MAGNETIC FIELD SHIELDING DEVICE OF ON-LINE ELECTRIC VEHICLE

摘要

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.
