CAPACITANCE ADJUSTING DEVICE FOR NON-CONTACT FEEDER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a capacitance adjusting device for a non-contact feeder system capable of adjusting the capacitance of a feeder at a construction site in a non-contact feeder system. SOLUTION: The non-contact feeder system includes: a rail mounted in a fixed manner on a frame side; a movable body guided and supported so as to run along the rail; a feeder cabled along the rail to flow a high-frequency current; and a power receiving unit moving with the movable body and driving the movable body by the current passed from the feeder. The power receiving unit has an electric receiver arranged on the feeder in a non-contact manner and serves as a capacitor box 100 in the non-contact feeder system where electromagnetic induction by a magnetic field generated on the feeder generates an induced current on the electric receiver so as to pass current between the feeder and the power receiving unit. The capacitor box includes: a first connection part 100A connected to a first feeder; a second connection part 100B connected to a second feeder; and a capacitance adjustment part 110 for adjusting a capacitance between the first connection part 100A and the second connection part 100B.
