Summary on Atmospheric Corrosion and Protection Measure of Steel Components and Galvanized Components for Transmission and Distribution Projects

介绍了电网输变电钢结构和镀锌构件在不同大气环境中的腐蚀情况与腐蚀特点，与大气腐蚀等级划分的一些方法和用于输变电钢结构的常用的防腐蚀措施，并对不同防腐蚀措施做了简单评价，发现不同大气环境会对防腐蚀措施的保护效果有很大影响，所以需要因地制宜结合不同区域的大气腐蚀性，综合考虑各种因素，科学制定电网钢结构设施防腐蚀方案。

The corrosion condition and corrosion characteristics of transformation steel structure and galvanized component for transmission and distribution projects in different atmospheres were introduced. Subsequently, some methods of atmospheric corrosion classification and the com- mon corrosion protection measures for transmission and transformation steel structures were introduced. As a supplement, the simple evaluation of different corrosion prevention measures was proceeded. Furthermore, it was found that the different atmospheric environment would have a great influence on the protective effect of anti- corrosion measures. Therefore, it was necessary to combine the atmosphere corrosiveness of different regions according to local conditions and consider various factors synthetically for making the corrosion prevention schemes on the steel structures and facilities of the power grid.
