标准摘要
[中文适用范围]： IEC 62271的本部分适用于设计用于室内和室外安装以及在电压为550 kV及以上的系统上以50 Hz和60 Hz服务频率运行的交流高速接地开关。本标准所述的高速接地开关用于熄灭断路器清除输电线路故障后剩余的二次电弧。 [外文原描述]： IEC 62271-112:2013 applies to a.c. high-speed earthing switches designed for indoor and outdoor installation and for operation at service frequencies of 50 Hz and 60 Hz on systems having voltages of 550 kV and above. High-speed earthing switches described in this standard are intended to extinguish the secondary arc remaining after clearing faults on transmission lines by the circuit-breakers. This publication is to be read in conjunction with IEC 62271-1:2007 .
