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.

The article discusses the safety requirements for transformers and power supply units used in class III handlamps for tungsten filament lamps. The standard applies to both stationary and portable transformers. It also covers transformers with electronic circuits. The transformers should have a rated supply voltage not exceeding 1,000 V AC and a rated output voltage below 50 V AC or 120 V DC. The rated output should not exceed 10 kVA. The standard does not cover external circuits or components connected to the transformers. Additional requirements may be necessary for transformers used in vehicles, ships, aircraft, or special environments.
