标准摘要
[中文适用范围]： 本部分IEC 63093规定了EFD磁芯机械互换性的重要尺寸、与EFD磁芯配套使用的线圈骨架的基本尺寸，以及计算中使用的有效参数值。还根据相关通用规范给出了EFD磁芯表面不规则性的允许限值指南。 本文件选择磁芯尺寸的哲学是基于那些已成为工业标准的尺寸，这些尺寸要么被纳入国家标准，要么在工业中广泛使用。 本规范有助于铁氧体磁芯制造商和用户之间就表面不规则性进行谈判。 该系列磁芯设计的一般考虑因素见附录A。 [外文原描述]： IEC 63093-14:2019 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of EFD-cores, the essential dimensions of coil formers to be used with them, and the effective parameter values to be used in calculations involving them. It also gives guidance on the allowable limits of surface irregularities applicable to EFD-cores in accordance with the relevant generic specification. The selection of core sizes for this document is based on the philosophy of including those sizes which are industrial standards, either by inclusion in national standards, or by broad-based use in industry. This document is a specification useful in the negotiation between ferrite core manufacturers and users about surface irregularities. This first edition cancels and replaces the first edition of IEC 62317-14 published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 62317-14:2008: guidelines on the limits of surface irregularities of EFD-cores were added.
