摘要/Abstract

摘要： 塔线体系断线冲击造成特高压输电线路纵向巨大不平衡荷载。为了研究断线冲击荷载效应,采用初始找形建立塔线体系的等效导线模型,然后分析导线断线的力学特点,提出导线断线的动力模拟。在此基础上通过ANSYS软件对塔线体系断线冲击的导线振动进行了瞬态动力数值仿真,从时、频域角度分析了导线振动的动力特性,结果表明,导线断线冲击效应显著,且冲击能量主要集中于高阶竖向振动。

Abstract: The tower-line system disconnection impact causes a huge longitudinal imbalance load of UHV transmission lines. In order to study the disconnection impact load effects, the equivalent conductor model of the tower-line system is first established through initial form-finding, and then the mechanical characteristics of the conductor break is analyzed to establish the disconnection dynamic simulation model. On this basis, the transient dynamic numerical simulation is carried out with the ANSYS software for the conductor vibration of tower-line system disconnection impact, so as to analyze the dynamic characteristics of the conductor vibration from the time and frequency domain. The results show thatthe impact effect of the conductor break is significant and the impact energy is mainly focused on high-order vertical vibration.

Key words: tower-line system, form finding, impact effect, conductor vibration, ANSYS software
