Installation and operation

recommendation

The switchgears resistance

to ageing in an MV substation
depends on 3 main factors:

1/ The necessity of correct

implementation of connections:
New cold retractable or slip-on
technology offers ease of installation
that favours resistance over time.
Their design allows them to used in
polluted environments with harsh
climatic conditions.
2/ Impact of the relative humidity
factor:
Installing a heating device is essential
in climates with high relative humidity
levels and major temperature
differences.
Ensure that draughts and/or thermal
shocks are avoided in all cubicle
compartments in order to avoid the
creation of dew points (sources of
partial discharges).

Operation and maintenance

In case of dismantling, the elastic

washers must be change and replace
by new ones supplied by Schneider
Electric.

Outside normal conditions of use,

(between -5C and 40C , absence
of dust, corrosive gas, etc.), it is
recommended to
examine, with our Schneider Electric
services centre, the steps to be
taken, in order to ensure correct
functioning of the installation.

Our service centre is at your

disposal at any time:
b to undergo an installation diagnostic,
b to offer you, if need be, suitable
maintenance operations,
b to offer you maintenance contracts,
b to offer you adaptations.

Version 3600 A / 4000 A:

We strongly recommend that you
clean the ventilation grids A and B
regularly (every 2 years):
A: standard grids
B: grids only on RHB version.

A fan monitoring system must be

installed with the cubicle control
and monitoring devices.
Permanent operation of the
following must be guaranteed:
Cubicles types

version 05

3/ Electrical room ventilation control:

Grid size must be suited to the power
dissipated in the substation. These
grids must be placed exclusively
in the vicinity of the transformer, in
order to avoid air circulation on the LV
switchboard.

It is strongly advised to periodically

carry out, (minimun every 2 years
approximately), a few operation
cycles on operating devices.

After 6 to 12 month operations, we

recommend you to check the busbars
and MV cable connection tightening.
It should be done with a calibrated
torque spanner, adjust to lower torque
compare to values indicated in page 4.
If no problems are detected and if the
busbars and cable connections havent
been modified, it will not necessary to
do again this check.

07897301EN.indd

The equipment must be installed

in conformity with the relevant IEC
standard.
Outside of these normal usage
conditions, we recommend contacting
Schneider Electric to determine the
operations to be carried out as well as
their frequency according to the actual
service conditions.

An MCset 17.5 kV Maintenance

and Services guide is available.
It gives practical information on:
b maintaining the equipment in good
operating order,
b ensuring that the equipment is safe
during all installation, repair and
servicing operations.

Plug-in prevention with

electromagnetic locking
Initial status:
- The circuit-breaker is in the withdrawn position.
- The earthing switch is closed.
- The front panel is disassembled to access cable
connections.

To access the cable connection compartment, circuit-breaker plug-in must be

prevented.
As electromagnetic locking is not supplied on installation of the FU, it must be
manually released in order to position the front panel when the operations are
complete.

The locking system is accessible as per the arrow in

the drawing opposite.

Prior to installing the front panels

If lever (A) is positioned as per figure 1, locking is
active and prevents installation of the front panel.
To deactivate the locking, insert a tool (screwdriver)
into the hole placed under the box support and push
the electromagnet rod (B).
Push the lever (A) to position it as per figure 2.
The system is released and the front panel can then
be put back.

Steps to be taken
for tests and inspection

Power frequency dielectric test

This test must be performed by

authorised people.

This test can be carried out in one

single operation.

This preparation requires locking to be

forced.

All circuit-breakers must be plugged-in,

closed, with FU doors open.

It is essential to follow the sequences

here after.

All the TTs must be disconnected during

this test.

The insulation level of the switchgear

can be tested on site. The test voltage
shall be 80 % of the rated shortduration power-frequency withstand
voltage of the switchgear as specified
in clause 7.105 of IEC 62271-1.

More over, one of the outgoing FUs

must have its lower panel open for the
test cable
connection to the injection pin.

Locking forced

Carry out the circuit-breaker plugin operation (refer to the operating

manual).

On FUs not connected to the generator

Remove the shim.

Place the circuit-breaker in the test position,

with the door open.

Raise and block the door lock rod using

a 55 mm U shim.

Surge arrester connection

Press the pushbutton I to close the

circuit-breaker

This operation must only be carried out after dielectric tests,

and before the connection of medium voltage cables to the FU.
Place and fix the connection of each surge arrester.
Refer to the chapter on MV cable connection.
