“布—也”35kV输电线路24号铁塔倒塔原因与对策探析
Analysis of ‘Bu-Ye’ 35kV power transmission line No. 24 iron tower collapse reasons and countermeasures
【摘要】 作为一种风敏感结构体系,塔—线输电结构在遇到强风条件下容易产生风振,给塔架结构安全性带来隐患,严重时易造成弯塔、倒塔事故。本文对"布—也"35k V输电线路在极端恶劣大风条件下发生的24号铁塔倒塔原因进行了分析,并提出了几种铁塔升级、加固对策,旨在提高输电线路铁塔的可靠性和安全性。
【Abstract】 Tower-line power transmission structure can easily produce wind-induced vibration under the condition of strong wind as a wind-sensitive architecture,thereby bringing hidden danger to tower structure safety,tower can be bended and collapsed in serious condition. In the paper,reasons of No. 24 iron tower collapse in ‘Bu- Ye’35k V power transmission line under strong wind conditions are analyzed,several iron tower updating and reinforcement countermeasures are proposed aiming at improving power transmission line iron tower reliability and safety.
