标准摘要
[中文适用范围]： 本部分IEC 62271适用于额定电压高于52kV、工作频率为50Hz和60Hz的高压交流隔离开关断路器。本文件确定了IEC 62271-1、IEC 62271-100和IEC 62271-102的适用要求，并给出了这些设备的特定附加要求。本文件涵盖通过安装在单一外壳中的触点同时执行断路器和隔离开关功能的单一开关设备，其中断路器触点在断开位置满足或有助于隔离开关功能的隔离要求。由于各功能要求之间存在相互作用，考虑要求的标准化非常重要。本文件详细规定了隔离开关断路器的要求，指出了这些要求与独立断路器和隔离开关要求的不同之处。 [外文原描述]： IEC 62271-108:2020 applies to high-voltage alternating current disconnecting circuit-breakers for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 52 kV. This second edition cancels and replaces the first edition published in 2005. This edition contains the following significant technical changes with respect to the previous edition: - The document has been restructured according to IEC 62271-1:2017. - The document has been adapted to some of the changes introduced in IEC 62271-100:–[1]. - The document has been adapted to some of the changes introduced in IEC 62271-102:2018. - References have been reviewed and updated. - Some definitions have been reviewed and adapted to the latest IEV editions. - Rated static terminal load and static terminal load test have been removed and a design requirement for static mechanical loads has been included. - Additional type tests for auxiliary and control circuits have been included. - X-radiation test procedure for vacuum interrupters has been included. - Type test for testing of interlocking device and type test for testing of temporary mechanical locking devices have been included. - Special requirements for making and breaking tests on class E2 disconnecting circuit-breakers have been removed. [1] Under preparation. Stage at the time of publication: IEC CDV 62271-100:2020.
