轨道交通区间动力照明设计的关键指标分析

Analysis of Key Indicators for Power and Lighting Design in Rail Transit Interval Tunnels

轨道交通区间动力照明设计不能简单地通过提高技术标准来满足工程需求,而应在满足各项关键技术指标的前提下,选择合理的配电方案。介绍了电压偏差允许值、热稳定校验、断路器整定及上下级配合、RCD灵敏性、区间照度标准等关键指标的规范要求,分析了相关计算方法。这些可对轨道交通区间动力照明的设计提供参考依据。

The design of power and lighting systems in rail transit interval tunnels cannot simply rely on improving technical standards to meet engineering needs;instead,it should involve selecting reasonable distribution schemes while satisfying key technical indicators.The standard requirements for key indicators are introduced,including allowable voltage deviation,thermal stability verification,circuit breaker setting and coordination between levels,residual current device(RCD) sensitivity,and lighting standards in interval tunnels.The relevant calculation methods are analyzed,providing a reference for the design of power and lighting systems in rail transit interval tunnels.
