Problems solved by technology

[0006] However, this system has the disadvantage of permanently emitting a strong electromagnetic field along the entire orbit, which causes a loss of electrical energy and significant electromagnetic disturbance to the environment in which the system is located
[0008] This system also suffers from the other aforementioned disadvantages of contact power systems and further proves difficult to integrate in an urban environment in an optimal and aesthetically pleasing manner

Embodiment Construction

[0037] figure 1 An example of a system 1 according to the invention is shown schematically and briefly, for supplying transport vehicles T via the ground S. As shown in FIG.

[0038] The transport vehicle T is for example a tram, a subway or any other type of urban transport vehicle. Alternatively, the transport vehicle T is a vehicle operating in suburban areas, such as a high-speed train. The transport vehicle T comprises in particular at least one train, each train comprising at least two carriages joined together.

[0039] The power supply system 1 comprises a component 4 emitting an electromagnetic field to power the transport vehicle T by induction. The launching components 4 are distributed along the running track of the transport vehicle T, between the guide rails 9 of the track.

[0040] The launching part 4 is at least partially buried in the ground S, between the guide rails 9 of the running track of the transport vehicle T, it can be referred to figure 2 . Th...

Abstract

The invention discloses a ground-based electric power supply system (1) for a transportation vehicle (T) and the system includes: a transportation vehicle (T), a plurality of elements (4) emitting an electromagnetic field in order to power the transportation vehicle (T) by induction, the emitting elements (4) being positioned and spaced apart from each other along the circulation track of the transportation vehicle (T), a device (5) for receiving the energy emitted by the plurality of emitting elements (4), borne by the transport vehicle (T), means (6) for electrically powering the plurality of emitting elements (4) selectively, the means (6) being laid out so as to electrically power at least one emitting element (4) when the vehicle (T) is located above said at least one emitting element (4), characterized in that the length (L) of the receiving device (5) measured in the direction of circulation of the vehicle, is greater than the distance (D) which separates two consecutive emitting elements (4) along the circulation track.

Description

technical field [0001] The invention relates to a system and a method for supplying electrical energy via the ground, in particular using induction, for a transport vehicle, in particular a transport vehicle of the tram type. The invention also relates to a method of maintaining and servicing such a system. Background technique [0002] Existing ground power systems allow trolley-type vehicles to intermittently harvest power from the system when a vehicle is detected. [0003] For example, patent applications EP0 979 176, FR2 791 930, EP1 043 187 and EP2 088 025 describe such systems known as "APS (French initials, meaning ground powered)" systems. According to the APS principle, the system consists of a series of contact track sections insulated from each other and a permanent supply line running parallel to the series of sections. Further, switching means are provided for individually and selectively connecting the contact track segments to the wires, in particular so th...
