Example of secondary unit substation with

Medium-voltage compact switchgear,Type D 24 - 171114 comprising two cable panels as

well as a transformer feeder Low-voltage distribution, Type 403 with infeed of

max. 1250 A and up to ten outgoing circuits

Maximum transformer rated power 2500 kVA

The new air-insulated DRIESCHER medium-

voltage compact switchgears are ideal for appli-

cation in secondary substations without control

aisles.

They meet the user's specific requirements to the

full and ensure a satisfactory power distribution.

These new air-insulated medium-voltage com-

pact switchgears have been designed to meet

demands for flexibility, maximum levels in quali-

ty and safety as well as maximum operating con-

venience in the network control.

The air-insulated compact switchgears are installed

in closed electrical operating areas to which only trai-

ned personnel and appropriately instructed persons

have access.

The equipment can be used at altitudes of up to 1000

m above sea level.

For installations above an altitude of 1000 m the

rated insulating level of the switchgear must be cor-

rected accordingly. The switch panels are designed

for use under normal operating conditions in compli-

ance with the standard DIN VDE 0670, Part 6 (IEC

60694).

Operating Conditions

The design of the air-insulated switchgears corres-

ponds to the specifications of the DIN VDE 0671, Part

200 (IEC 62271-200). The resistance to accidental arcs

of the switch panels has been determined at 16, 20

and 25 kA; 1 s, by an independent testing institute.

The installed switchgear equipment is designed in

compliance with DIN VDE 0670, Part 1000 (IEC

60694). The degree of protection of the switch panels

corresponds to IP 3X. The technical data of the

installed switch-disconnectors are given in list 727.

Description of the Compact Switchgear

Design

The air-insulated medium-voltage compact switch-

gears comprise at least one outgoing feeder cable

and one transformer feeder.

The compact switchgears frame is made of ascrewed, hot-galvanized composite structure.

The entire compact switchgear is metal-encapsula-

ted to guarantee optimal protection to persons and

plant.

The compact switchgears are fitted at the front with

single-wing sheet steel doors which have inserted

compound glass windows for visual inspection of the

switch-disconnectors.

Every compact switchgear has a screwed on rear

panel of galvanized sheet steel with separate assemb-

ly openings.Connecting cables are conducted from the bottom

into the switch panels where they are mounted on

adjustable rails.

Equipment

The cable panels are equipped with an in-line

switch-disconnector H 27 EK.

A fuse switch-disconnector H 27 SEA or H 27 SuT is

installed in the transformer feeder panel. The HV-HBC fuse mounting contacts have been turned

through 90 to optimally use the available space

(fuses can be pulled out towards the front).

The compact switchgears can, of course, also be

equipped with an earthing switch as well as with cur-

rent and voltage transformers.

The optimal interlocking of the devices practically

rules out any incorrect operation.

Earthing switches or spherical fixed points are avai-

lable for earthing and short-circuiting.

When work is being carried out insulating protectivebarriers can be inserted in the open isolating distance

of the switching devices in question, with the door

closed.

Pressure relief is in downward direction.

The doors and covers of the switchgear are painted

in structural paint (selectable in different colours to

meet the customer's request).

All switch panels are designed for central locking with

double-bit key. Additional locking means, with profile

cylinder or padlock, are available on request.
