摘要

In this paper, the transfer matrix of lumped parameters is established by the finite element calculation to reflect the thermal characteristics around the cable. It can adapt to different heat dissipation conditions, so as to realize the fast calculation of steady temperature rise for multi-circuit cables with multi boundary conditions under different working conditions, which provides ideas for future studies of fast algorithms of transient temperature rise calculation as well.
