标准摘要
[中文适用范围]: 本部分 IEC 62561 规定了用于雷电防护系统的隔离火花间隙 (ISGs) 的要求和测试。 ISGs 可用于将雷电防护系统间接连接到其他附近的金属部件,在功能原因不允许直接连接的情况下。 典型应用包括连接到: - 电力设施的接地系统, - 电信系统的接地系统, - 电压操作、接地故障断路器的辅助接地电极, - 电力和直流铁路的轨道接地电极, - 实验室的测量接地电极, - 具有阴极保护和杂散电流系统的设施, - 低压架空电缆的进线杆, - 绕过管道的绝缘法兰和绝缘接头。 不包括后续电流发生的应用。 注1:在 CENELEC 成员国,爆炸性环境组件的测试要求在 CLC/TS 50703-2 中规定。 注2:本文件不包括针对爆炸性环境(如 IEC 60079-10 系列所定义)组件的测试。 [外文原描述]: IEC 62561-3:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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.
