Automated stations
With its modular concept and optionsincluding motorized switching devi-ces and remote control modules,FBX is especially well-suited for theincreasing automation of secondarydistribution networks.To enable communication withpower system control centres, FBXprovides various project stages withsolutions integrated in the switchge-ar. All versions - from remote-signal-ling only to remote control and re-transmission of additional signalsfrom the substation are possible.
For automated power system opera-tion, FBX can be managed from theremote control station by motor con-trol and electrically via the microremote control module.
Modern communication techniques,including modem solutions for tele-phone lines, radio or GSM can beincorporated.
Fields of application
The FBX ring main units are used innon-accessible or in walk-in stationsbelonging to the public power sup-ply companies, of industry, infra-structure and windpower stations.
Example of an extensible FBX-E switchgear:
Ring main panels and the tie breakers designed as switch disconnectors are loca-ted at the left-hand and right-hand ends of the switchgear. The six outgoing feederpanels T2 for the transformer outgoing feeders with vacuum circuit-breakers aresupplied via two air-insulated FBX-M metering panels for billing metering.

5FBX Straightforwardplanning
The FBX is a gas-insulated three-pole enclosed switchgear systemfor secondary distribution. SF6 gas isused as the insulating medium. Thegas-filled, clad compartments of FBXare insensitive to environmentalinfluences such as humidity, dust,dirt and vermin, and afford maximumoperator safety.
FBX-C switchgear is available as classical non-extensible ring mainunits, with 2 to 4 switching units.FBX-E is the extensible version,with 1 to 4 switching units, whichare arranged in a common gas-filled,clad compartment. The functionalunits of FBX-E can be arranged inany order, without gas handling, toform the required multi-panel switch-gear arrangement.
FBX-E in-line technology offers thefollowing advantages:> Very cost-effective solution for
secondary distribution applications.> Can be installed from the outside
through very small access ope-nings and hatches, e.g. for installa-tion in cellars or on upper floors, orinside windpower stations.
> FBX-E modules can be aligned inany order.
> Subsequent expansion is possibleon both sides of the switchgear.
> Installation at the construction sitewith no gas handling.
Both FBX-C (non-extensible) andFBX-E (extensible) versions can beequipped with- circuit-breakers (C),- switch fuse combinations (T1),- Transformer outgoing feeders with
vacuum circuit-breakers (T2) forhigh-capacity distribution transfor-mers or outgoing feeders up to 400/630A
- busbar risers (R)- busbar risers with earth switches
(RE), help provide a very cost-effective solution to the require-ments of secondary distributionnetwork engineering.
FBX-M air-insulated metering panelswith conventional currentand voltagetransformers for medium-voltage bil-ling metering complete this range ofproducts.
The clear overall design of the FBXswitchgear range ensures straight-forward, reliable operation. A con-tinuous zero-force interlockingconcept prevents operator errors.
The generous space in the cableconnection compartments allowsthe use of various cable connectionsystems for outer cone-type appli-ance couplers to EN 50181. Up to 2x3 cable Tee screw-typeplugs or 3 cable Tee screw-typeplugs plus 3 surge arresters peroutgoing feeder can be installedwithin the standard switchgearprofile.

Outgoing feeder cable withswitch disconnector,version C
The three-pole switching units arelocated in the gas-filled, clad com-partment. The power from the exter-nal drive mechanisms is transmitteddirectly to the switching devices.
The three-position switch features amake-break snap-action mechanismfor the switch disconnector functionand a separate snap-action makingmechanism for the earth switchfunction.
Transformer outgoing feederwith switch fuse combina-tion, version T1
Switch fuse combinations complywith IEC 62271-105. The combina-tion consists of a three-positionswitch disconnector, gas-proof loca-ting tubes for the HV HRC fuse linksand additional earth switches on thecable connection end to ensuremaximum operator safety.
To facilitate replacement of theHV HRC fuses, earthing is alwaysprovided upstream and downstreamof the fuses. The two earth switchesare mechanically coupled and areoperated via a single drive.
The switch disconnector is equippedwith a snap-action mechanism formaking operations, and a stored-energy mechanism for breaking ope-rations. The stored-energy mecha-nism is mechanically pre-charged toprepare for a breaking operation. Ifthe striker of an HV HRC fuse linkoperates, the switch disconnector isswitched-off mechanically on allthree poles. In addition, a breakingoperation triggered by the trippingof any of the HV HRC fuse linkstrikers is displayed mechanically onthe front operating panel. Breakingvia a magnetic trip is also possible.
The Earth ON function is achievedvia a separate drive with a snap-action making mechanism.

Transformer outgoing feederwith vacuum circuit-breaker,version T2
The transformer outgoing feeder witha vacuum circuit-breaker, version T2,can be used on applications wherethe load current is too high to use aswitch fuse combination.
A typical application is the protectionof distribution transformers andwindpower stations up toS =3 x 400 A x 20 kV =13.8 MVA,or 6000 kVA (for 20 kV) when usinga vacuum circuit breaker and a com-bination of three current transformersand a current transformer operatedprotection relay. Operation and trip-ping on faults does not require anadditional auxiliary supply. The vacu-um circuit-breaker, version T2, isalso a cost-effective solution for theselective transfer at the medium-vol-tage point between a regional opera-ting agency and a customersswitchgear.
The T2 transformer outgoing feederconsists of the three-pole switchingunits, a vacuum circuit-breaker loca-ted upstream of the three-positionswitch, and an integrated outgoingfeeder switch on the cable end. Thedisconnector is operated via thesnap-action make/break mechanism.The make-proof earth switch is ope-rated via a snap-action makingmechanism.
Currents is detected via threetoroidal-core current transformers.In the event of an external fault, thevacuum circuit-breaker is switchedoff via the current transformer actua-ted protection relay.
The drive functions of the vacuumcircuit-breaker outgoing feeder T2are identical in design to those ofthe switch fuse combination T1.The operating sequence when amotor-operated drive mechanism isprovided is: 0 - 3 min - CO.
The vacuum circuit-breaker outgoingfeeder has been designed withratings of 400 A and 630 A. It isdesigned to switch 1000 times therated normal current. 50 short-circuitbreaking operations are possible upto a maximum fault rating of 20 kA.
The vacuum circuit-breaker featuresa snap-action making mechanismand a stored-energy breakingmechanism.
The stored-energy mechanism ismechanically pre-charged to ensureit is always ready for a breaking ope-ration. Electrical breaking when trip-ped by a protection relay is effectedvia a dedicated transformer-operatedrelease. The toroidal-core currenttransformer, the three-phase trans-former-operated WIC1 protectionrelay1) and the magnetic trip forswitching off the vacuum circuit-breaker all have matching functions.
For further details regarding theWIC1-2P protection relay, pleaserefer to the separate documents forthis relay.

INTERLOCKING SYSTEM
In developing the FBX switchgear,operator safety and operating relia-bility were given top priority. A con-tinuous interlocking system preventsincorrect operation. Thus, it is onlypossible to insert operating leversfor the switching devices if theinstantaneous operating state sopermits. Access to the cable con-nection compartments and to thefuse links is only possible if theappropriate outgoing feeder isearthed.

Motor drive forswitch disconnector andvacuum circuit-breaker
The switch disconnector ON-OFFfunction in the outgoing cable fee-der, C, and in the switch fuse combi-nation, T1, can be fitted with a motordrive as an option. The vacuum cir-cuit-breaker in the transformer out-going feeder, T2, can also be desi-gned with motor-actuation onrequest. The nap-action make-break
mechanism (SFU) or the snap-actionmake and stored-energy breakmechanism (SF) are mechanicallycoupled directly to the motor drive.The motor drive is installed in thedrive recess outside of the gas-filled,clad compartment, behind the operator interface.
The standard opening for manualoperation of the actuator is closed ifthe switchgear features a motordrive. An operating handle is sup-plied for emergency manual openingof the actuator in the event of failureof the motor or the motor supply.
Auxiliary switch
All switching devices of the FBXswitchgear can be equipped addito-nally with multi-pole auxiliary swit-ches. 2- or 4-pole auxiliary switchesare available on the switch discon-
nectors, vacuum circuit-breakers anddisconnectors. The earthing swit-ches can be equipped with 2-poleauxiliary switches. The auxiliary swit-ches can be re-set subsequently asNC contacts, NO contacts or pulsecontacts via adjustable cams.
The three-pole HV HRC fuse carrierin the switch fuse combination T1can be equipped additionally witha two-pole push switch for electricalsignalling of fuse tripped.

IN-LINE ARRANGEMENTFBX-E
FBX-E offers highly flexible in-lineconfigurations of switchgear forsecondary distribution applications.Functional units comprising up to fourswitching units can be lined up in anyorder. In-line connection is possibleon both sides.
Local assembly and in-line connec-tion of FBX-E does not require gashandling.
In-line connection is a very straight-forward process due to- the F-link busbar couplers on the
medium-voltage end.Variations between adjacentpanels are compensated by sphe-rical fixed contacts and movablecouplers allowing adjustment in allaxial directions;
- very safe dielectric seals withpotential-controlled siliconedeflectors externally earthed andadjustable to fit. These are a press-fit on to the in-line assembly, using a specifiedforce. Potential-controlled blankingplugs, with a design based on thethe F-link silicon deflectors, arelocated at the switchgear ends.These blanking plugs are held inposition, at the press-fitting force,by a common metal cover:
- integrated guide pins for alignmentof adjacent panels in a definedposition;
- panel screw couplings with clearlyfixed stoppers for the distancesbetween adjacent panels;
- a wall clearance of at least 180 mmis required for replacement oralignment of one or more functional units.
In-line connection of FBX-E
Extensible design FBX-E: additional space required on either side > 180 mmrequired (as clearance to the building wall) for extension/s on the switchgearside/s.

VOLTAGE DETECTIONSYSTEM
A high-resistance (HR) voltagedetection system (not integrated) toIEC 61243-5 and EN 61243-5, isused to check zero voltage of theoutgoing feeders. The multi-wayconnectors for the voltage indicatorsare located in the secondary systemsrecess. The indicators supplied asstandard are VDS systems (Horst-mann).
Optionally, the IVIS integrated Vol-tage Detecting System with integra-ted indicator can be used to checkzero voltage. Logic flash arrow sym-bols on the indicators display if amains voltage within the definedresponse thresholds is present. TheIVIS system does not require theelectrical repeat tests for voltagedetection systems.
The IVIS system has been designedfor maximum operating reliability. Itdoes not require a supply from anexternal source. It features climate-proof encapsulated electronics andis maintenance-free, because of thepermanent monitoring of indicationthresholds.
Phase coincidence is established viaintegrated, hermetically shieldedmeasuring bushings using a phasemonitor.IVIS satisfies the requirements ofIEC 61243-5 and EN 61243-5 forintegrated voltage detection system.
Short-circuit indicator
As an option, the outgoing cablefeeders, C, can be equipped withshort-circuit indicators, types AlphaM or E, optional F or Gamma manu-factured by Dipl.-Ing. H. HorstmannGmbH. Other brands are availableon request.
The short-circuit indicators can beset as follows, depending on thetype concerned:
> Response values: 400 / 600 / 800 / 1000 A
> Manual reset> Automatic reset after 2 or 4 hours> Remote signalling contact> Earth-fault detection
The magnet yokes acting as sensorsfor the Horstmann short-circuit indi-cators are installed on the outercone-type cable bushings.Retrofitting of short-circuit indicatorunits is possible at any time.
GAS COMPARTMENTTECHNOLOGY
The switching units are installed ingas-filled tanks made of corrosionproof chromium-nickel steel. SF6 isused as the insulating and quen-ching medium. FBX is a sealed pres-sure system to IEC 60694.During the service life of the switch-gear, it is not necessary to replenishthe SF6 gas. The gas pressure isindicated via a pressure gauge.
In the event of excess pressure, thegas-filled, clad compartment dis-charges downwards via a pressurerelief device, to prevent any hotgases from venting directly on tothe cable end boxes.

HIGH-VOLTAGE FUSELINKS
The fuse links are located in insula-ting tubes in normal atmosphere. Thefuse locating tubes are integrated inthe hermetically sealed, gas-filled,clad compartment as required by thesystem, which offers the followingbenefits:> The electrical field is contained
within the SF6 atmosphere.> The grip end of the fuse is located
in the field intensity shadow.> The area within the gas-filled, clad
compartment is completely pro-tected.
> The grip end area is insensitive in particular, the closed grip end isnot used to ensure electric tight-ness (insulating arrangement).
Option available: water-proofdesign of the fuse locating tubesand grip ends.
Fuse tripping
The stored-energy mechanism andthe tripping linkage ensure that allthree conductors of the switch fusecombination are switched off whentripped by the fuse striker. If thestriker of only one HV HRC fuselink operates, all-pole breaking iseffected mechanically.
Replacement of fuses
The interrogation interlock ensuresmaximum operator safety on fusereplacement. The fuse cover canonly be opened if correct earthinghas been carried out. Conversely,the earthing can only be reset afterthe fuse cover has been closed andlocked.
Two make-proof earth switches(upstream and downstream of thefuse links) enable the fuses to bereplaced without the use of auxiliaryequipment. Both earth switches aremake-proof and are switched via acommon snap-action making mecha-nism.

SELECTION OF HV HRCFUSE LINKS
1. HV HRC fuse links
This project document gives therecommendations of the switchgearmanufacturer, as required by theapplicable Standards. The specifieddata enables the user to choosesuitable HV HRC fuse links.
Types of HV HRC fuse links
To protect distribution transformers,we recommend the use of HV HRCbackup fuses with integrated thermalcut-outs for gas-insulated FBXswitchgear, according to the selec-tion tables on page 33.
The thermal cut-out of the HV HRCfuses will operate:> in the event of overload currents,> in the event of fuse link damage by
previous transients,causing a shut-off by the switch-dis-connector.This prevents thermal overloading ofthe fuse locating tubes.
Ordering data
The following data must be specifiedin the Purchase Order:> Transformer rated power> Transformer service voltage> Rated current of the selected
HV HRC fuses.
Technical data
The technical data on page 33 hasbeen prepared for normal applicationof switchgear units and takesaccount of all appropriate standards.
These standards are:> Protection of distribution transfor-
mers according to IEC 60787, Transformer connection symbolDy5
> Fuse links acc. to IEC 60282-1> Specifications of IEC 62271-105> Max. ambient temperature for
switchgear: 40 oC to IEC 60694,and also for switchgear within thehousing of a packaged substation,to IEC 61330.
No transformer operation duringoverload.
LV HRC fuse links gTr to VDE 0636,Part 2011, can be selected as analternative to the HV HRC fuse links.
The HV HRC fuse links can carry1.3 times the transformer rated cur-rent for a minimum of 10 hours.Shut-off is effected at 1.5 times thetransformer rated current within twohours.
High ambient temperature
The selection tables are also valid fora max. ambient temperature of 50 oC,e.g. for the switchgear within thehousing of a packaged substationaccording to IEC 61330,DIN EN 61330, for very hotclimate conditions.
Temperature-rise limits
The selection tables take intoaccount the temperature-rise limitswithin the switchgear enclosure.
2. HV HRC fuse links Selection data
Back-up fuse links
Fuse links must correspond with:> IEC Publication 60282-1 with
dimensions according to datasheet I (design I)
> striker type "medium" with maxi-mum initial tripping force of 80 N.

When using back-up fuses withoutintegrated, temperature-limiting stri-ker pin release, the following require-ments must be met:> In the event of overload currents,
shut-off must be effected by theLV HRC fuse links, as indicated onpage 12.
> In case of switchgear installed inan exposed location, where fuselinks may be subject to damagecaused by transient events (forexample lightning strikes), itshould be ensured that all fuselinks are changed at appropriatemaintenance intervals.
If these requirements are not satis-fied, only HV HRC backup fuselinks with integrated striker trippingand cut-out feature must be used inthe gas-insulated FBX switchgearto protect the switchgear againstthermal overload.
The following types of HV HRC fuselinks with integrated striker trippingand thermal cut-out feature areacceptable:
Length of fuse links
FBX switchgear is designed toaccommodate fuselink lengths of"D" or "e" as follows:
General-purpose fuses
General-purpose fuses are recom-mended for the exceptional case inwhich the switch disconnector is tobe equipped with an SFU ON/OFFsnap-action drive (instead of an SFstored energy mechanism), when all-pole fuse tripping is not possible.

Ecological considerations>>The switchgear satisfies to a highdegree the ecological requirementsin respect of environmental protec-tion thanks to> optimization of material and energy
consumption during manufacture> compliance with all ecological
requirements during its service life> the use of recyclable materials for
efficient disposal at the end of itsservice life.
Our design directive regarding en-vironmentally compatible designspecifies the use of materials whichcan be dismantled and are easilyrecyclable. The metals which formapproximately 90 % of the switch-gear are easily recyclable. They canbe 100 % recycled as new metalcomponents at the end of their service life.
Plastics can also be recycled. Thethermosetting plastics can be frag-mented and re-used as fillers inother plastic components; the ther-moplastic materials can be recycledin new plastic components. Thismeans that the material is recovered,processed and re-used in the manu-facture of new parts.
To ensure efficient and environmen-tally friendly dismantling and sortingof materials by responsible disposalexperts, all plastic components areidentified accordingly. Moreover,material and utilization data sheetsare available to provide the customerwith an overview about the materialsused, and the disposal company withimportant information regarding therecycling process.
Thus, the materials used for our pro-ducts can be 100 % recycled.
This provides a vital contribution tosavings in global primary energy andmaterial resources.
All materials were selected anddeveloped so that, for example,switchgear affected by a fire in abuilding would have a minimal effecton the fire load (heat developmentand pollutants in the emissions).
Another important ecological aspectis the longevity of our products(approx. 30 years), which is an ex-tremely long service life compared to other capital goods. Also, theFBX switchgear units have beendesigned to require little mainten-ance, giving further energy andmaterial savings, and to enablestraightforward replacement of com-ponent parts, e.g. if new controllershave been developed (upgrading).
The high-voltage conducting parts ofour gas-insulated switchgear unitsare hermetically sealed in an insula-ting inert gas (sulphur hexafluorideSF6 which is neither reactive nortoxic). Thus, all environmental influ-ences which could reduce the ser-vice life are kept outside. The parti-cular characteristic of the insulatinggas also enables the overall size tobe decreased by approximately 30 %compared to switchgear withoutinsulating gas designed with equiva-lent technical characteristics. Thisagain saves on material and saveson the energy required to producethe material. The amount of insulating gas used inGMA is approx. 0.5 % of the totalweight of the switchgear. Once theswitchgears service life has ended,the gas can be completely extractedvia the disposal valve provided ineach gas-filled compartment, andthen recycled. To this end, the gassuppliers have developed an efficientrecycling method.
In normal operation, the gas neednever be replenished during the entire service life. The switchgearhas been designed as a hermeticallysealed pressure system according to IEC 60694 and EN 60694.
