摘要 针对特高压输电线路中导线性能及输电能力的需求,以铝包覆结构的新型碳纤维导线为研究对象,建立新型导线与传统碳纤维导线的三维物理模型,采用有限元方法进行模拟计算,并分析比较了两种导线在抗拉性能、抗压性能等方面的力学特性。对比结果表明:在径向压力或轴向拉力作用下,相较于普通碳纤维导线存在的应力集中现象,新型导线的应力分布更为均匀,且在两种典型工况下的最大应力均小于传统导线;另一方面,两种碳纤维导线在不同工况下的形变分布基本一致。综合分析表明,新型铝包覆碳纤维复合芯导线能有效提升导线的抗压能力与抗拉能力,具有良好的力学性能。 Aiming at the requirements of conductor performance and transmission capacity in UHV transmission lines,a new carbon fiber conductor with aluminum coating structure is taken as the research object.The three-dimensional physical model of the new conductor and traditional carbon fiber conductor is established.The finite element method is used to simulate the mechanical properties of them.And the properties of the two wires in terms of tensile properties and compressive properties are analyzed and compared.The results of comparative analysis show that under the action of radial pressure or axial tensile force,the stress distribution of the new conductor is more uniform than that of the ordinary conductor with the stress concentration,and the maximum stress is less than that under the two typical conditions.On the other hand,the deformation distribution of the two carbon fiber wires under different working conditions is basically the same.The comprehensive analysis shows that the new aluminum-coated carbon fiber composite core wire can effectively improve the compressive and tensile strength of the wire and has good mechanical properties.
