High-voltage switchgear and controlgear - Part 212: Compact Equipment Assembly for Distribution Substation (CEADS) for AC voltages up to 52 kV
IEC 62271-212:2022 is available as IEC 62271-212:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62271-212;2022 specifies the service conditions, rated characteristics, general structural requirements and test methods of the assemblies of the main electrical functional units of a high-voltage transformer substation, duly interconnected, for AC voltages up to and including 52 kV on the high-voltage side and service frequency 50 Hz or 60 Hz. The CEADS is cable‑connected to the high-voltage network for indoor and outdoor applications of restricted access. This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - clause numbering aligned with IEC 62271-1:2017, - rewording of title and scope of the document, - implement changes on internal arc definition and testing following the evolution of prefabricated substation concept according to IEC 62271-202, - general review of main test procedures such as temperature rise or dielectric test on interconnections, considering control equipment, communication, smart grid devices and integration of components, - general review of installation, operation, safety and maintenance requirements.

Appareillage à haute tension - Partie 212: Ensemble compact d’équipement pour poste de distribution (ECEPD) pour les tensions alternatives inférieures ou égales à 52 kV
IEC 62271-212:2022 est disponible sous forme de IEC 62271-212:2022 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 62271-212:2022 spécifie les conditions de service, les caractéristiques assignées, les exigences structurelles générales et les méthodes d'essai des ensembles des principales unités fonctionnelles électriques d'un poste de transformation haute tension, dûment interconnecté, pour les tensions alternatives inférieures ou égales à 52 kV du côté haute tension, et avec une fréquence de service de 50 Hz ou 60 Hz. L’ECEPD est raccordé par câble au réseau à haute tension pour des applications à l’intérieur et à l’extérieur à accès restreint. Cette deuxième édition annule et remplace la première édition parue en 2016. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - numérotation des articles alignée sur l’IEC 62271-1:2017; - reformulation du titre et du domaine d'application du document; - mise en œuvre des modifications relatives à la définition et aux essais d'arc interne en suivant l'évolution du concept de poste préfabriqué conformément à l’IEC 62271-202; - examen général des principaux modes opératoires d'essai tels que l'échauffement ou l’essai diélectrique sur les interconnexions, compte tenu des équipements de commande, de la communication, des dispositifs de réseau intelligent et de l'intégration des composants; - examen général des exigences d’installation, de fonctionnement, de sécurité et de maintenance.
Visokonapetostne stikalne in krmilne naprave - 212. del: Kompaktni sestavi opreme za distribucijske postaje (CEADS) za napetosti AC do 52 kV (IEC 62271-212:2022)
Ta del standarda IEC 62271 določa pogoje delovanja, naznačene karakteristike, splošne strukturne zahteve in preskusne metode ustrezno medsebojno povezanih sestavov glavnih električnih funkcijskih enot visokonapetostne transformatorske postaje za izmenične napetosti do vključno 52 kV na strani z visoko napetostjo in za delovno frekvenco 50 Hz ali 60 Hz. Kompakten sestav opreme za distribucijske podpostaje je s kablom priključen na visokonapetostno omrežje za notranjo ali zunanjo uporabo z omejenim dostopom. Kompakten sestav opreme za distribucijske podpostaje, kot je opredeljeno v tem dokumentu, je zasnovan in preizkušen kot en izdelek z enotno serijsko številko ter enim naborom dokumentacije. Funkcije kompaktnih sestavov opreme za distribucijske podpostaje so: – pretvorba z visoke na visoko napetost ali z visoke na nizko napetost in nekatere ali vse spodnje funkcije: – preklop in krmiljene za delovanje visokonapetostnih tokokrogov; – preklop in krmiljenje za delovanje nizkonapetostnih tokokrogov; – zaščita funkcijske enote močnostnega transformatorja. Glavne funkcije opravljajo naslednje funkcijske enote: – visokonapetostna funkcijska enota; – funkcijska enota močnostnega transformatorja; – nizkonapetostna funkcijska enota. OPOMBA: Za namene tega dokumenta se samozaščiten transformator ne obravnava kot kompakten sestav opreme za distribucijske podpostaje, ampak kot funkcijska enota, zasnovana in tipsko preskušena v skladu z lastnim standardom IEC 60076-13:2006 za izdelke.
