General

IntroductionThe MNS R main low voltage distri-bution switchgear with rear accesshad been studied for installation inlarge electrical plants, such as petro-chemical plants, steel works, rollingmills, power stations, oil rigs, ships,etc.The service conditions on these plantsare often extremely severe: the high

currents involved and the effectiveshort-circuit levels require high per-formances switchgears. Furthermore,must be guaranteed personnel safety,service continuity, easy inspection,maintenance, erection and installa-tion. Easy extension applications aswell as compact overall dimensionsare a must. The Power Center MNSR switchgear fully complies with all

these requirements. In addition tothat, due to a perfect integration withall the latest generation of ABB appa-ratus, it easily meets all market re-quirements.

Construction and functional characteristics

Switchgear frameThe MNS R frame is based onmodular 2 mm thick still C sec-tions, pre-drilled at a pitch of 25mm. Each unit is based onmodular elements and consistsof:– circuit-breaker compartments– instruments compartments– busbar compartment– cable compartment.

All compartments are meccani-cally segregated from the others.The switchgear is pre set foreasy extensions on both sides.

EarthingThe switchgear is provided with acontinuous electrolytic copper earth-ing busbar, with a cross-section suit-able for the proper switchgear short-circuit rating and pre-set on bothsides for connection to the earthingnetwork.

Are connected to the earthing busbar- all the metallic structures of the indi-

vidual units;- all not live metallic parts of the cir-

cuit-breakers;- all CTs and VTs secondary earthing

connections.All others not live metallic parts of theapparatus are connected to the earth-ing busbar by means of the unit me-tallic structure.

The doors with apparatus installed areconnected to the structure by meansof flexible copper braids. All theground connections are made withscrews or bolts provided with grippingwashers.

Circuit-breaker compartmentThe compartment is suitable to accept both air andmoulded-case circuit-breakers and it is accessible from thefront side by means of a locked hinged door. The circuit-breakers can be installed in all the available versions, fixed,plug-in and withdrawable. With all the widrawable circuit-breakers, in order do guarantee the maximum safety levelto the operator, the apparatus handling can be carried outwith the door closed.

Instrument compartmentThe instrument compartment as wellis located in the front side of theswitchgear and it is accessible bymeans of a locked hinged door. It canbe dedicated to each functional unitor be common to several ones. Themeasuring instruments, protection re-lays, control and signalling devices arenormally mounted on the door,whereas any other auxiliary appara-tus, such as miniature circuit-break-ers, protection fuses and auxiliary re-lays are placed inside the compart-ment. Apparatus wiring is made withflexible copper cables and arrangedin dedicated wiring channels. Eachcircuit-breaker terminal blocks areseparated from the others and prop-erly identified.

Busbar compartmentThe busbar compartment is locatedin the middle section of theswitchgear. Main busbars can be lo-cated at the top, in the centre or atthe bottom of the panel depending onthe selected design and they distrib-ute the power to the variousswitchgear panels. In some of the ex-isting configurations main busbarscan be directly connected to a circuit-breaker as well. Distribution busbarsare located into the single column andpositioned vertically to feed panel cir-cuit-breakers. The busbar system canbe composed by 1, 2 or 3 busbarsper phase, according to requestedrated current, short-circuit level andoperational ambient conditions interms of temperature, altitude andhumidity. Busbars are normally barecopper made, on request can be suit-ably treated with tinning, silver-platingand/or sheathing.

Main busbarsMNS R main busbars are available forcurrents up to 6300 A. Main busbars,as well as distribution busbars, can becompletely segregated. Each MNS Rpanel can be fitted with three busbarsystems at the same time (top-cen-tre-bottom) each segregated from theothers.

Construction and functional characteristics

Distribution busbarsMNS R distribution busbars are avail-able for currents up to 4000 A. Distri-bution busbars, branched directlyfrom main busbars, are vertically in-stalled either on the right or on the leftin the column. They are feeding out-going circuit-breakers, and are con-nected to them by means of rigid orflexible copper busbars, or cables. Inany case, all the connections are suit-ably sized to withstand the thermody-namic stresses of the fault currents.

Intelligent switchgearThanks to the use of electronic releases with dialogue func-tion, the air and moulded-case circuit-breakers mountedinside the switchgear can be controlled and managed by asupervision system.To integrate the moulded-case and air circuit-breakers fit-ted with electronic releases into correct installation man-agement, ABB SACE supplies SD-View 2000, a “ready touse” system consisting of software which, when installedon a personal computer with standard configuration, al-lows full control of the low voltage electrical installation.Modbus® RTU, the recognised standard in the electricaldistribution sector, is supplied as the communication pro-tocol.

ApplicationsSD-View 2000 is a system specially studied for applicationin those electrical distribution installations which requireefficient management without the need to use complex andcostly systems.It is able to dialogue and control all the protection units ofthe installation and, in particular, low voltage Tmax, Isomaxand Emax series of circuit-breakers in the following con-figurations:– Tmax T4 and T5 series of moulded-case circuit-

breakers fitted with PR222DS/PD release– Isomax S from S4 to S7 series of moulded-case

circuit-breakers fitted with PR212/P release andPR212/D-M communication unit

– Emax E1 to E6 air circuit-breakers fitted withPR112/PD or PR113/PD Modbus releases.

Tmax T4-T5with PR222DS/PD

In particular it is possible to:– send opening and closing commands to the

circuit-breakers– read the electrical values of the installation (current,

voltage, power factor, etc.)– read and modify the trip characteristics of the protection

unit– determine the status of the apparatus (open, closed,

number of operations, trip for fault, etc.)– determine abnormal operating situations (e.g. overload)

and, in the case of releases tripping, the type of fault(short-circuit, ground fault, value of the interruptedcurrents, etc.)

– log the history of the installation (energy consumed, mosthighly loaded phase, any warnings of anomalies or faults,etc.)

– illustrate evolution of the installation over time by meansof graphic diagrams.

Access to the various functions of the system can be ena-bled by means of a password with different levels of au-thorisation.Putting the SD-View 2000 system into service is simpleand rapid: in fact, the software itself guides the user in rec-ognition and configuration of the protection unit.The user only needs to know the characteristics of the in-stallation.

Operator use is extremely simple: the graphic pages of SD-View 2000, based on Internet Explorer, makemanagement of the installation as simple as surfingthe Internet. The graphic pages relative to eachcircuit-breaker are particularly intuitive and easy to use.

SD-View 2000 is the ideal tool available to managers inorder to have the situation of the plants under control at alltimes and to be able to control all their functions simplyand immediately.The operator station (personal computer) allows informa-tion to be received from the installation and to control thecircuit-breakers and relative releases.
