标准摘要
[中文适用范围]： 本部分文件规定了由铁氧体制成的优选波芯尺寸对于机械互换性的重要尺寸，以及与其配合使用的线圈骨架的极限尺寸，以及用于计算的有效参数值。它还给出了适用于波芯的表面不规则性允许极限的指南，依据相关通用规范。本文件中核心尺寸和形状的选择基于包括那些属于工业标准（无论是包含在国家标准中还是在行业内广泛使用）的尺寸的哲学。有关选择包含在内的核心尺寸的哲学的更多详细信息，请参阅IEC 62317-1。设计该系列核心的总体考虑因素见附录A。 [外文原描述]： IEC 63093-2:2020 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of pot-cores made of ferrite, and the dimensional limits for coil formers to be used with them, as well as the effective parameter values to be used in calculations involving them. It also gives guidelines on the allowable limits of surface irregularities applicable to pot-cores in accordance with the relevant generic specification. The selection of core sizes and shapes for this document is based on the philosophy of including those sizes which are industrial standards, either by inclusion in a national standard, or by broad-based use in industry. See IEC 62317-1 for more detail concerning the philosophy of selecting core sizes to be included. The general considerations upon which the design of this range of cores is based are given in Annex A. This first edition cancels and replaces the first edition of IEC 62317-2 published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition of IEC 62317-2: a) addition of the limits of surface irregularities; b) Table 4 and Table 5 are updated in accordance with IEC 60205:2016.
