摘 要:随着城市道路发展,路灯杆运行多年后,逐渐老龄化,但尚未达到更换年限,已无法满足新标准下的路灯正常运行模式。为了降低路灯杆接地电阻值,采用传统降阻值方式下,耗费时间、物料、人力。借鉴移动设备接地电阻的临时接地方式,采用一种新的接地组合方式降低灯杆接地电阻,安装便捷,此方式无须办理掘路手续。With the development of urban roads,street lamp poles are aging after many years of operation,and have not reached the replacement period.Under the old standard,the normal operation mode of street lamps under the new standard can no longer be met.In order to reduce the grounding resistance of street lamp poles,it is ime-consuming,material-consuming and manpower-consuming to adopt the traditional resistance reduction method.Based on the temporary grounding method of mobile equipment grounding resistance,a new grounding combination method is adopted to reduce the grounding resistance of light poles,which is convenient to install.This method does not need to go through the road excavation procedures.
