(Main)High-voltage switchgear and controlgear - Part 205: Compact switchgear assemblies for rated voltages above 52 kV
High-voltage switchgear and controlgear - Part 205: Compact switchgear assemblies for rated voltages above 52 kV
This part of IEC 62271 applies to compact switchgear assemblies consisting of at least one switching device directly connected to, or sharing components with, one or more other devices such that there is an interaction between the functions of the individual devices. Such assemblies are made up of devices defined in 1.101 and are designed, tested and supplied for use as a single unit. The interaction between devices may be due to proximity, sharing of components or a combination of both. The assemblies may contain components of air insulated switchgear (AIS) only or a combination of AIS and gas insulated switchgear (GIS), so called mixed technology switchgear (MTS) and may be delivered entirely prefabricated or partially assembled.

Appareillage à haute tension - Partie 205: Ensembles d'appareillages compacts de tensions assignées supérieures à 52 kV
La présente partie de la CEI 62271 s'applique aux ensembles d'appareillages compacts comprenant au moins un appareil de connexion directement connecté à, ou partageant des composants avec, un ou plusieurs appareils tel(s) qu'il existe une interaction entre les fonctions des appareils individuels. De tels ensembles sont constitués des appareils définis en 1.101, ils sont conçus, essayés et fournis pour être utilisés comme une seule unité. L'interaction entre les appareils peut être due à la proximité, au partage de composants ou à une combinaison des deux. Les ensembles peuvent comprendre des composants d'appareillages isolés à l'air (Air Insulated Switchgear - AIS) uniquement ou une combinaison d'AIS et d'appareillages à isolation gazeuse (Gas Insulated Switchgear - GIS), désignée sous le terme appareillage à technologie mixte (Mixed Technology Switchgear - MTS), ils peuvent être livrés entièrement préfabriqués ou partiellement assemblés.

submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 62271-205 on
2008-03-01.
This standard is to be used in conjunction with EN 62271-1:2007, to which it refers and which is
applicable, unless otherwise specified. In order to simplify the indication of corresponding requirements,
the same numbering of clauses and subclauses is used as in EN 62271-1. Amendments to these clauses
and subclauses are given under the same numbering, whilst additional subclauses are numbered
from 101.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2008-12-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2011-03-01
Annexes ZA and ZB have been added by CENELEC.

A-deviation: National deviation due to regulations, the alteration of which is for the time being outside the
competence of the CENELEC national member.
This European Standard does not fall under any Directive of the EC.

- (I.S.P.E.S.L. Rules, 95 revision: VSR.8.B.1; VSR.8.B.2; M.15.D.2)
Italian laws apply to gas pressurized enclosures made of both insulating and metallic
materials with a capacity of 25 litres or above, a design pressure higher than 0,05 kg/cm
and a temperature range: -25 °C/+100 °C (only for insulating materials).
Moreover the manufacturer of any electrical equipment which comprehends gas
pressurized enclosures must submit the design of the pressurized enclosures itself to a
proper legal Authority indicating the stresses and the loads which have any influence on
the design itself. For each of the stresses the manufacturer must indicate the design
values and the relevant computations.
- (I.S.P.E.S.L. Rules, 95 revision: VSR.8.B.1 and M.15.D.3. Table I for porcelain)
Only the use of porcelain type .A or S. (Aluminous or Siliceous) is permitted.
- (I.S.P.E.S.L. Rules, 95 revision: VSR.8.B.1 Clause 2)
The type test shall be performed in the presence of the Authority Supervisor.
- (I.S.P.E.S.L. Rules, 95 revision: VSR.8.B.2 Clause 2; M.15.D.4)
An additional pressure test shall be performed on a complete pressurized enclosure. This
has to withstand 1,5 times the design pressure without failure for five minutes.
Temperature cycles test and electrical test shall be made; after these tests shall be
carried out consecutively the pressure test at pressure p ≥ 4,25 times the design
pressure.
- (I.S.P.E.S.L. Rules, 95 revision: VSR.8.B.1 Subclause 4.1.2)
For a homogeneous batch of 100 pieces max., one hollow insulator shall be subjected to
the failure test with a pressure 4,25 times the design pressure.
- (Italian pressure vessel code for electrical switchgear DM 1 December 1980 and DM
10 September 1981 published in Gazzetta Ufficiale n° 285 dated 16.10.1981)
For metal-enclosed switchgear and controlgear containing gas-filled compartments, the
design pressure is limited to a maximum of 0,5 bar (gauge) and the volume is limited to a
maximum of 2 m³. Gas filled compartments having a design pressure exceeding 0,5 bar
(gauge) or a volume exceeding 2 m³ shall be designed according to the Italian pressure
vessel code for electrical switchgear.
