摘要
高压输电塔-线体系是重要的电力工程设施,其安全性直接影响到电力系统的正常运行,而风荷载是威胁其安全的主要因素之一。因此,确保输电线路在风载作用下的安全性具有十分重要的意义。在简要介绍当前高压输电塔-线体系的发展现状以及近年来风灾引起的输电线路破坏情况的基础上,从输电塔-线体系的分析模型、抗风雨研究、风振控制和风洞试验方面,对高压输电塔-线体系抗风雨的国内外研究现状进行了论述。最后,对输电塔-线体系抗风雨需要进一步研究的问题进行了展望。
Power transmission tower-line system is an important power engineering facility , and its security directly affects the normal operation of the power system .The wind load is considered to be one of the main factors threatening its safety.Therefore, it is very important to ensure its safety under wind load .The paper briefly introduced the current development of power transmission tower-line system and the wind-induced collapses of transmission line in recent years .Then, it was described that the researches on wind-rain resistance of power transmission tower-line system according to analysis model , wind-rain resistance study, wind vibration control and wind tunnel test .Finally, the problems in view of wind-rain resistance of transmission tower-line system for further study were proposed .
