les procédures de manipulation des alternatives au SF₆, utilisés pour l'isolation et/ou la commutation, sont ajoutées;
les principaux articles sont indépendants du type de gaz;
pour chaque gaz, une annexe distincte présente les informations spécifiques au gaz, les procédures de manipulation, les mesures de sécurité, etc.;
les informations relatives au SF₆ (ancienne Annexe E) et aux effets sur l'environnement du SF₆ et de ses mélanges (ancienne Annexe F) ont été déplacées vers l'IEC 60376;
les informations relatives aux produits de décomposition du SF₆ et de ses mélanges (ancienne Annexe G), la procédure d'évaluation des effets potentiels sur la santé des produits de décomposition du SF₆ et de ses mélanges (ancienne Annexe H) et la régénération cryogénique du SF₆ (ancienne Annexe I) ont été déplacées vers l'IEC 60480.

IEC 62271-205:2008

Tue, 05 Nov 2024 19:42:38 +0000

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.

7.3: Changed the requirement for radio interference voltage to a rated voltage level of 245 kV and above, instead of 123 kV and above. This change is based on reported positive test and service experience of utility representatives in the maintenance team of this standard.
7.5.6, Table 14:
a. Introduced the distinction of parts in “OG” (oxidizing gas) or in “NOG” (not oxidizing gas) replacing the former “air” and “SF6”;
b. Increased the allowable temperature rise for some parts in groups 1 and 2 of Table 14 according to IEC TR 60943;

IEC 62271-104:2009 applies to three-pole alternating current switches for rated voltages 52 kV and above, having making and breaking current ratings, for indoor and outdoor installations, and for rated frequencies up to and including 60 Hz. This standard is also applicable to the operating devices of these switches and to their auxiliary equipment. The main object of this standard is to establish requirements for switches used in transmission and distribution systems. General-purpose switches for this application are designed to comply with the following service applications:
– carrying rated normal current continuously;
– carrying short-circuit currents for a specified time;
– switching of mainly active loads;
– switching of no-load transformers;
– switching of the charging current of unloaded cables, overhead lines or busbars;
– switching of closed-loop circuits;
– making short-circuit currents.
A further object of this standard is to establish requirements for limited-purpose and special- purpose switches used in transmission and distribution systems. Limited-purpose switches shall comply with one or more of the service applications indicated above. Special-purpose switches may comply with one or more of the service applications indicated above and, in addition, shall be suitable for one or more of the following applications:
– switching single capacitor banks;
– switching back-to-back capacitor banks;
– switching shunt reactors including secondary or tertiary reactors switched from the primary side of the transformer;
– applications requiring an increased number of operating cycles;
– switching under earth fault conditions in non-effectively earthed neutral systems.
This standard cancels and replaces IEC 60265-2:1988. The major changes with respect to IEC 60265-2 are as follows:
– alignment with IEC 62271-1 and IEC 62271-100;
– requirements for capacitive current switching aligned with those in IEC 62271-100: classes C1 and C2 are introduced.

This publication is to be read in conjunction with IEC 62271-1:2007, IEC 62271-100:2008, IEC 62271-102:2001 and IEC 62271-110:2005.
