新的！IEC 60076-11:20 18作为IEC 60076-11:20 18 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 60076-11:20 18适用于干式电力变压器（包括自耦变压器），其设备的最高电压值不超过72.5 kV，并且至少有一个绕组的工作电压大于1.1 kV。本文件不适用于:-气体不是空气的充气干式变压器；-额定值小于5千伏安的单相变压器；-额定值小于15千伏安的多相变压器；-仪器变压器；-启动变压器；-测试变压器；-安装在机车车辆上的牵引变压器；-隔爆型和矿用变压器；-焊接变压器；-电压调节变压器；-需要特别考虑安全性的小型电力变压器。如果上述变压器或其他特殊变压器不存在IEC标准，则本文件可全部或部分适用。？第二版取消并取代了2004年出版的第一版，构成了技术修订。与上一版相比，主要变化如下:-范围扩展至72.5 kV-关于性能的外壳管理-随海拔高度管理介电和热特征-新的气候等级，更好地适应客户的需要-建立地点与环境类别之间的关系-对于火灾行为等级，1000kVA的限制和更稳健的测试过程-地震等级介绍-非晶变压器的建议关键词:干式变压器

NEW!IEC 60076-11:2018 is available as IEC 60076-11:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60076-11:2018 applies to dry-type power transformers (including auto-transformers) having values of highest voltage for equipment up to and including 72,5 kV and at least one winding operating at greater than 1,1 kV. This document does not apply to:
- gas-filled dry-type transformers where the gas is not air;
- single-phase transformers rated at less than 5 kVA;
- polyphase transformers rated at less than 15 kVA;
- instrument transformers;
- starting transformers;
- testing transformers;
- traction transformers mounted on rolling stock;
- flameproof and mining transformers;
- welding transformers;
- voltage regulating transformers;
- small power transformers in which safety is a special consideration.
Where IEC standards do not exist for the transformers mentioned above or for other special transformers, this document may be applicable as a whole or in parts.？ This second edition cancels and replaces the first edition published in 2004 and constitutes a technical revision. The main changes with regard to the previous edition are as follows:
- Extension of the scope up to 72,5kV
- Enclosure management in regards of the performance
- Management of the dielectric and thermal features with altitude
- New climatic classes for a better adaptation of customers’ need
- Establishment of the relation between location and environmental classes
- For fire behaviour classes, limitation at 1000kVA and process of test more robust
- Introduction of Seismic class
- Recommendations for amorphous transformers
