    Railway vehicle with electrodynamic braking
    The present invention relates to a railroad vehicle with electrodynamic braking of the type comprising: - a first and a second car each comprising a body, - a power chopper carried by the first car, - a rheostat carried by the second car, - means of electrical connection between the power chopper and the rheostat, and common mode protection means.
    The electrodynamic braking in a vehicle with an electric motor is ensured, during the braking range, by the connection of the electric motor, acting as a generator, to a dynamic brake. This dissipates into heat in resistors a part of the kinetic energy of the vehicle during the braking phase, transformed into electrical energy.
    In a railway vehicle with several cars, the trunk and the dynamic brake can be located in successive cars, so that an electrical connection ensures their connection to the passage between two cars.
    The link between the trunk and the dynamic brake is generally provided by shielded cables, the shield of which is connected at its ends to a mass of the trunk and a mass of the dynamic brake. Thus, the shielding avoids the electromagnetic radiation of the cables.
    One of the technical problems that arises is the degradation of the connection of the shielding of the cables to the masses. Indeed, during their use, such shielded cables are degraded by mechanical wear and corrosion. The shielding of the cables is no longer connected to ground at both ends and the electromagnetic protection loses its effectiveness as the common-mode currents are no longer looped by the shielding of the cables. As the trunk and the dynamic resistors are not located on the same car, the area between the two vehicles is then subjected to a magnetic field of an intensity incompatible with the required protection standards.
    However, this zone is, in most trams for example, a passage corridor allowing full intercirculation between cars of the train. This defect thus exposes the passenger dangerously to the radiation of an electromagnetic field putting his safety at risk.
    The object of the invention is to provide a rail vehicle with electrodynamic braking improving the service life of the connection between the trunk and the dynamic brake. For this purpose, the subject of the invention is an electrodynamically braking railway vehicle of the aforementioned type in which the electrical connection means between the power chopper and the rheostat comprise at least one electrical phase conductor and the common mode protection means. comprise at least one ground-conducting electrical conductor running along the or each electrical phase conductor, each ground-conducting electrical conductor comprising two ends electrically connected respectively to a power chopper ground and a rheostat ground .
    According to particular embodiments, the invention has one or more of the following characteristics, taken separately or in any technically possible combination: the first car comprises a traction box integrating the power chopper and the second car comprises a metal frame supporting the rheostat, and in that the traction box and the metal frame are electrically connected to the body of the car carrying them, - each electrical conductor of mass support connects the crates of the first and second cars, the first car comprises a trunk box incorporating the power chopper and the second car comprises a metal frame supporting the rheostat, and in that each electrical conductor of mass support connects the trunk of the trunk to the metal frame which each form a mass, - each electrical conductor of mass accompaniment is a Metallic sse or an electric cable, - the distance separating each electrical phase conductor from each electrical ground conductor is less than 1 m, preferably to 50 cm, - each phase electrical conductor and each accompanying electrical conductor of mass form a beam, - each electrical phase conductor comprises at least one cable consisting of a conductive core covered with an insulating sheath, - each phase electrical conductor is devoid of electrically conductive shielding, - the rail vehicle is a tramway . The invention will be better understood with the aid of the description which follows, given solely by way of nonlimiting example and with reference to the appended drawings, in which: FIG. 1 is a plan view of a train trolley according to the invention equipped with an electrodynamic braking device according to the invention; and FIG. 2 is a schematic representation of the connection means and the common mode protection means of the electrodynamic braking device of FIG. 1, according to a first embodiment of the invention.
    The vehicle 10 of FIG. 1 is a tramway train comprising several successive cars 12 articulated to each other. Cars include a body 14 carried by wheels.
    The driving cars comprise an electric motor (not shown) suitable for ensuring the movement of the vehicle. The motor is connected for its power supply to a power chopper 16 contained in a traction box 18 installed on the roof, for example, in the same car as that of the engine.
    The power chopper 16 is adapted to vary the speed of the engine that sets the car of the train.
    The power chopper 16 has a mass formed by the trunk 18. By mass is meant in particular electrical mass.
    The trunk 18 is advantageously electrically connected to the body 14 of the car carrying the trunk 18.
    A rheostat 20 is installed on a metal frame 22 fixed on the roof of the car adjacent to the car comprising the trunk 18.
    The rheostat 20 also has a mass formed by the metal frame 22.
    The metal frame 22 is advantageously electrically connected to the body 14 of the car carrying the metal frame 22.
    The rheostat 20 is electrically connected to the power chopper 16 to dissipate heat the electrical energy produced by the engine in the braking phase.
    As illustrated in FIG. 2, the electrodynamic braking device comprises means 24 for connecting between the power chopper 16 and the rheostat 20. The connection means 24 are phase electrical conductors 26. They are, for example, formed of one or more electric cables each consisting of a conductive core covered with an insulating sheath. The connection is provided by a number of cables between 1 and 5 and advantageously equal to 4.
    The phase electrical conductors 26 are devoid of electrically conductive shielding.
    The electrodynamic braking device also comprises common mode protection means 28 whose purpose is to improve the electromagnetic compatibility (EMC) performance of the connection means 24 by ensuring the equipotentiality of the constituent elements of the braking device.
    The common mode protection means 28 consist of one or more grounding electrical conductors traveling in proximity to the phase electrical conductors 26.
    Each electrical conductor of ground support is devoid of electrically conductive shielding.
    Each electrical conductor of mass accompaniment is, for example, a metal braid or an electric cable.
    In the first embodiment of the invention presented in FIG. 2, each electrical conductor of ground support connects the mass of the power chopper to the mass of the rheostat, that is to say that it connects in particular the trunk box 18 to the metal frame 22. In other words each electrical conductor of mass support connects the electrical ground of the power chopper to the electrical ground of the rheostat.
    In the first embodiment of the invention, each electrical conductor of ground support is connected at one end to the trunk 18 containing the power chopper 16 and at the other end to the metal frame 22 supporting the rheostat 20 .
    In a second embodiment of the invention, not shown in the figures and generally identical to the first embodiment, each electrical conductor of ground support is connected at one end to the body 14 of the car carrying the trunk 18 and the other end on the body 14 of the car carrying the metal frame 22 and provides electrical bridging between the boxes 14.
    In the second embodiment, the trunk 18 is advantageously electrically connected to the body 14 of the car carrying the trunk 18 and the metal frame 22 is advantageously electrically connected to the body 14 of the car carrying the metal frame 22 .
    In both embodiments, each electrical conductor of mass accompaniment travels as close as possible to the phase electrical conductors 26 and advantageously along the entire length of the electrical phase conductors. Advantageously, the electrical conductors of mass support and the electrical conductors of phases form a beam between the boxes 14.
    Advantageously, the phase electrical conductors 26 and the mass accompanying conductors 28 are positioned at a height greater than 80%, preferably greater than 90% of the height of the boxes 14.
    Advantageously, the distance separating the conductors 26 from the ground conductors 28 is less than 1 meter, preferably 50 cm and more preferably 20 cm.
    The close presence of phase 26 conductors and ground conductors helps to ensure the effectiveness of EMC protection and avoid the return of common modes by the streetcar floor.
