Patent ID: 8829737

Claim:
An electrical network for confined environment designed to transport electric power from at least one electric power source ( 5 ) to several electrical loads ( 4 ): a) comprising a main electrical network ( 1 ) comprising several electric wires ( 10 ) that are electrically insulated from one another, which are able to distribute electric power between a primary distribution assembly ( 2 ) of at least one electric power source ( 5 ) and a secondary distribution assembly ( 3 ) to the plurality of loads ( 4 ); b) in which the primary distribution assembly ( 2 ) for each electric power source ( 5 ) comprises at least one primary distribution subassembly selector means ( 20 ), which selector means ( 20 ) comprises a plurality of switches ( 21 ), said switches comprise: a common terminal ( 22 ), common to all the switches of the selector means under consideration, designed to be connected to a terminal of the corresponding electric power source ( 5 ); each a second terminal ( 23 ) connected to one of the electrical wires ( 10 ) of the main electrical network; c) in which the secondary distribution assembly ( 3 ) comprises for each electrical load ( 4 ) a secondary distribution subassembly selector means ( 30 ), which selector means ( 30 ) comprises a plurality of switches ( 31 ), which switches comprise: a common terminal ( 32 ), common to all the switches of the selector means under consideration, designed to be connected to the corresponding electrical load ( 4 ); each a second terminal connected to one of the electrical wires ( 10 ) of the main electrical network; so that each electrical load ( 4 ) is in time, by actions on the switches ( 31 ) of the secondary distribution subassembly selector means ( 30 ), linked to said electrical load, to be supplied by one or more electrical wires ( 10 ) of the main network and so that any wire ( 10 ) of the main network ( 1 ) can be individually isolated from said network by actions on the switches ( 21 , 31 ) of the selector means ( 20 , 30 ).
