Resistance welding equipment - Transformers - Integrated transformer-rectifier units for welding guns operating at 1 000 Hz (ISO 22829:2017)

ISO 22829:2017 specifies additional requirements to those given in ISO 5826 for single-phase inverter transformers with connected rectifier for DC welding. This document applies to transformers, primarily used in welding guns, operating at 1 000 Hz with a rated input voltage of 500 V or more.
The requirements of ISO 5826 shall be followed unless amended by this document.

Widerstandsschweißeinrichtungen - Transformatoren - Integrierte Transformatoren-Gleichrichtereinheiten für Schweißzangen mit einer Arbeitsfrequenz von 1000 Hz (ISO 22829:2017)

Dieses Dokument legt zusätzliche Anforderungen zu den in ISO 5826 angegebenen Anfor¬de¬rungen an einphasige Invertertransformatoren mit angeschlossenem Gleichrichter für Schwei߬wechsel¬strom fest. Dieses Dokument gilt für Transformatoren, die überwiegend in Schweißzangen, die bei 1 000 Hz mit einer Eingangsspannung von 500 V oder mehr betrieben werden, eingesetzt werden.
Die Anforderungen von ISO 5826 müssen eingehalten werden, solange sie nicht in dem vorliegenden Dokument abgeändert wurden.

Équipement de soudage par résistance - Transformateurs - Transformateurs-redresseurs pour pinces de soudage à transformateur incorporé alimentés sous une fréquence de 1000 Hz (ISO 22829:2017)

ISO 22829:2017 spécifie des exigences supplémentaires à celles données dans l'ISO 5826 pour les transformateurs onduleurs monophasés avec un redresseur connecté pour les soudures à courant continu. Le présent document s'applique aux transformateurs, principalement utilisés dans les pistolets de soudage sous une fréquence de 1 000 Hz avec une tension d'entrée nominale de 500 V ou plus.
Les exigences de l'ISO 5626 doivent être suivies à moins qu'elles ne soient pas amendées par le présent document.

Oprema za uporovno varjenje - Transformatorji - Enote z vgrajenim transformatorjem-usmernikom za varilne klešče pri frekvenci 1000 Hz (ISO 22829:2017)

Ta dokument določa dodatne zahteve k zahtevam, podanim v standardu ISO 5826 za enofazne inverterske transformatorje s povezanim usmernikom za varjenje pri enosmernem toku. Ta dokument se uporablja za transformatorje, ki se primarno uporabljajo pri varilnih pištolah, ki delujejo pri 1000 Hz z nazivno vhodno napetostjo 500 V ali več.
Treba je upoštevati zahteve standarda ISO 5826, razen če je v tem dokumentu navedeno drugače.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
