摘　　要：分析了输变电钢构件的大气腐蚀因素、大气腐蚀分类和不同的腐蚀环境对输变电钢构件腐蚀的影响。介绍了输变电防腐工程中采用的防腐材料和防腐技术,并分析了不同防腐技术在不同环境的耐蚀特点。由于各种防腐蚀材料和防腐技术在不同的腐蚀环境会体现出不同的耐蚀性能,因此,在对输变电防腐工程中应首先对腐蚀环境进行评估,判断腐蚀环境的主要腐蚀因素,根据腐蚀环境特点进行合理选材。The main factors of atmospheric corrosion,the categories of atmospheric corrosion and the impact of different corrosive environment on steel components for power transmission and distribution were analyzed. The anti-corrosive materials and technology used in power transmission corrosion engineering were introduced and the corrosion characteristics of different corrosive ways in different environments were analyzed. Because different protective materials and anti-corrosive technology in different environments will perform different protective properties,during corrosion engineering for power transmission in corrosive environments,protective materials should be selected by corrosive environment evaluating and the main factors analyzing.
