TECHNICAL DESCRIPTION

WI panels are suitable for configu-

ring single or double busbar

switchgear in conjunction with

indoor installation.

WI switchgear units are completely

metal-enclosed. The busbar com-

partment which accommodates

fixed parts only is segregated

gas-tight from the flange-mounted

switching unit. The switching unit

comprises the three-position

switch with isolating and earthing

functions and the vacuum circuit-

breaker; in case of double busbar

systems, there are two three-posi-

tion switches with isolating and

earthing functions and the vacuum

circuit-breaker.

The busbar compartment and the

switching unit feature three-pole

enclosure. Single-pole enclosure is

provided in the area of the toroidal-

core current transformers which

are located in an easily accessible

position outside of the SF6 atmo-

sphere. The compact design

results in a very clear switchgear

arrangement with low space requi-

rement; it has the advantage that 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 requir-

ed measuring and protection relays

or the terminal strips. The high per-

formance of the instrument trans-

formers installed means that not

only electronic but also conventio-

nal 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.

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 func-

tions, with a three-position switch

featuring the positions:

Disconnector ON (CLOSE)

Disconnector earthing

switch OFF (TRIP)

Earthing switch ON (CLOSE)

EarthingThe metal-enclosed WI series

switchgear is equipped with a

separate earthing line running

along the length of the switchgear.

WiringWiring is effected with flexible

cables (HO7V-K) in the technically

required cross-sections.

Corrosion ProtectionIf desired, the indoor panels WIA

and WIB can be provided optional-

ly with enhanced corrosion protec-

tion. To ensure optimum switch-

gear protection, the environmental

installation conditions, such as

wind-borne sand, aggressive dust

(to be defined as salt dust, coke

dust, cement dust etc.), vermin

(termites), increased humidity

levels, aggressive atmosphere

(type of chemicals and their con-

centration to be defined) must be

specified.

Installation locationsThe switchgear has been designed

for installation in closed electrical

operating facilities.

Connection of cables andbars The cables are connected by

means of metal-enclosed connec-

tors. Switchgear units equipped

with multiple connection tanks

enable connection of up to five

300 mm2 cables or two 1250 mm2

cables per phase, depending on

the insulation rating.

Alternatively, fully insulated busbar

systems or SF6-insulated conduc-

tor bars can be used.

Low voltage cabinetThe secondary devices for protec-

tion relay, control, measurement,

billing metering and other systems

are installed in the low-voltage

cabinet. The low-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-fastened plug-and-socket

connector).

The clear separation between the

rack and the low-voltage cabinet is

a particular advantage for the com-

pany operating the switchgear.

Retrofitting spare panels and con-

version or replacement of complete

low-voltage cabinets (e.g. due to

process changes) at a later date is

also straightforward. The panel

remains completely enclosed even

if the low-voltage cabinet is not

attached.

Optional inspection ports can be

integrated in the torsion-resistant

door of the low-voltage cabinet,

the door also being able to accom-

modate measuring instruments,

control elements and protection

relays.

CURRENT/VOLTAGE

TRANSFORMERS

Current transformersThe current transformers are de-

signed as toroidal-core transfor-

mers and are put onto the cable

outgoing feeder areas with single-

pole enclosure. The current trans-

formers in line with the busbar

consist of identical units. There,

they are slipped onto the busbar

areas which also feature single-

pole enclosure. The capacity of the

current transformers is designed in

such a way that supply of conven-

tional protective devices is also

possible.

Up to 3 transformers (3 cores) can

be accommodated per phase and

outgoing feeder. The transformers

can also be exchanged subse-

quently. Three current transformers

(3 cores) per phase can also be

installed in line with the busbar, in

order to measure its currents.

A special current transformer

arrangement is the "bus coupler

panel within one panel width". In

the double busbar top attachment

tank, one core of max. 80 mm

height with an ID of ≤ 135 mm

and an OD of ≥ 195 mm can be

installed for each phase. The low

voltage is led out via a max. 7-pole

line which is SF6 proof.

VOLTAGE TRANSFORMER

The conventional solution for the

inductive voltage transformer is

a separate single-phase metal-

enclosed module which can be

connected via cable connectors

almost anywhere in the busbar

area and on the outgoing feeder

cable, and thus arranged in practi-

cally any location as required.

- in the outgoing feeder area

Another design comprises

metal-enclosed inductive voltage

transformers directly flange-

mounted to the outgoing feeder

block, with the isolating / earth-

ing device mounted upstream.

An externally operated isolating

feature prevents the voltage

transformer from being endan-

gered/put at risk during DC tests

on the cable.

– on the busbar

A separate metering panel with a

set of inductive voltage transfor-

mers is provided to this effect.

Taking account of the high priori-

ty of the busbar, a disconnector

enables isolation of the transfor-

mer 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.

16

INTERLOCKS

Actuation of the three-position

switch and the continuous mecha-

nical interlock between circuit-

breaker and three-position switch

are designed in such a way that

the operator can proceed as usual.

This means separate, completely

interlocked actuation for the switch-

ing procedures ”Establishing isola-

ting distance” and “Earthing”. For

the earthing procedure, which is

only possible with the three-posi-

tion switch in isolated position, the

circuit-breaker switched off and

the circuit-breaker energy-storing

device pre-charged, the circuit-

breaker is connected positively

after the contact blades have been

inserted into the earthing contacts,

and protected against immediate

mechanical or electrical switching

OFF. Vice versa, on de-earthing,

the circuit-breaker is first switched

off positively before the isolating

distance to the earthing contacts

established. The interlocks ensure

that each switching operation is

always performed completely.

Thus, once the switching operation

has commenced, the motion can-

not 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 dou-

ble busbars, some of the internal

interlocking functions of the panel,

as well as all inter-panel interlock-

ing functions are performed by

electro-mechanical interlocks

(blocking coil).

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 swit-

ches OFF while the circuit-brea-

ker 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-brea-

ker being in ready-to-operate

condition

- Automatic connection of circuit-

breaker during earthing

- Automatic disconnection of cir-

cuit-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 com-

pletely

- The circuit-breaker cannot be

actuated while a switching ope-

ration is being performed on the

disconnector or earthing switch

- The circuit-breaker cannot be

switched off with the three-posi-

tion switch in earthing position

- All interlocks act partly mechani-

cally and partly electrically

- An operating crank can only be

inserted on the disconnector or

earthing switch once the inser-

tion opening has been released

via a manual interrogation

system.

- All interlocks also effective when

the three-position switch is

motor-actuated.

CABLE CONNECTIONS IN

OUTGOING FEEDER

BLOCK

The medium-voltage cables are

connected to the switchgear

panels via metal-enclosed inner

cone-type plug-in terminations.

The panels are equipped with inner

cone-type appliance couplers

according to EN 50 181.

The manufacturer’s specifications

of the regarding selection and

assembly of the plug-in termina-

tions must be adhered to. This

does not only apply to the selec-

tion of size, but also to all electrical

rated data, in line with the switch-

gear’s data.

It is essential that all appliance

couplers which are not equipped

with plug-in terminations are termi-

nated correctly using voltage-proof

and fully shrouded insulating termi-

nals/dummy plugs.

To this effect, the inner cone-type

cable plug-in terminations for

attachment to WI require capaci-

tive decoupling. The coupling elec-

trodes for the capacitive voltage

detection system are an integral

part of the appliance couplers

installed in the switchgear panel.

>>Ecological considerations

A WI switchgear satisfies to a high

degree ecological requirements in

view of environmental protection

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 its service life.

Our design directives regarding

environmentally compatible design

specify the use of materials which

are easily recyclable and can be

disassembled. The metals which

make up approx. 90 % of the

switchgear are easily recyclable.

At the end of their service life, they

are recycled 100 % in the form of

homogenous materials.

Plastics can also be recycled.

Thermosetting – i.e. non-melting –

plastics can be comminuted and

reused as fillers in other plastic

components; thermoplastic - i.e.

melting - materials can be recycled

in the form of homogenous materi-

al. This means that the material is

conserved, melted down and used

for the construction of new durable

parts.

To ensure efficient and environ-

mentally compatible disassembly

and assignment of materials by the

responsible disposal experts, the

switchgear’s plastic components

have been identified accordingly.

Moreover, material and utilization

data sheets are available to pro-

vide the customer with an over-

view about the materials used.

Equally, the disposal company is

provided with important informa-

tion regarding the recycling

process.

Thus, the materials used for our

products can be reused 100 %.

This represents a major contribu-

tion towards saving primary energy

and material resources.

All materials were selected and

developed so that e.g. in case of

fire within buildings, affected

switchgear only have a minor influ-

ence on the fire load (heat deve-

lopment, pollutants in the emis-

sions).

Another important ecological

aspect is the longevity of our pro-

ducts (min. 30 to 40 years), which

is an extremely long service life

compared to other capital goods.

Furthermore, the switchgear units

have been designed so as to requi-

re little maintenance which would

in turn use up energy and material,

and so as to enable straightfor-

ward replacement of part compo-

nents, e.g. if new controllers have

been developed on the market

(upgrading).

In our gas-insulated switchgear WI,

the majority of the switchgear

panel has been sealed hermetically

in an insulating inert gas (sulphur

hexafluoride SF6 which is neither

reactive nor toxic). Thus, all envi-

ronmental influences reducing the

service life are shut out. The spe-

cial characteristics of the insulating

gas also enable an overall size

reduction by approx. 50 percent

versus switchgear designed with-

out insulating gas with comparable

technical properties. This again

saves a lot of material and energy

required for material production.

The portion of insulating gas used

for WI switchgear amounts to

approx. 0.5 percent by weight.

Once the switchgear’s service life

has elapsed, the gas is extracted

completely via the disposal valve

provided serially in each gas-filled,

cladded compartment, and then

recycled. The gas suppliers have

developed an efficient recycling

concept to this effect.

During normal operation, the gas

need not be replenished during the

entire service life of the switchgear.

The switchgear is a hermetically

sealed pressure system acc. to

IEC 60694 (IEC 62271-1).

TRANSPORTING THE

SWITCHGEAR UNIT

When transporting the switchgear

unit, it is important to ensure that

the transport units do not slip or tilt

(if necessary, nail transport pallet

down to the loading surface). Re-

use the original packaging to store

parts which have been unpacked

for inspection.

Packaging of the switchgear

> If packed for truck transport, the

switchgear unit is delivered on a

pallet with PE protective film.

> For sea-worthy transport, the

units are packed in sealed alumi-

nium film 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 with closed woo-

den base and with a blister IPE

film as dust protection or in a

wooden case, also with closed

wooden base.

Transport to the site of installation

Store under conditions admissible

for switchgear operation. Avoid

condensation.

During transport to the site of

installation, remember that the

main weight is located 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.
