| 摘要 |
<p>A ground power supply line for electric traction vehicles is provided with two conductors (6,7) carried by a series of tiles (21) aligned to one another; each tile (21) has a conductive plate (10) and a lower supporting structure, which is made of insulating material and accommodates electric connectors (43-45), normally open switches (47,48), and a control and command unit (46), which switches the switches (47,48) for selectively electrically connecting the conductive plate (10) to the conductors (6,7) in response to a signal deriving from an electric traction vehicle passing over said external conductive plate (10); the upper surface (11) of the conductive plates (10) is flushed with the remaining part of a road surface.</p> |
