标准摘要
[中文适用范围]： 本国际标准适用于户内和户外安装的额定电压52kV以上交流开关设备组件，包括其刚性连接到地面的支撑结构，不包括带电罐式断路器的抗震鉴定。开关设备组件通常具有低重心，例如气体绝缘开关设备(GIS)。对于重力水平较高的开关设备，例如带电罐式断路器，IEC 62271-300 适用。如果开关设备组件不是地面安装的，例如在建筑物中，则应用条件取决于用户和制造商之间的协议。开关设备组件的抗震鉴定考虑了直接安装或作为单独结构安装的任何辅助和控制设备。本标准提供了额定电压高于 52 kV 的地面安装开关设备组件的抗震鉴定程序。开关设备组件的抗震鉴定仅根据要求进行。该标准规定了地震严重程度，并提供了可用于证明需要抗震鉴定的高压开关设备组件性能的方法选择。最终的地震分析应假设开关柜安装在坚固的地面上进行。 [外文原描述]： This International Standard applies to switchgear assemblies for alternating current of rated voltages above 52 kV for indoor and outdoor installations, including their supporting structure rigidly connected to the ground, and does not cover the seismic qualification of live tank circuit breakers. Switchgear assemblies do have typically low centers of gravity, e.g. gas-insulated switchgear (GIS). This first edition of IEC 62271-207 cancels and replaces the first edition of IEC 62271-2 and constitutes a technical revision. The change from IEC 62271-2 is as follows: -the minimum voltage rating was changed from 72,5 kV to above 52 kV
