IEC 62271-4:20 22适用于安装、调试、维修、大修、正常和异常操作期间绝缘和/或开关用气体的处理程序以及结束时的处置？的？电力设备的寿命。 这些程序被视为确保电力设备的可靠性、使用这些气体的人员的安全以及将对环境的影响降至最低的最低要求。制造商的操作说明手册中可以给出或规定附加要求。 第二版取消并取代了2013年发布的第一版IEC 62271-4。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: 标题已被修改； 增加了用于绝缘和/或开关的SF6替代品的处理程序； 主条款与气体类型无关； 对于每种气体，单独的附件描述了气体的具体信息、处理程序、安全措施等。； 关于SF6（原附件E）和SF6及其混合物的环境影响（原附件F）的信息已移至IEC 60376； 关于SF6及其混合物的副产品（原附件G）、评估SF6及其混合物的副产品对健康的潜在影响的程序（原附件H）和SF6的低温回收（原附件I）的信息已移至IEC 60480。

IEC 62271-4:2022 applies to the procedures for handling of gases for insulation and/or switching during installation, commissioning, repair, overhaul, normal and abnormal operations and disposal at the end？of？life of electric power equipment.
These procedures are regarded as minimum requirements to ensure the reliability of electric power equipment, the safety of personnel working with these gases and to minimize the impact on the environment. Additional requirements could be given or specified in the operating instruction manual of the manufacturer.
This second edition cancels and replaces the first edition of IEC 62271-4 published in 2013. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:

1. title has been modified;
2. handling procedures of alternatives to SF₆, which are used for insulation and/or switching, are added;
3. the main clauses are independent from the type of gas;
4. for each gas a separate annex describes gas specific information, handling procedures, safety measure, etc.;
5. information about SF₆ (former Annex E) and about environmental effects of SF₆ and its mixtures (former Annex F) has been moved to IEC 60376;
6. information about by-products of SF₆ and its mixtures (former Annex G), the procedure for evaluating the potential effects on health of by-products of SF₆ and its mixtures (former Annex H) and the cryogenic reclaim of SF₆ (former Annex I) have been moved to IEC 60480.
