摘　　要：基于现场勘查与文献调研,介绍了沿海变电站主要设备的腐蚀状况,分析了不同材质金属构件的腐蚀机理,总结了主要金属构件的现有腐蚀防护措施及其有效性。沿海变电站金属设备的腐蚀与大气中含有较高浓度的Cl^(-)、SO_(2)和H_(2)S等气体密切相关。有针对性地联合应用多种防腐蚀技术,包括材料自身改性、表面处理以及涂覆防腐涂料等,可最大限度地提高变电站金属设备的防腐效果。The atmospheric corrosion status of major metallic equipment used in transformer substations in coastal areas,the relevant corrosion mechanisms and the current anti-corrosion measures are summarized based on on-site inspections and literature survey.It is revealedthat the corrosion of metallic equipment is intimately correlated to the high Cl^(-),SO_(2) and H_(2)S concentrations in the atmosphere of coastal areas.The combination of various anti-corrosion technologies,including material modification,surface treatment and anti-corrosion coatings,may maximize the comprehensive anti-corrosion effect.
