| Abstract: | Based on heat transfer theory,the heat balance relationship of single-circuit gas insulated transmission lines （GIL） with horizontal layout is established in this paper.The calculation formulations of the convective and radiation heat on the tank and conductor surfaces of each phase in the GIL are given.An iteration method of GIL temperature calculation is designed,which is used to calculate the steady-state temperatures of the GIL under different load currents.The proposed method is proved to be effective by the results comparison with that of the finite element method （FEM） and will provide reference for thermal parameter analysis in the design and operation processes of GIL. |
