高湿区域输电线路金具锈蚀多因素影响分析模型

Multi-factor Influence Analysis Model for Corrosion of Metal Fittings on Transmission Lines in High Humidity Areas 

摘要:

对地区污染总体情况以及输电线路金具腐蚀的诱因进行了分析，提出了分析方法以及防护措施。结果表明：四川区域酸性湿沉降主要分布在川南和川西区域，分布在夏秋季节；高硫污染高酸型湿沉降环境，是金具腐蚀速率加快的环境外因；由此建立了输电线路金具锈蚀多因素模型，获取金具区域腐蚀分布图；还提出金具材料防腐、线路图像识别以及输电线路维护等多种防护措施。相关结果为高湿区域输电线路金具锈蚀防护提供了参考。

Abstract:

The overall situation of regional pollution and the inducement of corrosion of metal fittings on transmission lines are analyzed, and the analysis method and protective measures are put forward. The results show that the acid wet sedimentation in Sichuan region is mainly distributed in the south and west of Sichuan, and is distributed in summer and autumn. The high sulfur pollution and high acid type wet sedimentation environment is the external cause of the acceleration of corrosion rate for metal fittings. The multi-factor model for corrosion of metal fittings on transmission lines is established, and the regional distribution map for corrosion of metal fittings is obtained. A variety of protective measures such as anti-corrosion measures for metal fittings, image recognition of lines and maintenance of transmission lines are put forward. The relevant results provide a reference for corrosion protection of meatl fittings on transmission lines in high humidity area.
