General overviewMain characteristicsPE57608CBGS-2 range of switchgears has been officially approved by the main power supplyutilities as well as by the main industrial and infrastructure users. Nowadays, more than7,000 switchgears of the CBGS range have already been installed.This range of switchgears offers certain distinctive characteristics, such as thefollowing ones:b Low working pressure (0.4 relative bars)b Homogeneous architectureb High degree of partitioningb Optional gas exhaustion channel for single busbar version.Besides, the design of he CBGS-2 switchgears fully meets the basic requirementsof end users:b Investment optimizationb Service continuityb Operation safety.Investment optimizationThe switchgears of the CBGS-2 range are the best choice of investment due tothe following features:Optimization of the required space compared to other outdoor solutionsb The compact design, as well as the SF6 insulation of the switchgears, provideextremely reduced dimensions compared to traditional outdoor solutions.b An appropriate solution is thus provided for urban environments or reducedspaces.Simplified engineeringAs a result of the experience gathered in collaboration with Power Supply Utilities,Consultants and Contractors, there is a complete range of already developedsolutions which considerably simplify the engineering work.Integral management of networksFor those clients who wish to install a complete supervision system for theirswitchgears in order to improve their electrical supply, there is a full range ofprotection, control and monitoring elements suitable for CBGS-2 switchgears.Service continuityChoosing CBGS-2 switchgears provides users with the highest degree of availabilityof their MV units, thus ensuring the greatest reliability and quality when supplyingenergy to the clients of the Power Supply Utilities.Highly confirmed qualityb Proven experience in the design and manufacturing of SF6 insulated primarydistribution switchgears.b Use of 3D design techniques and other advanced tools.b Fully factory-tested equipments.Solid and safe designb CBGS-2 cubicles can neither be affected by moisture or dirt, nor by corrosive orpolluted operating environments, since all high voltage parts are contained insidethe SF6 tanks, which are made of stainless steel.b The hermetic nature of the stainless steel tanks ensures the protectionof the cubicles against external agents such as dirt, dust, insects, rodents, etc.High degree of maintenance and repairabilityb The operating mechanism of the circuit breaker is accessible from the outside ofthe stainless steel sealed tank.b The screened voltage transformers, can be plug-in type and independent fromthe stainless steel tank.b Possibility of elements replacement, such as three-phase bushings, gaskets,disconnectors, etc. without moving the affected cubicles or the adjacent ones.b Possibility of intermediate cubicles replacement without moving the adjoining ones.Extensions under voltageThe design of CBGS-2 switchgears, double busbar version, allows the extension ofa switchboard without cutting off service.Low maintenanceThere is practically no maintenance required for the operation of a CBGS-2switchboard and this is mainly focused on the operating mechanisms.<strong>DEGI04EN</strong>.indd5

Apparatus52 kV circuit breakerPE55037 PE57616The circuit breakerThe circuit breaker of CBGS-2 switchgears has separate poles, is “puffer” typeand uses SF6 gas as breaking and insulating medium.The cast resin enclosure of the circuit breaker fulfils the requirements of IEC 62271-100standard regarding sealed pressure systems.The relative pressure of SF6 filling is 0.48 Mpa (4.8 bar).In the very improbable event of a pressure falling underneath the established workingthreshold, 2 alarms, (at different levels) will be automatically released.Puffer type breaking system: operating principle(1) The fixed and mobile main contacts are initially closed.(2) PrecompressionWhen the fixed and mobile contacts begin to open, the piston slightly compressesthe SF6 gas inside the pressure chamber.(3) Arcing periodThe arc strikes between the arcing contacts while the piston continues its movement.A small quantity of SF6 gas is injected onto the arc through the insulating nozzle.For the breaking of low currents, the arc is cooled by forced convection.For high currents, however, thermal expansion causes the hot gases to move towardsthe colder parts of the pole unit.The distance between the two arcing contacts becomes sufficient for the current to bebroken when it reaches the zero point, due to the dielectric properties of SF6 gas.(4) Final sweepingThe moving parts finish their movement and the injection of cold gas continues untilthe contacts are completely open.Characteristics of the circuit breaker(1) (2)(3) (4)Rated voltage 50/60 Hz kV 52Power frequency withstand kV (rms) 95voltage insulation level(50 Hz–1 min)Lightning impulse withstand kV (peak) 250voltage insulation level(1.2/50 μs)Rated normal current A 2000Short circuit breaking current kA (rms) 25Short circuit making current kA (peak) 63Short time withstand current kA (rms) 25(3 s)Capacitor breaking current A 220for rated currentRated operating sequenceO-0.3 s-CO-3 min-COApproximate operating time ms OpeningBreakingClosing35-4335-5855-6514 <strong>DEGI04EN</strong>.indd
ApparatusCircuit breaker operatingmechanismPE57618Operating mechanismThe opening and closing speed of the circuit breaker contacts used for CBGS-2switchgears is independent of the operator’s action.This electrically operated mechanism, which is always motorized, can performremote control functions and implement fast re-closing cycles.In CBGS-2 type switchgears, all the operating mechanisms are arranged outsidethe SF6 tank.Furthermore, maintenance in this type of operating mechanisms is quite reduced,as they use self-lubricating components.The operating mechanism consists of:b A spring system that stores the necessary energy for the opening and closingoperations.b A manual spring charging system.b An electrical motorized spring charging device that automatically rechargesthe springs in less than 5 seconds after the main contacts of the circuit breakerhave closed.b Mechanical opening pushbutton with optional padlock on the front panel.b <strong>Electric</strong>al system including:v Closing coilv Anti-pumping relayv Double tripping coilv Undervoltage coil (optional).b Operation counter.b A spring charging indication contact.b An end of spring charging indication contact.b Mechanical indicator for open/closed position.b Mechanical indicator for spring charging position.b An optional key lock to interlock the circuit breaker in open position.Auxiliary contactsThe operating mechanism is equipped with a block of a maximum of 15 auxiliarycontacts. The number of available contacts depends on the composition of theoperating mechanism and the options chosen. In any case, at least 3 O/C contactsare available on the switchgear outgoing LV terminal block for the external signals.Auxiliary contacts characteristicsRated current10 ABreaking capacity Alternating current voltage 10 A with 220 Vac(power factor ≥ 0.3)Direct current voltage1.5 A with 110 or 220 Vdc(L/R ≤ 0.01 s)<strong>Electric</strong>al characteristics of the operating mechanismOptionsSpring charging Closing release Double voltage Undervoltage coilmotortripping coil52 kV 52 kV 52 kV 52 kVSupply voltage Direct current V 48-110-125 VdcConsumption Direct current W 500 70 140 (2 x 70) 100/10Possible combinations of auxiliariesand quantities=orororbbbbbbbbbbbb<strong>DEGI04EN</strong>.indd15
