Title:
WIRELESS POWER TRANSMISSION STRUCTURE OF PORT RTGC COMPRISING MODULAR CURRENT COLLECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/117332
Kind Code:
A1
Abstract:
The present invention relates to a wireless power transmission structure of a port RTGC comprising a modular current collection device and is characterized in that a power supply coil which is a coreless power supply line for power transmission is buried and installed in the ground so as to supply power to the port RTGC, and the modular power collection device comprising an iron core and a power collection coil is provided in the port RTGC such that magnetic energy is converted into electrical energy through interlinkage when magnetic energy of the power supply coil is transferred through a gap in a contactless manner. According to the present invention, a coreless power supply line which does not use a separate core (iron core) is installed on the ground while power is transmitted in a contactless manner by means of a resonance-type electromagnetic induction scheme, and thus durability can be increased and the power supply line be more easily installed.
