IEC 60034-18-1:20 22 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单的方法来比较IEC 60034-18-1:20 22版3.0和之前的IEC 60034-18-1:20 10版2.0之间的所有更改。此外，还提供了IEC TC 2专家的意见，以解释最相关变更的原因，或澄清内容的任何部分。 IEC 60034-18-1:20 22涉及IEC 60034-1范围内用于或拟用于旋转电机的电气绝缘系统功能评估的一般指南，以使其合格。IEC 60034-18-1定义了绝缘系统鉴定的一般要求，根据许多经验，对于热老化，阿伦尼乌斯方程不一定适合。这第三版取消并取代了2010年出版的第二版。与上一版相比，此版本包括以下重大技术变更: a.与以前一样，为不同类型绕组的功能评估提供了一般指南，但纳入了为受变流器电源电应力的绕组的电气鉴定和评估而引入的那些变化； b.现在侧重于一般指南，程序和资格原则的所有技术细节都转移到后续部分； c.详细介绍了功能评估和鉴定的其他一般方面，特别是参考绝缘系统和候选绝缘系统之间的比较程序、不同预期使用寿命的鉴定概念的引入以及微小部件或制造变更的评估。

IEC 60034-18-1:2022 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 60034-18-1:2022 edition 3.0 and the previous IEC 60034-18-1:2010 edition 2.0. Furthermore, comments from IEC TC 2 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content.

IEC 60034-18-1:2022 deals with the general guidelines for functional evaluation of electrical insulation systems, used or proposed to be used in rotating electrical machines within the scope of IEC 60034-1, in order to qualify them. IEC 60034-18-1 defines general requirements on the qualification of insulation systems, where – for thermal ageing – the Arrhenius equations do not necessarily fit, according to many experiences.

This third edition cancels and replaces the second edition published in 2010. This edition includes the following significant technical changes with respect to the previous edition:
a. provides general guidelines for functional evaluation of different types of windings as before but incorporates those changes, which have been introduced for the electrical qualification and evaluation of windings which are electrically stressed by converter-supply;
