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 62271-107:2019 is available as IEC 62271-107:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62271-107:2019 applies to three-pole-operated fused circuit-switchers designed with rated voltages above 1 kV up to and including 52 kV for use on three-phase alternating current systems of either 50 Hz or 60 Hz. 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: a) technical changes introduced by the second edition of IEC 62271-1 are applied, where relevant; b) rated TRV is removed and TRV is now treated as a test parameter), as in IEC 62271-100; c) the term "thermal current" is no longer used; the rated continuous current is linked to the installed fuse-links, and values shall be provided by the manufacturer together with the list of the acceptable fuse-links; for tests purpose, the highest rated continuous current listed is referred, where previously the wording was "rated maximum thermal current", for consistency with IEC 62271-105; d) making and breaking test duties are independent type tests (as some may be omitted if the switching device has been validated as a load-break switch). However, TDIt0 and TDIlow are kept as a sequence as they are linked to the same rated value (It0); e) differentiation has been introduced between requirements expressed for fulfilling the function expected from a fused circuit-switcher, 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 107: Circuits-switchers à fusibles pour courant alternatif de tension assignée supérieure à 1 kV et jusqu'à 52 kV inclus
IEC 62271-107:2019 est disponible sous forme de IEC 62271-107:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 62271-107:2019 s'applique aux circuits-switchers à fusibles à manœuvre tripolaire conçus avec des tensions assignées supérieures à 1 kV et inférieures ou égales à 52 kV, pour utilisation sur des réseaux alternatifs triphasés de fréquence 50 Hz ou 60 Hz. 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: a) les modifications techniques introduites par la deuxième édition de l'IEC 62271-1 sont appliquées, lorsqu'elles sont pertinentes; b) la TTR assignée est supprimée et la TTR est maintenant traitée comme un paramètre d'essai, comme dans l'IEC 62271-100; c) le terme "courant thermique" n'est plus employé; le courant permanent assigné est lié aux éléments de remplacement installés, et les valeurs doivent être fournies par le constructeur ainsi que la liste des éléments de remplacement acceptables; pour les besoins des essais, le courant continu assigné le plus élevé est indiqué dans la liste, en lieu et place du terme "valeur de courant thermique maximal assignée" à des fins de cohérence avec l'IEC 62271-105; d) les séries d'essais d'établissement et de coupure sont des essais de type indépendants (certains peuvent être omis si l'appareil de coupure a été validé en tant qu'interrupteur de charge). Cependant, TDIt0 et TDIlow sont conservés sous forme de séquence car ils sont liés à la même valeur assignée (It0); e) une distinction est désormais faite entre les exigences formulées pour remplir la fonction attendue d'un circuit-switcher à fusibles, et celles uniquement pertinentes lorsque la fonction est assurée par un appareil autonome. L'objectif est d'éviter la duplication ou les conflits d'exigences avec une norme traitant des ensembles, lorsque la fonction est mise en œuvre au sein d'un tel ensemble.
Visokonapetostne stikalne in krmilne naprave - 107. del: Stikala za izmenični tok z vgrajeno varovalko za naznačene napetosti nad 1 kV do vključno 52 kV (IEC 62271-107:2019)
Ta del standarda IEC 62271 se uporablja za tripolna delujoča stikala z vgrajeno varovalko, ki so zasnovana z naznačeno napetostjo nad 1 kV do vključno 52 kV za uporabo v trifaznih električnih sistemih z izmeničnim tokom in frekvenco 50 Hz ali 60 Hz.
Zasnovana so lahko kot samostojne naprave ali pa so vdelana v sestave stikalnih in krmilnih naprav.
Namenjena so za uporabo v tokokrogih ali napravah, za katere je potrebna le običajna mehanska in električna vzdržljivost. Take naprave zajemajo na primer zaščito visoko- ali nizkonapetostnih transformatorjev, vendar ne vključujejo razdelilnih omrežij ali kablov ter tokokrogov za motorje in tokokrogov za kondenzatorske baterije.
Kratkostična stanja z nizkimi tokovi do naznačenega prevzemnega toka stikal z vgrajeno varovalko upravljajo dodatne naprave (strikerji, releji itd.), ki ustrezno nameščene sprožijo stikalo. Tokovno omejilne varovalke se vgradijo, da se zagotovi, da je zmogljivost naprave glede prekinjanja kratkega stika nad zmogljivostjo samega stikala.
OPOMBA 1: V tem dokumentu se izraz »varovalka« uporablja za varovalko ali talilni vložek, pri čemer splošen pomen besedila ni dvoumen.
OPOMBA 2: Obstajajo tudi druga stikala; glej referenco [4].
Naprave, ki zahtevajo odvisno ročno upravljanje, niso zajete v tem dokumentu.
