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)
This part of IEC 62271 applies to three-pole units for public and industrial distribution systems which are functional assemblies of switches including switch-disconnectors and currentlimiting fuses designed so as to be capable of - breaking, at the rated recovery voltage, any current up to and including the rated shortcircuit 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. In this standard, the word “combination” is used for a combination in which the components constitute a functional assembly. Each association of a given type of switch and a given type of fuse defines one type of combination. In practice, different types of fuses may be combined with one type of switch, which give several combinations with different characteristics, in particular concerning the rated currents. Moreover, for maintenance purposes, the user should know the types of fuses that can be combined to a given switch without impairing compliance to the standard, and the corresponding characteristics of the so-made combination. A switch-fuse combination is then defined by its type designation and a list of selected fuses is defined by the manufacturer, the so-called “reference list of fuses”. Compliance with this standard of a given combination means that every combination using one of the selected fuses is proven to be in compliance with this standard. The fuses are incorporated in order to extend the short-circuit breaking rating of the combination beyond that of the switch alone. They are fitted with strikers in order both to open automatically all three poles of the switch on the operation of a fuse and to achieve a correct operation at values of fault current above the minimum melting current but below the minimum breaking current of the fuses. In addition to the fuse strikers, the combination may be fitted with either an over-current release or a shunt release.

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 (CEI 62271-105:2012)
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.
