DEVICE FOR CONTACTLESS TRANSMISSION OF ELECTRICITY AND INFORMATION SIGNALS TO AN UNDERWATER VEHICLE Russian patent published in 2021 - IPC H02J50/10 H02J7/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to devices for contactless transmission of electrical energy to underwater vehicle, which, in particular, is used to charge an electric storage battery installed on underwater vehicle, thus organizing a contactless information channel. In the device, the transformer windings are made in the form of flat disks, and magnetic cores of the primary and secondary parts of the transformer are made in the form of flat ferromagnetic screens, one by one adjacent to the first butt ends of the primary and secondary windings of the transformer, and the second ends of windings, one by one, are adjacent to the inner surfaces of docking walls of the primary and secondary parts of the transformer, each antenna of radio channel is placed in cavity of corresponding flat winding of the transformer, while the design of windings and magnetic shields is made with possibility of giving them the required bend, coinciding with contours of underwater vehicle shell, and when transmitting electricity and information signals, both windings have common axis, the outer docking walls of the cases of the primary and secondary parts of the transformer are adjacent to each other, while the non-magnetic gap between windings has a minimum design value, determined by total thickness of docking walls of the cases of transformer's primary and secondary parts, and the load of the device is the battery of underwater vehicle.

EFFECT: increased reliability of operation and increased transmission power from the primary to the secondary winding of the transformer of the device for contactless transmission of electricity to underwater vehicle and, accordingly, reduced time of charging batteries of underwater vehicle by reducing the distance between windings of transformer while maintaining streamlining conditions of body of underwater vehicle with simultaneous operation of information channel between the primary and secondary parts of the device.
