NON-CONTACT TYPE POWER FEEDER SYSTEM FOR MOBILE OBJECT AND PROTECTING APPARATUS THEREOF
First Claim
1. A noncontact type power feeder system comprising a power feeding portion provided along a track way for a mobile object, and a power receiving portion provided in the mobile object, the power feeding portion being opposed face-to-face to the power receiving portion so as to feed a power thereto characterized in that:
- each of the power feeding portion and the power receiving portion is formed of windings formed in an oval shape, and a magnetic planar core formed in its surface with a recess for accommodating therein the windings;
the planar core is formed of an assembly of planer blocks each having a rectangular surface, the assembly of planar blocks comprises thin wall parts in which several planar blocks are laid in one and the same plane with their long sides being made into contact with one another, and thick wall parts in which several planer blocks are superposed one upon another, the recess of the planar core is defined by the thick wall parts in which planar blocks are superposed on the surface of the planar core outside and inside of the oval shape part of the windings,the longitudinal direction of the oval shape of the windings and the long sides of the planar blocks are directed in a travel direction of a mobile object when the power feeding portion and the power receiving portion are opposed face-to-face to each other.

Abstract
A noncontact type power feeder system for feeding a power to a mobile object, in which a power feeding portion and a power receiving portion can be easily manufactured at low costs and which can transmit a high power. The noncontact type power feeder system for a mobile object, comprises a power feeding portion provided in a surface on which the mobile object runs, and a power receiving portion provided in the lower part of the mobile object at a position facing to the power supply portion, the each of the power feeding portion and the power receiving portion is composed of windings formed in an oval shape, and a magnetic planar core formed therein with a recess in which the windings are accommodated so that the longitudinal direction of the oval shape of the windings is extended along the travel direction of the mobile object, the planer core is composed of several planar blocks each having a rectangular surface, several blocks being laid so that long sides of the rectangular surfaces are extended in the travel direction of the mobile object, in which several blocks are also laid in the direction orthogonal to the travel direction, and several blocks being superposed one upon another, the recess of the planar core is defined by thick wall parts in which the planar cores are superposed on the surface of the planar core, outside and inside of the oval shape part of the windings.
