DEVICE AND METHOD FOR REDUCING LOSSES WITH NON-CONTACT TRANSMISSION OF ELECTRIC ENERGY Russian patent published in 2018 - IPC H02J50/10 

FIELD: electrical engineering.

SUBSTANCE: use in the field of electrical engineering for the non-contact transmission of electrical energy to a subsea subject from a source located on a carrier vessel. Device for reducing losses in the non-contact transmission of electrical energy contains a transformer with a detachable core consisting of two elements, around the poles of which the primary and secondary windings are wound, one element of the core belongs to the carrier vessel, and the second belongs to the submersible. Elements of the core are V-shaped, conically expanding in the interaction zone of the core elements, while the core is isolated from water by a thin waterproof and gas-tight film. Housings of the primary and secondary winding are made in thin-walled design and filled with an electrically insulating heat-conducting damping liquid, wherein housing of the primary winding contains shock absorbers in the form of springs.

EFFECT: technical result is to provide a minimum of losses and high efficiency in the transmission of energy, to eliminate the falling voltage-current characteristic, which is characteristic for transformers with a gap, reducing the material capacity of the device and providing heat removal to the external environment.
