摘要:
准确了解钢芯铝绞线在温度场中各层线股的应力分布,可为架空导线的安全设计和疲劳分析提供理论依据。根据钢芯铝绞线材料性能和协同变形特点,采用理论分析和有限元模拟研究导线线股应力和温度之间的关系,分析了导线平均温度和径向温差对最外层铝股应力的影响。结果表明,不考虑径向温差时,铝股应力随温度的升高而减小,钢芯应力随着温度的升高而增大;考虑径向温差时,外层铝股的应力随着温差的增大而增大,内部铝股和钢芯的应力随着温差的增大而减小,温差达到20ºc时,外层铝股应力增加49%左右。
Abstract:
An accurate understanding of the stress distribution of each layer of ACSR in the temperature field can provide theoretical basis for the safety design and fatigue analysis of overhead conductors . Based on the properties of ACSR materials and its collaborative deformation characteristics, the relationship between stress and temperature of wire strands is studied by theoretical analysis and finite element simulation. And the effects of average temperature and radial temperature difference on the stress of outermost aluminum strands of aluminum strand decreased with the increase of temperature. While the stress of steel core increase with the increase of temperature; when the radial temperature difference was considered, the outer aluminum strand stress increased with the increase of temperature fifference, and steel core aluminum strand internal stress decreased with the increase of temperature difference. When the temperature reached 20ºc, the outer layer of aluminum stress increased about 49%.
