GROUND LEVEL POWER SUPPLY SYSTEM FOR UNGUIDED VEHICLE Russian patent published in 2019 - IPC B60M1/30 B60M1/36 B60M7/00 B60M1/10 B60L5/38 

FIELD: machine building.

SUBSTANCE: invention relates to power supply lines for vehicles with electric traction. In the method, a ground level power supply system for conductive-type unguided electric vehicles contains a pair of power supply tracks containing a current-carrying conductive path, a neutral conductive path for returning current and a protective conductive path. Said current-carrying conductive path is designed to be electrically connected to a voltage source. Said neutral conductive path is electrically connected to the reference potential, while the neutral conductive path runs parallel to the current-carrying conductive path on its first side. Further, the protective conductive path is connected to the ground potential, while the protective conductive path runs parallel to the current-carrying conductive path on its second side, opposite to the first side. Above system is designed with the possibility of installation in the surfaced portion of a road so that the current-carrying, neutral and protective conductive paths are flush with the surface of the surfaced portion of a road.

EFFECT: improved safety and improved electrical contact with conductive paths.
