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).
