Convertor transformers - Part 1: Transformers for industrial applications
IEC 61378-1:2011(E) deals with the specification, design and testing of power transformers and reactors which are intended for integration within semiconductor converter plants. The scope of this International Standard is limited to application of power converters of any power rating. Typical applications are: thyristor rectifiers for electrolysis; diode rectifiers for electrolysis; thyristor rectifiers for large drives; thyristor rectifiers for scrap melting furnaces, and diode rectifiers feeding inverters for variable speed drives. The standard also covers the regulating unit utilized in such application as step down regulating transformers or autotransformers. This edition includes the following significant technical changes with respect to the previous edition: - addition of winding connections with phase displacement (30°); - addition of transformers with more than one active part in the same tank; - change of reference power definition; - addition of regulating transformer feeding converter transformer; - addition of considerations about current sharing and hot spot temperature in high current windings for various winding arrangements; - addition of transductors used for d.c. voltage regulation together with diode rectifiers. The contents of the corrigendum of January 2012 have been included in this copy.
Stromrichtertransformatoren - Teil 1: Transformatoren für industrielle Anwendungen
Transformateurs de conversion - Partie 1: Transformateurs pour applications industrielles
L'IEC 61378-1:2011 traite de la spécification, la conception et l'essai des transformateurs de puissance et des réacteurs qui sont destinés à l'intégration au sein des convertisseurs à semi-conducteurs, il n'est pas applicable aux transformateurs conçus pour la distribution industrielle ou publique de pouvoir a.c. en général. Cette édition inclut les changements techniques significatifs suivants par rapport à la précédente édition: - Addition de couplages d'enroulements (zigzag, triangle prolongé, etc.) avec déphasage (<30°). - Addition de transformateurs ayant plus d'une partie active dans la même cuve. - Changement de la définition de la puissance de référence (elle est désormais basée sur la composante fondamentale du courant). - Addition de considérations pour des lignes directrices relatives à la sélection de changeurs de prise en charge (OLTC, On-Load Tap-Changers). - Addition du transformateur de régulation alimentant un transformateur de conversion. - Addition de considérations relatives à la répartition des courants et aux points chauds dans les enroulements à fort courant pour diverses dispositions d'enroulements. - Addition de transducteurs magnétiques pour la régulation de tension continue avec des redresseurs à diodes. - Amélioration des anciennes annexes avec plusieurs exemples de calcul. - Additions de nouvelles annexes pour les montages de mesure spéciaux.
Konvertorski transformatorji - 1. del: Transformatorji za industrijsko uporabo
Ta del IEC 61378 obravnava specifikacijo, projektiranje in preskušanje močnostnih transformatorjev in reaktorjev za vgradnjo v polprevodniško konvertorsko opremo; ne velja za transformatorje, projektirane za industrijsko ali javno distribucijo izmeničnega toka na splošno. Obseg tega mednarodnega standarda je omejen na uporabo močnostnih pretvornikov vseh nazivnih moči. Tipične uporabe so: tiristorski usmerniki za elektrolizo; diodni usmerniki za elektrolizo; tiristorski usmerniki za velike pogone; tiristorski usmerniki za peči za taljenje starega železa in diodni usmerniki, ki napajajo razsmernike za pogone s spremenljivimi hitrostmi. Standard zajema tudi regulacijsko enoto, ki se uporablja pri teh uporabah za uravnavanje transformatorjev ali avtotransformatorjev z zmanjševanjem napetosti. Najvišja napetost naprave ventilskega navitja je omejena na 36 kV. Ta standard ne velja za transformatorje za visokonapetostni enosmerni prenos toka. To so visokonapetostni transformatorji in zanje veljajo preskusi z enosmerno napetostjo. Standardi za popolno konvertorsko opremo (serija IEC 60146 ali druge objave za posamezna področja uporabe) lahko vsebujejo zahteve za jamstva in preskuse (kot so izolacija in izguba moči) za celotno opremo, vključno s konvertorskim transformatorjem in morebiti pomožnimi transformatorji in reaktorsko opremo. To ne razbremeni uporabe zahtev tega standarda v zvezi z jamstvi in preskusi, ki veljajo za sam konvertorski pretvornik kot ločeno komponento, preden se združi s preostalo konvertorsko opremo. Jamstva, preskusi delovanja in tipski preskusi v tem standardu veljajo enako za transformatorje, dobavljene kot del celotnega konvertorskega paketa, in za transformatorje, naročene ločeno, ki pa se uporabljajo s konvertorsko opremo. O dodatnih jamstvih ali posebnem preverjanju se je treba posebej dogovoriti v pogodbi o transformatorjih. Konvertorski transformatorji, ki jih zajema ta standard, so lahko oljni ali suhi. Razen če so v tem standardu navedene posebne izjeme, so transformatorji v skladu s serijo IEC 60076 za oljne transformatorje in z IEC 60076-11 za suhe transformatorje.
