浅谈城市照明系统剩余电流保护

On Leakage Current Protection of Urban Lighting System

城市照明配电系统不管是采用TT系统还是TN-S系统,都存在单个路灯发生漏电的可能性,并且一旦发生单个路灯漏电,就会导致此控制箱所控制的所有路灯将跳闸熄灭,大大提高了检修的难度。针对该问题,介绍了城市照明配电系统的剩余电流保护措施。以MAGTRON的B型漏电漏电流传感器为例,在城市照明配电系统单根路灯中进行加装。结果显示,可提升城市照明配电系统的安全性和可靠性。

Whether using TT or TN-S systems,there is a possibility of individual street light leakage in urban lighting distribution systems.Once a single street light leakage occurs,it will cause all the street lights controlled by this control box to trip and extinguish,greatly increasing the difficulty of maintenance.In response to this issue,residual current protection measures for urban lighting distribution systems were introduced.Taking MAGTRON's B-type leakage current sensor as an example,adding it to a single street lamp in the urban lighting distribution system shows that it can improve the safety and reliability of the urban lighting distribution system.
