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

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
outgoing feeder. The transformers can also be exchanged subsequently.
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

WI Product description (contd.)
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 over- view 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.

Anotherimportantecologicalaspectisthelongevityofourproducts(min.30to40years),whichisanextremelylongservicelifecomparedtoothercapital goods. Furthermore, the switchgear units have been designed so asto require little maintenance which would in turn use up energy and material,
and so as to enable straightforward replacement of part components, e.g. ifnewcontrollershavebeendevelopedonthemarket(upgrading).
In our gas-insulated switchgear WI, the majority of the switchgear panelhasbeensealedhermeticallyinaninsulatinginertgas(sulphurhexauorideSF
6whichisneitherreactivenortoxic).Thus,all
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).
