PRODUCT LEAFLET CELL TYPE CDE 12 / 13 For medium voltage network 3200 V - 5500 V - 6600 V Cell with three outgoing feeder contactor Cell with two compartments with one outgoing feeder and one auxiliary transformer compartment

CELLS CDE 12/13 CDE12 : single phase network - CDE13 : three phase network APPLICATION FIELD AUGIER’s cells are specially designed to supply large MV networks. The control and protection units can operate more than 2000 times per year . The AUGIER equipments allow : - A very important rate of operation. - A good selectivity of tripping between the various protection devices of the network. - Maximum over current protection, even against faults far away from the cell. - Earth protection against ground leakage. In order to increase the installation reliability, AUGIER has designed a cell...

ELECTRICAL CHARACTERISTICS These characteristics are for operating temperatures of between 0°C and +55°C and for an altitude of less than 1000 meters. : 6,6 kV : 50 Hz : 20 kV - 50 Hz - 1 minute : 300 A : 3200 A - 1 second : 8300 A peak Switchboard with 3 cubicles Service voltage Normal frequency Dielectric strength Nominal current Thermal rating Electrodynamic rating Switchboard with 2 cubicles LOCKING DEVICES The locking devices are realised by locks, they are functional and adapted to the configuration of your switchboard, in particular, they prevent : - the closing of the earthing...

OUTGOING FEEDER CONTACTOR : D D FUNCTION Located upstream of the outgoing network, the outgoing feeder contactor allows : - supply of outgoing feeder thanks to its electrical endurance of 300 000 operations. - outgoing protection by a fuse linked to a homopolar and overcurrent protection device. - isolating, earthing and shortcircuiting of outgoing cables. DESIGN Each compartment contactor is equiped with : . A set of busbars, rating 300A, linking the compartment together. . The connection bars of dry type outgoing cables. . An earthing switch. . One current transformer per phase and one...

OPTIONS ALLOWING THE REMOTE CONTROL : . Serial link communication RS 232 - RS 485. . MV live voltage information brought back on the door terminals. . Analogical information 4-20 mA brought back on the door terminals. . Position of the earthing switch. OTHER OPTIONS : . CDTS 3000 software : Help to the setting of parameter for the outgoing feeder, storage of the adjusted parameters, updating of the software for the outgoing feeder, help to the repairing. OPERATING PRINCIPLE OF THE REMOTE CONTROL SOFTWARE All the parameters and adjustments are displayed on an alphanumerical interface...

FUNCTION Used to obtain complete isolation downstream of main transformer (CA). The design is identical to a «feeder» compartment. DESIGN Each compartment contactor is equipped with : . A set of vertical bus bars, rated 300 A, (2) or (3) phase. . An Earthing switch. . A Lateral right cable channel for incoming MV cable. . A Bar terminals for incoming cable, to be dry type without cable end boxes. . Standard locks. . a vacuum contactor, rating 400A, supply 230V. Cell two compartments with one raising block, one incoming contactor and one feeder contactor. On the door : low voltage control...

CC FUNCTION This compartment is used to link together two half bus bars each supplied by an incoming transformer. D DESIGN Characteristics and specification identical to the «incoming contactor » compartment. It is not designed to be equipped with an earthing switch. Example of composition of cells FUNCTION Provides power supply of substation auxiliaries. DESIGN This compartment is equipped with : - single-phase transformer, dry type, power rating 3 or 5 kVA, ratio 3200 or 5500/230 V - one or two HRC cut out fuses to protect the primary winding of above transformer against short circuits....
