Abstract:
      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 transformation 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 fasteners, while the steel constructions, aluminum components and disconnectors were also corroded in varying degrees. The corrosion 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 environment. 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 environment classification and atmospheric corrosion detection site density, to enhance the accuracy of evaluation results of atmospheric corrosion map.
