Based on the heat conduction equation, fluid flow governing equation and radiation heat transfer equation, the multi-physics coupled mathematical model is established, the convection heat transfer problem between solid and fluid is solved by wall function, the three dimensional thermal and fluid fields of 27.5kV GIS which is used in the distribution system of high-speed railway are calculated and analyzed by the finite volume method. The result shows that the three-position isolation switch in the GIS is the hottest. The computed temperature rises have good agreement with the tested ones; it can prove that this mathematical model and numerical method are reasonable. |
