摘要(Abstract):
排管敷设是目前电力电缆的主要敷设方式,利用镜像法和叠加原理,建立了排管敷设时电缆载流量的计算模型,运用推导出的公式计算双回和四回排管敷设时每回电缆的载流量,给出了载流量最优的电缆排列方案。
Duct is one of the main laying methods of power cable, A model for calculation of the ampacity of cables installed in ducts is established by the mirror method and superpos ition principle in this paper; by use of deduced formula, ampacity of cables in the double and four-trow ducts is calculated. The paper also puts forward the optimal arrangement scheme of cable.
