摘要
弧垂是输电线路架设中的质量控制重点,其观测的精度直接影响线路的运行安全。介绍了输电线路弧垂观测的研究现状,分析了便捷式塔上弧垂观测仪的理论、实践依据及结构功能参数,通过安徽双岭变–安庆三500 kV输电线路工程弧垂观测取得的良好效果,为类似工程提供借鉴。
The sag is the focus of quality control in erection of transmission lines, and the accuracy of sag observation will directly affect the operational safety of the line. The research status of the sag observation of transmission lines is introduced. The theory, practical basis and structural function parameters of the sag observation instrument on the portable tower are analyzed. The sag observation of the Shuangling-Anqing three 500 kV transmission line project in Anhui is good and provide reference for similar projects.
