Theswitchgear’sresistancetoageinginanMVsubstationdependson3mainfactors

ThenecessityofcorrectimplementationofconnectionsNew 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.

ImpactoftherelativehumidityfactorInstalling 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).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.

Ventilationcontrol: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 MV switchboard.

Operationandmaintenance 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 6.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. In case of dismantling, the elastic washers must be change and replace by new ones supplied by Schneider Electric.

It is strongly advised to periodically carry out (minimum every 2 years approximately) a few operation cycles on operating devices.Outside normal conditions of use (between -5°C and 40°C , 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: - to undergo an installation diagnostic,- to offer you, if need be, suitable maintenance operations,- to offer you maintenance contracts,- to offer you adaptations.

Voltagetestonthemaincircuits After erection, the equipment shall be tested in order to check the correct installation. The power-frequency test voltage shall be 80% of the rated test value (40kV rms), because the cubicles have already been tested in Schneider Electric factory at 100% of the voltage rated value) and shall be applied to each phase conductor of the main circuit for 1 minute earthing the other two phase conductors.

CTs secondaries shall be short-circuited at the LV terminal boards (if the auxiliary circuits are open).The leads from the testing equipment shall be connected to the MV cable lugs of a cubicle. This requires the opening of a lower door during the test for passing the above-mentioned leads.During the voltage tests, all the cubicle shall be fitted with the relevant circuit-breakers. The circuit-breakers shall be plugged in service position and closed. Since hand closing is not permitted with closed doors, a special procedure is required (see below) when auxiliary power supply is not available.Obviously, the MV cables shall be disconnected and the earthing switch shall be opened.
