+AMD1:2025 CSV 电子设备用固定电容器 第14部分：分规范 电磁干扰抑制和电源连接用固定电容器

[中文适用范围]： IEC 60384-14:2023+AMD1:2025 CSV适用于额定电压不超过1000 V交流（有效值）、额定频率不超过100 Hz的交流电源或其他供电系统连接的电容器和电阻-电容组合。本文件还包括针对额定电压不超过1500 V直流电源连接的附加具体条件和要求。IEC 60384本部分的主要目的是规定推荐的额定值和特性，并从IEC 60384-1中选取适当的合格评定程序、测试和测量方法，同时提供此类电容器的一般性能要求。参考本分规范的详细规范中规定的所有测试严酷度和要求，其性能等级应等于或高于本规范；不允许使用较低的性能等级。本文件还为需要此类机构批准的国家的国家测试机构提供了一套安全测试计划。本文件中电容器与交流电源电压组合的过电压类别应参照IEC 60664-1。与前一版相比，本次修订包含以下重大技术变更：- 在湿热稳态测试中，所有类型的电容器在有和无额定电压的情况下均进行了测试，且测试样品数量增加；- 在安全测试中，增加了“损耗角正切”作为第0组测试的一部分；- 基于安全性和性能测试的合格批准已从正文移至规范性附录；- 使用额定电压范围代替了具体的额定电压值；- 增加了关于电容器样式及爬电/电气间隙测量的规范性附录；- 在所有相关测试后的处理说明和要求中，突出了组件封装中机械故障（如裂纹）作为安全特性的重要性。本修订中已包含2024年10月发布的勘误表1的内容。 [外文原描述]： IEC 60384-14:2023+AMD1:2025 CSV applies to capacitors and resistor-capacitor combinations intended to be connected to AC mains or other supply with a nominal voltage not exceeding 1 000 V AC (RMS), and with a nominal frequency not exceeding 100 Hz. This document includes also additional specific conditions and requirements for the connection to DC supplies with a rated voltage not exceeding 1 500 V DC. The principal object of this part of IEC 60384 is to prescribe preferred ratings and characteristics and to select, from IEC 60384-1, the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements prescribed in detail specifications referring to this sectional specification are of equal or higher performance level; lower performance levels are not permitted. This document also provides a schedule of safety tests to be used by national testing stations in countries where approval by such stations is required. The overvoltage categories in combination with the AC mains voltages for the capacitors classified in this document are to be taken from IEC 60664-1. This edition includes the following significant technical changes with respect to the previous edition: - in damp heat steady state test, all capacitor types are tested both with and without rated voltage; the number of test pieces has been increased; - tangent of loss angle is added In Group 0 tests, in safety tests only; - qualification approval based on safety and performance tests has been removed from the main text to a normative annex; - the range of rated voltages is given instead of exact rated voltage values; - normative annex for description of capacitor styles and of creepage/clearance distance measurement has been added; - the importance of mechanical failures (cracks) in component encapsulation as a safety feature is highlighted in handling instructions and requirements after all relevant tests. The content of the corrigendum 1 (2024-10) has been included in this copy.
