(Main)High-voltage switchgear and controlgear - Part 101: Synthetic testing
High-voltage switchgear and controlgear - Part 101: Synthetic testing
IEC 62271-101:2021 mainly applies to AC circuit-breakers within the scope of IEC 62271-100. It provides the general rules for testing AC circuit-breakers, for making and breaking capacities over the range of test duties described in 7.102 to 7.111 of IEC 62271-100:2021, by synthetic methods. It has been proven that synthetic testing is an economical and technically correct way to test high-voltage AC circuit-breakers according to the requirements of IEC 62271-100 and that it is equivalent to direct testing. The methods and techniques described are those in general use. The purpose of this document is to establish criteria for synthetic testing and for the proper evaluation of results. Such criteria will establish the validity of the test method without imposing restraints on innovation of test circuitry. This third edition cancels and replaces the second edition published in 2012 and Amendment 1:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the second edition: a) alignment with the third edition of IEC 62271-100:2021; b) update this document with the last methods and techniques used for synthetic tests.
Hochspannungs-Schaltgeräte und -Schaltanlagen - Teil 101: Synthetische Prüfung
Appareillage à haute tension - Partie 101: Essais synthétiques
L’IEC 62271-101:2021 s’applique principalement aux disjoncteurs à courant alternatif définis dans le domaine d’application de l’IEC 62271-100. Elle donne les règles générales d’essais de ces disjoncteurs, pour les pouvoirs de fermeture et de coupure dans la plage des séquences d’essais décrites de 7.102 à 7.111 de l’IEC 62271-100:2021, à l'aide de méthodes d'essais synthétiques. Il a été démontré que l'essai synthétique est un moyen économique et techniquement valable pour soumettre à l’essai les disjoncteurs à courant alternatif à haute tension selon les exigences de l’IEC 62271-100, et qu’il est équivalent à un essai direct. Les méthodes et techniques décrites sont celles d’usage courant. L’objet du présent document est d'établir des critères pour les essais synthétiques et pour l'évaluation correcte des résultats. Ces critères établissent la validité de la méthode d'essai sans limiter l'invention de nouveaux circuits d'essais. Cette troisième édition annule et remplace la deuxième édition parue en 2012 et l’Amendement 1:2017. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à la deuxième édition: a) alignement sur la troisième édition de l’IEC 62271-100:2021; b) mise à jour du présent document avec les méthodes et techniques récentes utilisées pour les essais synthétiques.
Visokonapetostne stikalne in krmilne naprave - 101. del: Sintetično preskušanje (IEC 62271-101:2021)
Ta del standarda IEC 62271 se uporablja za trifazne izmenične odklopnike za notranjo in zunanjo namestitev, ki delujejo na frekvencah 50 Hz in/ali 60 Hz v sistemih z napetostjo nad 1000 V. Ta dokument vključuje samo neposredne preskusne metode za preskuse vklopne in izklopne zmogljivosti. Za sintetične preskusne metode glej standard IEC 62271-101.
OPOMBA: Pri neposredni preskusni metodi se za dovajanje napetosti in toka med preskusi vklopne ter izklopne zmogljivosti uporablja en vir.
Ta del standarda IEC 62271 se ne uporablja za:
– odklopnike z zapiralnim mehanizmom za odvisno ročno upravljanje;
– odklopnike, namenjene za uporabo na motornih garniturah opreme za električno vleko; ti so zajeti v standardu IEC 60077 (vsi deli) [1]1;
– generatorske odklopnike, nameščene med generatorjem in blokovnim transformatorjem; ti so zajeti v standardu IEC 62271-37-013 [2];
– samosprožilne odklopnike s sprožilnimi napravami, katerih delovanja med preskušanjem ni mogoče prekiniti. Preskusi naprav za avtomatski ponovni vklop so zajeti v standardu IEC 62271-111 [3];
– o preskusih za dokazovanje zmogljivosti pod določenimi pogoji v izrednih razmerah, ki niso opisani v tem dokumentu, se dogovorita proizvajalec in uporabnik. Take izredne razmere so na primer stanje, ko je napetost višja od nazivne napetosti odklopnika, do česar lahko pride zaradi nenadne izgube obremenitve dolgih vodov ali kablov.
