Title:
APPARATUS AND METHOD FOR SHIELDING AN ELECTROMAGNETIC FIELD OF A DUAL RAIL POWER SUPPLY SYSTEM FOR AN ON-LINE ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2011/078616
Kind Code:
A2
Abstract:
The invention relates to an apparatus for shielding an electromagnetic field of a dual rail power supply system for an on-line electric vehicle, comprising: a power supply rail buried under a road and extending along the lengthwise direction of the road; a power supply core electrically insulated from the power supply rail and arranged beneath the power supply rail; a power-collecting device to which power is supplied from the power supply rail through electromagnetic induction; and shielding members arranged at either side of the power supply core so as to shield electromagnetic fields generated by the power supply rail and the power-collecting device. According to the present invention, a loop-shaped porous mesh made of SUS materials is buried underground up to a predetermined depth so as to reduce the intensity of electromagnetic fields generated by a power supply/collecting device of the on-line electric vehicle. Thus, electromagnetic fields are consumed, as current, by the loop-shaped porous mesh buried underground, even when the output from the power-collecting device increases, and therefore the level of electromagnetic fields satisfies the reference level 62.5mG, and the number of shielding plates attached to lower portions of conventional vehicles can be reduced.
