IEC 62271-200:2021(E) is applicable to prefabricated metal enclosed switchgear and controlgear assemblies designed for:全文を表示する
alternating current;
rated voltages above 1 kV and up to and including 52 kV;
service frequencies up to and including 60 Hz;
indoor and outdoor installation.
The assembly can include air-insulated and/or fluid-filled compartments.
This third edition cancels and replaces the second edition published in 2011. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) clause numbering aligned with IEC 62271 1:2017, including the adoption of the subclause names of Clause 3;
b) in Clause 3 specific definitions are added for ""in service"", ""normal operating condition"" and ""normal use"";
c) internal arc testing on pole-mounted switchgear is taken out of this document, as it is now covered by the specific standard IEC 62271 214:2019;
d) a more precise description of earthing circuit is given with the inclusion of ratings and test requirements;
e) number of mechanical tests on interlocks is reduced for type testing; a more precise description of forces to apply during type testing is given (refer to 7.102);
f) resistance measuring on main circuit is only needed before continuous current tests (as reference for routine tests) and no longer needed after this continuous current test. Rationale for this deletion is that this measured resistance does not mean anything; as the temperature rise test was just finished, a new temperature rise test will not give new information;
g) IEC 62271-100:2021, IEC 62271-103:2021, IEC 62271-105:2021 and IEC 62271-106:2021 are referred to in the document;
h) IEC 62271 107:2019 and IEC IEEE 62271 37 013:2015 are also considered in 7.101.2;
i) a more precise description of LSC category is given with the inclusion of an explana
