摘　　要：目的 了解山东省辖属输变电设备的大气腐蚀现状,衡量大气腐蚀图技术对输变电设备大气腐蚀评价的准确性。方法 通过实地调查的方式开展山东省典型大气环境下输变电设备腐蚀与评价现状的调研。结果 变电设备中,壳体、箱体的腐蚀案例最多,其次是变压器和紧固件,钢构支架、铝合金构件、隔离开关等也发生了程度不一的腐蚀。输电设备的腐蚀主要集中于输电杆塔与紧固件。对比发现,动态大气腐蚀图评价结果与现场调研获得的腐蚀评价结果一致性高,受制于微环境的影响,仅局部预测结果出现偏差。结论 应提高沿海地区、化工密集区域大气腐蚀检测站点的布点密度,改善大气腐蚀图在局部高腐蚀性区域的成图准确性,并从金属材料腐蚀特性、大气环境分类及大气腐蚀检测站点密度等方面综合优化大气腐蚀检测的精度,以提升大气腐蚀图评价结果的准确性。The work aims to study the atmospheric corrosion status of power transmission and transformation equipment in Shandong province and measure the accuracy of atmospheric corrosion evaluation of power transmission and transformation equipment by atmospheric corrosion map technology.The corrosion and evaluation status of power transmission and transfor-mation equipment was investigated in typical atmospheric environment of Shandong province through field survey.It was found that in the substation equipment,the corrosion cases of the shell and box were the most,followed by the transformers and fas-teners,while the steel constructions,aluminum components and disconnectors were also corroded in varying degrees.The cor-rosion of transmission equipment mainly focused on transmission towers and fasteners.By comparison,it was found that the evaluation results of dynamic atmospheric corrosion map were in good agreement with the corrosion evaluation results obtained by field investigation,while the corrosion prediction results in local areas were deviated due to the impact of the actual envi-ronment.It is shown that the accuracy of atmospheric corrosion map should be improved by increasing the distribution density of atmospheric corrosion monitoring points in coastal and chemical intensive areas.In addition,the accuracy of atmospheric corrosion detection method should be improved from the aspects of corrosion characteristics of metal materials,atmospheric en-vironment classification and atmospheric corrosion detection site density,to enhance the accuracy of evaluation results of at-mospheric corrosion map.
