Research on Concrete Temperature Rise of AC UHV Tower Foundation

This paper researches on the temperature rise of concrete caused by the current divergence when fault current divergence of tower foundation of UHV line happened.Tower foundation model is established based on the thermodynamics finite element analysis theory.The feasibility and effectiveness of the concrete heat simulation is analyzed by comparing the ANSYS simulation with test results.The calculation of maximal temperature rise of concrete on the condition of current divergence of typical vertical four tower bases single pile tower foundation of UHV line shows that the thermal stability of the tower foundation concrete can be guaranteed.
