摘要:
针对特高压大跨越输电塔跨越档距大、塔体高且负荷重的特点,从材料选取、导线排列方式、结构动力特性以及风振响应等几个方面对1 000 kV特高压双回路跨越输电塔进行分析,总结了所研究塔型的动力特点,对其风振系数进行了计算和讨论,并根据动力特性分析提出了结构设计中风振系数的取值方法。结果表明:风振系数具有较大的离散性,不同塔身高度应取不同的值进行计算; 该方法为特高压大跨越输电塔的结构设计提供了参考。
Abstract:
Aimed to ultra high voltage(UHV)long-span transmission tower being characterized with long-span, high-rise and heavy load, material selecting, conductor arranging and dynamic characteristic and wind-induced response, 1 000 kV UHV double circuit long-span towers were analyzed. Dynamic characteristics of these kinds of long-span transmission towers were summarized. Wind-induced vibration coefficient were calculated based on the wind load time history response, and according to the analysis of dynamic behavior, a reasonable wind-induced vibration coefficient in construction design was proposed. Results show that wind-induced vibration coefficient has discreteness and different values of coefficients should be chosen according to different heights of towers.The method can provide some references for the design of UHV long-span transmission towers.
