Abstract
Provided is a transmission coil which can inhibit reduction in transmission efficiency during underwater non-contact electric power transmission. A transmission coil configured to transmit electric power in water includes an annular electric wire through which an alternating current flows, and a first cover which includes non-conductive resin or non-magnetic resin and seals a periphery of the electric wire. The electric wire transmits the electric power via a magnetic field generated by flowing of the alternating current.
Claims6
A transmission coil configured to transmit electric power in water, the transmission coil comprising:
- an annular electric wire through which an alternating current flows;
- and
- a first cover which includes non-conductive resin or non-magnetic resin and seals a periphery of the electric wire,
- wherein the electric wire transmits the electric power via a magnetic field generated by flowing of the alternating current,
- wherein the first cover includes:
- a second cover which includes a notch formed along a radial direction of the first cover and surrounds an outer peripheral surface of the electric wire in a radial direction with the non-conductive resin or the non-magnetic resin;
- and
- a self-bonding tape configured to seal an outer peripheral surface of the second cover in a radial direction, the self-bonding tape being non-conductive or non-magnetic.
