Abstract

The diploma work fractions into four chapters. The first chapter deals with the issue of the thermal project of low voltage distributor. I am describing the physical parameters, the effects and the cosequences realated to the thermal calculation of low voltage distributor.The second chapter devotes to the sellection of a single component used for the distributor composition. The names and the technical specifications, based on which the thermal project calculation and the checking are made, are briefly followed here. The third chapter engages the calculation of the physical parameters, where the main parameter’s line is drawn by the surface warming of a single componet, futher, the thermal flux of a single componet, and finally, warming of the low voltage distributor inner space. The calcualtions use the simplyfied conditions, having effect on reaching the diploma work target. The last chapter concerns the brief outcome analysis of the calculation and it’s possible accuracy improovment to increase the liability of the distributor.
