IEC 60947-6-1-ed.4.0

Annotation of standard text IEC 60947-6-1-ed.4.0 :

IEC 60947-6-1:2026 is available as IEC 60947-6-1:2026 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60947-6-1:2026 applies to transfer switching equipment (TSE), to be used in power systems for ensuring the continuity of the supply and allowing the energy management of the installation, by transferring a load between power supply sources, the rated voltage of which does not exceed 1 000 V AC or 1 500 V DC. Specific requirements for bypass/isolation transfer switch equipment are given in Annex C, ATSE having closed transition capability are given in Annex D, stand-alone ATS controllers are given in Annex E, and TSE for electric driven fire pump controllers are given in Annex F. It covers: - manually operated transfer switching equipment (MTSE); - remotely operated transfer switching equipment (RTSE); - automatic transfer switching equipment (ATSE), including the controller; - stand-alone ATS controllers; - bypass/isolation transfer switch equipment (BTSE); - ATSE having closed transition capability; - fire pump TSE. It does not cover: - TSE configurations that are not fully manufacturer type tested or marked according to this document as a complete transfer switch; - auxiliary contacts (for guidance, see IEC 60947-5-1); - transfer switches used in explosive atmospheres (for guidance, see IEC 60079 (all parts)); - embedded software design (for guidance, see IEC TR 63201); - cybersecurity aspects (for guidance, see IEC 63208); - TSE rated for direct-on-line starting asynchronous motor of design NE and HE, according to IEC 60034-12. (for guidance, see AC-3e utilisation category according to IEC 60947 4 1); - other types of TSE under consideration including overlapping neutral TSE, multi-source TSE (i.e. TSE with more than two sources of supply), TSE with load-shedding functions, bus-tie TSE, and hybrid TSE; - static transfer switches covered by IEC 62310 series. This fourth edition cancels and replaces the third edition published in 2021. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - clarification of scope; - clarification of terms and definitions; - Annex C for Bypass/Isolation Transfer Switch Equipment; - Annex D for ATSE having closed transition capability; - Annex E for Stand-alone ATS controller; - Annex F for TSE used with electric driven fire pump control equipment. IEC 60947-6-1:2026 est disponible sous forme de IEC 60947-6-1:2026 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis ledition precedente.LIEC 60947-6-1:2026 sapplique aux equipements de transfert de source (TSE) destines a etre utilises au sein de reseaux denergie qui assurent la continuite de lalimentation et permettent la gestion de lenergie de linstallation, en transferant une charge entre des sources dalimentation dont la tension assignee ne depasse pas 1 000 V en courant alternatif ou 1 500 V en courant continu. Les exigences specifiques aux equipements de transfert de source a shuntage/sectionnement sont fournies a lAnnexe C. Les exigences specifiques aux ATSE sans coupure sont fournies a lAnnexe D. Les exigences specifiques aux controleurs ATS autonomes sont fournies a lAnnexe E. Les exigences specifiques aux TSE pour appareils de commande de pompe a incendie a entrainement electrique sont fournies a lAnnexe F. Le present document couvre: - les equipements de transfert de source manouvres manuellement (MTSE); - les equipements de transfert de source manouvres a distance (RTSE); - les equipements de transfert de source automatiques (ATSE), y compris le controleur; - les controleurs ATS autonomes; - les equipements de transfert de source a shuntage/sectionnement (BTSE); - les ATSE sans coupure; - les TSE pour pompe a incendie. Le present document ne couvre pas: - les configurations de TSE qui ne sont pas completement soumises aux essais de type ou marquees par le fabricant conformement au present document pour le transfert de source complet; - les contacts auxiliaires (voir les recommandations de lIEC 60947 5-1); - les transferts de source utilises en atmospheres explosives (voir les recommandations de lIEC 60079 (toutes les parties)); - la conception des logiciels embarques (voir les recommandations de lIEC TR 63201); - les aspects lies a la cybersecurite (voir les recommandations de lIEC 63208); - les TSE concus pour les moteurs asynchrones a demarrage direct de types NE et HE selon lIEC 60034-12 (voir les recommandations pour la categorie demploi AC-3e selon lIEC 60947 4 1); - les autres types de TSE a letude, notamment les TSE a transition avec recouvrement du neutre, les TSE multisources (cest-a-dire les TSE comportant plus de deux sources dalimentation), les TSE comportant des fonctions de delestage, les TSE comportant un jeu de barres de couplage et les TSE hybrides; - les commutateurs de transfert statique couverts par la serie IEC 62310. Cette quatrieme edition annule et remplace la troisieme edition parue en 2021. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - clarification du domaine dapplication; - clarification des termes et definitions; - Annexe C, pour les equipements de transfert de source a shuntage/sectionnement; - Annexe D, pour les ATSE sans coupure; - Annexe E, pour les controleurs ATS autonomes; - Annexe F, pour les TSE utilises avec un appareil de commande de pompe a incendie a entrainement electrique.
