Device for distributing energy between a plurality of electronic modules with possibility of shedding

Device for partitioning electrical energy between a plurality of electronic modules (M1, M2, . . . , Mn) disposed in an electronic rack (1), with possibility of several levels of load shedding, comprising an electrical supply line (13) attached on the one hand to at least one electrical energy distribution network (20) and on the other hand to the various electronic modules (M1, M2, . . . , Mn) by way of breaker relays (I1, I2, . . . , In) and means for managing the load sheddings (16) instigating the commands for opening and closing the breaker relays (I1, I2, . . . , In) as a function of load shedding control signals (D1, D2, D3) applied to the electrical energy partitioning device and corresponding to the desired level of load shedding, the said electrical energy partitioning device being characterized in that the means for managing the load sheddings (16) comprise:

• a network partitioning load shedding commands (21) with several parallel electrical conductors (210, 211, 212), equal in number to that of the desired levels of load shedding, each attached to a load shedding control input corresponding to a particular level of load shedding,
• diode-type switches (S1, S2, . . . , Sn) carrying out an “or”-type logic function, equal in number to that of the breaker relays (I1, I2, . . . , In), each having an output attached to the control input of a breaker relay (I1, I2 or In) and inputs equal in number to that of the levels of load shedding, and
• a tag strip (22) interposed between the inputs of the diode-type switches (S1, S2, . . . , Sn) and the parallel conductors (210, 211, 212) of the network partitioning load shedding commands (21), making it possible to establish, with the aid of straps (220), connections between the inputs of each diode-type switch (S1, S2, . . . , Sn) and the electrical conductors (210, 211, 212) of the network partitioning load shedding commands (21) as a function of the load shedding levels allocated to the electronic module or modules (M1, M2, . . . , Mn) supplied by way of the breaker relay (I1, I2, . . . , In) whose control input is driven by the relevant diode-type switch (S1, S2, Sn).
