新的！IEC 60826:2017作为IEC 60826:2017 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。 IEC 60826:2017:规定了源自基于可靠性的设计原则的架空线路的载荷和强度要求。这些要求适用于45 kV及以上的线路，但也可适用于标称电压较低的线路。 本文件还提供了一个框架，用于制定处理架空输电线路的国家标准，使用可靠性概念并采用概率或半概率方法。这些国家标准将需要为本标准的使用和应用建立当地的气候数据，此外还有其他国家的数据-具体的。 尽管本标准中的设计标准适用于新线路，但许多概念可用于解决现有线路翻新、升级和升级的设计和可靠性要求。 本文件不包括线路组件的详细设计，如支架、基础、导体或绝缘子串。 这第四版取消并取代了2003年出版的第三版。它构成技术修订。 与上一版相比，主要技术变化如下: 通过删除许多信息性附件和理论细节，本标准得到了进一步简化，这些附件和理论细节现在可以在CIGRE技术手册178中找到，并在标准文本中根据需要引用。还进行了许多修订，以反映用户在应用该标准时的经验，以及有关由于悬崖导致风速放大的信息。有关结冰数据的附件也已利用CIGRE的新工作进行了更新。 关键词:架空线路架空输电线路可靠性能源

NEW! IEC 60826:2017 is available as IEC 60826:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60826:2017: specifies the loading and strength requirements of overhead lines derived from reliability-based design principles. These requirements apply to lines 45 kV and above, but can also be applied to lines with a lower nominal voltage.
This document also provides a framework for the preparation of national standards dealing with overhead transmission lines, using reliability concepts and employing probabilistic or semi-probabilistic methods. These national standards will need to establish the local climatic data for the use and application of this standard, in addition to other data that are country- specific.
Although the design criteria in this standard apply to new lines, many concepts can be used to address the design and reliability requirements for refurbishment, upgrading and uprating of existing lines.
This document does not cover the detailed design of line components such as supports, foundations, conductors or insulators strings.
This fourth edition cancels and replaces the third edition published in 2003. It constitutes a technical revision.
The main technical changes with regard to the previous edition are as follows:
This standard has been further simplified by removing many informative annexes and theoretical details that can now be found in CIGRE Technical Brochure 178 and referred to as needed in the text of the standard. Many revisions have also been made that reflect the users experience in the application of this standard, together with information about amplification of wind speed due to escarpments. The annexes dealing with icing data have also been updated using new work by CIGRE.
