- Abstract
Temperature and ampacity of cables are obtained by calculating the Standard model of IEC 60287 familiarly. However, It is difficult to calculate the ampacity of cable laying in tunnel precisely by using traditional computing model with complex structure, variable environment of cable tunnels. Thence, the paper establishes the calculation model of ampacity of cable in the tunnel based on finite element method, and solved it by Ansys Workbench. According to the calculation results of temperature field of cable tunnel, the ampacity of cable can be estimated. Moreover, the relationship between the convective heat transfer coefficient on cable surface and ampacity of cable is analyzed. This paper is significant to improve the reliability of cable in the tunnel.
