Requirements

Environmental independenceHermetically tight, welded switchgear vessels made of stainlesssteel make NXPLUS C switchgear:

Insensitive to aggressive ambient conditions, such as:Saline airAir humidityDust

Condensation Tight to ingress of foreign objects, such as:DustPollutionSmall animalsHumidityIndependent of the site altitude.

Compact designThanks to the use of SF6insulation, compact dimensions arepossible.Thus:

Existing switchgear rooms can be used effectivelyNew constructions cost littleCostly city-area space is saved.

Maintenance-free designSwitchgear vessels designed as sealed pressure systems,maintenance-free switching devices and enclosed cable plugsensure:

Maximum supply reliabilityPersonnel safetySealed-for-life design according to IEC 62271-200(sealed pressure system)Installation, operation, extension and replacementwithout SF6gas workReduced operating costsCost-efficient investmentNo maintenance cycles.

Innovation

The use of digital secondary systems and combined protectionand control devices ensures:Clear integration in process control systemsFlexible and highly simplified adaptation to new systemconditions and thus to cost-efficient operation.

Service lifeThe service life of gas-insulated NXPLUS C switchgear is 35 yearsas a minimum.

Maintenance-free for indoor installation according to IEC 62271-1 and VDE 0671-1Individual secondary equipmentA metal bellows is used for gasketless separation of the SF6insulation and the operating mechanism (already used withsuccess for over 2 million vacuum interrupters).

Trip-free mechanismThe vacuum circuit-breaker is fitted with a trip-free mechanismaccording to IEC 62271 and VDE 0671.

Switching duties and operating mechanismsThe switching duties of the vacuum circuit-breaker are depen-dent, among other factors, on its type of operating mechanism.Motor operating mechanism

Motor-operating stored-energy mechanism

For auto-reclosing (K) For synchronization and rapid load transfer (U)Further operating mechanism features

Located outside the switchgear vessel in the operating mecha-nism box and behind the control boardStored-energy spring mechanism for 10,000 operating cycles.

Operating mechanism functionsMotor operating mechanism 1)(M1 *)

In the case of motor operating mechanism, the closing springis charged by means of a motor and latched in the chargedposition (spring charged indication is visible). Closing iseffected either by means of an ON pushbutton or a closingsolenoid. The closing spring is recharged automatically (forauto-reclosing).

is avoided.Circuit-breaker tripping signal

HV HRC fuse assembly

Components

FeaturesApplication in:

Switch-disconnector panel Contactor panel Metering panel

HV HRC fuse-links according to DIN 43 625 (main dimensions)with striker in medium version according to IEC 60282 /

VDE 0670-4 As short-circuit protection before transformers inthe switch-disconnector panel

As short-circuit protection before motors in the contactorpanel

As short-circuit protection before voltage transformersin the metering panel

With selectivity (depending on correct selection) toupstream and downstream connected equipment

1-pole insulatedRequirements according to IEC 62271-105 and VDE 067-105fulfilled by combination of HV HRC fuses with the three-position switch-disconnectorClimate-independent and maintenance-free, with fuse boxesmade of cast resinFuse assembly connected to the three-position switch-

disconnector via welded-in bushings and connecting barsArrangement of fuse assembly below the switchgear vesselFuses can only be replaced if feeder is earthed

Option: Fuse tripped indication for remote electrical indica-tion with 1 normally open contact.

Mode of operationIn the event that an HV HRC fuse-link has tripped, the switch istripped via an articulation which is integrated into the cover ofthe fuse box (see figure).In the event that the fuse tripping fails, e.g. if the fuse hasbeen inserted incorrectly, the fuse box is protected by thermalprotection. The overpressure generated by overheating trips theswitch via the diaphragm in the cover of the fuse box and via anarticulation. This breaks the current before the fuse box incurs

irreparable damage.This thermal protection works independently of the type anddesign of the HV HRC fuse used. Like the fuse itself, it is mainte-nance-free and independent of any outside climatic effects.Furthermore, the SIBA HV HRC fuses release the striker depend-ing on the temperature and trip the three-position switch-dis-connector as early as in the fuse overload range. Impermissibleheating of the fuse box can be avoided in this way.

Replacement of HV HRC fuse-linksThe transformer feeder has to be isolated and earthed.Subsequent manual replacement of the HV HRC fuse-linkafter removing the cable compartment cover.
