标准摘要
[中文适用范围]： 替代：IEC 61558 第 2 部分适用于固定式或便携式@单相或多相@风冷安全隔离变压器@相关或其他@额定电源电压不超过 1000 V 交流且额定频率不超过 500 Hz@额定输出不超过：单相变压器≤C 10 kVA； ?C 16 kVA 用于多相变压器。本标准也适用于不受额定输出限制的安全隔离变压器；然而，此类变压器被视为特殊变压器，并须经买方和供应商之间达成协议。空载输出电压和额定输出电压不超过：导体之间或任何导体与地之间 50 V acrms 和/或 120 V 无纹波直流电。本标准适用于干式变压器。绕组可以是封装的或非封装的。 [外文原描述]： IEC 61558-2-6:2009 deals with the safety of safety isolating transformers for general applications and power supply units incorporating safety isolating transformers for general applications. Transformers incorporating electronic circuits are also covered by this standard. This second edition cancels and replaces the first edition published in 1997. It constitutes a technical revision. The main changes consist of updating this part in accordance with Part 1 (2005), and increasing the supply voltages up to 1 100 V to be in line with the standards of TC 14. This part has the status of a group safety publication in accordance with IEC Guide 104. This part is intended to be used in conjunction with the latest edition of IEC 61558-1 and its amendments. It is based on the second edition (2005) of that standard. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months from the date of publication.
