1 GENERAL CHARACTERISTICS

GeneralThe PowerCube modules allow construction of metal-cladmedium voltage air-insulated switchgear with the same ratedcurrents as those of the enclosure.

In fact, the rated currents of the enclosures refer to versionstested in ABB UniSafe type switchgear.

In particular, the 4000 A PB3 enclosure means it is possible toconstruct switchgear with the same rated current as long as asuitable fan is applied in the back of the switchgear (for furtherinformation, please ask ABB).

The PB type PowerCubes are available in two different versions:PB/M and PB/E.

PB/M: complete module including the cable access compart-ment which can also be prepared to house the withdrawable VTcompartment.

PB/E: compounded enclosure with the cable access compart-ment and therefore without the possibility of housing the with-drawable VT compartment, but, thanks to its smaller overalldimensions, more flexible and suited to developing double-levelswitchgear.

The PowerCube modules are pre-assembled and factory-testedand comply with IEC 62271-200, CEI 17-1, IEC 60694 and CEI17-6 Standards.

PowerCube type PB/M Module.

The following apparatus can be installed in thePowerCube modules:• VD4, VM1, eVM1 and Vmax series vacuum

circuit-breakers• HD4 series gas circuit-breakers• V-Contact series vacuum contactors• service trucks.All the operations of the apparatus are carried outfrom the front of the module/enclosure.

Degrees of protection The degrees of protection of the PowerCubemodules comply with the IEC 60529 Standards.

The following standard degrees of protection areguaranteed on the front:

– external housing: IP4X– inside the units: IP2X.

HD4 series gas circuit-breaker.

VD4 series vacuum circuit-breaker.

Circuit-breakersThe PowerCube units can be fitted with HD4 series SF6withdrawable and VD4, VM1, eVM1 and eVmax series vacuumcircuit-breakers.The circuit-breakers are fitted with a truck which allows theirracking-in and out of the switchgear with the door closed.Both types have a compact and light structure which ensuresgreat sturdiness and excellent mechanical reliability.The operating mechanism and poles are fixed to the metalstructure which also acts as a support for the moving contactactuation kinematics.

HD4 series SF6 Circuit-breakersThe HD4 series of medium voltage circuit-breakers use sulphurhexafluoride gas (SF6) to extinguish the electric arc and as theinsulating medium.The breaking principle of HD4 circuit-breakers is based oncompression and self-blast techniques to obtain top perform-ances at all service current values, with gradual arc extinction,no restriking, operating overvoltages or chopped currents.These characteristics guarantee long electrical life for thecircuit-breaker and limited dynamic, dielectric and thermalstresses on the installation.The circuit-breaker poles, which make up the interruption part,are sealed for life pressure systems (IEC 62271-100 and CEI17.1 Standards) and are maintenance-free.The stored energy mechanical operating mechanism has freetrip and allows opening and closing operations independent ofthe operator’s actions.

VD4, VM1 and eVM1 series vacuum circuit-breakersThe VD4, VM1 and eVM1 circuit-breakers use vacuum as theinterruption and insulating medium.Thanks to the advanced techniques used for their construction,the vacuum circuit-breakers ensure high performances underall service conditions.The vacuum interrupters are embedded in the poles made ofepoxy resin. This construction means the interrupters areunaffected by shocks, humidity and environmental pollution.The circuit-breaker poles, making up the interruption part, aresealed for life pressure systems (IEC 62271-100 and CEI 17.1Standards) and are maintenance-free.The VD4 circuit-breakers use a mechanical type of operatingmechanism, the VM1 and eVM1 circuit-breakers use anoperating mechanism with a magnetic actuator.They are both stored energy operating mechanisms with freetrip and allow opening and closing operations independent ofthe operator’s actions.The eVM1 circuit-breakers are also fitted with an integratedmeasurement and protection system which can be configuredby means of a personal computer, directly by the customerusing some simple software.

V-Contact seriesvacuum contactors VSC/P and V/P.

Vmax/W series vacuum circuit-breakersVmax circuit-breakers are made up of an insulating monoblocin which three vacuum interrupters are fixed. The monoblocand the operating mechanism are fixed to a frame.The vacuum interrupters house the contacts and make up theinterruption chambers of the circuit-breaker.Vmax circuit-breakers use a mechanical stored energy operat-ing mechanism with free trip which allows opening and closingoperations independent of the operator’s actions. The mechani-cal operating mechanism is of simple concept and use and canbe personalised with a wide range of easily and rapidly in-stalled accessories.This simplicity characterised the apparatus for its reliability,duration and limited maintenance.Vmax circuit-breakers are used in power distribution for controland protection of cables, overhead lines, transformer anddistribution substations, motors, transformers, generators andcapacitor banks.The circuit-breaker vacuum interrupters, which make up theinterruption part, are sealed for life pressure systems (IEC62271-100 and CEI 17.1 Standards) and are maintenance-free.

Vmax/W series vacuum circuit-breaker.

V-Contact V/P and V-Contact VSC/P series vacuum contactorsUse of V-Contact series withdrawable contactors is foreseen in the PB1 PowerCube units up to 12 kV.The contactors are suitable for controlling alternating current users which require a high number ofoperations.They consist of a resin monobloc where the vacuum interrupters, moving equipment, operating mecha-nism, multivoltage feeder and auxiliary accessories are housed.The monobloc is also the support for installation of the fuses.Fuses according to DIN or BS Standards of different dimensions can be used thanks to special adapters.The type of fuseholder (BS or DIN) must be specified when ordering.Contactor closing is prevented when even a single fuse is missing. Opening is automatic when one of thethree fuses blows.They are of compact and sturdy construction and guarantee very long electrical and mechanical life.

2 MAIN COMPONENTS

Service trucksThe PowerCube range is equipped with all theservice trucks needed to complete the switchgearand required for service operations and duringmaintenance work.The trucks are divided into four different types:• earthing without making capacity.• earthing with making capacity.• cable testing.• isolation.

Note: the earthing trucks with making and isolationcapacity are available derived from the HD4 series only.

• Earthing truck without making capacity “E”These trucks carry out the same function as theearthing switches without making capacity.They therefore have no capacity to earth livecircuits in fault conditions.They are used to ensure an additional fixed earth,as is required by the installation service andmaintenance procedures, as a further guaranteefor personnel.The use of these trucks foresees removal of theswitching apparatus from the switchgear (circuit-breaker or contactor) and its replacement with thetruck. The units preset for use of the earthingtrucks can be provided with a key lock which,when activated, prevents their racking-in.This truck is available in two versions:• earthing of the main busbar system (E/U series).• earthing of the power cables (E/L series).During the racking-in phase, the main busbarearthing truck only actuates the top shutter andearths the contacts connected to the top branchconnections (and therefore to the main busbarsystem) by means of the switchgear structure.

During the racking-in phase, the power cableearthing truck only actuates the bottom shutterand earths the contacts connected to the bottombranch connections (and therefore to the powercables) by means of the switchgear structure.These trucks can be used in incoming or outgoingunits or in dedicated units.They can also be used in bus-tie units. In thiscase, they earth one of the two sides of the mainbusbar system.

• Earthing truck with making capacity “EM”These trucks carry out the same function as theearthing switches with making capacity.They consist of circuit-breakers only fitted withtop (main busbar earthing) or bottom (power cableearthing) terminals. The contacts without termi-nals are short-circuited by means of a copper barand connected to earth by means of the appara-tus truck.

They keep all the characteristics of the circuit-breakers, such as full making capacity on livecircuits under fault conditions.They allow closing operations to be carried outrapidly with remote electric control.The use of these trucks foresees removal of theswitching apparatus from the switchgear (circuit-breaker or contactor) and its replacement with thetruck. The units preset for use of the earthingtrucks can be provided with a key lock which,when activated, prevents their racking-in.This truck is available in two versions:• main busbar system earthing (EM/U series)• power cable earthing (EM/L series).During the racking-in phase, the main busbarearthing truck only lifts the top shutter andprepares the contacts connected to the topbranch connections (and therefore to the mainbusbar system) to close to earth by means of acontrol.During the racking-in phase, the power cableearthing truck only lifts the bottom shutter andprepares the contacts connected to the bottombranch connections (and therefore to the powercables) to close to earth by means of a control.These trucks can be used in incoming or outgoingunits or in dedicated units.They can also be used in bus-tie units. In thiscase, they earth one of the two sides of the mainbusbar system.

Isolating truck.

Connection is made extremely safe by using thepoles of the circuit-breakers to insulate theconnection busbars from the external environ-ment.In the incoming/outgoing units, the isolating truckconnects the main busbar system to the powercables, whereas in the bus-tie units, it connectsthe two sides of the busbar system.This truck has its application in switchgear formaking incoming/outgoing units without a circuit-breaker in radial networks, for making cableconnections between two switchgear placed infront of each other, in making interconnectionunits and in creating bus-tie-riser units withdouble isolation (in this case, both units are madeup of bus-ties, the former fitted with acircuit-breaker and the latter with an isolatingtruck).The units preset for using isolating trucks arefitted with a key lock which, when activated,prevents their being racked-in.

• Power cable testing truck “T”These trucks allow the insulation tests on thepower cables to be carried out without accessingthe feeder compartment or disconnecting thecables from the switchgear. The use of thesetrucks foresees removal of the switching appara-tus from the switchgear (circuit-breaker or contac-tor) and its replacement with the truck.During the racking-in phase, the truck only liftsthe bottom shutter and, by means of the connec-tors it is fitted with, allows connection of the testapparatus cables by means of a special insulatingrod (testing apparatus and insulating rod must beprovided by the customer).This truck can only be used in incoming/outgoingunits.

• Isolating truck “S”The isolating truck allows the top switchgearcontacts to be connected directly to the bottomones.

2 MAIN COMPONENTS

Earthing switchesThe PB type PowerCube units canbe fitted with an earthing switch. Theearthing switch is fitted withmaking capacity on short-circuit.The opening and closing operationscan be locked, on request, bymeans of key locks.Earthing switch control is carried outfrom the front of the module withmanual operation suitably inter-locked with the position of thecircuit-breaker.For availability of the accessories,please see the table on page 21.

Monoblocs and shuttersThe monoblocs consist of insulating bushings containing thepower connections - top and bottom - of the circuit-breakercompartment, towards the feeder and busbar compartmentsrespectively.The shutters are of the metal type and are activated automati-cally during movement of the circuit-breaker from the test/isolated position to the connected position and vice versa.They can be fitted with a fail-safe safety device (optional) toprevent their manual opening with the circuit-breaker removed.Each shutter can be locked by means of two independentpadlocks (optional).

PR512 switchgear protection deviceWith regard to the functionality of protections 50/51/50N/51N, the PR512 are self-supplied typereleases. To guarantee operation of the ammeterand of the dialogue function, an auxiliary powersupply must also be provided.They are available in the following versions:– PR512/P. Protection against overload (51) and

instantaneous or delayed short-circuit (50).– PR512/P. Protection against overload (51),

instantaneous or delayed short-circuit (50),earth fault (51N) and instantaneous or delayedearth fault (50N).

– PR512/PD. Protection against overload (51),instantaneous or delayed short-circuit (50),earth fault (51N) and instantaneous or delayedearth fault (50N). Dialogue function to beconnected to the electrical installation manage-ment system.

For the characteristics of the current transformersto be combined with the PR512, please refer totechnical catalogue 1VCP000055.

Voltage transformersThe voltage transformers are of the type insulatedin resin and are used to supply measuring andprotection devices.The are available for fixed assembly or for instal-lation on withdrawable trucks.They comply with the IEC 60044-2 Standards.Their dimensions are usually according to the DIN42600 Standard. The transformers installed onwithdrawable trucks are, on the other hand, of thededicated type.These transformers can have one or two poles,with performances and precision classes suitablefor the functional requirements of the instrumentsconnected to them.When they are installed on withdrawable trucks,they are fitted with medium voltage protectionfuses.Replacement of the fuses can be carried out withthe switchgear in service.

Current transformersThe current transformers are of the type insulatedin resin and are used to supply measuring andprotection devices. These transformers can eitherhave a wound core or a through bar with one ormore cores, with performance and precisionclasses suited to the installation requirements.They comply with IEC 60044-1 Standards.

For completion of the switchgear, ABB can also offer the components indicated below.For further details, please consult us.


Their dimensions are usually according to the DIN42600 Standard.The current transformers can also be fitted with acapacitive socket for connection to the voltagesignalling lamps.

Measurement sensors (for applicationwith REF542plus electronic or similarprotection units)The introduction of digital technologies intoelectrical measuring and protection instrumentshas considerably modified the performancesrequired of transformers.The analog input levels of the instruments havebeen notably reduced when compared with thoseof traditional systems.For this reason, ABB has introduced a new rangeof sensors which best covers the characteristicsof the new generations of instruments.The switchgear can be equipped with ABBKEVCD Block Type sensors up to 24 kV.The current sensors comply with the IEC 60044-8(CDV) Standards, whereas the voltage sensorscomply with the IEC 60044-7 Standards.The dimensions are in accordance with the DIN42600 Narrow Type standard.Both the current and voltage sensors or just thecurrent sensors can be integrated simultaneouslyin the same resin body. The voltage divider forconnection to the voltage signalling lamps is alsoinserted.The measurement sensors and the multi-purposeABB units have Cl. 1 class of precision.

• Current sensorThe current sensor consists of a Rogowski coilwithout the ferromagnetic core, so it is not af-fected by saturation phenomena.When a coil is formed by a uniform winding over aclosed non-magnetic core of constant cross-section, the induced voltage in the secondarycircuit is directly proportional to the variation inthe let-through current. To obtain a signal propor-tional to the current given, this voltage must beintegrated. The multi-purpose devices carry outthis function and use the signal obtained both forthe measurements and for the protections.

31

ABB KEVCD type combined voltage-current sensors.

Main characteristics of the current sensors

– Linear response over the whole measurement range;– no saturation phenomenon;– no hysterisis phenomenon;– a single instrument for protections and measurements;– high class of precision;– high degree of immunity to electromagnetic inter-

ferences;– the output signal is a voltage (150 mV) proportional

to the variation in the current time. Measurement ofthe current is obtained by integrating the signal;

– just two coils cover the range of rated currents from0 to 3200 A;

– the winding can remain open even with the switch-gear in service.

• Voltage sensor

The voltage sensor consists of a resistive dividerthrough which the signal is taken up. This sensor,too, is the of the unsaturable and linear type overthe whole measurement range.The output signal is a voltage directly proportionalto the primary voltage. The resistive elementconsists of a bar made of ceramic material.The voltages sensors are used for taking measure-ments and for supplying the protections with powersimultaneously.

Main characteristics of the voltage sensors– Linear response over the whole measurement range;– no saturation phenomenon;– no ferroresonance phenomenon;– a single instrument for protections and measure-

ments;– high class of precision;– high degree of immunity to electromagnetic

interferences;– the output signal is a voltage directly proportion-

al to the primary voltage;– the division ratio is 10000/1;– a single divider covers the range from 0 to 24 kV

rated voltage.
