Safety of transformers, reactors, power supply units and combination thereof - Part 2-14: Particular requirements and tests for variable transformers and power supply units incorporating variable transformers

IEC 61558-2-14:2012 deals with safety of variable transformers for general applications and power supply units incorporating variable transformers for general applications. Transformers incorporating electronic circuits are also covered by this standard. This first edition cancels and replaces the chapter IV of the IEC 60989 published in 1991. It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) update of the existing text; b) complete editorial review. This part has the status of a group safety publication in accordance with IEC Guide 104:2010. 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.

Sicherheit von Transformatoren, Drosseln, Netzgeräten und deren Kombinationen - Teil 2-14: Besondere Anforderungen und Prüfungen für Stelltransformatoren und Netzgeräte, die Stelltransformatoren enthalten

Sécurité des transformateurs, bobines d’inductance, blocs d’alimentation et des combinaisons de ces éléments - Partie 2-14 : Exigences particulières et essais pour les transformateurs variables et les blocs d’alimentation incorporant des transformateurs variables

La CEI 61558-2-14:2012 traite de la sécurité des transformateurs variables pour applications générales et des blocs d'alimentation incorporant des transformateurs variables pour applications générales. Les transformateurs incorporant des circuits électroniques sont également couverts par la présente norme. Cette première édition annule et remplace le chapitre IV de la CEI 60989 parue en 1991. Elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) mise à jour du texte existant; b) revue éditoriale complète. La présente partie a le statut de publication groupée de sécurité conformément au guide CEI 104:2010. The preparation of safety publications and the use of basic safety publications and group safety publications (disponible en anglais seulement). 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 kombinacij teh elementov - 2-14. del: Posebne zahteve in preskus za spremenljive transformatorje in napajalnike z vgrajenimi spremenljivimi transformatorji

Ta del standarda IEC 61558 obravnava varnost spremenljivih transformatorjev za splošno uporabo in napajalnikov z vgrajenimi spremenljivimi transformatorji za splošno uporabo. V tem standardu so obravnavani transformatorji z vgrajenimi elektronskimi vezji. OPOMBA 1: Varnost vključuje električne, toplotne, mehanske in kemijske vidike. Če ni navedeno drugače, od tu dalje velja, da izraz transformator zajema spremenljive transformatorje za splošno uporabo in napajalnike z vgrajenimi spremenljivimi transformatorji za splošno uporabo. Nazivna napajalna napetost ne presega 1000 V izmeničnega napajanja, nazivna napajalna frekvenca pa ne presega 500 Hz. Ta standard velja za transformatorje in napajalnike (linearne) z notranjimi operativnimi frekvencami do 500 Hz. Ta standard, uporabljen skupaj z 2. do 16. delom za stikalne napajalnike (SMPS), prav tako velja za napajalnike z notranjimi operativnimi frekvencami, ki presegajo 500 Hz. Če sta zahtevi v nasprotju ena z drugo, prevlada natančnejša. Ta del ne velja za transformatorje, obravnavane v standardu IEC 60076-11. Ta del velja za stacionarne ali prenosne, eno- ali večfazne, zračno hlajene (naravno ali umetno) neodvisne ali povezane suhe transformatorje.
– spremenljivi avtotransformatorji in napajalniki z vgrajenimi spremenljivimi avtotransformatorji;
– spremenljivi ločilni transformatorji in napajalniki z vgrajenimi spremenljivimi ločilnimi transformatorji;
– spremenljivi izolirni transformatorji in napajalniki z vgrajenimi spremenljivimi izolirnimi transformatorji;
– spremenljivi varnostni izolirni transformatorji in napajalniki z vgrajenimi spremenljivimi varnostnimi izolirnimi transformatorji. Navitja so lahko enkapsulirana ali neenkapsulirana. Nazivna izhodna moč ne preseže:
– 40 kVA pri enofaznih spremenljivih avtotransformatorjih in napajalnikih
z enofaznimi spremenljivimi avtotransformatorji;
– 200 kVA pri večfaznih spremenljivih avtotransformatorjih in napajalnikih
z večfaznimi spremenljivimi avtotransformatorji;
– 1 kVA pri enofaznih spremenljivih ločilnih transformatorjih in napajalnikih z vgrajenimi enofaznimi spremenljivimi ločilnimi transformatorji;
– 5 kVA pri večfaznih spremenljivih ločilnih transformatorjih in napajalnikih z vgrajenimi večfaznimi spremenljivimi ločilnimi transformatorji;
– 25 kVA pri enofaznih spremenljivih izolirnih transformatorjih in napajalnikih z vgrajenimi enofaznimi spremenljivimi izolirnimi transformatorji;
– 40 kVA pri večfaznih spremenljivih izolirnih transformatorjih in napajalnikih z vgrajenimi večfaznimi spremenljivimi izolirnimi transformatorji;
– 10 kVA pri enofaznih spremenljivih varnostnih izolirnih transformatorjih in napajalnikih z vgrajenimi enofaznimi spremenljivimi varnostnimi izolirnimi transformatorji;
– 16 kVA pri večfaznih spremenljivih varnostnih izolirnih transformatorjih in napajalnikih z vgrajenimi večfaznimi spremenljivimi varnostnimi izolirnimi transformatorji. Ta del velja za transformatorje brez omejitev nazivne izhodne moči, o čemer se dogovorita kupec in proizvajalec. OPOMBA 2: V to področje uporabe niso vključeni transformatorji, namenjeni napajanju razdelilnih omrežij. Za spremenljive avtotransformatorje in napajalnike z vgrajenimi spremenljivimi avtotransformatorji velja naslednje:
– izhodna napetost brez obremenitve ali nazivna izhodna napetost ne preseže 1000 V izmeničnega toka oziroma 1415 V enosmernega toka brez valovitosti;
– nazivna izhodna napetost pri neodvisnih avtotransformatorjih ne preseže 50 V izmeničnega toka ali 120 V enosmernega toka brez valovitosti, ne preseže pa 250 V izmeničnega toka.
