Anotation

IEC 62271-209:2019 covers the connection assembly of fluid-filled and extruded cables to gas-insulated metal enclosed switchgear (GIS), in single- or three-phase arrangements where the cable terminations are fluid-filled or dry-type and there is a separating insulating barrier between the cable insulation and the gas insulation of the switchgear. This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) New numbering in accordance with ISO/IEC directives, Part 2 (2016) and to IEC 62271-1:2017; b) Clause 3: addition of a definition for plug-in cable termination, filling pressure and minimum function pressure for insulation; c) Clause 7: An additional dielectric type test for plug-in cable termination was added; also a pressure type test as well as a leak rate test on the insulator of a cable termination was implemented; d) Clause 12: New clause about safety practices; e) Clause 13: New clause about influence of the product on the environment; f) New informative Annex A: Mechanical forces applied on the flange of the cable connection enclosure. LIEC 62271-209:2019 est applicable a lassemblage de raccordement de cables remplis d’un fluide ou a isolation extrudee au poste sous enveloppe metallique (PSEM), dans une disposition unipolaire ou tripolaire. Les extremites de cable sont remplies d’un fluide ou de type sec et une separation isolante se trouve entre le fluide disolation du cable et lisolation gazeuse de lappareillage. Cette deuxieme edition annule et remplace la premiere edition parue en 2007. Cette edition constitue une revision technique. Cette edition inclut les modifications majeures suivantes par rapport a ledition precedente: a) Nouvelle numerotation conformement aux directives ISO/IEC, Partie 2 (2016) et a l’IEC 62271-1:2017; b) Article 3: ajout des definitions dextremite de cable embrochable, de pression de remplissage et de pression minimale de fonctionnement; c) Article 7: Un essai dielectrique de type complementaire pour les extremites de cables embrochables a ete ajoute; un essai de pression de type ainsi qu’un essai de taux de fuite type pour lisolateur des extremites de cable ont egalement ete appliques; d) Article 12: Nouvel article relatif aux pratiques en matiere de securite; e) Article 13: Nouvel article relatif a l’influence du produit sur l’environnement; f) Nouvelle Annexe A informative: Forces mecaniques appliquees sur la bride de l’enveloppe du raccordement de cable.
