标准摘要
[中文适用范围]: 替代:本国际标准涉及安全的各个方面,例如电气@热和机械。IEC 61558的第2-13部分适用于固定式或便携式@单相或多相@风冷(自然或强制)@独立或联动汽车- 变压器 @ 额定电源电压不超过 1 000 V ac@ 额定频率不超过 500 Hz。 核心功率不超过: 单相自耦变压器 ?C 1 kVA;多相自耦变压器 ?C 5 kVA额定输出不超过:单相自耦变压器≤C 20 kVA;多相自耦变压器≤C 100 kVA。本标准也适用于芯功率不超过40 kVA@的自耦变压器。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。此类专用自耦变压器对额定输出没有限制。空载输出电压和额定输出电压不超过1 000 V交流或1 415 V无纹波直流。对于独立自耦变压器@空载输出电压额定输出电压不低于 50 V 交流或 120 V 无纹波直流 本标准适用于安装规则或设备规范要求电路间不绝缘的变压器。 注 1 ?C 通常@变压器是预期的与设备相关联,为设备的功能要求提供与电源电压不同的电压。安全绝缘可由设备的其他特征(例如本体)提供。本标准适用于干式变压器。绕组可以是封装的或非封装的。 注 2 ?C 对于充满液体电介质或粉末材料@(例如沙子@)的变压器,要求正在考虑中。注 3 ?C 请注意以下事实:?C 对于预期的变压器用于车辆或船上或飞机@可能需要附加要求;?C 用于热带国家的变压器@可能需要特殊要求;?C 在特殊环境条件普遍存在的地方@可能需要特殊要求本标准也适用于包含电子电路的变压器。本标准不适用于连接到变压器输入输出端子或插座的外部电路及其组件。本标准不适用于IEC 60989中描述的可变自耦变压器。 [外文原描述]: IEC 61558-2-13:2009 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 standard. This second edition cancels and replaces the first edition published in 1999. 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.
