标准摘要
[中文适用范围]： IEC 62561-2:2025 规定了以下内容的要求和测试方法： - 构成接闪系统和引下线系统的金属导体（除“自然”导体外）； - 构成接地系统的一部分的金属接地电极。 本版为第三版，取消并替代了2018年发布的第二版。本版构成技术修订。与前一版相比，本版包含了以下重大技术变更： a) 新增了本文件中提及的新型导体类型的定义； b) 根据IEC 60068-2-52:2017 对盐雾处理进行了更新； c) 根据ISO 22479:2019 对潮湿硫化气氛处理进行了更新； d) 新增了规范性附录H，用于材料、结构和截面积测试； e) 新增了规范性附录I，用于先前测试的适用性说明； f) 引入了等电位接地网。 [外文原描述]： IEC 62561-2:2025 specifies the requirements and tests for - metallic conductors (other than "natural" conductors) that form part of the air-termination and down-conductor systems, and - metallic earth electrodes that form part of the earth-termination system. This third edition cancels and replaces the second edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) definitions of new conductor types mentioned in this document have been added; b) the document has been updated in line with IEC 60068-2-52:2017 on salt mist treatment; c) the document has been updated in line with ISO 22479:2019 on humid sulphurous atmosphere treatment; d) a new normative Annex H for material, configuration and cross-sectional area test has been introduced; e) a new normative Annex I for applicability of previous tests has been introduced. f) equipotential earth grid has been introduced.
