Title:
FEEDER SYSTEM, AND CARRIER VEHICLE AND SYSTEM
Document Type and Number:
Japanese Patent JP3505618
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a feeder system that prevents an overcurrent from flowing to a load, prevents a circuit element from being damaged and burned by the overcurrent generated in a pickup coil and that generated in a resonance capacitor, can display abnormality, and can remotely control the supply of power, and carrier vehicle and system.
SOLUTION: In this feeder system, having the pickup coils L1 and L2, a rectifying circuit 4, and output terminals U and V, relays R1 and R2 are connected between the output-side terminal of the rectifying circuit 4 and the output terminals U and V; the connection between the pickup coils L1 and L2 and relay coils r1 and r2 is made; and power is obtained from the output-side terminal of the rectifying circuit 4, thus providing a protection circuit (switching control circuit) 6 for turning on and off the relays R1 and R2 according to the voltage across the pickup coils L1 and L2.
