Abstract:From the point of view of conductor force, this paper first analyses the basic principle of conductor force, which is divided into basic data such as conductor specific load and meteorological area. Secondly, it carries out line analysis, conductor stress and spacing distribution, including calculation of data such as representative spacing and critical spacing. Finally, it analyses the importance of conductor force to the selection of overall overhead lines, including cable, foundation, fittings, and so on. Based on the analysis of conductor force, the importance of conductor force calculation for the overall calculation of overhead lines in distribution network is clarified, and the safety and economy of overhead lines design in distribution network are ensured. The mechanical principle in the process of overhead lines design and laying is preliminarily understood by designers and constructors, and the structural calculation is done for the optimization of line design and safe construction.
