DISTANCE INDICATOR FOR NON-CONTACT TYPED POWER SUPPLIER

摘要

PURPOSE: A distance indicator of a contactless electric power feeder is provided to execute a reliable power feed operation by continuously maintaining a critical distance between a pick-up core on a power supply line and a supporting bar. CONSTITUTION: A power supply line is extended from radio frequency power in order to supply power to a guide vehicle. The power supply line is composed of a lead line having a circular cross-section. A contactless electric power feeder is installed in the guide vehicle. The contactless electric power feeder comprises a pick-up part having two 2 pickup coils and a power receiving circuit. The pick-up part comprises a pickup core which is formed into a magnetic material and the 2 pickup coils which are wound in the pick-up core. Each power supply line is supported by a plurality of supporting bars(54a,54b). A distance indicator(100) is formed in the outer side of one end of the pick-up core.
