标准摘要
[中文适用范围]： IEC 62271的本部分规定了用于额定电压1kV以上且52kV以下、使用频率60Hz以下的交流电的金属封闭柱上开关设备装置的内部电弧分级要求。本文件适用于三相@两相和单相设备。外壳可以包括固定和可拆卸的部件，并且可以填充流体（液体或气体）以提供绝缘。注：对于本文件的使用，高压 (IEC 60050-601:1985@ 601-01-27) 是指额定电压高于 1 000 V。然而，中压 (IEC 60050-601:1985@ 601-01-28) )常用于电压高于1 kV的配电系统，一般适用于52 kV及以下；参见参考书目[1]。本文件并不排除其他设备可以包含在同一外壳中。在这种情况下，应考虑该设备对开关设备和控制设备的任何可能影响。 [外文原描述]： IEC 62271-214:2019 specifies requirements for internal arc classification of metal-enclosed pole-mounted switchgear installations used for alternating current with rated voltages above 1 kV and up to and including 52 kV with service frequencies up to and including 60 Hz. This document is applicable to three-phase, two-phase and single phase equipment. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation.
