<p>HIGH VOLTAGE METALLIC SUBSTATION HAVING ONE AND A HALF CIRCUIT BREAKERS PER FEEDER The metallic substation is of the three-phase type with one and a half circuit breakers per feeder, and comprises two busbars (BO1, BO2) to which a plurality of single-phase cubicles (14R to 18T) with separate phases are connected. The circuit breakers (20R to 24T) of the cubicles are aligned longitudinally according to a direction parallel to the busbars (BO1, BO2) being housed in vertical enclosures, located at regular intervals along the busbars. The lower and upper transverse connections of the circuit breakers (20R to 24T) extend respectively in two planes parallel to the busbars (BO1, BO2). Applications : metallic high voltage electrical installations. Refer to figure 4.</p> |
