FprEN IEC 62772:2023

Composite hollow core station post insulators with a.c. voltage greater than 1 000 V and d.c. voltage greater than 1 500 V - Definitions, test methods and acceptance criteria

This International Standard applies to composite hollow core station post insulators consisting of a load-bearing insulating tube (core) made of resin impregnated fibres, insulating filler material (solid, liquid, gaseous - pressurized or unpressurized), a housing (outside the insulating tube) made of polymeric material (for example silicone or ethylene-propylene) and fixing devices at the ends of the insulating tube. Composite hollow core station post insulators as defined in this standard are intended for general use in substations in both, outdoor and indoor environments, operating with a rated AC voltage greater than 1 000 V a.c. and a frequency not greater than 100 Hz or for use in direct current systems with a rated voltage greater than 1 500 V.d.c. The object of this standard is: to define the terms used; to prescribe test methods; to prescribe acceptance criteria. All the tests in this standard, apart from the thermal-mechanical test, are performed at normal ambient temperature. This standard does not prescribe tests that are characteristic of the apparatus of which the composite hollow core station post insulator ultimately may form a part (e.g. disconnector switch, reactor support, HVDC valves).

Isolateurs supports composites creux présentant une tension alternative supérieure à 1 000 V et une tension continue supérieure à 1 500 V - Définitions, méthodes d'essai et critères d'acceptation

IEC 62772:2023 est disponible sous forme de IEC 62772:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 62772:2023 s’applique aux isolateurs supports composites creux qui sont constitués d’un tube (noyau) isolant en fibres imprégnées de résine supportant la charge mécanique, d’un matériau de charge interne (solide, liquide, gaz, sous pression ou pas), d’un revêtement en polymère à l’extérieur du tube isolant (par exemple silicone ou éthylène-propylène) et de dispositifs de fixation à ses extrémités. Les isolateurs supports composites creux, tels que définis dans la présente norme, sont destinés à l’utilisation générale dans les postes, tant en extérieur qu’en intérieur. Ils fonctionnent avec une tension alternative assignée de plus de 1 000 V en courant alternatif et à une fréquence maximale de 100 Hz, ou sont utilisés dans les systèmes à courant continu avec une tension assignée supérieure à 1 500 V en courant continu. Le présent document a pour objet: - de définir les termes utilisés; - de spécifier des méthodes d’essai; - de spécifier les critères d’acceptation.
