摘　　要：随着电力系统容量的迅速提高和电网规模的不断扩大,电网设备金属部件腐蚀引起的事故时有发生。为了确保电力系统的可靠性,研究人员越来越多地关注到电网设备金属部件的腐蚀和防护。因此,针对接地扁钢、拉线棒、连接金具等典型电网设备金属部件腐蚀的宏观和微观特征进行归纳总结,通过宏观形貌检验、SEM微观形貌分析、EDS能谱分析等手段,分析腐蚀失效行为及机理,并对提高金属部件的防腐蚀性能提出针对性的建议与对策。With the rapid improvement of power system capacity and the continuous expansion of power grid scale,accidents caused by corrosion of metal parts of power grid equipment occur from time to time.In order to ensure the reliability of power system,researchers pay more and more attention to the corrosion and protection of metal parts of power grid equipment.Therefore,this paper summarizes the macro and micro characteristics of metal parts corrosion of grounding flat steel,stay rod,connection fittings and other typical power grid equipment,analyzes the corrosion failure behavior and mechanism by means of macro morphology inspection,SEM micro morphology analysis,EDS energy spectrum analysis,and puts forward some suggestions and countermeasures to improve the anti-corrosion performance of metal parts.
