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^-、SO₂和H₂S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。

关键词 ：沿海变电站, 金属腐蚀, 防腐措施, 大气腐蚀

Abstract：

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^-, SO₂ and H₂S 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.

Key words： substations in coastal area metal corrosion anti-corrosion measure atmospheric corrosion
