标准摘要
[中文适用范围]： IEC 62271的本部分适用于设计为室内或室外安装并在电压高于1 000 V的系统上以50 Hz和60 Hz频率运行的交流断路器。它仅适用于用于以下用途的三极断路器：用于三相系统，单极断路器用于单相系统。用于单相系统和频率低于 50 Hz 的两极断路器须经制造商和用户双方同意。本标准也适用于断路器的操作装置及其辅助设备。然而，对于具有独立手动操作合闸机构的断路器，如果不包括在本标准中，则无法规定额定短路关合电流，并且出于安全考虑，这种独立手动操作可能会令人反感。 [外文原描述]： IEC 62271-100:2008 is applicable to a.c. circuit-breakers designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V. It is only applicable to three-pole circuit-breakers for use in three-phase systems and single-pole circuit-breakers for use in single-phase systems. This second edition cancels and replaces the first edition published in 2001 and its amendments 1 (2002) and 2 (2006). It also cancels and replaces IEC 61633 and IEC 62271-308. The main changes with respect to the previous edition are listed below: - the introduction of harmonised (IEC and IEEE) TRV waveshapes for rated voltages of 100 kV and above (amendment 1 to the first edition); - the introduction of cable and line systems with their associated TRVs for rated voltages below 100 kV (amendment 2 to the first edition); - the inclusion of IEC 61633 and IEC 62271-308. This standard shall be read in conjunction with IEC 62271-1, first edition, published in 2007.
