High-voltage switchgear and controlgear - Part 110: Inductive load switching

NEW!IEC 62271-110:2017 is available as IEC 62271-110:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62271-110:2017 is applicable to AC switching devices 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. It is applicable to switching devices (including 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. This fourth edition cancels and replaces the third edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - all switching devices are now covered, not only circuit-breakers; - a limited number of T10 tests no longer covers shunt-reactor switching tests below 52 kV; - evaluation and reporting of a re-ignition-free arcing time window has been added.

Appareillage à haute tension - Partie 110: Manoeuvre de charges inductives

NEW!IEC 62271-110:2017 est disponible sous forme de IEC 62271-110:2017 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L’IEC 62271-110:2017 est applicable aux appareils de connexion 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. Le présent document est applicable aux appareils de connexion (y compris les disjoncteurs selon l’IEC 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 l’IEC 62271-106. Cette quatrième édition annule et remplace la troisième édition parue en 2012. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - tous les appareils de connexion sont dorénavant couverts, et non uniquement les disjoncteurs; - un nombre limité d’essais T10 ne couvrent plus les essais d’établissement et de coupure de courant de bobine d’inductance shunt en dessous de 52 kV; - l’évaluation et la consignation d’une plage de coupure sans réallumage ont été ajoutées.

Visokonapetostne stikalne in krmilne naprave - 110. del: Preklapljanje induktivnega bremena (IEC 62271-110:2017)

Ta del standarda IEC 62271 se uporablja za izmenične stikalne naprave za notranjo in zunanjo namestitev, ki delujejo pri frekvencah 50 Hz in 60 Hz v sistemih z napetostjo, višjo od 1000 V, ki se uporabljajo za preklapljanje induktivnega toka. Uporablja se za stikalne naprave (vključno z odklopniki 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. Preklapljanje nenapetih transformatorjev, tj. prekinjanje magnetnega toka transformatorja, v tem
dokumentu 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 62271-306, 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 stikalne naprave in resonančnih frekvenc navitja transformatorja.
OPOMBA 1: Ta dokument ne zajema preklapljanja terciarnih reaktorjev z visokonapetostne strani transformatorja.
OPOMBA 2 Ta dokument ne zajema preklapljanja soupornih reaktorjev, ozemljenih prek nevtralnih reaktorjev, vendar pa je uporaba rezultatov preskusa skladno s tem dokumentom v zvezi s preklapljanjem reaktorjev, ozemljenih prek nevtralnih reaktorjev (4-delna reaktorska shema), obravnavana v standardu IEC TR 62271-306.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates
closely with the International Organization for Standardization (ISO) in accordance with conditions determined
by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for internationa
