仪表用变压器 第11部分:低功率无源电压互感器的附加要求

[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压互感器（无源 LPVT）的附加要求。小功率无源电压互感器的产品标准由IEC 61869-1@和IEC 61869-6以及本具有具体要求的文件组成。本标准适用于新生产的模拟输出、额定频率为15Hz～100Hz、与电气测量仪器或电气保护装置配套使用的小功率无源电压互感器。本文件涵盖用于测量或保护的低功率无源电压互感器以及用于测量和保护的低功率无源电压互感器。低功率无源电压互感器仅具有模拟输出（对于数字输出或使用任何类型有源电子元件的技术，请参阅未来的 IEC 61869-72）。这种低功率无源电压互感器可以包括次级信号电缆（传输电缆）。小功率无源变压器的次级电压与初级电压成正比。导数输出信号不在本文档的讨论范围内。 [外文原描述]： IEC 61869-11:2017 is a product standard and covers only additional requirements for low-power passive voltage transformers (passive LPVT). The product standard for low-power passive voltage transformers is composed of IEC 61869-1, along with IEC 61869-6 and this document with specific requirements. This document is applicable to newly manufactured low-power passive voltage transformers with analogue output having rated frequencies from 15 Hz to 100 Hz for use with electrical measuring instruments or electrical protective devices. This document covers low-power passive voltage transformers used for measurement or protection and low-power passive voltage transformers used for both measurement and protection. Low-power passive voltage transformers have analogue output only (for digital output or for technology using any kind of active electronic components refer to future IEC 61869-7). Such low-power passive voltage transformers can include the secondary signal cable (transmitting cable). The secondary voltage of the low-power passive voltage transformer is proportional to the primary voltage. Derivative output signals are not within the scope of this document. This first edition of IEC 61869-11, together with IEC 61869-1 and IEC 61869-6, cancels and replaces the relevant clauses or subclauses of the first edition of IEC 60044-7, published in 1999 and the first edition of IEC 60044-8, published in 2002. This edition constitutes a technical revision. The contents of the Interpretation Sheet 1 of September 2021 have been included in this copy.
