Abstract:
The present invention relates to a cross-segment feed device capable of turning on/turning off individual modules, and more particularly, to a cross-segment power feed device that can turn on or turn off a power feed for each feed module, by modularizing non-contact feed lines for various moving bodies, such as a vehicle, an under-water moving body, or a robot. According to the present invention, one or a plurality of feed modules can be selectively turned on or turned off by controlling a switch that regulates the direction of the electric current flowing through each of the feed modules, without the need to install a common line separately from the feed line in order to supply power to each of the feed modules, thereby reducing the cost for installing the common line and improving EMF problems on paths on which the moving bodies are not being operated.
Abstract:
Disclosed is a magnetic field shielding device of an on-line electric vehicle. More specifically, in order to shield unnecessary magnetic fields generated in a power supply device and a shield device, a magnetic field shielding device for the power supply section and the power collection section of an on-line electric vehicle shields the power collecting device of the power collecting section and the power supply device of a power supply railway line simultaneously. The magnetic field shielding device includes: stainless steel punching plates buried under a road at both sides of the power supply section to be separated from each other by a predetermined distance, and having a structure in which a plurality of perforations are formed; and metal brushes provided at both sides of the power collecting section, formed of one or more twisted steel wires facing the ground surface, and electrically connected to the extension sections of the stainless steel punching plates. Therefore, it is possible to effectively shield the magnetic fields generated in the power supply section by the steel punching plate and the metal brushes which are mounted in the power supply section and the power collecting section of an on-line electric vehicle.
