    High-speed train driver with internal overpressure
    The present invention relates to a high speed train power train, of the type comprising a body and at least one traction motor of said body; said box comprising a roof and a floor; the at least one traction motor being disposed under said floor; the box also comprising a technical room defined between said roof and said floor, said technical room comprising: electrical equipment for controlling the at least one traction motor; and at least a first ventilation device for said electrical equipment.
    The invention is particularly applicable to passenger transport. A high-speed train includes one or more drive trains, most often one at each end of the train, and a number of passenger cars.
    In current high-speed trains, the ventilation of the electrical equipment of the power cars is ensured by ventilation holes provided in the side walls of said power cars. The movement of the train generates a flow of air which cools said electrical equipment. However, such a ventilation system exposes electrical equipment to outside dust, humidity, and even snow.
    It is also known, in particular from document US2013 / 0252527, to equip railway power cars with electric fans. Known systems, however, impose constraints on the architecture of the powerplant.
    The present invention aims to improve existing devices, by providing a ventilation system for electrical equipment, while optimizing the quality of the indoor air and making it possible to improve the design of the powerplant.
    To this end, the subject of the invention is a high-speed train driver of the aforementioned type, in which the first ventilation device comprises: a first air intake duct, forming a closed duct between an inlet and an outlet open to the technical room; and a first fan disposed between the inlet and the outlet of said first duct, so as to create an overpressure in the technical room.
    According to other advantageous aspects of the invention, the powerplant comprises one or more of the following characteristics, taken in isolation or in any technically possible combination:
    the inlet of the first sheath is arranged at the level of a first air inlet mouth situated on the roof of the box, and the first ventilation device comprises a first filtration member disposed at the inlet of the first sheath, said first filtration member being permeable to air and capable of retaining solid particles of dimensions greater than a first threshold;
    - The first filtration unit includes deflector elements of the Persiennes type;
    - the deflector elements define air inlet channels arranged in a direction perpendicular to a main direction of movement of the powerplant;
    - The first ventilation device comprises a second filtration member, disposed in the first sheath between the first filtration member and the first fan, said second filtration member being permeable to air and capable of retaining solid particles of larger dimensions at a second threshold, said second threshold being less than the first threshold;
    - The second filtration member comprises a panel of textile material;
    - The first ventilation device further comprises at least one air outlet, located on the roof of the box and in fluid communication with the technical room;
    - the box also comprises at least a second ventilation device separate from the first ventilation device, said second ventilation device comprising: a second air intake duct, forming a closed duct between an inlet and an outlet open to the technical area ; and a second fan disposed between the inlet and the outlet of said duct, the first and second ducts being located close to opposite ends of the body.
    The invention will be better understood on reading the description which follows, given solely by way of nonlimiting example and made with reference to the drawings in which:
    - Figure 1 is a partial longitudinal sectional view of a powerplant according to an embodiment of the invention; and
    - Figure 2 is a cross-sectional view of the powerplant of Figure 1, the left and right parts respectively representing the front and the rear of the technical room.
    FIG. 1 represents a high-speed train power train 10, according to an embodiment of the invention. The powerplant 10 is intended to be assembled with rail vehicles of the passenger transport wagon type, to form a train.
    The powerplant 10 comprises a body 12, as well as two bogies 14, 15 and two traction motors 16, 17, arranged under said body 12. Each traction motor 16, 17 is intended to set in motion the wheels of one of the bogies 14, 15. The powerplant 10 further comprises an electric transformer 18, connected to the traction motors 16, 17 and also arranged under the body 12.
    The box 12 has a roof 19 and a floor 20, which vertically define said box. The bogies 14, 15 and the traction motors 16, 17 are arranged under the floor 20. The box 12 also has side walls 21.
    The body 12 has an elongated shape. We consider an orthonormal base (X, Y, Z), the direction Z representing the vertical. The body 12 mainly extends in the direction X, corresponding to a usual direction of movement of the powerplant 10. The body 12 has a front end, formed by a driving cabin 22.
    A first bogie 14 and a first traction motor 16 are located close to said front end of the body 12. A second bogie 15 and a second traction motor 17 are located near an opposite rear end of the body 12.
    Adjacent to the driver's cabin 22 along X, the body 12 includes a technical compartment 24, also called technical room. Said technical compartment is separated from the driver's cabin 22 by a partition 25. The technical compartment 24 is shown in section in FIG. 1.
    The left part of FIG. 2 shows a cross-sectional view of the body 12, at the front of said technical compartment 24, according to a section plane AA indicated in FIG. 1. The right part of FIG. 2 shows a cross-sectional view of the body 12, at the rear of said technical compartment 24, along a section plane BB indicated in FIG. 1.
    In a plane (X, Z), the technical compartment 24 is delimited by the roof 19, the floor 20 and the side walls 21. The technical compartment 24 has a ceiling 26, which divides it along Z between a lower floor 28 and a upper floor 30. The ceiling 26 marks in particular a limit along Z between the side walls 21 and the roof 19, said side walls 21 being substantially flat and vertical and said roof 19 having a domed shape.
    The lower floor 28 of the technical compartment 24 comprises a central corridor 32 and a plurality of technical equipment, installed on either side of said central corridor near the side walls 21. Said technical equipment will be described below.
    Advantageously, the central corridor 32 has a width along Y of between 500 mm and 750 mm, preferably equal to approximately 750 mm. This width is determined to allow comfortable passage for an operator, without significantly limiting the volume available for the powerplant equipment.
    The lower stage 28 of the technical compartment 24 comprises at least one traction box 33. Said traction box 33 comprises electrical and / or electronic equipment for controlling the traction motors 16, 17.
    The lower stage 28 of the technical compartment 24 comprises at least a first ventilation device 34. Said first ventilation device 34 allows fresh air to be blown inside said lower stage 28, in particular in order to cool the electrical equipment. and / or electronic of the at least one traction box 33.
    The first ventilation device 34 is disposed substantially at the front of the technical compartment 24, near the first bogie 14. Preferably, the lower stage 28 further comprises a second similar ventilation device 35, disposed substantially at the rear of the technical compartment 24 near the second bogie 15 and the second traction motor 17. The first 34 and second 35 ventilation devices are visible in FIG. 2. The description below also applies to the first 34 and to the second 35 device ventilation, the elements common to said devices being designated by the same reference numbers.
    The ventilation device 34, 35 comprises an air intake duct 36. Said duct 36 forms a closed duct, with the exception of an inlet 38 and an outlet 40.
    The inlet 38 of the sheath is arranged at the level of the roof 19 of the body 12. More specifically, the inlet 38 is formed by a first air inlet mouth 41, incorporated into the roof 19.
    From inlet 38, the sheath 36 extends into the upper floor 30 of the technical compartment 24, crosses the ceiling 26 and continues until the outlet 40, arranged in the lower floor 28.
    The ventilation device 34, 35 further comprises an electric fan 42, located in the lower stage 28 at the outlet 40. The fan 42 is capable of blowing air outside the box 12 in the lower stage 28, so as to create a slight overpressure inside said lower stage.
    The ventilation device 34, 35 further comprises a first filtration member 44, disposed at the inlet 38 of the sheath 36. The first filtration member 44 is permeable to air and capable of retaining solid particles of dimensions greater than one first threshold. As an indication, said first threshold is between 80 micrometers and 120 micrometers; typically said first threshold is 90 micrometers.
    Preferably, the first filtration member 44 includes mechanical deflector elements, such as louvers 46. Said louvers 46 define channels 48 which form the inlet 38 of the sheath 36. Preferably, said channels 48 are arranged in the direction transverse Y, or perpendicular to the main direction X of movement of the motor 10.
    The shutters 46 thus make it possible to limit the penetration of drops of water and dust particles into the inlet 38 of the sheath 36, during the movement of the powerplant 10.
    The ventilation device 34, 35 further comprises a second filtration member 50. Said second filtration member is disposed in the sheath 36, between the first filtration member 44 and the fan 42. The second filtration member 50 is permeable to air and capable of retaining solid particles of dimensions greater than a second threshold, said second threshold being less than the first threshold. As an indication, said second threshold is between 50 micrometers and 80 micrometers.
    Preferably, the second filtration member 50 comprises a panel of textile material, or of another air-permeable material, arranged across the sheath 36. The second filtration member 50 is intended to optimally prevent the penetration of dust into the lower floor 28 of the technical compartment 24.
    The ventilation device 34, 35 further comprises at least one air outlet mouth 52, 54, located on the roof 19 of the body 12 and in fluid communication with the lower stage 28 of the technical compartment 24. The overpressure generated by the fan 42 in the technical compartment 24, relative to the outside of the body 12, prevents the penetration of dust by said air outlet mouth 52, 54. As a variant, the air outlet mouth 52, 54 does not have a filter.
    In the embodiment shown in FIG. 1, the body 12 comprises a first 52 and a second 54 air outlet vents, located respectively at the front and at the rear of the roof 19.
    Suction of air from the roof 19 instead of suction from the side walls 21 makes it possible in particular to reduce noise vis-à-vis the outside.
    The technical compartment 24 has at least one opening formed in a side wall 21 and closed reversibly by a door 56. Said door 56 gives access from the outside to the central corridor 32 of the lower floor 28. Preferably, the walls side 21 have no permanently cleared opening. In addition to limiting the pollution of the technical compartment 24, such side walls without opening are more aesthetic and allow more freedom in terms of design.
    With the two ventilation devices 34 and 35, it is possible to operate the fans 42 at reduced speed in order to create a slight overpressure in the technical compartment 24, as described above.
    Furthermore, when the technical equipment of the technical compartment 24 heats the internal atmosphere of said technical compartment, the fans 42 are put into operation at full speed in order to evacuate the calories to the outside.
