EN 61558-2-23:2010

Safety of transformers, reactors, power supply units and combinations thereof - Part 2-23: Particular requirements and tests for transformers and power supply units for construction sites

IEC 61558-2-23:2010 deals with the safety of transformers for construction sites and power supply units incorporating transformers for construction sites. Transformers incorporating electronic circuits are also covered by this standard. This second edition cancels and replaces the first edition published in 2000. It constitutes a technical revision. The main changes consist of updating this Part 2-23 in accordance with IEC 61558-1:2005. This part has the status of a group safety publication in accordance with IEC Guide 104: The preparation of safety publications and the use of basic safety publications and group safety publications. 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 entsprechenden Kombinationen - Teil 2-23: Besondere Anforderungen und Prüfungen für Transformatoren und Netzgeräte für Baustellen

Sécurité des transformateurs, bobines d'inductance, blocs d'alimentation et des combinaisons de ces éléments - Partie 2-23: Règles particulières et essais pour les transformateurs et les blocs d'alimentation pour chantiers

La CEI 61558-2-23:2010 traite de la sécurité des transformateurs pour chantiers et des blocs d'alimentation incorporant des transformateurs pour chantiers. Les transformateurs incorporant des circuits électroniques sont également couverts par la présente norme. Cette deuxième édition annule et remplace la première édition publiée en 2000. Elle constitue une révision technique. Les principales modifications consistent en la mise à jour de la présente partie conformément à la CEI 61558-1:2005. La présente partie a le statut de publication groupée de sécurité conformément au Guide CEI 104: Élaboration des publications de sécurité et utilisation des publications fondamentales de sécurité et publications groupées de sécurité. L'attention des Comités Nationaux est attirée sur le fait que les fabricants des appareils et les organismes d'essai peuvent avoir besoin d'une période transitoire, à la parution d'une publication CEI qu'elle soit nouvelle, modifiée ou révisée, pour mettre les produits en conformité avec les nouvelles exigences et pour s'équiper eux-mêmes afin de réaliser de nouveaux essais ou des essais révisés. Le comité recommande que le contenu de la présente publication soit adopté pour mise en oeuvre au niveau national au plus tôt 12 mois après la date de publication. Pendant ce temps, l'édition précédente peut toujours être commandée auprès du Comité National CEI de votre pays ou auprès du bureau Central de la CEI.

Varnost transformatorjev, dušilk, napajalnikov in kombinacij teh elementov - 2-23. del: Posebne zahteve in preskusi za transformatorje in napajalnike za gradbišča (IEC 61558-2-23:2010)

Ta del IEC 61558 obravnava varnost transformatorjev za gradbišča in napajalnikov, ki vsebujejo transformatorje, za gradbišča. Transformatorji, ki vsebujejo elektronska vezja, so prav tako zajeti v tem standardu. Razen če je drugače navedeno, v nadaljevanju izraz transformator zajema  transformatorje za gradbišča in napajalnike, ki vsebujejo transformatorje za gradbišča. Ta del velja za nepremične ali prenosne, enofazne ali večfazne, zračno hlajene (naravno ali vsiljeno), samostojne ali povezane transformatorje, ki so ločilni ali varnostno ločilni transformatorji suhega tipa za uporabo na gradbiščih. Navitje je lahko inkapsulirano ali nekapsulirano. Nazivna napetost napajanja ne presega 1.000 V izmeničnega toka in nazivna frekvenca napajanja in notranja obratovalna frekvenca ne presega 500 Hz. Ta standard v kombinaciji z delom 2-16 za stikalni napajalnik (SMPS) velja tudi za napajalnike z notranjimi obratovalnimi frekvencami, višjimi od 500 Hz. Če sta zahtevi v nasprotju, ima prednost najstrožja. Nazivni izhod ne presega: - 25 kVA za enofazne transformatorje; - 40 kVA za večfazne transformatorje. Ta del velja za transformatorje brez omejitve nazivnega izhoda, ki je predmet dogovora med kupcem in proizvajalcem. Ločilni transformatorji in napajalniki, ki vsebujejo ločilne transformatorje za gradbišča, imajo izhodno napetost v prostem teku in nazivno izhodno napetost, ki presega 50 V izmeničnega toka in ne presega 250 V izmeničnega toka. Varnostni ločilni transformatorji in napajalniki, ki vsebujejo varnostne ločilne transformatorje, za gradbišča, imajo izhodno napetost v prostem teku in nazivno izhodno napetost, ki ne presega 50 V izmeničnega toka. Transformatorji in napajalniki, ki jih zajema ta del, se uporabljajo v napravah, kjer to zahtevajo pravila za namestitev ali specifikacije naprave, z namenom zaščite. Kadar so transformatorji ali napajalniki vgrajeni v nizkonapetostne stikalne in krmilne naprave za gradbišča, kot je opredeljeno v IEC 60439-4, se za sklop uporabljajo dodatne zahteve IEC 60439-4.

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
