标准摘要
[中文适用范围]： IEC 62271-1:2007 的第 1.1 条不适用，并替换如下： IEC 62271 的本部分适用于额定电压高于 52 kV@、具有接通和分断电流额定值@的户内三极交流开关。和室外安装@，额定频率高达 60 Hz（含）。本标准也适用于这些开关的操作装置及其辅助设备。注 1：本标准涵盖气体绝缘开关设备的开关。注 2：IEC 62271-102 还涵盖具有隔离功能且称为隔离开关的开关。 注 3：本标准不涵盖接地开关。 IEC 62271-102 涵盖了构成开关组成部分的接地开关。该标准的主要目标是制定输配电系统中使用的开关的要求。用于此应用的通用开关被设计为符合以下服务应用： ?C 连续承载额定正常电流； ?C 承载规定时间内的短路电流； ?主要有源负载的C切换； ?空载变压器的C切换； ?C 切换空载电缆@架空线路或母线的充电电流；闭环电路的C切换； ?C产生短路电流。该标准的另一个目标是制定输配电系统中使用的有限用途和特殊用途交换机的要求。有限用途交换机符合上述一项或多项服务应用。专用开关可符合上述一种或多种服务应用，并且此外还适用于以下一种或多种应用： ?C 开关单个电容器组； ?C 切换背靠背电容器组； ?C 切换并联电抗器，包括从变压器初级侧切换的二次或三次电抗器； ?需要增加操作周期数的C应用； ?C 在中性线非有效接地系统中接地故障条件下的切换。 [外文原描述]： IEC 62271-104:2015 is applicable to three-pole alternating current switches for rated voltages higher than 52 kV, 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. This second edition replaces and cancels the first edition published in 2009 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the title was changed such that the voltage range now is >52 kV instead of ≥52 kV; - the references have been updated; - the comments in 17A/1063/RVC have been addressed. This publication is to be read in conjunction with IEC 62271-1:2007 , IEC 62271-100:2008 , IEC 62271-102:2001 and IEC 62271-110:2012 .
