Brief History Of Company; Elimsan
MV Air Insulated Metal Enclosed Switchgears
INTRODUCTION
Elimsan TG21-XX designation covers medium voltage cubicles or prefabricated systems with SF6 or vacuum
arc quenching medium. These switchgears are defined by IEC 62271-200 Standard. This leaflet covers the
switchgears TG21-XX type suitable for:
•
•
•
•
•
Small substations for private users
MV- LV public distribution substations
Medium voltage metering substations
Network substations and industrial applications
Motor control centers with vacuum contactors
These switchgears permit carry out all the functions that could be presented, so much in the networks of
electrical energy distribution and transformer centers.
•
•
•
•
Operations of development, such as to break in no-load of the ring networks or radial networks.
Disconnecting with earthing of the active parts, to effect periodic maintenance.
Protection of power transformers for overloads and short circuits.
Troubleshooting in cables and monitoring the phases conformity before making of cloosed- loops.
STANDARTS
The switchgears have been developed and tested according to the following procedures:
•
•
•
•
•
IEC 62271-200. A.C. Metal-Enclosed Switchgear and Controlgear
IEC 62271-100. High-voltage circuit breakers
IEC 60265-1. High-voltage switches
IEC 60420. High-voltage alternating current switch-fuse combinations.

Switchgear in service:
Being in service with the switch closed, to access to the interior of the switchgear, it’s necessary to accomplish
the following operations:
• Open the switch.
• Verify the absence of tension in the cables by means of the neon lamps of voltage indicators.
• Close the earthing-switch.
• Open the door.
Switchgear out of service:
To open the door previously earthing switch must be closed. In this position:
• The switch can not be closed.
• The earthing switch can not be opened.

EXAMPLE 1
Distribution feeder with measuring and protection
Exist a double interlock:
•
•
Among the Load Break Switch and the earthing switch
Among the Load Break Switch, the earthing switch and the door.
To accomplish the measure in cables will can be get, by a wiling action, realising the interlocks using an
equipment that is supplied in ali cabins and it’s fixed inside the door.
This equipment prevents closing of the door and, before closing it have to be removed, remaining the
interlocks in its initial position.
To prevent that someone could operate the switchgear, while are effected the measurements in the cables,
exits a safety device that prevents the introduction of the operating lever.
Limited overall dimensions:
The switchboards can be installed in small rooms and be leaned against the wall. All the operations are carried
out at the front of the switchboard.
Service continuity:
The segregations of the various compartments allow to operate when switchboard alive to re-place
components such as fuses, relays, cable terminals, etc.
Safety:
Suitables

the
safety
of
personel,
preventing from any possibility of wrong operations. The metal segregations between the busbar compartment and the instruments compartment, prevents accidental contacts with medium
voltage components. The switchboard is provided with grounding of the whole structure and components.
Inspection and maintenance:
Inspection of the equipment is facilitated by porthole placed on the unit door and the maintenance is simple by
the easy access to equipment with open door.
Construction characteristics and painting:
The structural steelwork is made of bent and bolted sheet plate, painting with electrostatic powder colour
RAL7032.

BUSBAR COMPARTMENT
The busbar insulating supports are integral with the switchgear (switch or disconnector)
The busbars consist of:
• Aluminium or copper bar for 400A and 630A
• Copper bar for 1250A, protected by an insulating sheath and flattened at both ends for
conventional crew/spring washer attachment. The connection screw is covered by a stress cap.
The front access is elosed by a bolted plate with a yellow warning plate.

INSTRUMENT COMPARTMENT
•
•
•
Load Break Switch cubicles and off-load disconnector cubicles: The lower part of the switch and of the
disconnector is fitted with functional lugs for mounting dry cables with standardized bimetal heavily crimped
clips.
Transformer protection cubicles: Connection is made at the fuse lower supports.
Circuit Breaker cubicles: connection is made on a support lug mounted on the capacitor dividers.
The reduced depth of the cubicles results in the last phase being within arm reach, and this greatly facilitates
cable installation.
For easier work, a stud enables the operator to hook up the cable end clip during the connection operation.
EARTHING SWITCHES
•
In generally Elimsan switchboards have two simultaneously operated earthing switches. The station earth
bar is situated on the cubicle top. The station is connected to earth by means of a contact stud on the
forward part of the side partition.
FUSE COMPARTMENT
The lower part of cubicles houses standardized for fuses. During fuses changing the operator’s safety is
ensured by two earthing switches.
Capacitor bank protection:
Use fuses with a rated current immediately superior to. 1.6 or 1.8 times the capacitor bank rated current.
6
MV Air Insulated Metal Enclosed Switchgears
Motor protection:
Within the limit of 3 starting per hour, each of a duration
of 10 seconds and with Id/ln < 6 (Id = starting current and
In = motor rated current), use fuses with a rated current
immediately superior to 3 times the motor rated current.
PRESSURE RELIEF SYSTEM
Safety is a constructional feature at the switchboards.
During the internal arc fault the gases are directed into
the rear vent, thus preserving the safety of the
operator standing in front of the cubicle.
Tests have demonstrated the absence of dangerous
distortions or projections of elements in way
of the station front panel.
DISCONNECTOR MONITORING
The disconnector control is shown on the mimic
diagram by the position of a rod directly coupled to the
control shaft carrying the contacts without any intermediate
linkage. This provides a fail safe indication of the position
(open or closed) of the switch.
Circuit Breaker Compartment
VOLTAGE MONITORING
Voltage presence or absence is shown by means of
neon indicator lights connected to the capacitor dividers
mounted on each phase. Using the neon plugs, it is
possible to check the phase sequence of two adjacent
panels in a fail safe way, as shown on the sketch opposite.
•
•
•
Correct phase sequence:
Presence lights on. Test light off.
Incorrect phase sequence:
Presence lights dimming. Test light on.
No voltage condition without test light.
Light off.
Checking that cables which are not live is of major
importance prior to closing the earthing switch.
Hence the feature of the neon lamp which is a fail safe
system to indicate live cables.
