摘　　要：为探讨新型导线在1 000 kV特高压电网中的适用性,针对某型号铝包覆新型碳纤维复合芯导线与钢芯铝绞线,依据垂直排列方式的特高压铁塔结构和八分裂导线的布置方法,建立了两种三相八分裂导线模型,通过有限元方法进行数值模拟计算,对比分析了在特高压输电条件下两类导线的电场特性。结果表明,新型碳纤维复合芯导线电学性能不仅满足相关的行业标准,较传统钢芯铝绞线还具有较好的电场强度特性,为新型碳纤维复合芯导线应用于特高压电网提供了依据。To explore the applicability of new types of conductors in UHV power grids,comparison between a new type of aluminum conductor with reinforced core of carbon fiber and the steel reinforced aluminum conductor is carried out.Models of three-phase eight-split according to the structure of the tower with vertical arrangement and the eight-split conductor arrangement method using the two types of conductors were established respectively.The numerical simulation was carried out using the finite element method.The electric field characteristics of the two types of wires under UHV transmission conditions were calculated and compared.The results show that the electrical properties of the new aluminum conductor with reinforced core of carbon fiber does not only conforms to the national standards,but also can be a good substitute for traditional steel reinforced aluminum conductor.The results provide basis for applying the new type of conductors application in UHV transmission lines.
