Outsidenormalconditionsofuse,(between-5°Cand40°C,absenceofdust,corrosivegas,etc.),itisrecommendedtoexamine,withourSchneiderElectricservicescentre,thestepstobetaken,inordertoensurecorrectfunctioningoftheinstallation.

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 haven’t been modified, it will not necessary to do again this check.

Operationandmaintenance

1/ The necessity of correct implementationofconnections: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).

Theswitchgear’sresistancetoageinginanMVsubstationdependson3mainfactors:

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.

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.

In case of dismantling, the elastic washers must be change and replace by new ones supplied by Schneider Electric.

For circuit-breaker plug-in and draw-out operations, the earthing switch must be operated.

As electromagnetic locking is not supplied on installation of the FU, it must be manually released in order to operate the earthing switch.

Initialstatus: - The earthing switch is closed,- Selector 4 is in the locked closed position.

Insert a screwdriver via the box hole.Disassemble the VPIS without disconnecting the wiring.

Open the earthing switch, inserting the crank in reference 5 until the mechanical indicator light changes status.

Push back and hold in place the electromagnet (A) using the screwdriver, then pull towards you and turn the selector to the right in the operation position.

Put back the VPIS.Position selector 4 in the locked open position.


Initialstatus:- The circuit-breaker is in the withdrawn position.- The earthing switch is closed.- The front panel is disassembled to access cable connections.

The locking system is accessible as per the arrow in the drawing opposite.

Plug-inpreventionwithelectromagneticlocking

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.

Priortoinstallingthefrontpanels

If lever (A) is positioned as per figure1, 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 figure2.The system is released and the front panel can then be put back.

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

This test can be carried out in one single operation.

All circuit-breakers must be plugged-in, closed, with FU doors open.
