Low-voltage switchgear and controlgear assemblies - Part 5: Assemblies for power distribution in public networks

IEC 61439-5:2014 defines the specific requirements for public electricity network distribution assemblies (PENDAs). PENDAs have the following criteria: - used for the distribution of electrical energy in three phase systems for which the rated voltage does not exceed 1 000 V a.c. (see Figure 101 for a typical distribution network); - open ASSEMBLIES are not covered by this standard; - suitable for installation in places where only skilled persons have access for their use, however, outdoor types may be installed in situations that are accessible to ordinary persons; - for indoor or outdoor use. This second edition cancels and replaces the first edition published in 2010. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the latest edition: - confirmation that tests carried out on the most onerous PENDA are deemed to verify the performance of similar and less onerous assemblies of the same general construction and rating; - more precise timing/conditions for impact force withstand tests for PENDAs designed for operation in an arctic climate; - correction of the direction of the applied force in the static load test.

Ensembles d'appareillage à basse tension - Partie 5: Ensembles pour réseaux de distribution publique

L'IEC 61439-5:2014 définit les exigences spécifiques aux ensembles pour réseaux de distribution publique (ERD). Les ERD satisfont aux critères suivants: - ils sont utilisés pour la distribution de l'énergie électrique dans des systèmes triphasés pour lesquels la tension assignée ne dépasse pas 1 000 V en courant alternatif (se reporter à la Figure 101 représentant un réseau de distribution classique); - ils sont fixes; - les ENSEMBLES ouverts ne sont pas couverts par la présente norme; - ils sont adaptés à une installation dans des emplacements où seules des personnes qualifiées ont accès pour leur utilisation; cependant, des ERD pour l'extérieur peuvent être installés dans des endroits susceptibles d'être accessibles à des personnes ordinaires; - utilisation à l'intérieur ou à l'extérieur. Cette deuxième édition annule et remplace la première édition parue en 2010. Elle constitue une révision technique. La présente édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - confirmation que les essais effectués sur les ERD les plus exigeants sont présumés vérifier la performance des ensembles analogues et moins exigeants de mêmes constructions générales et valeurs assignées; - conditions/ durées plus précises pour les essais de résistance à l'impact des ERD conçus pour fonctionner sous un climat arctique; - correction de la direction de la force appliquée lors de l'essai de charge statique.

Sestavi nizkonapetostnih stikalnih in krmilnih naprav - 5. del: Sestavi za distribucijo električne energije v javnih omrežjih (IEC 61439-5:2014)

Ta del standarda IEC 61439 določa posebne zahteve za sestave za distribucijo električne energije v javnih omrežjih (PENDA).
Sestavi za distribucijo električne energije v javnih omrežjih imajo naslednje kriterije:
– uporabljajo se za distribucijo električne energije v trifaznih sistemih, katerih nazivna napetost ne presega 1000 V izmeničnega toka (glej sliko 101 – tipično distribucijsko omrežje);
– stacionarni;
– ta standard ne zajema odprtih SESTAVOV;
– primerni za namestitev v prostorih, do katerih ima dostop le usposobljeno osebje, vendar se lahko namestijo tudi zunanje enote, kadar so te dostopne laikom;
– za notranjo in zunanjo uporabo.
Namen tega standarda je navesti definicije in določiti pogoje uporabe, konstrukcijske zahteve, tehnične značilnosti in preskuse za sestave za distribucijo električne energije v javnih omrežjih. Glede na parametre omrežja so lahko potrebni preskusi na višji ravni delovanja.
Sestavi za distribucijo električne energije v javnih omrežjih lahko vsebujejo tudi krmilne in/ali signalne naprave, povezane z distribucijo električne energije.
Ta standard se uporablja za vse SESTAVE, ne glede na to, ali so oblikovani, proizvedeni enkratno ali v celoti standardizirani in proizvedeni v velikih količinah.
Proizvodnjo in/ali sestavljanje lahko izvaja oseba, ki ni prvotni proizvajalec (glej 3.10.1 standarda IEC 61439-1:2011).
Ta standard se ne uporablja za posamezne naprave in samostojne dele, kot so zaganjalniki, varovalna stikala, elektronska oprema itd., ki so skladni z ustreznimi standardi za izdelek.
Ta standard se ne uporablja za posebne vrste SESTAVOV, ki so zajeti v drugih delih skupine standardov IEC 61439.

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 61439-5 has been prepared by subcommittee 17D: Low-voltage

switchgear and controlgear assemblies, of IEC technical committee 17: Switchgear and

controlgear.

This second edition cancels and replaces the first edition published in 2010. It constitutes a

technical revision.

This edition includes the following significant technical changes with respect to the latest

edition:

– confirmation that tests carried out on the most onerous PENDA are deemed to verify the

performance of similar and less onerous assemblies of the same general construction and

rating;

– more precise timing/conditions for impact force withstand tests for PENDAs designed for

operation in an arctic climate;
– correction of the direction of the applied force in the static load test.

LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR ASSEMBLIES –
Part 5: Assemblies for power distribution in public networks
1 Scope

This part of IEC 61439 defines the specific requirements for public electricity network

distribution assemblies (PENDAs).
PENDAs have the following criteria:

– used for the distribution of electrical energy in three phase systems for which the rated

voltage does not exceed 1 000 V a.c. (see Figure 101 for a typical distribution network);

– stationary;
– open ASSEMBLIES are not covered by this standard;

– suitable for installation in places where only skilled persons have access for their use,

however, outdoor types may be installed in situations that are accessible to ordinary

persons;
– for indoor or outdoor use.

The object of this standard is to state the definitions and to specify the service conditions,

construction requirements, technical characteristics and tests for PENDAs. Network

parameters may require tests at higher performance levels.

PENDAs may also include control and or signalling devices associated with the distribution of

electrical energy.

This standard applies to all PENDAs whether they are designed, manufactured on a one-off

basis or fully standardised and manufactured in quantity.

The manufacture and/or assembly may be carried out other than by the original manufacturer

(see 3.10.1 of IEC 61439-1:2011).

This standard does not apply to individual devices and self-contained components, such as

motor starters, fuse switches, electronic equipment, etc. which comply with the relevant

product standards.

This standard does not apply to specific types of ASSEMBLIES covered by other parts of

IEC 61439 series.

MEDNARODNA ELEKTROTEHNIŠKA KOMISIJA
SESTAVI NIZKONAPETOSTNIH STIKALNIH IN KRMILNIH NAPRAV –
5. del: Sestavi za distribucijo električne energije v javnih omrežjih
PREDGOVOR

1) IEC (Mednarodna elektrotehniška komisija) je svetovna organizacija za standardizacijo, ki združuje vse nacionalne

elektrotehnične komiteje (nacionalni komiteji IEC). Cilj IEC je pospeševati mednarodno sodelovanje v vseh vprašanjih

standardizacije s področja elektrotehnike in elektronike. V ta namen poleg drugih aktivnosti izdaja mednarodne standarde,

tehnične specifikacije, tehnična poročila, javnosti dostopne specifikacije (PAS) in vodila (v nadaljevanju: publikacije IEC). Za

njihovo pripravo so odgovorni tehnični odbori. Vsak nacionalni komite IEC, ki ga zanima obravnavana tema, lahko sodeluje v

tem pripravljalnem delu. Prav tako lahko v pripravi sodelujejo mednarodne organizacije ter vladne in nevladne ustanove, ki

so povezane z IEC. IEC deluje v tesni povezavi z mednarodno organizacijo za standardizacijo ISO skladno s pogoji,

določenimi v soglasju med obema organizacijama.

2) Uradne odločitve ali sporazumi IEC o tehničnih vprašanjih, pripravljeni v tehničnih odborih, v katerih so prisotni vsi nacionalni

komiteji, ki jih tema zanima, izražajo, kolikor je mogoče, mednarodno soglasje o obravnavani temi.

3) Publikacije IEC imajo obliko priporočil za njihovo uporabo na mednarodni ravni in jih kot takšne sprejmejo nacionalni komiteji

IEC. Čeprav IEC skuša na vse primerne načine zagotavljati točnost tehničnih vsebin v publikacijah IEC, IEC ne more biti

odgovoren za način, kako se določila uporabljajo, ter za morebitne napačne razlage končnih uporabnikov.

4) Da bi pospeševali mednarodno poenotenje, so se nacionalni komiteji IEC zavezali, da bodo v svojih nacionalnih in regionalnih

standardih čim pregledneje uporabljali mednarodne standarde. Vsako odstopanje med standardom IEC in ustreznim

nacionalnim ali regionalnim standardom je treba v slednjem jasno označiti.

5) IEC sam ne izvaja potrjevanja skladnosti. Storitve ugotavljanja skladnosti in na nekaterih območjih tudi dostop do znakov

skladnosti IEC izvajajo neodvisni certifikacijski organi. IEC ne prevzema nikakršne odgovornosti za storitve, ki jih izvajajo

neodvisni certifikacijski organi.
6) Vsi uporabniki naj bi si zagotovili zadnjo izdajo teh publikacij.

7) IEC ali njegovi direktorji, zaposleni, uslužbenci ali agenti, vključno s samostojnimi strokovnjaki ter člani tehničnih odborov in

nacionalnih komitejev IEC, ne prevzemajo nobene odgovornosti za kakršno koli osebno poškodbo, škodo na premoženju ali

katero koli drugo škodo kakršne koli vrste, bodisi posredne ali neposredne, ali za stroške (vključno z zakonitim lastništvom)

in izdatke, povezane s publikacijo, njeno uporabo ali zanašanjem na to publikacijo IEC ali katero koli drugo publikacijo IEC.

8) Pozornost je treba posvetiti normativnim virom, na katere se sklicuje ta publikacija. Uporaba navedenih publikacij je nujna za

pravilno uporabo te publikacije.

9) Opozoriti je treba na možnost, da bi lahko bil kateri od elementov tega mednarodnega standarda predmet patentnih pravic.

IEC ni odgovoren za identificiranje nobene od teh patentnih pravic.

Mednarodni standard IEC 61439-5 je pripravil pododbor 17D Sestavi nizkonapetostnih stikalnih in

krmilnih naprav pri tehničnem odboru IEC 17 Stikalne in krmilne naprave.

Ta druga izdaja razveljavlja in nadomešča prvo izdajo, objavljeno v letu 2010. Pomeni tehnično revizijo.

Ta izdaja vsebuje naslednje pomembne tehnične spremembe glede na zadnjo izdajo:

– potrjeno je, da se preskusi, opravljeni na najzahtevnejši PENDA, štejejo za dokaz učinkovitosti

podobnih in manj zahtevnih sklopov iste splošne konstrukcije in stopnje;

– natančneje so določeni čas/pogoji za preskuse zdržnosti glede na silo udarca za PENDA, zasnovane

za delovanje v arktičnem podnebju;
– popravljena je smer delujoče sile v statičnem preskusu obremenitve.

SIST EN 61439-5 : 2015
1 Področje uporabe

Ta del standarda IEC 61439 opredeljuje specifične zahteve za sestave za distribucijo električne energije

v javnih omrežjih (PENDA).
PENDA imajo naslednje kriterije:

– se uporabljajo za distribucijo električne energije v trifaznih sistemih, pri katerih naznačena napetost

ne presega 1 000 V izmenično (glej sliko 101 za tipično distribucijsko omrežje);
– so stacionarni;
– odprti SESTAVI niso zajeti v tem standardu;

– so primerni za namestitev na mestih, kjer imajo dostop do njihove uporabe le strokovne osebe;

kljub temu pa se vrste za namestitev na prostem lahko namestijo na mestih, dostopnih laikom;

– so za zunanjo in notranjo uporabo.

Namen tega standarda je navesti definicije in določiti obratovalne pogoje, konstrukcijske zahteve,

tehnične lastnosti in preskuse za PENDA. Parametri omrežja lahko zahtevajo preskuse na višji ravni

delovanja.

PENDA lahko vključujejo tudi krmilne in signalizacijske naprave, povezane z distribucijo električne

energije.

Ta standard se nanaša na vse PENDA ne glede na to, ali so zasnovani, izdelani na enkratni osnovi ali

pa so povsem standardizirani in proizvedeni v večji količini.

Proizvodnjo in/ali montažo lahko izvajajo tudi drugi in ne samo prvotni proizvajalec (glej 3.10.1 v

standardu IEC 61439-1:2011).

Ta standard ne velja za posamezne naprave in samostojne sestavne dele, kot so motorski zaganjalnik,

varovalčna stikala, elektronska oprema itd., ki so skladni z ustreznimi standardi za proizvode.

Ta standard ne velja za specifične tipe SESTAVOV, ki so zajeti v drugih delih skupine IEC 61439.

Slika 101: Tipično distribucijsko omrežje
---------------------- Page: 11 ----------------------
SIST EN 61439-5 : 2015
