摘要
架空线的应力对架空线弧垂有很大的影响。应力增大弧垂变小;应力减小弧垂增大。本课题首先研究应力的变化对架空线产生的影响规律,并根据实验室的环境条件,提出装置方案,重点研究改变应力以及测量的方法,观测弧垂的方法,并理论分析应力变化引起弧垂变化。依据所提出的实验方案,分析实验测量值与理论值可能产生的误差。
The stress of the overhead lines hanging overhead lines arc has a great influence. Stress increases the sag smaller; stress decreases the sag increases. This topic first studied the effect of stress change on the overhead line, and according to the environmental conditions of the laboratory device program, focusing on changes in stress and measurement method. Observation sag, and the theoretical analysis of the stress changes caused by changes in sag. According to the experimental program, Analysis of possible errors of experimental measurements and theoretical values.
