高压架空线路用复合悬式和张力绝缘子交流电压大于1000V或直流电压大于1500V的定义、测试方法及接受条件

[中文适用范围]： IEC61109:2025 CMV 包含官方标准及其注释版本。注释版本为您提供了一种快速简便的方法来比较 IEC 61109:2025 版本 3.0 和之前的 IEC 61109:2008 版本 2.0 之间的所有更改。此外，还提供了来自 IEC TC 36 专家的评论，以解释最相关更改的原因，或澄清任何部分内容。IEC 61109:2025 适用于架空线路的复合绝缘子，该绝缘子由树脂基基质中的纤维（通常是玻璃）组成的承重圆柱形绝缘实心芯、由聚合物材料制成的外壳（围绕绝缘芯）和永久固定在绝缘芯上的金属端配件组成。本文件涵盖的复合绝缘子旨在用作悬挂/张力线绝缘子，但这些绝缘子偶尔会受到压缩或弯曲，例如在用作相间隔物时。此类负载的指导在附录 C 中概述。本文件的目的是： - 定义所使用的术语， - 指定测试方法， - 指定验收标准。第三版取消并取代了 2008 年发布的第二版。此版本构成技术修订。此版本与前一版相比包括以下重大技术变化： - 将本文件扩展为适用于交流和直流系统； - 修改第 3 章“术语、定义和缩写”； - 从本文件中删除第 7 章“混合绝缘子”； - 修改最近纳入 IEC 62217 的测试程序（疏水性转移试验、应力腐蚀、带外壳的芯线水扩散试验）； - 修改环境条件； - 修改测试分类并包括接口的相关性； - 澄清和修改确定需要重复设计和型式试验的参数； - 修订表 1； - 修订电气型式试验； - 修订样品试验的重新试验程序- 增加了有关交流电场控制的新附录 D； - 增加了有关复合绝缘子组装典型草图的新附录 E； - 增加了有关芯线和外壳之间粘附力的机械评估的新附录 F； - 增加了有关直流应用设计和型式试验适用性的新附录 G。 [外文原描述]： IEC61109:2025 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61109:2025 edition 3.0 and the previous IEC 61109:2008 edition 2.0. Furthermore, comments from IEC TC 36 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 61109:2025 applies to composite insulators for overhead lines consisting of a load-bearing cylindrical insulating solid core consisting of fibres - usually glass - in a resin-based matrix, a housing (surrounding the insulating core) made of polymeric material and metal end fittings permanently attached to the insulating core. Composite insulators covered by this document are intended for use as suspension/tension line insulators, but these insulators could occasionally be subjected to compression or bending, for example when used as interphase-spacers. Guidance on such loads is outlined in Annex C. The object of this document is to: - define the terms used, - specify test methods, - specify acceptance criteria. This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - extension of this document to apply both to AC and DC systems; - modifications of Clause 3, Terms, definitions and abbreviations; - removal of Clause 7, Hybrid insulators, from this document; - modifications of tests procedures recently included in IEC 62217 (hydrophobicity transfer test, stress corrosion, water diffusion test on the core with housing); - modifications on environmental conditions; - modifications on classification of tests and include the relevance of the interfaces; - clarification and modification of the parameters determining the need to repeat design and type tests; - revision of Table 1; - revision of electrical type tests; - revision of re-testing procedure of sample test; - addition of a new Annex D on electric field control for AC; - addition of a new Annex E on typical sketch for composite insulators assembly; - addition of a new Annex F on mechanical evaluation of the adhesion between core and housing; - addition of a new Annex G on applicability of design- and type tests for DC applications.
