Due to the significant increase in summer's temperature particularly in Saharan zone (city of Bechar), the electric power substations in medium voltage to the low voltage (MV / LV) installed by electricity and Gas distribution companies (Sonelgaz) undergo additional stress compared to those installed in the north, because of overheating which leads to outages Electric unexpected for consumers
To this end, the present work is to a numerical study of a type of public distribution station which includes a transformer and taking into account the outside temperature measures by the weather station of ENERGARID laboratory.
The objective of this study is to analyze the results of the distribution of temperature, aeration of the position and the flow of air to the interior of the post.
The use of digital Fluent CFD code that is designed to deal with such physical problem.
Thereafter we will also analyze the influence of some key system settings and find the best solutions or propose a new architecture of positions.
