SIST EN IEC 62772:2024

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 (IEC 62772:2023)

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).

Hohlkern-Verbundstützisolatoren für Schaltanlagen mit einer Wechselspannung über 1 000 V und einer Gleichspannung über 1 500 V - Begriffe, Prüfverfahren und Annahmekriterien (IEC 62772:2023)

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)

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.

Votli kompozitni podporni izolatorji za postaje z izmeničnimi napetostmi, višjimi od 1000 V, in enosmernimi napetostmi, višjimi od 1500 V - Definicije, preskusne metode in merila sprejemljivosti (IEC 62772:2023)

Ta mednarodni standard se uporablja za votle kompozitne izolatorje, sestavljene iz nosilne izolacijske cevi iz vlaken, impregniranih s smolo, ohišja (na zunanji strani izolacijske cevi) iz polimernega materiala (npr. iz silikona ali etilen-propilena) in kovinskih pritrdil ob koncih izolacijske cevi. Votli kompozitni izolatorji, kot so opredeljeni v tem standardu, niso namenjeni splošni uporabi (ki ni pod tlakom) ali uporabi s stalnim tlakom plina (pod tlakom). Namenjeni so za uporabo tako v zunanji kot notranji električni opremi, ki deluje z izmeničnim tokom z izmenično nazivno napetostjo, večjo od 1000 V in frekvenco največ 100 Hz, ali za uporabo v opremi z enosmernim tokom in nazivno enosmerno napetostjo, večjo od 1500 V.
Namen tega standarda je:
– definirati uporabljene izraze;
– določiti preskusne metode;
– določiti merila sprejemljivosti.
Votli izolatorji so vgrajeni v električno opremo, ki je električno tipsko preskušena, kot to zahteva veljavni standard za opremo. Zato ni predmet tega standarda, da predpiše tipske dielektrične preskuse, saj udarne napetosti in trdnost in preskoki niso značilni za same votle izolatorje, ampak za aparat, katerega del je votli izolator.
Vsi preskusi v okviru tega standarda, razen toplotno-mehanskega preskusa, se izvajajo pri običajni temperaturi okolja. Ta standard ne določa preskusov, ki so morda značilni za napravo, katere del je votli izolator.
Votli kompozitni izolatorji so namenjeni za uporabo v električni opremi, kar med drugim vključuje:
– visokonapetostne odklopnike,
– stikala/ločilna stikala,
– ločilnike,
– postajne izolatorje,
– odklopne odklopnike,
– ozemljitvena stikala,
– merilne in močnostne transformatorje,
– uvodnice,
– kabelske zaključke.
Dodatno preskušanje, ki je opredeljeno v zadevnem standardu IEC za opremo, je lahko potrebno.
