+AMD1:2024 CSV 高压开关设备和控制设备 第200部分：额定电压1kV以上至52kV（含）的交流金属封闭开关设备和控制设备

[中文适用范围]： 本部分 IEC 62271 适用于预制金属封闭开关设备和控制设备组件，设计用于：- 交流电流；- 额定电压高于 1kV 且不超过 52kV；- 工作频率不超过 60Hz；- 室内和室外安装。该组件可以包括空气绝缘和/或流体填充的隔间。对于安装在金属封闭开关设备和控制设备中的组件，本文件补充或在某些情况下取代了各个产品标准中规定的要求。金属封闭开关设备和控制设备内的组件列表不限于本文件中明确引用的那些。 [外文原描述]： IEC 62271-200:2021+AMD1:2024 CSV is applicable to prefabricated metal‑enclosed switchgear and controlgear assemblies designed for: - 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 explanatory flowchart (Annex D); j) examples not covered by the IAC test are transferred from Clause 6 to 9.103; k) the term "assembly" is defined in Clause 3 and used as synonym for "metal-enclosed switchgear and controlgear" in this document; l) "metallic" is replaced by "metal" where applicable; m) 6.105 is now covered by 7.7; n) a 1 s rule was introduced for Criterion 4 during IAC tests regarding hot gases versus glowing particles as cause of ignition; o) a more precise description of internal arc tests for switchgear with protrusions is given in Annex A.
