(Main)Compact Equipment Assembly for Distribution Substations (CEADS)
Compact Equipment Assembly for Distribution Substations (CEADS)
This European Standard specifies the service conditions, rated characteristics, general structural requirements and test methods of the prefabricated assembly of the main electrical functional units of a HV/LV Distribution Substation, duly interconnected, for alternating current of rated voltages above 1 kV and up to and including 52 kV on the HV side, service frequency 50 Hz. This assembly is to be cable-connected to the network. This Compact Equipment Assembly for Distribution Substation (CEADS) as defined in this standard is designed and tested to be a single product with a single serial number and one set of documenta- tion. Such equipment is delivered as single transport unit, unless transport and/or erection condi- tions make it difficult or impossible. A CEADS is not a Distribution Substation, either prefabricated (covered by EN 62271-202) or not (covered by EN 61936-1:200X). However CEADS is intended to become part of a Distribution Sub- station assembling the HV equipment, the power transformer and the LV equipment duly intercon- nected (see Annex C, which also explains the origin and types of CEADS).
Hochspannungs-Schaltgeräte und -Schaltanlagen - Kompakte Schaltgerätekombinationen für Verteilungsstationen
Diese Europäische Norm beschreibt die Betriebsbedingungen, Bemessungswerte, allgemeine konstruktive Anforderungen und Prüfverfahren für fabrikfertige Gerätekombinationen der bestimmungsgemäß mitein¬ander verbundenen elektrischen Hauptfunktionseinheiten einer Hoch-/Niederspannungs(HS/NS)-Vertei¬lungsstation, für Wechselstrom bei Bemessungs-Betriebsspannungen über 1 kV bis einschließlich 52 kV auf der HS-Seite und für eine Betriebsfrequenz von 50 Hz. Diese Gerätekombination ist mit einer Kabel¬verbindung an das Netz anzuschließen. Die in dieser Norm beschriebene Gerätekombination für Verteilungsstationen (en: Compact Equipment Assembly for Distribution Substation – CEADS) wird als Einzelprodukt geprüft, mit einer Seriennummer versehen und hat eine gemeinsame Dokumentation. Derartige Einrichtungen werden als eine Transport¬einheit geliefert. Jedoch können Hersteller und Anwender vereinbaren, die Transporteinheit zu zerlegen, falls der Transport der kompletten CAEDS nicht durchführbar ist. In diesem Fall müssen geeignete Funktions-prüfungen am Aufstellort durchgeführt werden. ANMERKUNG 1 Wenn die Funktionseinheiten von einander unabhängig sind, hat jede Einheit eine eigene Serien-nummer. Eine CEADS ist keine fabrikfertige (nach EN 62271 202) oder nicht-fabrikfertige (nach EN 61936-1) Verteilungsstation. CEADS sind jedoch dazu vorgesehen, dass sie Teil einer Verteilungsstation werden, in der die HS-Betriebsmittel, der Leistungstransformator und die NS-Betriebsmittel bestimmungsgemäß mitein-ander verbunden sind (siehe Anhang C, in dem auch die Entstehung und die Bauarten von CEADS erläutert werden). Die Funktionen einer CEADS sind: – Schalten und Steuern für den Betrieb der HS-Seite sowie Schutz für die HS/NS-Transformatoreinheit; – HS/NS-Umspannung (Transformator); – Schalten und Steuern für den Betrieb und den Schutz der NS-Abzweige. Wesentliche Bestimmungen dieser Norm gelten jedoch auch für Bauformen, bei denen nicht alle genannten Funktionen vorhanden sind (z. B. Einrichtungen, die nur HS/NS-Umspannen, Schalten oder Steuern und Schützen der NS-Schalteinheit). CEADS sind für Anlagen innerhalb abgeschlossener elektrischer Betriebsstätten (siehe 1.3.3) in Gebäuden oder im Freien vorgesehen, die Teil einer Verteilungsstation sind und hauptsächlich in einem öffentlichen Verteilungsnetz eingesetzt werden. Für industrielle Anwendungen, wie z. B. in Fabriken, ist eine Errichtung von CEADS außerhalb geschlosse¬ner elektrischer Betriebsstätten erlaubt, vorausgesetzt dass Sicherheitsbestimmungen durch zusätzliche Maßnahmen erfüllt werden, die an den Aufstellort angepasst sind; dafür ist der Planer der Anlage verant-wortlich. Die vorliegende Norm berücksichtigt die mögliche Wechselwirkung zwischen den Funktionseinheiten, wenn sie eng nebeneinander aufgebaut und miteinander verbunden sind, um eine typgeprüfte Gerätekombination zu bilden und definiert Bemessungswerte, besondere Konstruktions- und Bauanforderungen sowie Prüf-verfahren für diese Gerätekombination. ANMERKUNG 2 Wechselwirkung ist der Einfluss einer Funktion der Einrichtung auf eine andere (z. B. elektrische, mechanische und thermische Beanspruchung). ANMERKUNG 3 Im Sinne dieser Norm wird ein selbstgeschützter Transformator nicht als CEADS betrachtet, sondern als Funktionseinheit, die nach ihrer eigenen Produktnorm EN 60076 13 konstruiert und typgeprüft ist.
Ensembles Compacts d’Equipement pour Postes de Distribution (ECEPD)
Cette Norme Européenne spécifie les conditions de service, les caractéristiques assignées, les exigences structurelles générales et les méthodes d'essai applicables à l’ensemble préfabriqué d’unités fonctionnelles principales dûment interconnectées d’un Poste de Distribution HT/BT pour courant alternatif de tensions de service assignées supérieures à 1 kV et inférieures ou égales à 52 kV côté HT, de fréquence de service 50 Hz. Cet ensemble est connecté par câbles au réseau. Cet Ensemble Compact d’Equipement pour Postes de Distribution (ECEPD) tel que défini dans cette norme est conçu et testé pour être un produit unique avec un numéro de série unique et un ensemble de documentation. Un tel équipement est livré en une seule unité de transport. Pour des raisons pratiques, le constructeur et l’utilisateur peuvent s’accorder pour transporter l’ensemble démonté si le transport ou l’installation du ECEPD complet n’est pas possible. Dans ce cas des essais de vérification appropriés doivent être réalisés sur le site d’installation. Note 1 Lorsque les unités fonctionnelles sont indépendantes, chaque unité fonctionnelle aura aussi son propre numéro de série. Un ECEPD n’est pas un Poste de Distribution, qu’il soit préfabriqué (couvert par la EN 62271-202) ou non (couvert par la EN 61936-1). Cependant un ECEPD est destiné à devenir une partie d’un Poste de Distribution en regroupant l’équipement HT, le transformateur de puissance et l’équipement BT dûment interconnectés (voir l’Annexe C, qui explique aussi l’origine et les types d’ECEPD). Les fonctions d’un ECEPD sont: - la connexion et la commande pour les opérations côté HT et la protection de l’unité fonctionnelle transformateur HT/BT; - la transformation HT/BT; - la connexion et la commande pour l’exploitation et la protection des départs BT. Cependant les dispositions significatives de cette norme sont aussi applicables à des conceptions pour lesquelles ces fonctions ne sont pas toutes présentes (par exemple équipement comprenant seulement les fonctions transformation HT/BT et connexion et commande pour l’exploitation et la protection des départs BT). Pour les réseaux publics de distribution, les ECEPD sont destinés à être installés dans un local de service électrique fermé, en intérieur ou en extérieur (voir Définition 1.3.3), intégré à un Poste de Distribution. Pour les applications industrielles, comme les usines, l’installation d’un ECEPD en dehors d’un local de service électrique fermé peut être autorisée dans la mesure où les règlements de sécurité sont respectés grâce à l’adoption de dispositions additionnelles sur le site d’installation sous la responsabilité du concepteur de l’installation. Cette norme prend en considération les interactions potentielles entre les unités fonctionnelles lorsqu’elles sont installées à proximité les unes des autres et interconnectées pour former un ensemble d’équipement testé, et définit les caractéristiques assignées, les exigences particulières de conception et de construction et les méthodes d'essai pour cet ensemble d’équipement. NOTE 2 L’interaction est l’influence d’une unité fonctionnelle de l’équipement sur une autre (c.-à-d. contraintes électriques mécaniques et thermiques). NOTE 3 Dans le cadre de la présente norme un transformateur auto-protégé n’est pas considéré comme un ECEPD, mais comme une unité fonctionnelle conçue et testée selon sa propre norme de produit EN 60076 13.

Introduction
The objective of this standard is to respond to the currently in use compact assemblies that perform the
main electrical functions of a distribution substation. Numerous arrangements are possible and this
standard provides guidance on basic types of assemblies, which might be envisaged (see Annex C).
As there are potential interactions between devices within such assemblies, it is necessary to consider
the standardisation requirements for the assembly in its entirety.
---------------------- Page: 8 ----------------------
SIST EN 50532:2010

1 General
1.1 Scope
This European Standard specifies the service conditions, rated characteristics, general structural
requirements and test methods of the prefabricated assembly of the main electrical functional units of a
HV/LV Distribution Substation, duly interconnected, for alternating current of rated operating voltages
above 1 kV and up to and including 52 kV on the HV side, service frequency 50 Hz. This assembly is to
be cable-connected to the network.
This Compact Equipment Assembly for Distribution Substation (CEADS) as defined in this standard is
designed and tested to be a single product with a single serial number and one set of documentation.
Such equipment is delivered as single transport unit. For practical reasons manufacturer and user can
agree to transport the unit dismantled if transport or installation of the complete CEADS is not possible. In
that case suitable verification tests shall be carried out at the installation site.
Note 1: Where the functional units are independent each functional unit will also have its own serial number.
A CEADS is not a Distribution Substation, either prefabricated (covered by EN 62271-202) or not
(covered by EN 61936-1). However CEADS is intended to become part of a Distribution Substation
assembling the HV equipment, the power transformer and the LV equipment duly interconnected (see
Annex C, which also explains the origin and types of CEADS).
The functions of a CEADS are:
– switching and control for the operation of the HV side and protection of the HV/LV transformer
functional unit;
– HV/LV transformation;
– switching and control for the operation and protection of the LV feeders.
However relevant provisions of this standard are also applicable to designs where not all of these
functions exist (e.g. equipment comprising only HV/LV transformation and switching and control for the
operation and protection of the LV feeder functions).
For public distribution networks, CEADS are intended for installation within an indoor or outdoor closed
electrical operating area (see Definition 1.3.3) forming part of a Distribution Substation.
For industrial applications, such as factories, installation of CEADS outside a closed electrical operating
area may be allowed provided that safety regulations are fulfilled by additional measures adopted at the
installation site under the responsibility of the designer of the installation.
This standard considers the potential interaction between the individual functions when closely installed
and interconnected to form a type tested assembly and defines ratings, particular design and construction
requirements and test procedures for this assembly.
NOTE 2 Interaction is the influence of one functional units of the equipment on another (i.e. electrical mechanical and thermal
stresses).
NOTE 3 For the purpose of this standard a self-protected transformer is considered not as a CEADS, but as a functional unit,
designed and type tested to its own product standard EN 60076-13.
