ELECTROMAGNETIC SHIELDING DEVICE OF POWER SUPPLY AND POWER COLLECTOR FOR TRANSMISSION OF MAGNETIC INDUCTION POWER

WIPO Patent Application WO/2011/149263

A3

The present invention relates to an electromagnetic shielding device on a power supply line for transmission of magnetic induction power, comprising: a first ground member extending in a straight line on top of the power supply line; and second ground members arranged at regular intervals, crossing the first ground member, wherein the first ground member and the second ground members are connected in a skeleton-type structure. According to the present invention, with the skeleton-type structure ground lines that are installed respectively at a power supply line and a power collection coil of an online electric vehicle, it is possible to avoid any loss in eddy current by magnetic induction during power transmission of the online electric vehicle, to shield electromagnetic waves generated in the power supply line and the power collection coil, and to offer safe protection from high-voltage electricity.
