摘要
对影响110kV和220kV金属氧化物避雷器产品安全运行的关键技术指标做了详细研究。结果表明:整只产品电位分布得到改善,热稳定性裕度较大,机械特性优异,荷电率选取合理,2种产品均可用于Ⅳ级特重污秽地区。
This paper studies in-depth the key technical indexes affecting safe operation of metal oxide surge arrester products on 110 and 220 kV. The results show that the products are featured potential distribution being rationalized, thermal stability margin enlarged, mechanical strength improved and electric charging rate being better selected. These two kinds of products can be used in IV class heaviest contaminated areas.
