IEC 60567:2023 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 60567:2023版5.0和之前的IEC 62631-3-2:20 11版4.0之间的所有更改。此外，还提供了IEC TC 10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 60567:2023涉及从电力变压器集气继电器中对游离气体进行采样的技术。描述了三种游离气体取样的方法。本文件不再涵盖从电力和仪表变压器、电抗器、套管、充油电缆和充油槽式电容器等充油设备中取样油的技术，而是在IEC 60475中描述:2022,4.2.在分析溶解在油中的气体之前，首先从油中提取它们。描述了三种基本方法，一种使用真空萃取（Toepler和部分脱气），另一种通过使载气鼓泡通过油样品来置换溶解的气体（汽提），最后一种通过在油样品和小体积载气之间分配气体（顶部空间）。提取后用气相色谱法对气体进行定量分析；描述了一种分析方法。来自气体收集继电器的游离气体在没有初步处理的情况下进行分析。

IEC 60567:2023 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 60567:2023 edition 5.0 and the previous IEC 62631-3-2:2011 edition 4.0. Furthermore, comments from IEC TC 10 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content.

IEC 60567:2023 deals with the techniques for sampling free gases from gas-collecting relays from power transformers. Three methods of sampling free gases are described. The techniques for sampling oil from oil-filled equipment such as power and instrument transformers, reactors, bushings, oil-filled cables and oil-filled tank-type capacitors are no longer covered by this document, but are instead described in IEC 60475:2022, 4.2. Before analysing the gases dissolved in oil, they are first extracted from the oil. Three basic methods are described, one using extraction by vacuum (Toepler and partial degassing), another by displacement of the dissolved gases by bubbling the carrier gas through the oil sample (stripping) and the last one by partition of gases between the oil sample and a small volume of the carrier gas (headspace). The gases are analysed quantitatively after extraction by gas chromatography; a method of analysis is described. Free gases from gas-collecting relays are analysed without preliminary treatment.
