摘要
介绍了抢修型拉线塔的结构及优点,以±800kV特高压直流线路为例,建立了单柱式拉线塔8拉线方案和加短横担4拉线方案两种抢修塔有限元计算模型,分别进行了受力性能分析,考虑拉线塔几何非线性影响,对比分析了不同拉线塔方案内力、位移,同时对其进行了自振特性对比分析,结果表明两个方案均可行。
This paper introduces the structure and advantages of rush repair guyed tower. Taking ± 800 kV UHV DC line as an example, two kinds of finite element calculation models of single column guyed tower are established, which are eight pulling scheme and adding four short cross arm pulling scheme. This paper analyzes the mechanical performance, considers the geometric nonlinear effect of stay tower, and compares the internal force and displacement of different stay tower schemes. At the same time, the comparison and analysis of its natural vibration characteristics show that the two schemes are feasible.
