标准范围

IEC 63093-2:20 20规定了对于由铁氧体制成的罐芯的优选范围的机械互换性很重要的尺寸，以及与它们一起使用的线圈成型机的尺寸限制，以及在涉及它们的计算中使用的有效参数值。它还根据相关通用规范给出了适用于锅芯的表面不规则性允许限值的指南。本文件核心尺寸和形状的选择基于包括工业标准尺寸的理念，无论是通过纳入国家标准还是通过在工业中广泛使用。有关选择要包含的芯尺寸的原理的更多详细信息，请参见IEC 62317-1。附录A给出了该系列磁芯设计所依据的一般考虑因素。本第一版取消并取代了2010年发布的IEC 62317-2第一版。本版构成技术修订版。与上一版IEC 62317-2相比，此版本包括以下重大技术变更:a)增加表面不规则性的限制；b)根据IEC 60205:2016更新表4和表5。

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.
