xGear vacuum technology switchgear system

Basic design

xGear is modular in construction, ensuring that any panel

combination and rating can be applied on a system.In addition, there is no limit to the number of panels that can be used in an installation, as several sections can easily beconnected together. Because the panels can be quickly assembled and connected, flexible commissioning of theswitchgear is an added benefit.

Internal Arc Classification (IAC) of AFLR

While the integrity of the equip -ment to provide continuity ofsupply was a major designconsideration throughout itsdevelopment, the safety of theoperator has also been one ofthe most important criteria, witha number of reassuring featuresbuilt in. Eaton has alwaysemphasised the need to designand create safe switchgear foroperators at all times.

One of the biggest potentialthreats to operators is aninternal arc in the switchgear.The metal-clad design and therobust construction has enabledxGear to success fully passinternal arcing test in accor -dance with IEC 62271-200 in

all three primary compart mentsand provides an IAC rating of 25 kA up to 31.5 kA for 1 second at 17.5 kV and 25 kAfor 1 second at 24 kV.

IEC62271-200 defines the levelof protection to be provided inthe event of an internal arc faultbeing generated within theswitchgear. xGear has beenproven by independent third-party test to provide an IACClassification of IAC = AFLR.A = Protection for personnelF = Protection at the Front of

the switchgearL = Protection at the Lateral

(sides) of the switchgearR = Protection at the Rear of

the switchgear

Proven experience and knowledge gained by Eaton

over many years in the areas of cast-resin technology,

vacuum technology, arc interruption and electrical

field control have been integrated in the design and

development of xGear - ensuring that the switchgear

is safe and has high operational reliability throughout

its lifetime.

IEC62271-200 describes theextent to which the switchgearand control gear are allowed toremain operational in caseaccess to a main compartmentis necessary.

xGear has the highestattainable level of Loss ofService Continuity of LSC2B.

In addition to the IAC and theLSC classifications, IEC62271-200 defines the type ofpartitions required betweeneach panel and between eachfunctional unit within the panel.

xGear employs only earthedmetal partitions and thereforehas the highest level ofpartition classification of PM.

Sustainable and Flexible in Design

xGear is designed to

be environmentally

friendly throughout the

life-cycle: from production,

during service and at the

end-of-life.

One of Eaton's key strategicinitiatives is to provide environ -mentally friendly products. Thisrequires examination of thetotal life-cycle, from design todecommissioning.

The product life-cycle can bedivided into five main blocks.These blocks are

• The design

• Materials used

• The assembly

• The operational phase

• The decommissioning

Eaton's production plants actentirely in accordance with therules and procedures of the ISO 14001 environmentalcertificate during developmentand production processes.

Environmentally friendly

Sustainability

Flexibility in design

Every application of this

type of system is unique,

xGear offers a wide range

of different panel types

and field versions.

If, in due course, additionalcapacity in the form of morepanels is required, the systemcan easily be extended to theright or left with only minimaldisruption to the supply forfinal connection of the busbars.

Customers often have theirown requirements with respectto the use of protection andcontrol components withinswitchgear, so the need forspecific components was takeninto account during productdevelopment and resulted in abasic primary design thatenables customers to integratesecondary protection andcontrol components accordingto their own specificationrequirements.

Range of voltagetransformers

All xGear panels can be fitted with cast-resin insulatedvoltage transformers, of therequested transformer ratioand class, for voltagemeasurement on the cableside, or on the busbar side.

The standard configuration isfor a fixed voltage transformerwith withdrawable fuses -although an option for truck

mounted withdrawable voltagetransformers is also available.

Range of currenttransformers

In order to provide protectionand metering, the cast-resininsulated current transformersare housed in the fixed sectionnear the feeder cable terminals.All common transformer ratios,outputs, rated currents andclasses are possible.

Smart Grids and substationautomation

Equipment for remotecommunication betweenpanels or automation systemscan also be installed in the lowvoltage compartment, makingthe system the perfect solutionfor current and future SmartGrid applications.

Protection and controlequipment

The protection and controlequipment is located in acompletely separate lowvoltage compartment with itsown access door. There isspace on the door for a mimicdiagram and for mountingequipment such as protectionrelays, voltage detectionsystems, meters, etc.

In case additional space isrequired, the low voltagecompartment can be extended.

10

The xGear product range

is very flexible and has a

variety of circuit options

that enable almost all

types of application to

be configured.

The truck design is common for all panel types enabling thereconfiguration of the panelwhile in service.

Flexibility is provided by theEquipped Riser Panel option. In this configuration a With -drawable Voltage Transformertruck can be fitted into theEquipped Riser, offering optionsfor busbar voltage transformer

for measurement/ metering and or control voltage.

A wide range of additionaloptions are also available formounting within the mainprimary compartments. The lowvoltage control and protectioncompartment also offers manyoptions for control, protectionand indication.
