Embodiment Construction

[0024] figure 1 A schematic front view of a traction box 10 of a railway vehicle according to an embodiment of the invention is shown.

[0025] The tank 10 includes a closed compartment 12 and a vent string 14 . The box 10 also comprises a first electrical equipment part 16 , 17 and a second electrical equipment part 18 arranged in the closed compartment 12 .

[0026] The box 10 further comprises cooling means 20 capable of removing the heat dissipated, in particular in the enclosed compartment 12 by said first 16 , 17 and second 18 parts of electrical equipment.

[0027] The cooling device 20 is arranged in the closed compartment 12 and in the ventilation string 14 .

[0028] Closed cabin 12 through the figure 1 Defined by the cover 22 shown in dotted line. Preferably, enclosure 22 is airtight. Thus, the air present inside said hood 22 is confined within the closed compartment 12 .

[0029] The second electrical equipment component 18 preferably includes elements for wh...
