某330kV输电线路铁塔利旧分析

Analysis on the Use of Original Tower of a 330kV Transmission Line

针对新建输电线路工程中存在的铁塔利旧问题,分析了新建工程的气象条件和导地线型号与原有铁塔的设计使用条件不一定完全相符的工程设计条件。通过按新设计条件验算、校核,得出对原有塔型不能铁塔利旧,以防止出现以小带大的情况,给工程安全带来隐患。

Aiming at the problem of reusing the original tower in the new transmission line construction,this paper analyzes the engineering design conditions that the meteorological conditions of the new project and the model of the ground wire are not necessarily consistent with the design and use conditions of the original tower.Through checking and checking according to the new design conditions,it is concluded that the old tower can not be used for the original tower type,so as to prevent the situation that the small one leads to the large one and bring hidden danger to the engineering safety.
