EN 61558-2-20:2011

Safety of transformers, reactors, power supply units and combinations thereof - Part 2-20: Particular requirements and tests for small reactors

IEC 61558-2-20:2010 deals with the safety of small reactors for general applications. This part is applicable to stationary or portable, single-phase or polyphase, air-cooled (natural or forced) general purpose reactors including alternating current, premagnetised and current compensated independent or associated reactors. This second edition cancels and replaces the first edition published in 2000. It constitutes a technical revision. The main changes consist of updating this part in accordance with IEC 61558-1:2005. This part has the status of a group safety publication in accordance with IEC Guide 104. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months from the date of publication. In the meantime, the previous edition can still be ordered by contacting your local IEC member National Committee or the IEC Central Office.

Sicherheit von Transformatoren, Drosseln, Netzgeräten und entsprechende Kombinationen - Teil 2-20: Besondere Anforderungen und Prüfungen an Kleindrosseln

Sécurité des transformateurs, bobines d'inductance, blocs d'alimentation et combinaisons de ces éléments - Partie 2-20: Règles particulières et essais pour les petites bobines d'inductance

La CEI 61558-2-20:2010 traite de la sécurité des petites bobines d'inductance pour applications d'ordre général. La présente partie est applicable aux bobines d'inductance fixes ou mobiles, monophasées ou polyphasées, à refroidissement par air (circulation naturelle ou forcée), pour usage général, incluant les bobines d'inductance à courant alternatif, prémagnétisées et à courant compensé, indépendantes ou associées. Cette deuxième édition annule et remplace la première édition publiée en 2000. Elle constitue une révision technique. Les principales modifications consistent en la mise à jour de la présente partie conformément à la CEI 61558-1:2005. La présente partie a le statut de publication groupée de sécurité conformément au Guide CEI 104. L'attention des Comités Nationaux est attirée sur le fait que les fabricants d'appareils et les organismes d'essai peuvent avoir besoin d'une période transitoire après la publication d'une nouvelle publication CEI, ou d'une publication amendée ou révisée, pour fabriquer des produits conformes aux nouvelles exigences et pour adapter leurs équipements aux nouveaux essais ou aux essais révisés. Le comité recommande que le contenu de cette publication soit entériné au niveau national au plus tôt 12 mois après la date de publication.

Varnost transformatorjev, dušilk, napajalnikov in podobnih izdelkov - 2-20. del: Posebne zahteve in preskusi za majhne reaktorje (IEC 61558-2-20:2010)

Nadomestilo:
ta del IEC 61558 obravnava varnost majhnih reaktorjev za splošne uporabe.
OPOMBA 1: Varnost vključuje električne, toplotne in mehanske vidike.
Razen če je drugače določeno, od tu naprej pojem transformator ali reaktor zajema majhne
reaktorje.
Ta del velja za fiksne ali prenosne, enofazne ali večfazne, zračno hlajene (naravno
ali vsiljeno) reaktorje za splošne namene, vključno z reaktorji z izmeničnim tokom, vnaprej namagnetene in tokovno
kompenzirane neodvisne ali povezane reaktorje.
Ocenjena napetost napajanja ne presega 1.000 V izmeničnega toka ali 1 500 V enosmernega toka brez nihanja, ocenjena frekvenca napajanja in notranja obratovalna frekvenca pa ne presegata 1 MHz.
Ocenjena moč ne presega:
– 25 kVAR izmeničnega toka (25 kW enosmernega toka) za enofazne reaktorje,
– 50 kVAR izmeničnega toka (50 kW enosmernega toka) za večfazne reaktorje.
Ta del velja za reaktorje brez omejitve ocenjene moči, ki je predmet dogovora med kupcem in proizvajalcem.
Ta del velja za reaktorje suhega tipa. Navitje je lahko inkapsulirano ali nekapsulirano.
Ta del ne velja za:
– reaktorje, ki jih zajema IEC 60289,
– balast za fluorescenčne cevi, ki jih zajema IEC 61347-2-8,
– balast za sijalke (razen svetil s fluorescenčnimi cevmi), zajete v IEC 61347-2-9.
OPOMBA 2: Za reaktorje, polnjene s tekočim dielektrikom ali mletim materialom, kot je na primer pesek, se obravnavajo dodatne zahteve.
OPOMBA 3: Upoštevati je treba naslednje:
– za reaktorje, namenjene uporabi v vozilih, na krovih ladij in v zračnih plovilih, so lahko potrebne dodatne zahteve (iz drugih standardov, ki veljajo, državnih pravil itd.),
– meritve za zaščito ohišij in komponent v ohišjih pred zunanjimi vplivi, kot so plesen, mrčes, termiti, sončno sevanje in led, je prav tako treba upoštevati,
– različne pogoje za transport, hranjenje in delovanje reaktorja, je prav tako treba upoštevati,
– dodatne zahteve v skladu z drugimi primernimi standardi in državnimi pravili lahko veljajo za reaktorje, namenjene uporabi v posebnih okoljih, kot je tropsko okolje.
OPOMBA 4: Običajno so reaktorji namenjeni združevanju z opremo za funkcionalne zahteve opreme ali z zahtevami inštalacijskih pravil ali drugih specifikacij naprave.
OPOMBA 5: Reaktorji, ki vsebujejo elektronska vezja in komponente, so prav tako zajeti v tem standardu.
OPOMBA 6: Zaščita pred električnim udarom je lahko zagotovljena (ali dopolnjena) z drugimi deli ali značilnostmi opreme, kot je na primer ohišje.
OPOMBA 7: Reaktorji za nekatere uporabe bodo v prihodnosti zajeti v komplementarnih normativnih dodatkih.
OPOMBA 8: Prihodnji tehnološki razvoj reaktorjev je lahko potreben zaradi dviga zgornje meje frekvenc, do takrat pa se lahko ta del uporablja kot dokument s smernicami.
