Title:
POWER SUPPLY SYSTEM, CONFIGURATION METHOD, AND TRANSPORT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/069914
Kind Code:
A1
Abstract:
The present invention provides a power transmission line which is capable of contactless power supply and communication without the risk of electric shocks to persons nearby, is not affected by the placement of metal pieces in the vicinity thereof, and is not susceptible to contamination by dirt and dust. The power transmission line 1 is provided with an external conductor 102 and an internal conductor 101. A mobile conveying body 600 is provided with a power-receiving electrode and receives power from the power transmission line 1. A direct current transmission wire 2 transmits direct current power to the power transmission line 1. An inverter power source Vi converts the direct current power to alternating current power. A switch SW switches the current conducting state of a power-transmitting electrode on and off. The power-transmitting electrode 103 is connected to the internal conductor 101 via an insertion pin 104. The current conducting state of the power-transmitting electrode 103 is turned on for the portion of the power transmission line 1 where the mobile conveying body 600 is present, and the current conducting state of the power-transmitting electrode 103 is turned off for portions where the mobile conveying body 600 is not present, thereby solving the problem of the present invention.
