Application Analysis of DC Technology in Tunnel Lighting
FU Wei
Abstract：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.
