DEVICE FOR ELECTRIC POWER SUPPLY OF UNDERWATER FACILITY FROM SHIPBOARD CARRIER Russian patent published in 2019 - IPC H02J3/02 B63G8/00 

FIELD: electrical engineering.

SUBSTANCE: invention is related to electric engineering, namely to devices for power supply of underwater objects along communication line. Device comprises a controlled rectifier mounted on the carrier vessel, the input of which is connected to the ship electrical network, a communication line with the underwater object, secondary power sources on underwater facility, computing device, communication line current measuring transducer, communication etched line length measuring transducer, as well as communication line temperature transducers onboard carrier vessel and temperature of etched part of communication line in water. At that, the current measuring transducer is connected to the communication line supply wire breakage, at that the signal from its output, as well as information from outputs of measuring transducer of etched part of communication line length and from outputs of measuring transducers of temperature of communication line on board carrier vessel and temperature of etched part of communication line in water is supplied to inputs of computing device, wherein the output of the computing device is connected to the control input of the controlled rectifier.

EFFECT: technical result consists in implementation of a device providing maintenance of constant voltage value at inputs of secondary power sources on underwater object at change of load in specified limits and increased length of communication line.
