摘要
在隧道照明领域,传统交流供电面临电压波动、线路损耗高及成本大等挑战。与之对比,直流配电技术凭借稳定性高、线路损耗低、灯具寿命长等优势,逐渐成为弥补传统供电技术不足的优选方案。本文通过对比交流远供与直流远供系统,深入剖析直流配电技术在隧道照明中的优势。并结合隧道工程案例,提出直流集中驱动控制照明供电技术方案。
In the field of tunnel lighting,traditional AC power supply faces challenges such as voltage fluctuations,high line losses,and high costs.In contrast,DC power distribution technology has gradually become the preferred solution to make up for the shortcomings of traditional power supply technology due to its advantages of high stability,low line loss and long lamp life.This paper compares AC remote power supply and DC remote supply systems,and deeply analyzes the advantages of DC power distribution technology in tunnel lighting.Combined with the tunnel engineering case,the DC centralized drive control lighting power supply technical scheme was proposed.
