标准摘要
[中文适用范围]： 本标准适用于雷电保护系统（LPS）中使用的隔离火花间隙（ISGs）。它规定了ISGs的设计、测试和性能要求，这些组件对于确保LPS的安全性和可靠性至关重要。ISGs旨在隔离电气系统免受雷击引起的浪涌，防止敏感设备受损并确保不间断运行。本标准为制造商、安装人员和用户提供了确保ISGs符合必要安全和性能标准的指南。 [外文原描述]： IEC 62561-3:2023 specifies the requirements and tests for isolating spark gaps (ISGs) for lightning protection systems. ISGs can be used to indirectly bond a lightning protection system to other nearby metalwork where a direct bond is not permissible for functional reasons. This third edition cancels and replaces the second edition, published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition. a) alignment with the latest edition of ISO 22479 relating to humid sulphurous atmosphere treatment; b) addition of a new normative Annex D for the applicability of previous tests.
