Auxiliary device for the transport of an electric current for the supply of electrical equipment under - marine transport system, the installation of electrical power supply and the associated electric supply

摘要

This auxiliary device (44) of the transport of an electric current to the supply of electrical equipment in a marine - (12), is coupled to a main device (42) for transporting electric current. The main device (42) comprises the primary electrical conductors (46, 47, 48) connected to a supply source (14, 18), of the secondary electrical conductors (52) connected to the equipment under - in the sea, and an electrical transformer (54) comprising a primary winding (56) connected to the primary conductors and a secondary winding (58) connected to conductors secondary. The auxiliary device (44) comprises at least one auxiliary electrical conductor (60) and, for each conductor, a member (62) of the auxiliary electrical coupling of the conductor to a primary conductor is associated, each conductor is connected to the equipment under - marin, each coupling member being adapted so that, on the basis of a current flowing in the primary conductor (46), to inject a direct current on the conductor to the auxiliary equipment in a marine -.
