CEI EN 62271-205

BILINGUAL

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.

It is not possible to define all potential arrangements of
compact switchgear assemblies however four examples are shown for
information in Annex A.

These compact switchgear assemblies are for indoor and/or
outdoor installations in systems having rated voltages above 52 kV
and service frequencies of 50 Hz and 60 Hz.

This standard covers the influence on performance of the
interactions between devices within compact switchgear assemblies
and defines ratings and test procedures for these assemblies.

IEC 62271-1 is applicable if not stated otherwise.

This standard does not apply to switchgear assemblies consisting
solely of GIS which are covered by IEC 62271-203.
