摘要
城市道路照明系统为强电系统,供电线路通过箱式变压器低压侧、地下线管进入灯杆后给灯具供电。因箱式变压器与灯杆布置在行人道一侧,一旦发生线路漏电现象将造成行人触电伤亡的危险。本文尝试以相关行业标准要求为基础,结合对漏电保护器在道路照明系统的实际应用经验,给出针对城市道路照明系统下的漏电保护器的设计、选型与应用论证,为行业设计及应用维护人员提供应用参考,目的是使其在保障城市道路照明的持续性工作的同时,为市民提供安全可靠的城市道路照明系统。
Urban road lighting system is a high-power system. The power supply line supplies power to the lamp after entering the lamp pole through the low-voltage side of box transformer and underground pipeline. Because the box transformer and lamp pole are arranged on the side of the pedestrian walk, once the line leakage occurs, it will cause the risk of pedestrian electric shock casualties. Based on the requirements of relevant industry standards and combined with the practical application experience of leakage protector in road lighting system, this paper presents the design, selection and application demonstration of leakage protector in urban road lighting system, and provides application reference for Industry Design and application maintenance personnel. The purpose is to ensure the continuity of urban road lighting work while at the same time provide reliable and safe urban road lighting systems.
