标准摘要
[中文适用范围]: 本部分 IEC 62271 规定了额定电压高于 1 kV 且不超过 52 kV 的预制固体绝缘封闭式开关设备和控制设备在室内安装及频率不超过 60 Hz 下的要求。进入开关设备和控制设备的权限仅限于授权人员。注 1:对于本文件的使用,高压(IEC 60050-601:1985, 601-01-27)是指额定电压高于 1000 V。然而,中压(IEC 60050-601:1985, 601-01-28)通常用于电压高于 1 kV 且一般适用于不超过 52 kV 的配电系统;参见参考文献 [1]。注 2:虽然主要适用于三相系统,但本标准也可用于单相或两相系统。 [外文原描述]: IEC 62271-201:2014 specifies requirements for prefabricated solid-insulation enclosed switchgear and controlgear for alternating current of rated voltages above 1 kV and up to and including 52 kV for indoor installation and for service frequencies up to and including 60 Hz. This second edition cancels and replaces the first edition, published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) apart from updating with the second edition of IEC 62271-200 (issued in 2011), definitions, classifications and testing procedures have been specified more precisely; b) access to the solid-insulation enclosed switchgear and controlgear is now restricted to authorized personnel only. This implies that "accessibility class B" (public access) has been deleted throughout the document; c) the term "protection category" has been introduced to replace the term "protection grade" (PA, PB1 and PB2). This publication is to be read in conjunction with IEC 62271-1:2007 .
