摘要
针对接地引下线和接地网的不同腐蚀环境,分析金属腐蚀的机理和影响因素,分别给出大气腐蚀和土壤腐蚀的防护措施。并结合输电运维中心的实际情况,探讨接地网断点和腐蚀的检测与诊断、直升机巡视腐蚀缺陷的识别以及特高压直流输电线路对邻近500kV线路接地装置的影响。
Based on different corrosion environment of grounding down wires and grounding grids,this essay analyzes the mechanism and influencing factors of metallic corrosion as well as giving protective measures for atmospheric and soil corrosions.Moreover,this essay also discusses about the detection and diagnosis of grounding grid breakpoints and corrosions,helicopter corrosion recognition and the influence of the UHVDC transmission line on adjacent 500kV grounding device.
