High-voltage switchgear and controlgear - Part 202: AC prefabricated substations for rated voltages above 1 kV and up to and including 52 kV
This part of IEC 62271 specifies the service conditions, rated characteristics, general structural requirements and test methods of enclosed high-voltage prefabricated substations. These prefabricated substations are cable-connected to AC high-voltage networks with an operating voltage up to and including 52 kV and power frequencies up to and including 60 Hz. They can be manually operated from inside (walk-in type) or from outside (non-walk-in type). They are designed for outdoor installation at locations with public accessibility and where protection of personnel is provided. These prefabricated substations can be situated at ground level or partially or completely below ground level. The last are also called "underground prefabricated substations". In general, two types of prefabricated substations are considered in this document: - high-voltage switchgear prefabricated substations; - high-voltage/low-voltage transformer prefabricated substations (step-up and step-down). A high-voltage switchgear prefabricated substation comprises an enclosure containing in general the following electrical components: - high-voltage switchgear and controlgear; - auxiliary equipment and circuits. A high-voltage/low-voltage transformer prefabricated substation comprises an enclosure containing in general the following electrical components: - power transformer(s); - high-voltage and low-voltage switchgear and controlgear; - high-voltage and low-voltage interconnections; - auxiliary equipment and circuits. However, relevant provisions of this document are applicable to designs where not all these electrical components exist (for example, a prefabricated substation consisting of power transformer and low-voltage switchgear and controlgear). The listed electrical components of a high-voltage/low-voltage transformer prefabricated substation can be incorporated in the prefabricated substation either as separate components or as an assembly type CEADS according to IEC 62271-212. This document covers only designs using natural ventilation. However, relevant provisions of this document are applicable to designs using other means of ventilation except the rated power of the prefabricated substation and associated class of enclosure (see 5.101), the continuous current tests (see 7.5) and all temperature rise related requirements, which would need an agreement between manufacturer and user. NOTE 1 IEC 61936-1 [1]1 provides general rules for the design and erection of high-voltage power installations. As well, it specifies additional requirements for the external connections, erection and operation at the place of installation of high-voltage prefabricated substations compliant with IEC 62271-202, which are regarded as a component of such installation. Non-prefabricated high-voltage substations, are generally covered by IEC 61936-1 [1]. NOTE 2 High-voltage switchgear prefabricated substations can include instrument transformers, according to IEC 61869 (all parts). These substations are not high-voltage/low-voltage transformer prefabricated substations.

Appareillage à haute tension - Partie 202: Postes préfabriqués pour courant alternatif de tensions assignées supérieures à 1 kV et inférieures ou égales à 52 kV
L'IEC 62271-202:2022 spécifie les conditions de service, les caractéristiques assignées, les exigences structurelles générales et les méthodes d'essai applicables aux postes préfabriqués haute tension sous enveloppe. Ces postes préfabriqués sont connectés par câble à des réseaux haute tension à courant alternatif avec une tension de service inférieure ou égale à 52 kV et des fréquences de puissance inférieures ou égales à 60 Hz. Ces postes peuvent être manœuvrés de l'intérieur (à aire de manœuvre) ou de l'extérieur (sans aire de manœuvre). Ils sont conçus pour une installation extérieure en des emplacements accessibles au public et ils assurent la protection du personnel. Cette troisième édition annule et remplace la deuxième édition, parue en 2014. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
révision du contenu et de la structure de l'ensemble du document avec prise en considération toute particulière de l’IEC 62271-1:2017;
modification du titre et du domaine d’application afin d’inclure les postes préfabriqués de connexion haute tension;
inclusion d’un ECEPD comme composante potentielle d’un poste préfabriqué MT/BT;
au paragraphe 7.2.101, prise en considération nouvelle de l’influence potentielle des éléments environnants sur les performances diélectriques des composants à haute tension comme les appareillages à haute tension et les interconnexions haute tension sous enveloppe non métallique ou sans écran mis à la terre;
nouvelle Annex G informative avec procédure d'essai destinée à évaluer l’effet du rayonnement solaire sur les températures à l’intérieur de l’enveloppe et comment appliquer cette procédure;
nouvelle Annex H informative pour la prise en considération appropriée des conditions d’installation du matériel électronique;
la puissance assignée d’un poste préfabriqué est maintenant définie comme une valeur assignée à trois paramètres. Voir le paragraphe 5.101.1:
introduction de dimensions minimales pour les portes d’accès au poste préfabriqué (6.104.4) et pour la hauteur libre du couloir de manœuvre (6.105.3);
révision/clarification, lorsque cela est nécessaire, des méthodes d'essai (d’échauffement) au courant permanent;
correction de la Figure D.1, qui décrit le facteur de charge du transformateur de puissance immergé dans l’huile minérale à l’intérieur de l’enveloppe.
Visokonapetostne stikalne in krmilne naprave - 202. del: Montažne postaje AC za naznačene napetosti nad 1 kV do vključno 52 kV (IEC 62271-202:2022)
Ta del standarda IEC 62271 določa splošne pogoje delovanja, naznačene značilnosti, splošne strukturne zahteve in preskusne metode za visokonapetostne montažne postaje v ohišjih. Te montažne postajo so kabelsko povezane z izmeničnimi visokonapetostnimi omrežji z najvišjo delovno napetostjo do vključno 52 kV in najvišjimi omrežnimi frekvencami do vključno 60 Hz. Upravljati jih je mogoče ročno, in sicer z notranje (vrsta z vhodom) ali zunanje (vrsta brez vhoda) strani. Zasnovane so za zunanjo namestitev na javno dostopnih lokacijah, kjer je zagotovljena zaščita osebja.
Te montažne postaje se lahko nahajajo na tleh ali delno ali popolnoma pod površjem. Slednje imenujemo tudi podzemne montažne postaje.
V tem standardu sta obravnavani dve vrsti montažnih postaj:
– visokonapetostne stikalne montažne postaje;
– visoko-/nizkonapetostne transformatorske montažne postaje (z regulacijo navzgor in navzdol).
Visokonapetostna stikalna montažna postaja zajema ohišje, ki na splošno vsebuje naslednje električne komponente:
– visokonapetostne stikalne in krmilne naprave;
– pomožna oprema in vezja.
Visoko-/nizkonapetostna transformatorska montažna postaja zajema ohišje, ki na splošno vsebuje naslednje električne komponente:
– močnostni transformatorji;
– visokonapetostne ter nizkonapetostne stikalne in krmilne naprave;
– visokonapetostne ter nizkonapetostne povezave;
– pomožna oprema in vezja.
Vendar pa se zadevne določbe tega standarda uporabljajo za zasnove, pri katerih ne obstajajo vse te električne komponente (na primer montažna postaja, ki vključuje močnostni transformator ter nizkonapetostno stikalno in krmilno napravo).
Navedene električne komponente visokonapetostne/nizkonapetostne transformatorske montažne postaje se lahko v montažno postajo vključijo posamično ali kot del kompaktnih sestavov opreme za distribucijske podpostaje (CEADS) v skladu s standardom IEC 62271-212.
Ta standard zajema samo zasnove z naravnim prezračevanjem, vendar ustrezne določbe tega standarda veljajo tudi za zasnove, pri katerih se uporabljajo drugi načini prezračevanja, razen kar zadeva nazivno moč montažnih postaj in z njo povezano ohišje (glej točko 5.101), preskuse neprekinjenosti toka (glej točko 7.5) in vse zahteve, povezane z dvigom temperature, za katere je potreben dogovor med proizvajalcem in uporabnikom.
OPOMBA: Standard IEC 61936-1 [1] določa splošna pravila za načrtovanje in postavitev visokonapetostnih električnih inštalacij. V njem so navedene tudi dodatne zahteve za zunanje povezave, postavitev in obratovanje na mestu namestitve visokonapetostnih montažnih postaj v skladu s standardom IEC 62271-202, ki se obravnavajo kot komponenta take inštalacije. Nemontažne visokonapetostne postaje (483) so na splošno zajete v standardu IEC 61936-1 [1].
