标准摘要
[中文适用范围]： 本国际标准适用于电力电子应用中的电容器。这些电容器所在系统的运行频率通常高达15kHz，而脉冲频率可能高达运行频率的5至10倍。本文件区分了交流和直流电容器，当安装在机箱中时被视为组件。本文件涵盖了多种应用的广泛电容器技术，例如过压保护、直流和交流滤波、开关电路、直流能量存储、辅助逆变器等。以下内容不包括在本文件中： - 用于感应加热设备的电容器，工作频率范围高达50kHz（参见IEC 60110-1和IEC 60110-2）； - 用于电机应用等的电容器（参见IEC 60252-1和IEC 60252-2）； - 用于阻止电源网络中一个或多个谐波的电容器； - 用于荧光灯和放电灯的小型交流电容器（参见IEC 61048和IEC 61049）； - 用于抑制无线电干扰的电容器（参见IEC 60384-14）； - 额定电压高于1000V的交流电力系统并联电容器（参见IEC 60871标准）； - 额定电压高达1000V的自愈型交流系统并联电力电容器（参见IEC 60831-1和IEC 60831-2）； - 额定电压高达1000V的非自愈型交流系统并联电力电容器（参见IEC 60931标准）； - 不用于电力电路的电子电容器； - 用于电力系统的串联电容器（参见IEC 60143）； - 耦合电容器和电容分压器（参见IEC 60358）； - 用于微波炉的电容器（参见IEC 61270-1）； - 用于铁路应用的电容器（参见IEC 61881）。 应用示例见9.1节。 [外文原描述]： IEC 61071:2017 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 61071:2017 applies to capacitors for power electronics applications. The operating frequency of the systems in which these capacitors are used is usually up to 15 kHz, while the pulse frequencies may be up to 5 to 10 times the operating frequency. The document distinguishes between AC and DC capacitors which are considered as components when mounted in enclosures. This document covers an extremely wide range of capacitor technologies for numerous applications, e.g. overvoltage protection, DC and filtering, switching circuits, energy storage, auxiliary inverters, etc. This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - Introduction of new terms and definitions; - clarifications for surge discharge test; - indications for measuring procedure during thermal stability test; - clarifications for self-healing test; - clarifications for endurance test; - clarifications for destruction test; - update of normative references; - general editorial review.
