盐泰锡常宜公铁两用大桥供配电设计

因大型桥梁具有长距离、分散性、大范围和小容量负荷的供电特点,为提高公铁两用大桥的供配电设计质量,该文结合盐泰锡常宜公铁两用大桥,系统地讨论公铁两用大桥的供配电设计内容。首先,介绍项目概况;其次,分别详细阐述铁路层和公路层供电及照明系统、桥梁夜景照明和桥梁的综合接地系统;最后,对大桥建设范围内受影响的涉电设施迁改进行论述。通过对盐泰锡常宜公铁两用大桥供配电设计全面阐述,为大桥供配电设计师提供参考。

Due to the power supply characteristics of large bridges with long distance,dispersion,large range,and small capacity load,in order to improve the power supply and distribution design quality of the highway and railway dual-purpose bridge,this paper systematically discusses the electrical design content of the combined highway and railway bridge in combination with the Yancheng-Taizhou-Wuxi-Changzhou-Yixing combined highway and railway bridge.First,it introduces the project overview;Secondly,the power supply and lighting system of railway and highway floors,bridge night scene lighting and integrated grounding system of bridges are described in detail;Finally,the relocation of the affected electricity-related facilities within the scope of the bridge construction is discussed..This paper comprehensively expounds the power supply and distribution design of Yantai-Xi-Changyi combined highway and railway bridge,providing reference for the power supply and distribution designers of the bridge.
