    摘 要:为了增大载流量和控制电晕放电,高压架空输电线路普遍采用分裂导线结构。由于子导线邻近架设,其温度场间可能存在相互影响,导致导线载流量下降。建立了分裂导线的温度场仿真模型,对子导线间温度场的相互影响进行了计算,得到了子导线间温度场相互影响对分裂导线载流量的影响规律,认为采用单根导体载流量乘以分裂数的方式获得架空输电线路载流量的方式是满足工程实践需要的。

Abstract: To increase the ampacity and reduce corona discharge, bundle conductors are widely used in high voltage overhead transmission lines. Due to the close proximity of sub-conductors, the thermal fields might interfere with each other and led to decrease ampacity of the conductors. This paper established the simulation model of bundle conductors thermal fields and carried out calculation for the interaction effect between sub-conductors thermal fields to obtain the influence rule of bundle conductors ampacity from sub-conductors thermal fields. Adopting single conductor ampacity multiply by split number to get overhead transmission lines ampacity could meet the requirements for engineering practice.
Key words: bundle conductors; thermal field; ampacity
