500kV输电线路放线应力弧垂设计校核

Design verification of stress and sag for 500 kV transmission line

本文所编制的设计校核计算程序,只需输入电线参数即可自动求得应力和弧垂。针对某500 kV试验线路开展应力弧垂设计校核,发现地线应力设计错误并进行更正,确保了工程安全。该计算程序可对不同电压等级线路电线进行应力弧垂设计校核。

The method design verification calculation programme is complied,and stress and sag can be automatically obtained after inputting liner parameters. The design verification of stress and sag was carried out for a certain 500 kV transmission line actinomycetes stress sag design verification, and stress design errors was found and corrected by checking ground actinomycetes,which ensures the project safety. The calculation program is suitable for stress and sag design verification of different voltage levels transimission line.
