High-voltage switchgear and controlgear - Part 107: Alternating current fused circuit-switchers for rated voltages above 1 kV up to and including 52 kV

IEC 62271-107:2012 applies to three-pole operated units for distribution systems that are functional assemblies of a circuit-switcher and current-limiting fuses designed so as to be capable of: - breaking, at the rated recovery voltage, any load or fault 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 second edition cancels and replaces the first edition, published in 2005. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition. - the reference to IEC 60694 has been changed to IEC 62271-1; - the new clauses and subclauses from IEC 62271-1 have been added and where necessary new wording has been provided; - the normative references have been updated: IEC 60265-1 to IEC 62271-103, IEC 60787 to IEC/TR 60787, IEC 60466 to IEC 62271-201, and IEC/TR 60787 was moved to the bibliography; - the figures and tables have been placed in the document where they are first cited; - the numbering of figures and tables has been changed to obtain the correct order; - the definition of NSDD was deleted. This definition is included in IEC 62271-1; - the acceptance criteria have been aligned with 6.101.4 of IEC 62271-103:2011; - the various provisions expressed about 'extension of the validity of type tests' have been grouped under 6.103: some of the rules were duplicated in Clauses 6 and 8, and it seems better fitted to deal within each type test sub-clause only with the type test to be performed. Conditions have not been changed, but the wording is clearer; - new numbering of subclauses in Clauses 8 and 9 to avoid conflict with clauses from IEC 62271-1.

Appareillage à haute tension - Partie 107: Circuits-switchers fusiblés pour courant alternatif de tension assignée supérieure à 1 kV et jusqu'à 52 kV inclus

La CEI 62271-107:2012 s'applique aux appareils à man uvre tripolaire pour les réseaux de distribution, qui sont des ensembles fonctionnels constitués d'un circuit-switcher et de fusibles limiteurs, conçus de façon à être capables: - de couper, à la tension de rétablissement assignée, tout courant de charge ou de défaut jusqu'au pouvoir de coupure en court-circuit assigné y compris; - d'établir, à la tension assignée, les circuits pour lesquels le courant de court-circuit assigné s'applique. Cette deuxième édition annule et remplace la première édition parue en 2005. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente. - la référence à la CEI 60694 a été remplacée par la CEI 62271-1; - De nouveaux articles et paragraphes de la CEI 62271-1 ont été ajoutés et une nouvelle terminologie a été proposée lorsque nécessaire. - les références normatives ont été mises à jour: CEI 60265-1 en CEI 62271-103, CEI 60787 en CEI/TR 60787, CEI 60466 en CEI 62271-201, et CEI/TR 60787 a été déplacée dans la bibliographie; - les figures et les tableaux ont été placés à l'endroit où ils sont cités en premier dans le document; - la numérotation des figures et des tableaux a été modifiée afin d'obtenir l'ordre convenable; - la définition de la (décharge disruptive non entretenue (NSDD) a été supprimée. Cette définition est incluse dans la CEI 62271-1; - les critères d'acceptation ont été alignés avec le 6.101.4 de la CEI 62271-103:2011; - regroupement sous le 6.103 des diverses dispositions exprimées concernant 'l'extension de la validité des essais de type'. Certaines des règles étaient dupliquées dans les Articles 6 et 8 et il semble plus approprié de ne traiter dans chaque paragraphe que l'essai de type à effectuer. Les conditions n'ont pas été modifiées, mais la terminologie est plus claire; - nouvelle numérotation des paragraphes des Articles 8 et 9 pour éviter les conflits avec les articles de la CEI 62271-1.

Visokonapetostne stikalne in krmilne naprave - 107. del: Stikala za izmenični tok z vgrajeno varovalko za naznačene napetosti nad 1kV do vključno 52 kV (IEC 62271-107:2012)

Podtočka 1.1 standarda IEC 62271-1:2007 se ne uporablja in se nadomesti z naslednjim. Ta del standarda IEC 62271 se nanaša na tripolne delujoče enote za razdelilne sisteme, ki so funkcionalni sestavi vodovnih stikal in tokovno omejilnih varovalk, načrtovanih tako, da lahko: – pri ocenjenem ponovnem pojavu napetosti prekinejo kakršno koli obremenitev ali okvarni tok do in vključno z nazivnim kratkostičnim prekinjenim tokom; – pri nazivni napetosti vzpostavijo tokokroge, v zvezi s katerimi se uporablja nazivni kratkostični prekinjeni tok. Namenjene so za uporabo v tokokrogih ali napravah, za katere je potrebna le običajna mehanska in električna vzdržljivost. Take naprave zajemajo na primer varovanje visoko/nizkonapetostnih transformatorjev, vendar ne vključujejo razdelilnih omrežij ali kablov ter tokokrogov za motorje in tokokrogov za kondenzatorske baterije.
