NONCONTACT ELECTRICITY COLLECTING EQUIPMENT THROUGH ELECTROMAGNETIC INDUCTION SYSTEM USING RECTILINEAR CONDUCTOR AND IRON-CORE COIL

摘要

PURPOSE:To enable the noncontact collection of electricity which is free from the electric wave hindrance by installing a ground side primary coil along a rail and generating an induced electric power in the secondary coil on a train side through the primary side coil and an iron core magnetic path. CONSTITUTION:An elliptical-shaped coil 1 is arranged along a rail, and a secondary winding 3 having an iron core 2 is installed on a train side. The iron core 2 intrudes inside the elliptical-shaped coil 1 of a primary winding, and collects the magnetic fluxes penetrating through the coil 1. In this case, the both edges of the coil 1 are bent with respect to the rail and set free so that the iron core 2 is prevented from collision when the train moves. Therefore, the iron core 2 collects magnetic fluxes, passing through the magnetic field of the rectilinear part of the coil 1, and the secondary winding 3 generates an induced electric power. Therefore, the electric power source on the train can be obtained through the noncontact collection of electricity without installing a special cycle converter, and the electric wave hindrance can be reduced.
