground power cable, assessing the influence of the underground power cable on the subway signal cable according to the curve of values of influence, and taking corresponding protective measures when the values of influence exceed a specified value. The assessment method can perform quantitative calculation on influence of the underground power cable on the typical subway signal cable, assesses influence of the underground power cable on subway communication, reasonably adjusts construction design schemes of the underground power cable and the subway tunnel signal cable, and improves operation reliability of the underground power cable tunnels and subway lines.
