Anotation

IEC 60252-1:2010+A1:2013 applies to motor capacitors intended for connection to windings of asynchronous motors supplied from a single-phase system having a frequency up to and including 100 Hz, and to capacitors to be connected to three-phase asynchronous motors so that these motors may be supplied from a single-phase system. This standard covers impregnated or unimpregnated capacitors having a dielectric of paper, plastic film, or a combination of both, either metallized or with metal-foil electrodes, with rated voltages up to and including 660 V. This edition includes the following significant technical changes with respect to the previous edition: - the definition of "segmented capacitors" has been added in 3.6; - the definition of "classes of operation" has been clarified, with the addition of the concept of "probable life" with reference to statistics, in 3.9; - the following wording "Operation above the rated voltage will reduce the life expectancy of the capacitor" has been introduced in 6.1. - some clarifications have been added to Clause 8, Marking, mainly for small capacitors. This consolidated version consists of the second edition (2010) and its amendment 1 (2013). Therefore, no need to order amendment in addition to this publication. La CEI 60252-1:2010+A1:2013 sapplique aux condensateurs destines a etre raccordes aux enroulements des moteurs asynchrones alimentes par un reseau monophase dont la frequence ne depasse pas 100 Hz, et aux condensateurs destines aux moteurs asynchrones triphases pour permettre le raccordement de ces moteurs a un reseau monophase. La presente norme couvre les condensateurs impregnes ou non, ayant un dielectrique en papier, film plastique ou une combinaison des deux, soit metallises, soit a electrodes en feuilles de metal, pour une tension assignee nexcedant pas 660 V. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - la definition de "condensateur a film segmente" a ete ajoutee en 3.6; - la definition de "classes dutilisation" a ete clarifiee, avec lajout du concept de "duree de vie probable" et des references aux statistiques, en 3.9; - la phrase "Un fonctionnement au-dessus de la tension assignee reduira la duree de vie du condensateur" a ete introduite en 6.1; - quelques clarifications ont ete ajoutees dans lArticle 8: Marquage, principalement pour les petits condensateurs. Cette version consolidee comprend la deuxieme edition (2010) et son amendement 1 (2013). Il nest donc pas necessaire de commander lamendement avec cette publication.
