标准摘要
[中文适用范围]： 本文件适用于包含电子电路的变压器，但不包括外部电路。适用于单相或多相风冷开关模式电源（SMPS）中使用的相关变压器，内部频率超过500 Hz： - 隔离变压器 - 安全隔离变压器 额定电源电压不超过1000 V AC，额定频率超过500 Hz但不超过100 MHz，额定输出不超过： - 单相变压器25 kVA - 多相变压器40 kVA 变压器的空载输出电压或额定输出电压不超过： - 隔离变压器使用时1000 V AC或1415 V DC - 安全隔离变压器使用时500 V AC或708 V DC - 安全隔离变压器使用时50 V AC或120 V DC 本文件适用于干式变压器，绕组可以是封装或非封装的。 [外文原描述]： IEC 61558-2-16:2021 deals with the safety of switch mode power supply units and transformers for switch mode power supply units. This second edition cancels and replaces the first edition published in 2009 and amendment 1:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - adjustment of structure and references in accordance with IEC 61558-1:2017; - definitions of different voltage characteristics; - partial discharge and description of constructions moved to IEC 61558-1:2017; - alternative method for dimensioning of clearances; - removal of requirements for homogeneous field conditions. It has the status of a group safety publication in accordance with IEC Guide 104. This International Standard is to be used in conjunction with IEC 61558-1:2017. The contents of the corrigendum 1 (2023-09) have been included in this copy.
