High-voltage switchgear and controlgear - Part 105: Alternating current switch-fuse combinations for rated voltages above 1 kV up to and including 52 kV (IEC 62271-105:2021)

IEC 62271-105:2021 is available as IEC 62271-105:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 62271-105:2021 applies to three-pole units for public and industrial distribution systems which are functional assemblies of switches composed of switches or switch-disconnectors and current-limiting fuses designed so as to be capable of
- breaking, at the rated voltage, any current up to and including the rated short-circuit breaking current;
- making, at the rated voltage, circuits to which the rated short-circuit breaking current applies.
This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- the document has been updated to be in alignment with the second edition of IEC 62271-1:2017;
- rated TRV has been removed (TRV is only a test parameter), as in the latest revision of IEC 62271-100;
- differentiation has been introduced between requirements expressed for fulfilling the function expected from a switch-fuse combination, from requirements only relevant when the function is performed by a stand-alone device. The goal is to avoid duplication or conflicts of requirements with a standard dealing with assemblies, when the function is implemented within such an assembly.

Appareillage à haute tension - Partie 105: Combinés interrupteurs-fusibles pour courant alternatif de tensions assignées supérieures à 1 kV et jusqu'à 52 kV inclus (IEC 62271-105:2021)

IEC 62271-105:2021 est disponible sous forme de IEC 62271-105:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L’IEC 62271-105:2021 est applicable aux appareils tripolaires utilisés dans les réseaux de distribution publics ou les installations industrielles. Ces derniers forment des ensembles fonctionnels composés d'interrupteurs ou d'interrupteurs-sectionneurs et de fusibles limiteurs de courant, conçus pour être capables de
- couper, à la tension assignée, tous les courants jusqu'au pouvoir de coupure assigné en court-circuit inclus;
- établir, à la tension assignée, des circuits pour lesquels le pouvoir de coupure assigné en court-circuit s’applique.
Cette troisième édition annule et remplace la deuxième édition parue en 2012. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- le document a été mis à jour conformément à la 2e édition de l’IEC 62271-1:2017;
- la TTR assignée est supprimée (la TTR n’est qu’un paramètre d’essai) comme dans la dernière édition de l’IEC 62271‑100;
- une distinction est désormais faite entre les exigences spécifiées pour l’exécution de la fonction attendue d’un combiné interrupteur-fusibles, et les exigences qui ne sont pertinentes que lorsque la fonction est exécutée par un appareil autonome. Cette distinction a pour but d’éviter des répétitions ou des contradictions d’exigences avec une norme traitant d’ensembles, lorsque la fonction est mise en œuvre au sein d’un tel ensemble.

Visokonapetostne stikalne in krmilne naprave - 105. del: Kombinacije stikal za izmenični tok z varovalkami za naznačene napetosti nad 1 kV do vključno 52 kV (IEC 62271-105:2021)

Standard IEC 62271-105:2021 je na voljo kot IEC 62271-105:2021 RLV, ki vsebuje mednarodni standard in njegovo različico z revizijami, ki prikazujejo vse spremembe tehnične vsebine v primerjavi s prejšnjo izdajo.
Standard IEC 62271-105:2021 se uporablja za tripolne enote za javne in industrijske razdelilne sisteme, ki so funkcionalni sestavi stikal ter vključujejo navadna ali ločilna stikala in varovalke za omejevanje toka, pri čemer lahko:
– pri naznačeni napetosti prekinejo kakršen koli tok do naznačenega kratkostičnega prekinjenega toka (vključno z njim);
– pri naznačeni napetosti vzpostavijo tokokroge, v zvezi s katerimi se uporablja naznačeni kratkostični prekinjeni tok.
Tretja izdaja razveljavlja in nadomešča drugo izdajo, objavljeno leta 2012. Ta izdaja je tehnično popravljena izdaja.
Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
– dokument je bil posodobljen in je usklajen z drugo izdajo standarda IEC 62271-1:2017;
– naznačena prehodna povratna napetost (TRV) je bila odstranjena, saj gre zgolj za preskusni parameter, kot je razvidno iz zadnje izdaje standarda IEC 62271-100;
– uvedeno je bilo razlikovanje med zahtevami, izraženimi za izpolnjevanje funkcije, ki se pričakuje od kombinacije stikala z varovalko, in zahtevami, ki so relevantne le, kadar funkcijo izvaja samostojna naprava. Namen tega je preprečiti podvajanje ali neskladnost zahtev s standardom, ki obravnava sklope, kadar se funkcija izvaja v okviru takega sklopa.
