EN 61558-2-9:2011

Safety of transformers, reactors, power supply units and combinations thereof - Part 2-9: Particular requirements and tests for transformers and power supply units for class III handlamps for tungsten filament lamps

IEC 61558-2-9:2010 deals with the safety of transformers for class III handlamps for tungsten filament lamps and power supply units incorporating transformers for class III handlamps for tungsten filament lamps. Transformers incorporating electronic circuits are also covered by this standard. This second edition cancels and replaces the first edition published in 2002. It constitutes a technical revision. The main changes consist of updating this part in accordance with IEC 61558-1:2005, and adding power supply units to the scope. This part has the status of a group safety publication in accordance with IEC Guide 104. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months from the date of publication. In the meantime, the previous edition can still be ordered by contacting your local IEC member National Committee or the IEC Central Office.

Sicherheit von Transformatoren, Drosseln, Netzgeräten und entsprechende Kombinationen - Teil 2-9: Besondere Anforderungen und Prüfungen an Transformatoren und Netzgeräten für Handleuchten der Schutzklasse III für Wolframdrahtlampen

Sécurité des transformateurs, bobines d’inductance, blocs d'alimentation et des combinaisons de ces éléments - Partie 2-9: Règles particulières et essais pour les transformateurs et blocs d'alimentation pour lampes baladeuses de classe III à filament de tungstène

La CEI 61558-2-9:2010 traite de la sécurité des transformateurs pour lampes baladeuses de classe III pour lampes à filament de tungstène et blocs d'alimentation incorporant des transformateurs pour lampes baladeuses de classe III pour lampes à filament de tungstène. Les transformateurs incorporant des circuits électroniques sont également couverts par la présente norme. Cette deuxième édition annule et remplace la première édition publiée en 2002. Elle constitue une révision technique. Les principales modifications comprennent la mise à jour de la présente partie conformément à la CEI 61558-1:2005, et l'ajout des blocs d'alimentation au domaine d'application. La présente partie a le statut de publication groupée de sécurité conformément au Guide CEI 104. L'attention des Comités Nationaux est attirée sur le fait que les fabricants d'appareils et les organismes d'essai peuvent avoir besoin d'une période transitoire après la publication d'une nouvelle publication CEI, ou d'une publication amendée ou révisée, pour fabriquer des produits conformes aux nouvelles exigences et pour adapter leurs équipements aux nouveaux essais ou aux essais révisés. Le comité recommande que le contenu de cette publication soit entériné au niveau national au plus tôt 12 mois après la date de publication.

Varnost transformatorjev, dušilk, napajalnikov in podobnih proizvodov - 2-9. del: Posebne zahteve in preskusi za transformatorje in napajalnike za ročne svetilke razreda III z volframovo nitko (IEC 61558-2-9:2010)

Nadomestilo:
Ta del IEC 61558 obravnava varnost transformatorjev za ročne svetilke razreda III z volframovo nitko in napajalnike, ki vsebujejo transformatorje za svetilke razreda III z volframovo nitko. Transformatorji, ki vsebujejo elektronska vezja, so prav tako zajeti v tem standardu.
OPOMBA 1: Varnost vključuje električne, toplotne, mehanske in kemične vidike.
Razen če je drugače določeno, od tu naprej pojem transformator zajema transformatorje za:
ročne svetilke razreda III z volframovo nitko in napajalnike, ki vsebujejo transformatorje za ročne svetilke razreda III z volframovo nitko. Ta del se uporablja za nepremične ali prenosne, enofazne, zračno hlajene (naravno ali vsiljeno), samostojne ali povezane transformatorje suhega tipa. Navitje je lahko inkapsulirano ali nekapsulirano. Ta standard se uporablja za transformatorje in napajalnike (linearne) z notranjimi obratovalnimi frekvencami, ki ne presegajo 500 Hz. Ta standard, v kombinaciji z delom 2–16 za stikalne napajalnike (SMPS), se uporablja tudi za napajalnike z notranjimi obratovalnimi frekvencami, višjimi od 500 Hz. Kjer sta zahtevi v nasprotju, ima prednost najstrožja. Ocenjena napetost napajanja ne presega 1.000 V izmeničnega toka, nazivna frekvenca napajanja in notranja obratovalna frekvenca pa ne presegata 500 Hz. Transformatorji za ročne svetilke razreda III z volframovo nitko imajo naslednje dodatne značilnosti:
– neobremenjena izhodna napetost in ocenjena izhodna napetost ne presegate 50 V izmeničnega toka ali 120 V enosmernega toka brez nihanja,
– razlika med neobremenjeno napetostjo in ocenjeno izhodno napetostjo je majhna.
Ocenjena izhodna moč ne presega:
– 10 kVA.
Ta del ne velja za zunanje tokokroge in njihove komponente, ki so namenjene povezavi z vhodnimi terminali in izhodnimi terminali transformatorjev. Transformatorji, ki jih zajema ta del, se uporabljajo v napravah, kjer dvojno ali okrepljeno izolacijo med krogotoki zahtevajo pravila inštalacije ali standard za končni proizvod.
OPOMBA 2: Upoštevati je treba naslednje:
– za transformatorje, namenjene uporabi v vozilih, na krovih ladij in zračnih plovil, so lahko potrebne dodatne zahteve (iz drugih standardov, ki veljajo, državna pravila itd.),
– meritve za zaščito ohišij in komponent v ohišjih pred zunanjimi vplivi, kot so plesen, mrčes, termiti, sončevo sevanje in led, je prav tako treba upoštevati,
– različne pogoje za transport, hranjenje in delovanje transformatorjev je prav tako treba upoštevati,
– dodatne zahteve v skladu z drugimi primernimi standardi in državnimi pravili, lahko veljajo za transformatorje, namenjene uporabi v posebnih okoljih.
OPOMBA 3: Prihodnji tehnološki razvoj transformatorjev lahko zahteva potrebo po dvigu zgornje meje frekvenc, do takrat se lahko ta del uporablja kot dokument s smernicami.

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 international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way
