摘要(Abstract)：

随着分裂导线的应用越来越广泛,线路容量的问题越发不可忽视。然而,分裂导线载流量计算与单根导线存在一定的差异,无法依据现有的导线载流量计算公式得到结果。通过分裂导线的载流量试验,模拟分裂导线实际运行,使用量纲分析,对分裂导线的集成载流量进行研究,得到了在实验室环境下分裂导线的实际载流量值,得出了分裂导线集成载流量与单根导线载流量的数学关系,为线路设计和改造提供了有力的技术支撑。
With the extensive application of bundled conductor, the problem of line capacity cannot be ignored. However, there are some differences in current-carrying capacity calculation between bundled conductor and a single conductor. The current-carrying capacity of bundled conductor cannot be calculated by the existing calculation formula. This paper simulates the actual operation of bundled conductor by current-carrying capacity test and uses dimensional analysis to investigate the integrated current-carrying capacity of bundled conductor. The research obtains the actual current-carrying capacity in the laboratory environment and mathematical relationship of the current-carrying capacity between bundled conductor and a single conductor,providing a powerful technical support for design and reconstruction of lines.
