Problems solved by technology

[0010] This type of power supply system, although aesthetically attractive, does not have a short response time and requires the provision of moving elements, namely elastically deformable strips, which are prone to a large number of failures

Embodiment Construction

[0036] Figure 1 shows an example of how the system of a ground powered electric vehicle 10 may be installed.

[0037] In the illustrated embodiment, the vehicle 10 consists of a public transport vehicle, in particular a tram.

[0038] However, it should be understood that the invention is also applicable to any type of electric vehicle, such as a private car, electric bus or rail vehicle.

[0039] In the illustrated embodiment, the vehicle 10 travels along a road 12 provided with a vehicle-guided travel track 14 .

[0040] These tracks may be omitted if the vehicle 10 is provided with guide wheels which are conveniently fitted with tires.

[0041] A high voltage supply rail 16 , for example 750 V, intended to supply electrical energy to the electric motor of the vehicle 10 , extends longitudinally along the road 12 so as to be central with respect to the rail 14 , that is to say along the longitudinal center axis of the vehicle 10 .

[0042] The power rail is intended to wor...

Abstract

The ground feed for an electric rail vehicle has conductor segments (16A-D) which are insulated from each other and which are contacted by a slide shoe (32) for current feed to the vehicle. High voltage feeds are connected to each conductor segment and switches (45) are used to cause flow to each segment when the shoe is in contact with it. The switch assembly has circuit breakers (T1, 2) controlled by sensors (44) to detect shoe contact.

Description

technical field [0001] The invention relates to a system for powering electric vehicles, in particular electric rail vehicles, via the ground. [0002] It also relates to an electric vehicle powered by means of such a system. [0003] The expression "system for supplying electricity via the earth" should be understood as meaning by means of which the electric energy required to be supplied to the motor of the vehicle is conveyed through segmented conductive tracks on which the road on which the vehicle is driven is equipped with segmented conductive tracks, the conductive track The energized section is covered at all times by the outline of the vehicle, unlike a power supply system using an overhead line network to which a current is applied to a pantograph. Background technique [0004] Power supply systems using overhead lines have a number of unacceptable drawbacks, in particular related to aesthetic appearance, which make them unsuitable for powering vehicles intended t...
