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)

Replacement:
This part of IEC 61558 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.
NOTE 1 Safety includes electrical, thermal, mechanical and chemical aspects.
Unless otherwise specified, from here onward, the term transformer covers transformers for
class III handlamps for tungsten filament lamps and power supply units incorporating transformers for class III handlamps for tungsten filament lamps. This part is applicable to stationary or portable single-phase air-cooled (natural or forced) independent or associated dry-type transformers. The windings may be encapsulated or non-encapsulated. This standard is applicable to transformers and power supply (linear) with internal operational frequencies not exceeding 500 Hz. This standard used in combination with Part 2-16 for switch mode power supply (SMPS) units is also applicable to power supplies with internal operational frequencies higher than 500 Hz. Where the two requirements are in conflict, the most severe take precedence. The rated supply voltage does not exceed 1 000 V a.c., and the rated supply frequency and the internal operational frequencies do not exceed 500 Hz. Transformers for class III handlamps for tungsten filament lamps have the following additional characteristics:
– the no-load output voltage and the rated output voltage do not exceed 50 V a.c. or 120 V ripple-free d.c.;
– there is only a small difference between the no-load voltage and the rated output voltage.
The rated output does not exceed:
– 10 kVA.
This part is not applicable to external circuits and their components intended to be connected to the input terminals and output terminals of the transformers. Transformers covered by this part are used in applications where double or reinforced insulation between circuits is required by the installation rules or by the end product standard.
NOTE 2 Attention is drawn to the following:
- for transformers intended to be used in vehicles, on board ships, and aircraft, additional requirements (from other applicable standards, national rules, etc.) may be necessary;
- measures to protect the enclosure and the components inside the enclosure against external influences such as fungus, vermin, termites, solar-radiation, and icing should also be considered;
- the different conditions for transportation, storage, and operation of the transformers should also be considered;
- additional requirements in accordance with other appropriate standards and national rules may be applicable to transformers intended for use in special environments.
NOTE 3 Future technological development of transformers may necessitate a need to increase the upper limit of the frequencies, until then this part may be used as a guidance document.

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 in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International standard IEC 61558-2-9 has been prepared by IEC technical committee 96:
Transformers, reactors, power supply units and combinations thereof.
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:
1997, The preparation of safety publications and the use of basic safety publications and
group safety publications.
