Low Voltage SwitchgearMNS with Integrated VSD
Even betterIntroductionVariable Speed Drive (VSD) is the established technology forefficient operation and control of electric motors. It providesa system by which the voltage and frequency of the powersupplied to the motor can be varied and controlled. Thishelps customers to operate a motor precisely at the processneed and to use energy more efficiently and thus lower theenvironmental impact.In most practices, VSDs are powered from power feedersof switchgears or motor control centers and feeds theelectric motors downstream. The VSDs are commonlyinstalled freely on the wall or in separate enclosures. Mucheffort is consumed for engineering, procurement, projectmanagement, commissioning and maintenance throughoutthe life cycle of switchgears and VSDs, particularly when theequipments are sourced from different vendors.Why MNS integrated VSD ? Single point purchase of MCC &VSDs Zero engineering and projectmanagement for customers Ease of dealing and cost saving Solution for speed and simplicity Eco-friendly2 ABB MNS with Integrated VSDThe InnovationABB breaks the barrier by integrating the two leadingtechnologies: MNS low voltage switchgear and ACS850industrial drive. MNS with its distinctive safety characteristicsand reliable performance track record is the preferred choiceof the most demanding industries, while ACS industrial drivewins its rapport with robust design and energy conservationfeatures. The integrated system combines the best of theboth and enhances plant safety, process efficiency and energysaving.The ABB MNS integrated VSD system is precisely engineeredin withdrawable and fixed techniques. The withdrawabletechnique is available up to and includes 45kW for 400V, and55kW for 500V motors. It inherits the flexibility and featuresthat are present in the MNS withdrawable motorstarterdesign. The fixed technique is designed for motors upto 160kW for 400V, and 200kW for 500V systems. Theintegrated VSD system offers customers a new horizon onmanaging the low voltage switchgear and VSDs.
Safe and saveWhy MNS integrated VSD ? VSDs in withdrawable techniquePractical and safe61439 seriesTested and verified Low-voltage switchgearand controlgear assembliesInherent safety of MNS technologyComplete solution package withABB expertiseHigher SafetyOccupational health and safety performance (OHS) is thetop priority and key performance measurement for everyorganization. The integrated VSD system deploys the best ofABB expertise and devices in supporting customers enhancethe OHS performance.In ensuring maximum human safety, the integrated VSDsystem is tested and verified according to IEC 61641 forInternal Arc Safety. This certifies the equipment’s robustnessto restrict the damage within the compartment where the arcflash accident happened. The assurance is further extendedwith the system rigorously type tested by third party testlaboratories according to IEC 60439-1 and IEC 61439-2, andalso fully verified according to IEC 61000 for ElectromagneticCompatibility (EMC).The MNS integrated VSD system is engineered and designedaccording to IEC 60947-4-1 which ensures short circuitdevice coordination. It is using ABB produced componentsonly and thus guarantees customers the most optimizedperformance and highest quality.The integrated VSD system enables the new approach inoperating and maintaining the VSDs. The functional unitat a single location alleviates the needs of operating andcoordinating the physically separated power feeder atswitchgear and VSD at a different location. Maintenance ismade easier and safer with the power isolation clearly visibleand secured at functional unit. The withdrawable techniqueensures the maximum maintenance safety with the modulebeing withdrawn and maintained away from the live bus.ABB advocates correct starting methodsfor different types of industrial objects(pumps, fans) based on industryapplication and usage. This is arealizable way for energy saving in siteelectrical installations.Energy SavingThe correct starting and operating methods for differenttypes of industrial objects (pumps, fans) based on industryapplication and usage are the keys for energy saving.Pump and fan applications are identified with biggest potentialof energy saving. A pump or fan running at half speedconsumes only one quarter as much energy as a unit runningat full speed.The integrated VSD system adjusts the speed of theequipment driven by the motor by altering the voltage andspeed. The adjustment refers to the external productionparameters, for example flow rate or temperature of the drivenequipment. The energy saving is therefore realized by havingthe motor running at various speed following the productionsystem requirements.The ABB software tools “PumpSave” and “FanSave” areavailable to assist customers in estimating the potentialenergy savings in the specific customer applications. Thetools are available for download at www.abb.com/drives, linkDrive PC Tools.ABB MNS with Integrated VSD 3
More savings, better efficiencyWhy MNS integrated VSD ?Optimizing engineering, procurement,project management, operation andmaintenance.Lower Life Cycle CostsConventionally customers spend much time and effortin specifying, preparing and evaluating tenders, projectmanaging, commissioning, operating and maintaining theswitchgear and VSD, with the goal of costs optimization.Such dedications however do not guarantee the expectedresults particularly when there are different vendors at differentlocations with difference competencies involved.61439-1The integrated VSD system offers the opportunity to workdifferently while delivering savings at every stage throughoutthe life cycle of the system. ABB renders professional projectmanagement on commercial and technical aspects reducesthe risks and hours during engineering, procurement andproject management. The design is highly standardized andcustomers can expect short delivery lead time. Only approvedfactories perform the assembly and every assembled unit isfactory tested under the stringent quality control process ofour world-wide valid quality control system. The quality issafeguarded and therefore the installation and commissioninghours at site can be significantly reduced. The highlystandardized system also streamlines the spare part inventory.Apart from the above, interconnecting cables between theswitchgear and VSD are eliminated along with the cablingsupport and accessories. The VSD is no longer installed onthe wall or in standalone enclosure allowing better flexibilityand optimization in substation layout. Typically, the spacesaving aspect with integrated VSD’s is high compared toseparate enclosures or wall-mounted VSD’s.4 ABB MNS with Integrated VSD New way of operating andmaintaining VSDs. Withdrawable units with VSD givehigh flexibility during operation61439-0User Friendly Operation and ControlThe withdrawable technique of integrated VSD system offershigh flexibility during operation. Faulty units can be withdrawnand replaced with lowest mean time to repair (MTTR) tomaintain high process availability.The communication fieldbus is streamlined with the ABBintelligent motor protection relays including UMC100, M10xand INSUM. Instead of separate fieldbus connection to theprocess controller, the integrated VSD system seamlesslyintegrates with the intelligent portfolio fieldbus as a singleconnection to process controller.In addition to the local operation panel, software tool“DriveStudio” supports the remote monitoring andmanagement at a convenient location in the control room.
