标准摘要
[中文适用范围]： 本标准适用于高压开关设备和控制设备中六氟化硫（SF6）在安装、调试、正常运行和异常操作以及寿命终结处置过程中的处理程序。这些程序被视为确保工作人员使用SF6的安全（见附录B）并最大限度地减少SF6向环境排放的最低要求。本标准通常也适用于含SF6的气体混合物。其处理的特殊性见附录J。注1： throughout this standard, 术语“高压（High-Voltage）”（参考IEC 60050-601:1985, 601-01-27）指额定电压高于1000 V。然而，术语“中压（Medium Voltage）”（参考IEC 60050-601:1985, 601-01-28）通常用于指代电压高于1 kV并通常应用于高达52 kV的配电系统。注2： throughout this standard，术语“电力设备（electric power equipment）”指“高压和中压开关设备和控制设备”。注3： throughout this standard，术语“压力（pressure）”指“绝对压力”。 [外文原描述]： IEC 62271-4:2013 applies to the procedures for handling of SF6 during installation, commissioning, normal and abnormal operations, disposal at the end of life of high voltage switchgear and controlgear. This first edition cancels and replaces the first edition of IEC/TR 62271-303 published in 2008. This first edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the description of the potential effects on health of SF6 by products (former Annex D of IEC/TR 62271-303:2008) has been replaced by the calculation methods for evaluating of the potential effects on health of SF6 by products (see Annex H); b) information about cryogenic reclaim of SF6. Have been added (see Annex I); c) handling procedures for the most popular SF6 mixtures have been added (see Annex J).
