In order to further improve the operating efficiency of the heavy oil box-type substation and reduce the construction cost, through the combination of theoretical analysis and simulation calculation method, this paper established mathematical and physical model of box-type substation outflow field, with a box-type substation as the research object.this work numerically simulated thermal equilibrium distribution under different parameters of box-type substation under two kinds of environmental, respectively getting temperature field distribution of the box-type substation under the calm and natural ventilation environment, obtaining by comparative analysis the influence of calm and natural ventilation environment on temperature field distribution.
