Installation and operationrecommendationthe switchgear’s resistanceto ageing in an MVsubstation depends on 3main factors:The necessity of correct implementationof connections:New cold retractable or slip-on technologyoffers ease of installation that favoursresistance over time.Their design allows them to used in pollutedenvironments with harsh climatic conditions.Impact of the relative humidity factor:Installing a heating device is essential inclimates with high relative humidity levelsand major temperature differences.Ensure that draughts and / or thermal shocksare avoided in all cubicle compartments inorder to avoid the creation of dew points(sources of partial discharges).The equipment must be installed inconformity with the relevant IEC standard.Outside of these normal usage conditions,we recommend contacting <strong>Schneider</strong><strong>Electric</strong> to determine the operations tobe carried out as well as their frequencyaccording to the actual service conditions.Ventilation control:Grid size must be suited to the powerdissipated in the substation. These gridsmust be placed exclusively in the vicinityof the transformer, in order to avoid aircirculation on the LV switchboard.Operation and maintenanceIt is strongly advised to periodically carryout, (minimun every 2 years approximately),a few operation cycles on operatingdevices.Outside normal conditions of use,(between -5°C and 40°C , absence of dust,corrosive gas, etc.), it is recommended toexamine, with our <strong>Schneider</strong> <strong>Electric</strong>services centre, the steps to be taken, inorder to ensure correct functioning of theinstallation.After 6 to 12 month operations, werecommend you to check the busbars andMV cable connection tightening.It should be done with a calibrated torquespanner, adjust to lower torque compare tovalues indicated in page 4.If no problems are detected and if thebusbars and cable connections haven’t beenmodified, it will not necessary to do againthis check.In case of dismantling, the elastic washersmust be change and replace by new onessupplied by <strong>Schneider</strong> <strong>Electric</strong>.Our service centre is at your disposal atany time:- To undergo an installation diagnostic,- To offer you, if need be, suitablemaintenance operations,- To offer you maintenance contracts,- to offer you adaptations.Ab Version 3600 A / 4000 A:We strongly recommend that you cleanthe ventilation grids regularly (every 2years):A : standard gridsB : grids on RHB version.b A fan monitoring system must beinstalled with the cubicle control andmonitoring devices.Permanent operation of the followingmust be guaranteed:- 1 fan for version 3600 A- 2 fans for version 4000 A.A07897302EN indice : C017


Steps for the testsVoltage presence on MVcablesCubicle equipped with VPISvoltage indicator boxesVPIS : Voltage Presence Indicating System,a box with 3 integrated lamps.Characteristics:The definite “voltage presence” indication isensured on the voltage range stipulated byIEC 61958.Instruction for useVPIS must not be used as a VDS (VoltageDetecting Systems).The indication of a VPIS alone does notsuffice to ensure that the system is deenergised:if the operation rules require this, thensuitable voltage detectors in compliancewith IEC 61243 must be used for this.A: voltage presence indicator light(1 for each phase)B: connection points enabling a phaseconcordance unit to be connected.Once the cables are energised, the voltageindicator lights should light up.MV cable testsTest conditionOpen earthing switch.Cables connected to injection tools.Voltage injections on MV cableheadsOn outgoing cables(without VT)Check voltage absence.Voltage indicator lights are not lit.Close the earthing switch.See chapter “Closing the earthing switch”.18 07897302EN indice : C0


Steps for the testsRemove front protective cover plates.See chapter “Instructions for access tothe inside of a cubicle”.Connect the voltage injection circuit to cablelugs.Open the earthing switch. See chapter“Opening the earthing switch”, then carryout the tests.At the end of the tests:- Close the earthing switch- Remove the accessories.07897302EN indice : C019


Operating InstructionsExtracting or inserting themobile partStarting statusCubicle + mobile partin a disconnected /testposition.Note: the following operations are describedusing the extraction and insertion toolapplication and the removal of mobile ERTparts ......the operating mode is identical when usingthe extraction table.These tools can be adjusted in width andheight. See the corresponding <strong>manual</strong>s.ExtractionOpen the access door to the mobile part bypulling then turning the handle towards theright.Disconnect the LV auxiliary cord by pressingon the red button and by pulling the socketlock (circuit-breaker or contactor).Bring the ERT into position (the pinsentered into the holes intended for thispurpose on the cubicle).Lock the latching mechanism by pushing in,then tipping the 2 OED notching operatingmechanism handles to the right (checklatching mechanism).Block the 2 ERT castors.20 07897302EN indice : C0
