特高压大跨越酒杯塔因其较大的塔头尺寸、特殊的曲臂结构,使得该类铁塔的组立工程相比一般铁塔的组立施工,难度更大、要求更高。为保障此类铁塔组立工程的安全高效开展,本文以某1000kV单回路大跨越酒杯型钢管塔为研究对象,建立模块化铁塔有限元模型,对组立至不同状态时的铁塔结构进行模态分析,获取其固有力学特性;考虑高度对风速的影响,对铁塔风荷载进行精确计算,研究风荷载及重力荷载共同作用下不同组立状态时铁塔结构的力学特性。结果表明:整塔的前6阶振型主要表现为塔头及塔身弯曲和扭转的特点,且随着铁塔组立高度的增加 ...

分析下击爆流作用下输电线路的风偏响应对于线路安全运行至关重要。本文通过建立21种不同导线长度、24种不同类型绝缘子串的输电铁塔-导线-绝缘子串耦合数值模型,对这些模型分别输入不同高度、不同水平距离的下击爆流风场,分析这些输电线路在不同下击爆流作用下的风偏响应。研究结果表明:在27m/s设计风速下,考虑下击爆流影响时绝缘子串处的风偏角与不考虑之比在1.34-2.75之间;随着导线及绝缘子串自振频率的增大,风偏角变化均呈现正太分布规律,其最大反应发生在导线及绝缘子串自振频率0.34-0.42Hz之间 ...
