大型桥梁的照明供配电设计分析

Analysis of Lighting Power Supply and Distribution Design of Large Bridge

本文对桥梁照明供配电设计进行了研究,分析了大型桥梁照明供配电方案,明确总体设计方向及思路。阐述了大型桥梁照明供配电系统设计环节,包括变电站选址、配电线路设计、接地系统设计、无功补偿设计、接地故障保护设计等。通过供配电设计,能够提高桥梁照明系统稳定性,切实满足大型桥梁工程日益提高的照明供电需求,保障供配电系统安全平稳运行,也为同类项目供配电设计活动提供参考。

This paper studies the design of power supply and distribution of bridge lighting,analyzes the power supply and distribution scheme of large bridge lighting,and clarifies the overall design direction and ideas.The design links of large bridge lighting power supply and distribution system,including substation site selection,distribution line design,grounding system design,reactive power compensation design and grounding fault protection design,are expounded.Through the power supply and distribution design,the stability of the bridge lighting system can be improved,effectively meet the increasing lighting power supply demand of large-scale bridge projects,ensure the safe and stable operation of the power supply and distribution system,and also provide reference for the power supply and distribution design activities of similar projects.
