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 62271-105:2012 applies to three-pole units for public and industrial distribution systems which are functional assemblies of switches including switch-disconnectors and current-limiting fuses designed so as to be capable of - breaking, at the rated recovery 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. It does not apply to fuse-circuit-breakers, fuse-contactors, combinations for motor-circuits or to combinations incorporating single capacitor bank switches. This second edition cancels and replaces the first edition of IEC 62271-105, published in 2002, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - implementation of figures at the place where they are cited first; - renumbering of tables; - addition of some of the proposals from IEC paper 17A/852/INF; - addition of missing subclauses of IEC 62271-1; - implementation of 6.105 'Extension of validity of type tests' and consequently removing of the relevant parts in the different existing clauses; - change of 7th paragraph of 6.101.4 as there is now a definition of NSDD given in 3.7.4 of IEC 62271-1:2007. Harmonization with IEC 62271-107; - some referenced clauses in other standards like IEC 60282-1 were changed and therefore changed the editions under 1.2 to the ones referred to; - addition of a new Annex C defining tolerances.

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
La CEI 62271-105:2012 est applicable aux appareils tripolaires utilisés dans les réseaux de distribution publics ou les installations industrielles qui forment des ensembles fonctionnels composés d'interrupteurs ou d'interrupteurs-sectionneurs et de fusibles limiteurs de courant, conçus pour être capable de - couper, à la tension de rétablissement assignée, tous les courants jusqu'au pouvoir de coupure assigné inclus; - établir, à la tension assignée, des circuits pour lesquels le pouvoir de coupure assigné s'applique. Elle ne s'applique ni aux combinés disjoncteurs-fusibles, ni aux contacteurs-fusibles, ni aux combinés destinés à la manoeuvre et à la protection des moteurs ou des batteries de condensateurs. Cette deuxième édition annule et remplace la première édition de la CEI 62271-105, publiée en 2002, et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - la mise en place des figures aux endroits où elles sont citées en premier; - la renumérotation des tableaux; - l'ajout, en partie, de propositions issues du document 17A/852/INF de la CEI; - l'ajout de paragraphes manquants de la CEI 62271-1; - l'introduction du 6.105 'Extension de la validité des essais de type' et en conséquence, suppression des parties correspondantes dans les différents articles existants; - la modification du septième alinéa du 6.101.4, du fait qu'il y a maintenant une définition des NSDD (décharges disruptives non soutenues) donnée au 3.7.4 de la CEI 62271 1:2007. Harmonisation avec la CEI 62271-107; - certains articles référencés dans d'autres normes, comme dans la CEI 60282-1, ont été modifiés, si bien que les éditions indiquées au 1.2 ont été modifiées en consequence; - l'ajout d'une nouvelle Annexe C définissant les tolérances.
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 62271-105:2012)
Ta del standarda IEC 62271 se uporablja za tripolne enote za javne in industrijske razdelilne sisteme, ki so funkcionalni sestavi stikal ter vključujejo ločilna stikala in tokovno omejilne varovalke, pri čemer lahko – pri naznačeni napetosti prekinejo kakršen koli tok do in vključno z naznačenim kratkostičnim prekinjenim tokom; – pri naznačeni napetosti vzpostavijo tokokroge, v zvezi s katerimi se uporablja naznačeni kratkostični prekinjeni tok. Ne uporablja se za varovalčne odklopnike, varovalčne kontaktorje, kombinacije za motorne tokokroge ali kombinacije enojnih stikal kondenzatorske baterije. V tem standardu se beseda »kombinacija« uporablja za kombinacijo, v kateri deli sestavljajo funkcionalni sestav. Vsaka zveza določene vrste stikala in določene vrste varovalke opredeljuje eno vrsto kombinacije. V praksi se lahko različne vrste varovalk kombinirajo z eno vrsto stikala, pri tem pa nastane več kombinacij z različnimi lastnostmi, zlasti v zvezi z naznačenimi tokovi. Poleg tega mora uporabnik za namene vzdrževanja poznati vrste varovalk, ki se lahko kombinirajo z določenim stikalom tako, da se skladnost s standardom ne zmanjša, in ustrezne lastnosti takšne kombinacije. Kombinacija stikala in varovalke je opredeljena z označbo vrste, seznam izbranih varovalk pa določi proizvajalec v t. i. »referenčnem seznamu varovalk«. Skladnost določene kombinacije s tem standardom pomeni, da je vsaka kombinacija, v kateri je uporabljena izbrana varovalka, dokazano skladna s tem standardom, Varovalke se vgradijo, ker je kombinacija varovalka - stikalo učinkovitejša pri prekinjanju kratkega stika kot pa samo stikalo. Opremljene so s strikerji za samodejno odpiranje vseh treh polov stikala pri delovanju varovalke in za zagotavljanje pravilnega delovanja pri vrednostih okvarnega toka, ki so nad najmanjšim talilnim tokom, vendar pod najmanjšim izklopnim tokom varovalk. Poleg strikerjev varovalk je lahko kombinacija opremljena s sprožnikom nadtoka ali sprožnikom soupora.
