Railway applications - Rolling stock equipment - Capacitors for power electronics - Part 1: Paper/plastic film capacitors

IEC 61881-1:2010 applies to capacitors for power electronics intended to be used on rolling stock. The rated voltage of capacitors is limited to 10 000 V. The operating frequency of the systems in which these capacitors are used is usually up to 15 kHz, while the pulse frequencies may be up to 5 to 10 times the operating frequency. Distinguishes between AC and DC capacitors.

Applications ferroviaires - Matériel roulant - Condensateurs pour électronique de puissance - Partie 1: Condensateurs papier et film plastique

La CEI 61881-1:2010 s'applique aux condensateurs pour électronique de puissance destinés à être utilisés sur le matériel roulant. La tension assignée des condensateurs est limitée à 10 000 V. La fréquence de fonctionnement des systèmes dans lesquels ces condensateurs sont utilisés atteint généralement jusqu'à 15 kHz, tandis que les fréquences d'impulsion peuvent atteindre de 5 à 10 fois la fréquence de fonctionnement. Une distinction est faite entre les condensateurs pour courant alternatif et ceux pour courant continu.

Železniške naprave - Oprema voznih sredstev - Kondenzatorji za močnostno elektroniko - 1. del: Zahteve, preskusi in splošne informacije (IEC 61881-1:2010)

Ta del IEC 61881 velja za kondenzatorje za močnostno elektroniko, namenjeno uporabi pri voznih sredstvih. Ocenjena napetost kondenzatorjev, zajeta v tem delu, je omejena do 10.000 V. Delovne frekvence sistemov, v katerih so kondenzatorji uporabljeni, so običajno do 15 kHz, medtem ko so pulzne frekvence lahko od 5- do 10-krat večje od delovnih frekvenc. Razlikuje med kondenzatorji z izmeničnim tokom in enosmernim tokom. Štejejo se kot sestavni deli, vgrajeni v ohišja. OPOMBA Ta standard zajema izjemno širok razpon tehnologij kondenzatorjev za različne uporabe: prenapetostna zaščita, filtriranje za enosmerni tok in izmenični tok, komutirana vezja, shranjevanje enosmerne energije, pomožni razsmerniki itd. Primeri so podani v klavzuli 9. Iz tega standarda so izvzeti: – kondenzatorji za obrate z indukcijsko proizvodnjo toplote, ki delujejo pri frekvencah med 40 Hz in 24.000 Hz (glej IEC 60100-1 in 60110-2); – kondenzatorji za uporabo v motorjih in podobno uporabo (glej IEC 60252-1 in IEC 60252-2); – kondenzatorji za uporabo v vezjih za blokiranje enega ali več harmonik v omrežnem napajanju; – majhni kondenzatorji za izmenični tok, kot se uporabljajo v fluorescenčnih lučeh in sijalkah (glej IEC 61048 in 61049); – kondenzatorji za dušenje radijskih motenj (glej IEC 60384-14); – ranžirni kondenzatorji za sisteme z izmeničnih tokom, ki ima ocenjeno napetost na 1000 V (glej IEC 60871-1 in IEC 60871-2); – ranžirni kondenzatorji samo okrevalne vrste za sisteme z izmeničnim tokom, ki imajo ocenjeno napetost do vključno z 1000 V (glej IEC 60831-1 in IEC 60831-2); – ranžirni kondenzatorji, ki niso samo okrevalne vrste, za sisteme z izmeničnim tokom, ki imajo ocenjeno napetost do vključno z 1000 V (glej IEC 60931-1 in IEC 60931-2); – serijski kondenzatorji za sisteme napajanja (glej IEC 60143-1, IEC 60143-2 in IEC 60143-3); - sklopni kondenzatorji in ločevalniki kondenzatorjev (glej IEC 60358); - kondenzatorji za aplikacije, ki potrebujejo shranjevanje energije/razelektritev pri visokih napetostih kot fotokopirni stroji in laserji; – kondenzatorji za mikrovalovne pečice; - kondenzatorji za močnostno elektroniko (glej IEC 61071).

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 61881-1 has been prepared by IEC technical committee 9: Electrical

equipment and systems for railways.
IEC 61881-1 cancels and replaces IEC 61881 (1999).
The text of this standard is based on the following documents:
FDIS Report on voting
9/1405/FDIS 9/1454/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to

CAPACITORS FOR POWER ELECTRONICS –
Part 1: Paper/plastic film capacitors
1 Scope

This part of IEC 61881 applies to capacitors for power electronics intended to be used on

rolling stock.
The rated voltage of capacitors covered by this part is limited to 10 000 V.

The operating frequency of the systems in which these capacitors are used is usually up to

15 kHz, while the pulse frequencies may be up to 5 to 10 times the operating frequency.

It distinguishes between AC and DC capacitors.
They are considered as components mounted in enclosures.

NOTE This standard covers an extremely wide range of capacitor technologies for numerous applications:

overvoltage protection, DC and AC filtering, switching circuits, DC energy storage, auxiliary inverters, etc.

Examples are given in Clause 9.
The following are excluded from this standard:

– capacitors for induction heat-generating plants operating at frequencies between 40 Hz and

24 000 Hz (see IEC 60110-1 and 60110-2);

– capacitors for motor applications and the like (see IEC 60252-1 and IEC 60252-2);

– capacitors to be used in circuits for blocking one or more harmonics in power supply

networks;

– small AC capacitors as used for fluorescent and discharge lamps (see IEC 61048 and

IEC 61049);
– capacitors for suppression of radio interference (see IEC 60384-14);

– shunt capacitors for AC power systems having a rated voltage above 1 000 V (see

IEC 60871-1 and IEC 60871-2);

– shunt power capacitors of the self-healing type for AC systems having a rated voltage up to

and including 1 000 V (see IEC 60831-1 and IEC 60831-2);
