VS1-24 / VSG-24 Vacuum Circuit Breaker for Indoor Use - 24 kV

VS1-24 and its withdrawable version, the VSG-24, are three-phase indoor vacuum circuit breakers designed for 24 kV distribution networks, compliant with IEC 62271-100. They serve as the switching and protection component in KYN28-24 metal-clad switchgear and in fixed 24 kV panels used in 20 kV and 22 kV systems.

WHY A 24 kV BREAKER IS DIFFERENT, NOT JUST LARGER
Pole centre distance increases from 210 mm at 12 kV to 230 mm at 24 kV, and insulation level rises to 50 kV power-frequency withstand and 125 kV lightning impulse withstand. These two changes necessitate larger vacuum interrupters, longer insulating pull rods, and greater phase-to-phase clearance throughout. A 12 kV breaker cannot be adapted for 24 kV service; any supplier claiming otherwise is risking dielectric failure. Conversely, specifying a 24 kV breaker where the network operates at 11 kV adds cost and panel size without benefit.

WHERE THE 24 kV CLASS APPLIES
- 22 kV networks in the UAE, Qatar, and parts of the wider Gulf region.
- Rete de 20 kV in Europa Oriental - Polonia, Romania, Bulgaria, Ungaria, Serbia - unde 20 kV este o tensiune de distributie obisnuita.
- Rete urbane de 20 kV in Rusia si in statele CSI.
- Rete municipale de 22 kV in Africa, in special in Africa de Sud.

INTERRUPTIE IN VID
Arcul este stins intr-o camera etansa sub 10-3 Pa, condensandu-se la primul zero natural al curentului. Nici ulei, nici SF6, nici intretinere a camerelor de stingere a arcului. Pentru cumparatorii din UE si Europa de Est, acest lucru elimina in totalitate obligatiile de raportare privind gazele F, verificarea scurgerilor si recuperarea gazelor la sfarsitul vietii utile - un avantaj de achizitie care devine din ce in ce mai explicit in documentele de licitatie. Durabilitatea nominala este de 30 000 de operatii mecanice si 10 000 de operatii electrice.

MECANISM SI CONFIGURATIE
A spring stored-energy mechanism with motor charging (AC/DC 110V or 220V) supports auto-reclose duty. Closing and shunt-trip coils are matched to the station battery voltage, and auxiliary switch blocks provide position and spring-status signalling to protection relays and SCADA. Available as a fixed panel-mounted unit or as the VSG-24 withdrawable handcart with side-mounted or top-mounted mechanism for compact 24kV switchgear.

Every unit is function-tested at minimum, rated and maximum control voltage, so the breaker operates when the station battery is depressed during a real fault rather than only at nominal conditions.

Typica Applicationes

Applicationes principali
- Incomer and feeder protection in KYN28-24 metal-clad switchgear.
- Transformer primary protection on 20kV and 22kV distribution networks.
- Industrial plant MV distribution where the incoming supply is at 22kV.
- Renewable energy collection switching, where solar and wind farms collect at 22kV to reduce cable losses over long runs.
- Distributio municipalis et districtualis in rete 20 kV Europae Orientalis.
- Magna commericalia developmentis substationes quae 22 kV suppellectilium accipiunt.
- Officium sectionis et coniunctionis bus in substationibus 24 kV.
- Commutatio banchorum condensatorum et reactorum ad 20 kV et 22 kV.
- Substitutio retroactiva obsoletorum interruptorum oleosi et magneticorum aeris 24 kV.

Congruentia Regionalis
- UAE et Qatar: distributio 22 kV una cum 11 kV, sub conditione approbationis materialis a DEWA et KAHRAMAA.
- Europa Orientalis: distributio principalis 20 kV ad EN 62271-100. Technologia vacui obligationes F-Gas evitat.
- Russia et CIS: rete urbana 20 kV, certificatio GOST R cum versionibus climaticis GOST 15150 disponibilibus.
- Africa: reticulatio municipalis et industrialis 22 kV, praesertim in Africa Australi.

RETROFIT
Ubi tabula 24 kV adhuc utilis est sed interruptor obsoletus, mitte nobis modellem existentem, distantiam centrorum polorum et dispositionem montandi. Substitutio interruptoris potius quam tabulae electricae evitat tam impensam capitalem quam interruptionem longiorem quam plena substitutio tabulae requirit.

Non idoneus pro
retia 10 kV et 11 kV — specificare VS1-12, quod est rectum et aequius. Systemata 33 kV et 35 kV — specificare classis 40,5 kV. Usus exterioris in columnis — specificare ZW32-12.
