标准摘要
[中文适用范围]: 本部分 IEC 61558 涉及一般用途自耦变压器和包含一般用途自耦变压器的电源设备的安全。包含电子电路的变压器也适用于本文件。 注1:安全包括电气、热和机械方面。 除非另有规定,从下文开始,术语变压器涵盖一般用途自耦变压器和包含一般用途自耦变压器的电源设备。 对于线性电源设备,本文件适用。对于开关模式电源设备,IEC 61558-2-16 适用。 本文件适用于固定或便携式、单相或多相、风冷(自然或强制)独立或关联干式变压器。绕组可以封装或非封装。 额定电源电压不超过1000 V交流电,额定电源频率和内部工作频率不超过500 Hz。 核心功率不超过: - 单相变压器2 kVA; - 多相变压器10 kVA。 额定输出不超过: - 单相变压器40 kVA; - 多相变压器200 kVA。 本文件适用于核心功率和额定输出无限制的变压器,但需由买方和制造商协商。 适用时,空载输出电压或额定输出电压不超过1000 V交流电或1415 V无纹波直流电。对于独立变压器,空载输出电压和额定输出电压不小于50 V交流电或120 V无纹波直流电。 本文件不适用于拟连接到变压器输入端子和输出端子的外部电路及其组件。 注2:本文件涵盖的变压器仅用于安装规则或最终产品标准不要求电路间绝缘的应用。 未来变压器技术发展可能需要提高频率上限。在此之前,本文件可作为指导文件使用。 [外文原描述]: IEC 61558-2-13:2022 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61558-2-13:2022 deals with the safety of auto-transformers for general applications and power supply units incorporating auto-transformers for general applications. Transformers incorporating electronic circuits are also covered by this document. This third edition cancels and replaces the second edition published in 2009. 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; - description of constructions moved to IEC 61558-1:2017; - new symbol for power supply unit with linearly regulated output voltage. It has the status of a group safety publication in accordance with IEC Guide 104 .
