标准摘要
[中文适用范围]： 本部分 IEC 60317 规定了 120 级聚缩醛或聚缩甲醛树脂基单层涂漆圆铜绕线要求，只要其保持原始树脂的化学特性并满足所有规定的绕线要求，可进行改性。 注1：改性树脂是经过化学变化或含有一种或多种添加剂的树脂，以增强某些性能或应用特性。 注2：聚缩醛是聚缩醛树脂家族的通称，由聚缩醛醇与醛缩合生成的热塑性乙烯基树脂。例如聚缩醛、聚缩甲醛和聚缩丁醛。 本文件涵盖的公称导体直径范围如下： - 等级1：0.040 mm 至并包括 2.500 mm； - 等级2：0.040 mm 至并包括 5.000 mm； - 等级3：0.080 mm 至并包括 5.000 mm。 公称导体直径在 IEC 60317-0-1:2013 的第4条中规定。 [外文原描述]： IEC 60317-12:2020+AMD1:2024 CSV specifies the requirements of enamelled round copper winding wires of class 120 with a sole coating based on polyvinyl acetal or polyvinyl formal resin, which can be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements. NOTE 1 A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics. NOTE 2 Polyvinyl acetal is a general name for a family of thermoplastic vinyl resins produced by the condensation of polyvinyl alcohol with an aldehyde. Examples are polyvinyl acetal, polyvinyl formal and polyvinyl butyral. The range of nominal conductor diameters covered by this document is: - Grade 1: 0,040 mm up to and including 2,500 mm; - Grade 2: 0,040 mm up to and including 5,000 mm; - Grade 3: 0,080 mm up to and including 5,000 mm. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013. This fourth edition of IEC 60317-12 cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - modification of the Scope; - addition of reference to transformer oil resistance test method in Clause 20.
