仪表变压器. 第10部分:低功率无源电流互感器的附加要求

[中文适用范围]： IEC 61869 的这一部分是产品标准，仅涵盖低功率无源电流互感器的附加要求。小功率无源电流互感器的产品标准包括 IEC 61869-1、IEC 61869-6 以及具有具体要求的本文件。本标准适用于额定频率为15Hz～100Hz的电气测量仪表或电气保护装置中使用的新制造的具有模拟输出的小功率无源电流互感器。本文件涵盖用于测量或保护的低功率无源电流互感器以及用于测量和保护的多用途低功率无源电流互感器。第 5.6.1001 款涵盖了与电气测量仪器一起使用的低功率无源电流互感器所需的精度要求。第 5.6.1002 款涵盖了与电气保护继电器一起使用的低功率无源电流互感器所需的精度要求，特别是对于主要要求是保持精度高达额定电流数倍的保护形式。如果需要，5.6.1002 中还给出了故障期间小功率无源电流互感器的暂态精度。低功率无源电流互感器仅具有模拟电压输出（对于数字输出或使用任何类型有源电子元件的技术，请参阅 IEC 61869-82）。这种低功率无源电流互感器可以包括次级信号电缆（传输电缆）。附件 10B 给出了使用空心线圈（罗氏线圈）的派生小功率无源电流互感器的工作原理，使用带集成分流器的铁芯线圈的比例式小功率无源电流互感器的工作原理在附件 10C。 [外文原描述]： IEC 61869-10:2017 is a product standard and covers only additional requirements for low-power passive current transformers. The product standard for low-power passive current transformers comprises IEC 61869-1, together with IEC 61869-6 and this document with specific requirements. This document is applicable to newly manufactured low-power passive current transformers with analogue output for use with electrical measuring instruments or electrical protective devices having a rated frequency from 15 Hz to 100 Hz. This document covers low-power passive current transformers used for measurement or protection and multi-purpose low-power passive current transformers used for both measurement and protection. This first edition of IEC 61869-10, together with IEC 61869-1, IEC 61869-6, IEC 61869-8 and IEC 61869-9, cancels and replaces the first edition of IEC 60044-8, published in 2002. This edition constitutes a technical revision. The technical changes concern IEC TC 38's decision to restructure the whole set of stand-alone standards in the IEC 60044 series and transform it into a new set of standards composed of general requirements documents and specific requirements documents.
