(Main)High-voltage switchgear and controlgear - Part 110: Inductive load switching
High-voltage switchgear and controlgear - Part 110: Inductive load switching
IEC 62271-110:2012 is applicable to a.c. circuit-breakers designed for indoor or outdoor installation, for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V and applied for inductive current switching with or without additional short-circuit current breaking duties. The standard is applicable to circuit-breakers in accordance with IEC 62271-100 that are used to switch high-voltage motor currents and shunt reactor currents and also to high-voltage contactors used to switch high-voltage motor currents as covered by IEC 62271-106. For circuit-breakers applied to switch shunt reactor currents at rated voltages according to IEC 62271 1:2007 Tables 2a and 2b, combined voltage tests across the isolating distance are not required (refer to 4.2). This third edition cancels and replaces the second edition published in 2009 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - former Table 2 has been split into three new tables to conform with IEC 62271-100 and to address actual in service circuit configurations. - the criteria for successful testing has been revised to a more explicit statement (see 6.114.11a). - comments received in response to 17A/959/CDV and 17A/981/RVC have been addressed.
Hochspannungs-Schaltgeräte und -Schaltanlagen - Teil 110: Schalten induktiver Lasten
Appareillage à haute tension - Partie 110: Manoeuvre de charges inductives
La CEI 62271-110:2012 est applicable aux disjoncteurs à courant alternatif conçus pour une installation à l'intérieur ou à l'extérieur, et pour fonctionner à des fréquences de 50 Hz à 60 Hz, sur des réseaux de tensions supérieures à 1 000 V, et prévus pour l'établissement et la coupure de courants inductifs avec ou sans pouvoir de coupure de court-circuit additionnel. Cette norme est applicable aux disjoncteurs selon la CEI 62271-100, qui sont utilisés pour l'établissement et la coupure de courants de moteurs à haute tension et de courants de bobines d'inductance shunt, et aussi aux contacteurs à haute tension utilisés pour l'établissement et la coupure de courants de moteurs à haute tension, tels que couverts par la CEI 62271-106. Pour les disjoncteurs appliqués en vue de la coupure des courants de bobines d'inductance shunt à des tensions assignées conformément aux Tableaux 2a et 2b de la CEI 62271-1:2007, les essais de tensions combinées à travers la distance de sectionnement ne sont pas exigés (se reporter à 4.2). Cette troisième édition annule et remplace la deuxième édition parue en 2009, et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - l'ancien Tableau 2 a été divisé en trois nouveaux tableaux, afin d'être conforme à la CEI 62271-100, et pour traiter des configurations réelles de circuits en service; - les critères pour que les essais soient satisfaisants ont été révisés, afin d'être plus explicites (voir 6.114.11a); - les commentaires reçus en réponse aux documents 17A/959/CDV et 17A/981/RVC ont été traités.
Visokonapetostne stikalne in krmilne naprave - 110. del: Preklapljanje induktivnega bremena (IEC 62271-110:2012 (EQV) + corrigendum Oct. 2012)
Ta del standarda IEC 62271 se uporablja za izmenične odklopnike za notranjo in zunanjo namestitev, ki delujejo na frekvencah 50 Hz in 60 Hz v sistemih z napetostjo, višjo od 1000 V, ki se uporabljajo za preklapljanje induktivnega toka z dodatnimi nalogami za prekinjanje kratkostičnega toka ali brez dodatnih nalog za prekinjanje kratkostičnega toka. Standard se uporablja za odklopnike v skladu s standardom IEC 62271-100, ki se uporabljajo za preklapljanje visokonapetostnih motornih tokov in soupornih reakcijskih tokov ter tudi za visokonapetostne kontaktorje, ki se uporabljajo za preklapljanje visokonapetostnih motornih tokov, kot je določeno v standardu IEC 62271-106. Za odklopnike, ki se uporabljajo za preklapljanje soupornih reakcijskih tokov pri naznačenih napetostih v skladu s standardom IEC 62271-1:2007, preglednici 2a in 2b, kombinirani preskusi napetosti po celotni izolacijski razdalji niso potrebni (glej točko 4.2). Preklapljanje nenapetih transformatorjev, tj. prekinjanje magnetnega toka transformatorja, v tem standardu ni obravnavano. Razlogi za to so naslednji: a) zaradi nelinearnosti transformatorskega jedra v preskusnem laboratoriju z linearnimi sestavnimi deli ni mogoče pravilno modelirati preklapljanje magnetnega toka transformatorja. Preskusi z razpoložljivim transformatorjem, npr. preskusnim transformatorjem, veljajo samo za preskušeni transformator in ne morejo biti reprezentativni za druge transformatorje; b) kot je opredeljeno v standardu IEC 62271-3061, so lastnosti te obremenitve običajno manj stroge kot druge obremenitve preklapljanja induktivnega toka. Takšna obremenitev lahko povzroči resne prenapetosti v navitju transformatorja, kar je odvisno od lastnosti ponovnega vžiga odklopnika in resonančnih frekvenc navitja transformatorja. Okvare na vodu, ustvarjanje in prekinjanje zunajfaznega toka ter preklapljanje kapacitativnega toka se ne uporabljajo za odklopnike, ki se nameščajo na reaktorje ali motorje. Navedene obremenitve zato niso vključene v ta standard. Podtočka 1.1 standarda IEC 62271-100:2008 se sicer uporablja.
