标准范围

IEC 60376:2018定义了用于电气设备的技术级六氟化硫(SF6)和补充气体（如氮气(N2)和四氟化碳(CF4)）的质量。本文件还描述了检测技术，涵盖实验室和现场便携式仪器，适用于在将SF6、N2和CF4气体引入电气设备之前对这些气体进行分析。本文件提供了一些关于附件A中六氟化硫和附件B中六氟化硫的环境影响的信息。IEC 60480涵盖了有关SF6副产品的信息和评估SF6副产品对人类健康的潜在影响的程序，其处理和处置根据有关对环境影响的国际和当地法规进行。IEC 62271-4涵盖了SF6及其混合物的处理。IEC 60068-2-17中描述了确定SF6泄漏的程序。出于本文件的目的，SF6混合物中使用的补充气体将限于N2或CF4。这第三版取消并取代了2005年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)SF6在电气设备中的使用要求已得到确认；b)包括用于SF6与N2和CF4的混合物中的补充气体的规范；c)引言和范围已经合并；d)包括IEC 60376、IEC 60480和IEC 62271-4附件的新重新划分。

IEC 60376:2018 defines the quality for technical grade sulphur hexafluoride (SF₆) and complementary gases such as nitrogen (N₂) and carbon tetra-fluoride (CF₄), for use in electrical equipment. Detection techniques, covering both laboratory and in-situ portable instrumentation, applicable to the analysis of SF₆, N₂ and CF₄ gases prior to the introduction of these gases into the electrical equipment are also described in this document.
This document provides some information on sulphur hexafluoride in Annex A and on the environmental effects of SF₆ in Annex B.
Information about SF₆ by-products and the procedure for evaluating the potential effects of SF₆ by-products on human health are covered by IEC 60480, their handling and disposal being carried out according to international and local regulations with regard to the impact on the environment. Handling of SF₆ and its mixtures is covered by IEC 62271-4.
Procedures to determine SF₆ leakages are described in IEC 60068-2-17.
For the purposes of this document, the complementary gases used in SF₆ mixtures will be limited to N₂ or CF₄.
This third edition cancels and replaces the second edition published in 2005. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the requirements for the use of SF₆ in electrical equipment have been confirmed;
b) a specification for complementary gases to be used in SF₆ mixtures with N₂ and CF₄ has been included;
c) the introduction and scope have been merged;
d) a new repartition of the annexes of IEC 60376, IEC 60480 and IEC 62271-4 has been included.
