PROPELLANT ELECTRICAL INSTALLATION Russian patent published in 2020 - IPC H02J3/34 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. For unstressed connection (for "soft start-up") in all powerful matching transformers, which are available in GEM, there should be magnetizing windings with power of not more than 0.5 % of rated power of transformer. Transformation coefficients and magnetizing windings connection groups should be the same as those of the transformer used to power ship-to-ship consumers. Connection of all matching transformers is carried out in turn by one device including low-voltage three-phase AC voltage regulator, input of which is connected to buses of low-voltage switchboard by means of switch, and a switch unit connected to the controller output for connection of AC voltage controller output to magnetizing windings of all matching transformers.

EFFECT: invention can be used in creation of electric installations of vehicles with limited capacity of power supply in cases when the electrical installations include several powerful matching transformers, at direct connection of which to the mains the starting currents considerably exceed settings of current protections.
