标准摘要
[中文适用范围]： 本部分IEC 61558涉及高绝缘等级隔离变压器和输出电压超过1000V的隔离变压器的安全性。包含电子电路的变压器也适用于本文件。 本文件适用于静止或便携式、单相或多相、风冷（自然或强制）独立或关联干式变压器。绕组可以是封装或非封装的。 额定电源电压不超过1000V交流电，额定电源频率和内部工作频率不超过500Hz。 额定输出不超过：单相变压器25kVA；多相变压器40kVA。 本文件不适用于：IEC 60076-11涵盖的变压器；IEC 61050涵盖的霓虹变压器；以及根据IEC 61347-2-10用于产品或产品中的电源和转换器。 [外文原描述]： IEC 61558-2-10:2024 deals with the safety of separating transformers with high insulation level and separating transformers with output voltages exceeding 1 000 V. Transformers incorporating electronic circuits are also covered by this document. This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) adjustment of structure and references in accordance with IEC 61558-1:2017; b) overvoltage categories I, II, III and IV for clearances and dielectric strength tests are included; c) clearances for homogenous field conditions deleted. It has the status of a group safety publication in accordance with IEC Guide 104.
