WI switchgear units are completely metal-enclosed. The busbar

compartmentwhichaccommodatesxedpartsonlyissegregatedgas-tight

fromtheange-mountedswitchingunit.Theswitchingunitcomprisesthe

three-position switch with isolating and earthing functions and the vacuum

circuitbreaker; in case of double busbar systems, there are two three-

position switches with isolating and earthing functions and the vacuumcircuit-breaker.

The busbar compartment and the switching unit feature three-pole

enclosure. Single-pole enclosure is provided in the area of the toroidalcore

current transformers which are located in an easily accessible position

outside of the SF6atmosphere. The compact design results in a very clear

switchgear arrangement with low space requirement; it has the advantagethat a switching unit can be mounted or removed very quickly without the

busbar requiring isolation from the power supply.

The panels are equipped with a low-voltage cabinet for the required

measuring and protection relays or the terminal strips. The high

performance of the instrument transformers installed means that not onlyelectronic but also conventional protection relays can be deployed.

Thanks to its design, this panel series permits straightforward extension of

an existing switchgear on both sides, and extension from single to double

busbar models.

Gas-insulated double busbar switchgear WIBRated voltage up to 36 kV; rated peak withstand

current up to 100 kA; rated current up to 2500 A

WI Product description (contd.)

Components of the switching unit

The circuit-breaker in question is a vacuum circuit-breaker. The switching

unit has been equipped, for its isolating and earthing functions, with athree-position switch featuring the positions:

Earthing

The metal-enclosed WI series switchgear is equipped with a separate

earthing line running along the length of the switchgear.

Wiring

Wiringiseffectedwithexiblecables(HO7V-K)inthetechnicallyrequiredcross-sections.

Corrosion protection

If desired, the indoor panels WIA and WIB can be provided optionally with

enhanced corrosion protection. To ensure optimum switchgear protection,

the environmental installation conditions, such as wind-borne sand,

aggressivedust(tobedenedassaltdust,cokedust,cementdustetc.),

vermin(termites),increasedhumiditylevels,aggressiveatmosphere(typeofchemicalsandtheirconcentrationtobedened)mustbespecied.

Installation locations

The switchgear has been designed for installation in closed electrical

operating facilities.

Connection of cables and bars

The cables are connected by means of metal-enclosed connectors.

Switchgear units equipped with multiple connection tanks enable

connectionofuptove300mm2 cables or two 1250 mm2 cables perphase, depending on the insulation rating.

Alternatively, fully insulated busbar systems or SF6-insulated conductor

bars can be used.

Low voltage cabinet

The secondary devices for protection relay, control, measurement, billing

metering and other systems are installed in the low-voltage cabinet. Thelow-voltage cabinet is separated systematically from the primary part, is

shock-proof and arc-resistant. It is an independent, closed low-voltage

compartment with mechanical and electrical interfaces to the vertical

section(screw-fastenedplug-and-socketconnector).

The clear separation between the rack and the low-voltage cabinet is a

particularadvantageforthecompanyoperatingtheswitchgear.Retrotting

spare panels and conversion or replacement of complete low-voltage

cabinets(e.g.duetoprocesschanges)atalaterdateisalso

straightforward. The panel remains completely enclosed even if thelow-voltage cabinet is not attached.

Optional inspection ports can be integrated in the torsion-resistant door ofthe low-voltage cabinet, the door also being able to accommodate

measuring instruments, control elements and protection relays.

Current/voltage transformers

Current transformersThe current transformers are designed as toroidal-core transformers and

are put onto the cable outgoing feeder areas with single-pole enclosure.

The current transformers in line with the busbar consist of identical units.

There, they are slipped onto the busbar areas which also feature singlepole

enclosure. The capacity of the current transformers is designed in such a

way that supply of conventional protective devices is also possible.

Upto3transformers(3cores)canbeaccommodatedperphaseand

Threecurrenttransformers(3cores)perphasecanalsobeinstalledinline

with the busbar, in order to measure its currents.

A special current transformer arrangement is the bus coupler panel withinone panel width. In the double busbar top attachment tank, one core of

max.80mmheightwithanIDof135mmandanODof195mmcanbe

installed for each phase. The low voltage is led out via a max. 7-pole line

which is SF6proof.

on the busbar

A separate metering panel with a set of inductive voltage transformers isprovided to this effect. Taking account of the high priority of the busbar, a

disconnector enables isolation of the transformer section. Both

disconnector and transformer are located in separate compartments.

Thus, any damage which might occur in the vicinity of the transformer

does not affect the isolating area or the busbar.

The conventional solution for the inductive voltage transformer is a

InterlocksActuation of the three-position switch and the continuous mechanical

interlock between circuitbreaker and three-position switch are designed insuch a way that the operator can proceed as usual. This means separate,

completely interlocked actuation for the switching procedures Establishing

isolating distance and Earthing. For the earthing procedure, which is onlypossible with the three-position switch in isolated position, the circuit-breaker

switched off and the circuit-breaker energy-storing device pre-charged, the

circuitbreaker is connected positively after the contact blades have

beeninserted into the earthing contacts, and protected against immediate

mechanical or electrical switching OFF. Vice versa, on de-earthing, the

circuit-breakerisrstswitchedoffpositivelybeforetheisolatingdistancetothe earthing contacts established. The interlocks ensure that each

switching operation is always performed completely. Thus, once the

switching operation has commenced, the motion cannot be reversed, if

applicable, and the operating lever cannot be removed before it reaches its

end position.

The description only refers to the single busbar. In the case of double

busbars, some of the internal interlocking functions of the panel, as well as

all inter-panel interlocking functions are performed by electro-mechanical

interlocks(blockingcoil).

The following interlocking functions are provided:

Disconnector does not switch ON while the circuit-breaker or the earthing

switch are ON

None of the disconnectors switches OFF while the circuit-breaker or the

earthing switch are ON Circuit-breaker only switches ON with the disconnector in its end position

No earthing with disconnector engaged

No earthing with circuit-breaker ON No earthing without circuit-breaker being in ready-to-operate condition

Automatic connection of circuitbreaker during earthingAutomatic disconnection of circuit- breaker during de-earthing

The following has been ensured:

The operating crank cannot be removed from the disconnector or

earthing switch before it has reached its end positions completely

The circuit-breaker cannot be actuated while a switching operation is

being performed on the disconnector or earthing switch The circuit-breaker cannot be switched off with the three-position switch

in earthing position

All interlocks act partly mechanically and partly electrically

An operating crank can only be inserted on the disconnector or earthing

switch once the insertion opening has been released via a manualinterrogation system.

All interlocks also effective when the three-position switch is

motor-actuated.

WI Cable connections

Cable connections in outgoing feeder blockThe medium-voltage cables are connected to the switchgear panels via

metal-enclosed inner cone-type plug-in terminations. The panels areequipped with inner cone-type appliance couplers according to EN 50 181.

Themanufacturersspecicationsoftheregardingselectionandassembly

of the plug-in terminations must be adhered to. This does not only apply to

the selection of size, but also to all electrical rated data, in line with the

switchgears data.

It is essential that all appliance couplers which are not equipped withplug-in terminations are terminated correctly using voltage-proof and fully

shrouded insulating terminals/ dummy plugs.

To this effect, the inner cone-type cable plug-in terminations for attachment

to WI require capacitive decoupling. The coupling electrodes for the

capacitive voltage detection system are an integral part of the appliance

couplers installed in the switchgear panel.

WI Ecological considerations

A WI switchgearsatisestoahighdegreeecologicalrequirementsinviewof environmental protection thanks to

optimization of material and energy consumption during manufacture compliance with all ecological requirements during its service life theuseofrecyclablematerialsforefcientdisposalattheendofitsservice life.

Our design directives regarding environmentally compatible design specifythe use of materials which are easily recyclable and can be disassembled.The metals which make up approx. 90 % of the switchgear are easilyrecyclable. At the end of their service life, they are recycled 100 % in theform of homogenous materials.

Plastics can also be recycled. Thermosetting i.e. non-melting plasticscanbecomminutedandreusedasllersinotherplasticcomponents;thermoplastic - i.e. melting - materials can be recycled in the form ofhomogenous material. This means that the material is conserved, melteddown and used for the construction of new durable parts.

Toensureefcientandenvironmentallycompatibledisassemblyandassignment of materials by the responsible disposal experts, the

switchgearsplasticcomponentshavebeenidentiedaccordingly.Moreover, material and utilization data sheets are available to provide thecustomer with an overview about the materials used. Equally, the disposalcompany is provided with important information regarding the recycling process.

Thus, the materials used for our products can be reused 100 %.

This represents a major contribution towards saving primary energy andmaterial resources.

and so as to enable straightforward replacement of part components, e.g. ifnewcontrollershavebeendevelopedonthemarket(upgrading).

environmentalinuencesreducingtheservicelifeareshutout.Thespecialcharacteristics of the insulating gas also enable an overall size reduction byapprox. 50 percent versus switchgear designed without insulating gas withcomparable technical properties. This again saves a lot of material andenergy required for material production. The portion of insulating gas usedfor WI switchgear amounts to approx. 0.5 percent by weight. Once theswitchgears service life has elapsed, the gas is extracted completely viathedisposalvalveprovidedseriallyineachgas-lled,claddedcompartment, and then recycled. The gas suppliers have developed anefcientrecyclingconcepttothiseffect.

During normal operation, the gas need not be replenished during the entireservice life of the switchgear. The switchgear is a hermetically sealedpressuresystemacc.toIEC60694(IEC62271-1).

WI Shipping instructions

Transporting the switchgear unitWhen transporting the switchgear unit, it is important to ensure that the

transportunitsdonotsliportilt(ifnecessary,nailtransportpalletdowntotheloadingsurface).Reusetheoriginalpackagingtostorepartswhich

have been unpacked for inspection.

Packaging of the switchgear

If packed for truck transport, the switchgear unit is delivered on a pallet

withPEprotectivelm.

Forsea-worthytransport,theunitsarepackedinsealedaluminiumlm

with desiccant and in a closed case with tightly closed wooden base. In case of air transport, the switchgear unit is packed in a wooden crate

withclosedwoodenbaseandwithablisterIPElmasdustprotectionor

in a wooden case, also with closed wooden base.

Transport to the site of installationStore under conditions admissible for switchgear operation. Avoid

condensation.

During transport to the site of installation, remember that the main weight islocated in the top area of the switchgear top-heavy.

Transport using a forklift truck: Only transport the switchgear on a pallet.

Attention top-heavy!

Transport without pallet: The crane mounting harness must be hooked into

the jack rings of the switchgear.
