基于宁波地区加速腐蚀试验环境谱,对输电导线铝单丝进行加速腐蚀试验,统计分析了腐蚀质量损失和腐蚀深度,得到了宁波地区输电导线的腐蚀动力学规律.试验结果表明,年腐蚀质量损失速率在第3年达到最大,而年腐蚀深度速率在第5年达到最大,说明第3年后铝丝的腐蚀主要向深度方向发展.

Based on accelerated corrosion test environmental spectra in Ningbo region, accelerated corrosion test was carried out on aluminum monofilament transmission wires. Corrosion weight loss and corrosion depth was analyzed with statistical method and the corrosion dynamic law of aluminum transmission line in Ningbo region was obtained. The results showed that weight loss based annual corrosion rate achieves maximum in the first three years;depth based annual corrosion rate achieves maximum in the first five years. It was concluded that corrosion development of aluminum wire is mainly in depth direction after three years.
