Secondly, said rectifying station occupies a far from negligible area and volume, which is sometimes a real dangerous place for engineers in order to find a suitable site
Also, these rectifier stations can be particularly costly considering the generally rising prices per square meter in cities

Embodiment Construction

[0055] [55] Figure 1 shows a configuration of the supply system according to the invention, called a four-track configuration, for a railway vehicle of the tram type. The system comprises an extra-low voltage power supply part 10 installed next to at least one railroad track 20 having two running rails 21, 22 on which the vehicles move.

[0056] [56] Between the running rails, there are two power supply rails 41, 42, which are parallel to each other and parallel to the running rails, wherein the first power supply rail 41 is connected to a connection of the power supply part. The second power supply rail 42 is connected to the other terminal 12 of the power supply component.

[0057] [57] A railway vehicle 30 is run on the railway track, the railway vehicle includes four runners 31 connected to the vehicle. A first electric energy collecting part 51 and a second electric energy collecting part 52 are installed in the railway vehicle, and these collecting parts are placed in m...

Abstract

The line has a low voltage power supply unit (10) supplying average power to a power supply (80) which supplies a storage unit (60) that stores energy. The power supply uses the energy for supplying a traction chain (70) during starting phase or during ascending grade. One of two supply rails is electrically joined with one of two running rails, while the other supply rail is electrically distinct from the running rails. - The power supply uses the electrical energy stored during one of running phase, braking phase where electrical energy is recovered from the traction chain, or stop phase of the storing unit, for supplying the traction chain.

Description

technical field [0001] [01] The present invention relates to an extra-low voltage power supply system for electric traction vehicles loaded with energy storage. Background technique [0002] [02] The ultra-low voltage refers to a voltage on the order of tens of volts, which is opposite to the traditional supply system that supplies hundreds of volts to trams and trolleybuses. [0003] [03] In recent years, trams - supplied by contacting overhead lines - have returned to cities for their many advantages, in particular that they allow high-capacity and regular passenger transport, are located on the surface and No exhaust gas is emitted. [0004] [04] The same is true for electric traction vehicles with tires, such as trolleybuses. [0005] [05] Of course, the advent of contact overhead lines - used to power vehicles - has the following drawbacks: [0006] [06]—Voltages of about 1000V a few meters above the ground in densely populated areas pose a danger, [0007] [07]—obs...
