电子设备用固定电容器第17部分:分规范金属化聚丙烯膜介质交流和脉冲固定电容器

[中文适用范围]： 本部分IEC 60384适用于用于电子设备的具有金属化电极和聚丙烯介电质的固定电容器。注：具有混合箔膜和金属化电极的电容器也在此标准范围内。这些电容器可能根据使用条件具有“自愈”特性。本规范涵盖的电容器主要用于交流电压和/或脉冲应用。适用的最大无功功率为10000 var，最大峰值电压为3000 V。对于无功功率超过500 var且可施加50 Hz下最大2500 V峰值电压的电容器，除其属于主要在50 Hz下无功功率低于500 var的范围内最高部分外，本文件不涵盖。本文件不旨在涵盖高于20μF的电容器值。涵盖两种性能等级的电容器：等级1用于长寿命应用，等级2用于一般应用。不包括用于电磁干扰抑制的电容器，后者由IEC 60384-14涵盖。也不包括用于电气 shock 危害保护的电容器（由IEC技术委员会61的IEC 60065涵盖），以及荧光灯和电机用的电容器（由IEC技术委员会33的IEC 60252-1和IEC 60252-2涵盖），以及用于管荧光灯和其他放电灯电路的电容器（由IEC技术委员会34的IEC 61048和IEC 61049涵盖）。 [外文原描述]： IEC 60384-17:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60384-17:2019 applies to fixed capacitors with metallized electrodes and polypropylene dielectric for use in electronic equipment. Capacitors that have mixed film and metallized electrodes are also within the scope of this standard. These capacitors may have "self-healing" properties depending on conditions of use. Capacitors covered by this specification are mainly intended for use with alternating voltage and/or for pulse applications. The maximum reactive power applicable is 10 000 var and the maximum peak voltage is 3 000 V. This edition includes the following significant technical changes with respect to the previous edition: a) all parts of the document have been revised based on the ISO/IEC Directives, Part 2:2016 (seventh edition) and harmonization between other similar kinds of documents; b) tables and Clause 4 have been revised so as to prevent duplications and contradictions; c) new damp heat steady-state robustness classes with test conditions have been added in text, in Clause 4 and in Annex A. The contents of the corrigendum of December 2020 have been included in this copy.
