　　连接金具是输电线路重要的连接承载金具，尽管结构简单，价格低廉，但它的安全可靠直接关系到输电线路的长期安全运行。考虑制造及使用的经济性，目前技术标准对连接金具提出了基本的质量要求。但遇到特殊的线路环境，又对连接金具提出了更高的技术要求，例如我国西北地区750kV特高压输电线路，运行不到两年，在多处大风区域，其U型环发生了大量的严重磨损。所以如何检验金具本事及其组合形式的耐磨损性能就显得尤为迫切。本文旨在介绍通过模拟实际线路环境及承载状况，研制一台用于评估连接金具摆动磨损的试验装置。

Connection fitting is important for transmission line. Although the structure is simple and inexpensive, it directly concerns the long-term safe operation of transmission lines. Considering the economics of the manufacture and use, it puts higher demand on the current technical standard. If the line environment is special, its requirement of connection fitting is higher. For example, the 750kV ultra-high voltage transmission line in the northwest China, it runs less than two years. This paper stimulates the actual line environment and load condition, and develops a test device used to evaluate swing wear of connection fittings.
