MARINE STRUCTURE Russian patent published in 2020 - IPC B63B59/04 H05B33/02 B08B17/02 

FIELD: electrical equipment; shipbuilding.

SUBSTANCE: invention relates to a marine structure comprising outer surface (50), load (2, 20, 25) comprising a light source, wherein said load has a first load terminal (2a) and a second load terminal (2b) configured to be powered from the alternating current power source (1), wherein said AC power supply (1) has first AC terminal (1a) electrically connected to surface (50), and second alternating current output (1b), first electrode (3), electrically connected to first terminal (2a) of load, and dielectric layer (4). First electrode (3) and dielectric layer (4) are configured to form—in combination with surface (50)—capacitor (6) for capacitive power transmission between first electrode (3) and surface (50). Second AC terminal (1b) and second load terminal (2b) are configured to be electrically connected to second outer electroconductive element (10, 11), isolated from surface (50). First load lead (2a) is electrically isolated from second load terminal (2b).

EFFECT: in accordance with invention, use of capacitive principle of electric power transmission is modified and optimized for use, for example, in electric power supply devices for transmission of electric power to light sources installed on that part of ship hull, which is usually under water; in addition, electric circuit is adapted to resist impacts, as well as disruptive surface damages at different levels, such as, for example, opening or short circuit of the UVC light-emitting diode circuit.
