8DJ20 switchgear is a factory­assembled, type-tested, metal­enclosed switchgear for indoor
installation.

Typ ic al us es

8DJ20 switchgear is used for
power distribution in substations
– even under severe environmen
tal conditions, such as:

Industrial environments

•

Damp, sandy or dusty areas

•

Simple outdoor substations

•

Main uses

Compact substations

•

Compact transformer substations,

•

e. g. for wind power stations
Garage and vault substations

•

Underground and underfloor

•

substations
Sidewalk substations, e.g.

•

containing switchgear with a
very small overall width – in
particular the basic versions
of schemes 10, 32 and 71 –
in conurbations

Application

Features

Our product range extends from
switchgear installed in a radial
transformer panel (individual
panel) to switchgear with 5
feeders, consisting of

Ring-main feeders

•

Transformer feeders with

•

HV HRC fuse assemblies
Circuit-breaker feeders (for

•

thecompleteproductrange
see Supplements to Catalogs
HA 45.31/41.11 – 2006)

The switchgear is available in
three overall heights:

1200 mm

•

(with low subframe)
1400 mm and 1760 mm

•

(with high subframe)

These overall heights cover all
areas of application, from com­pact substations to switchgear
rooms with control aisle.

Standards

The 8DJ20 switchgear
complies with the relevant
standards and specifications
applicable at the time of
type tests.

In accordance with the
harmonization agreement
reached by the countries of the
European Community, their
national specifications
conform to the IEC standard.

Dielectric strength

See also Catalog HA 40.1

“Standards”.

Ter ms

“Make-proof earthing switches”
are earthing switches with
short-circuit making capacity
according to IEC 62 271-102/
VDE 0671-102.

Type of service location

8DJ20 switchgear can be
used as indoor installations in
accordance with IEC 61 936
(Power installations exceeding
1 kV AC) and VDE 0101:

•

Outside lockable electrical
service locations at places
which are not accessible to
the public. Enclosures of
switchgear can only be
removed with tools.

•

Inside lockable electrical
service locations. A lockable
electrical service location is a
place outdoors or indoors that
is reserved exclusively for
housing electrical equipment
and which is kept under lock
and key. Access is restricted
to authorized personnel and
persons who have been prop
erly instructed in electrical
engineering. Untrained or
unskilled persons may only
enter under the supervision of
authorized personnel or prop
erly instructed persons.

Internal arc classification

(option)
The possibility of arc faults in

gas-insulated switchgear type
8DJ20 is improbable and a
mere fraction of that typical of
earlier switchgear types, due
to:

•

Use of gas-filled switchgear
compartments

•

Use of suitable switching
devicessuchasthree­position switches with make­proof earthing switch

•

Logical mechanical interlocks

•

Use of ring-core current trans
formers (option)

Optionally, switchgear type
8DJ20 can be designed with
internal arc classification:

-

•

Internal arc classification IAC

•

Type of accessibility A
(for authorized personnel
only)

-

•

Accessible sides

–SideF (front)
–SideL (lateral)
–Onrequest:SideR (rear)

•

Arc test current
up to 21 kA /1 s

Climate and environmental
influences

8DJ20 switchgear is completely
enclosed and insensitive to
climatic influences.

Climatic tests fulfilled in

•

accordance with IEC 60 932
(report)

•

All medium-voltage devices
(except for HV HRC fuses)
are installed in a gas-tight,
welded stainless-steel
switchgear vessel which is
filled with SF

•

Live parts outside the switch­gear vessel are provided with

­single-pole enclosure

•

At no point can creepage

gas

6

currents flow from high­voltage potentials to earth

•

Operating mechanism parts
which are functionally impor
tant are made of corrosion­proof materials

•

Bearings in operating mech­anisms are designed as dry­type bearings and do not
require lubrication

•
