标准摘要
[中文适用范围]： IEC 60099的这一部分不是强制性标准，而是为标称电压高于1 kV的三相系统中使用的避雷器的选择和应用提供信息、指导和建议。它适用于IEC 60099-4定义的无间隙金属氧化物避雷器、IEC 60099-6定义的包含串联和并联间隙结构的额定电压52 kV及以下的避雷器以及具有外部串联间隙的金属氧化物避雷器适用于 IEC 60099-8 中定义的架空输电和配电线路 (EGLA)。在附录 H 中，讨论了有关旧型 SiC 间隙避雷器的一些方面。 [外文原描述]： IEC 60099-5:2013 is not a mandatory standard but provides information, guidance, and recommendations for the selection and application of surge arresters to be used in three-phase systems with nominal voltages above 1 kV. It applies to gapless metal-oxide surge arresters as defined in IEC 60099-4, to surge arresters containing both series and parallel gapped structure - rated 52 kV and less as defined in IEC 60099-6 and metal-oxide surge arresters with external series gap for overhead transmission and distribution lines (EGLA) as defined in IEC 60099-8. In Annex H, some aspects regarding the old type of SiC gapped arresters are discussed. This second edition cancels and replaces the first edition published in 1996 and its amendment 1 published in 1999. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - Expanded discussion of different types of arresters and their application, including additions of discussion on transmission of line arresters, arresters for shunt capacitor switching arresters for series capacitor protection, application of arresters between phases connecting arresters in parallel; - Addition of section on asset management, including: managing surge arresters in the power grid, arrester maintenance, significantly expanded discussion of performance diagnostic tools, end-of-life considerations; - New annexes dealing with: arrester modelling for system studies, example of data needed for specifying arresters. Key words: selection and application of surge arrestors, nominal voltages above 1 kV
