Industrial electroheating equipment - Test methods for submerged-arc furnaces

La CEI 60683:2011 spécifie les procédures, les conditions et les méthodes d'essai selon lesquelles les paramètres principaux et les caractéristiques de fonctionnement principales des fours à arc submergé dont les niveaux de puissance électrique assignée sont supérieurs à 500 kVA sont établis. La présente norme est applicable aux fours à arc submergé à une ou plusieurs électrodes. Afin de déterminer d'autres évaluations techniques ou économiques, des essais supplémentaires peuvent être nécessaires. Les essais pour des équipements spéciaux des fours commandés par convertisseur à semiconducteurs, tels que les redresseurs commandés ou les convertisseurs à courant alternatif commandés, sont couverts par la CEI 60146-1-1. Cette deuxième édition annule et remplace l'édition précédente parue en 1980, dont elle constitue une révision technique. Les modifications techniques importantes par rapport à l'édition précédente sont les suivantes: - Article 1 (Domaine d'application et objet) - les types de fours couverts par la présente norme sont définis plus clairement. - L'Article 2 (Références normatives) et l'Article 3 (Termes et définitions) ont été mis à jour et complétés. - Un nouvel Article 4 (Caractéristiques du système de four à arc submergé) a été ajouté; il traite principalement des essais nécessaires pour les équipements électriques à haute tension/haute intensité de l'installation. - L'Article 5 (Essais et conditions générales) et l'Article 6 (Essais techniques) ont été modifiés en fonction des exigences actuelles pour l'utilisation d'un four à arc submergé en toute sécurité.",PE

Oprema za industrijsko električno ogrevanje - Preskusne metode za peči z zakritim oblokom

Ta mednarodni standard določa preskusne postopke, pogoje in metode, po katerih so vzpostavljeni glavni parametri in glavne značilnosti delovanja peči z zakritim oblokom (SAF) z ravnmi nazivne električne moči nad 500 kVA. Ta standard se uporablja za peči z zakritim oblokom z eno elektrodo ali več. Za določanje dodatnih tehničnih ali ekonomskih ocen so morda potrebni dodatni preskusi. Preskusi za nekatero posebno opremo za peči, ki se nadzorujejo s polprevodnimi pretvorniki, na primer z nadzorovanimi usmerniki ali nadzorovanimi izmeničnimi pretvorniki, so zajeti v standardu IEC 60146-1-1.

INDUSTRIAL ELECTROHEATING EQUIPMENT –
TEST METHODS FOR SUBMERGED-ARC FURNACES
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.

International Standard IEC 60683 has been prepared by IEC technical committee 27:

Industrial electroheating.

This second edition cancels and replaces the previous edition published in 1980 and

constitutes a technical revision.

Significant technical changes with respect to the previous edition are as follows:

– Clause 1 (Scope and object) – the types of furnaces covered by this standard are more

clearly defined.
– Clause 2 (Normative references) and Clause 3 (Terms and definitions) have been
updated and completed.

– A new Clause 4 (Features of the SAF sytem) has been added; it mainly concentrates

on the tests necessary for high voltage/high current electrical equipment in the
installation.

– Clause 5 (Tests and general conditions) and Clause 6 (Technical tests) have been

modified according to today's requirements for safe operation of a SAF.

TEST METHODS FOR SUBMERGED-ARC FURNACES
1 Scope and object

This International Standard specifies test procedures, conditions and methods according to

which the main parameters and the main operational characteristics of a submerged-arc

furnace (SAF) with rated electrical power levels above 500 kVA are established.
This standard is applicable to SAF with one or more electrodes.

In order to determine further technical or economic assessments, additional tests may be

necessary.

Tests for some special equipment for semiconductor converter controlled furnaces, such as

controlled rectifiers or controlled a.c. converters, are covered by IEC 60146-1-1.
