<p>PROBLEM TO BE SOLVED: To make it possible to make the line length longer if feed lines of the same breakdown voltage are used and to use smaller primary current or a shorter pickup coil if the same feed capacity is to be obtainted. SOLUTION: Four feeder lines 6a to 6d are arranged parallel each other at a given space along a guide rail for guiding a carrier truck and a feeder line is bent for wiring so that electric currents in the neighboring feeder lines flows in the opposite direction to each other. Two pickup coil units 9, each made up of a core 12 of 'E' shape in cross section and a pickup coil 13 wound onto the center protruding part 12a of the core 12, are mounted onto the carrier truck via a mounting member 11 in such a manner that the pickup coils 13 come to the position between two feeder lines 6a, 6b, 6c, 6d neighboring each other. Both pickup coils 13 are connected in series.</p> |
