标准摘要
[中文适用范围]： 本部分IEC 62271适用于设计用于插入电压检测和指示系统(VDIS)测试点的相位比较器，根据IEC 62271-213，以指示相位比较的结果。主要用途是在连接之前，为高压网络中两个带电部分在相同标称电压和频率下的相位关系提供明确证据。本文件或部分内容也可在制造商和用户协议下，应用于连接到VDIS的其他设备的相位比较功能。本文件不涵盖直接用于带电电气安装裸部件上的相位比较器，这些相位比较器由IEC 61481-1和IEC 61481-2涵盖。 [外文原描述]： IEC 62271-215:2021 is applicable to phase comparators designed to be plugged into the testing points of a voltage detecting and indicating system (VDIS) according to IEC 62271-213, to give an indication of the result of a phase comparison. The main usage is to provide a clear evidence of the phase relationship between two energized parts of a high-voltage network, at the same nominal voltage and frequency before coupling them. This first edition cancels and replaces the first edition of IEC 61243-5 published in 1997 and the first edition of IEC 62271-206 published in 2011. This edition constitutes a merging of the content of IEC 61243-5 and IEC 62271-206. This edition includes the following significant technical changes with respect to the previous editions of IEC 61243-5 and IEC 62271-206: the document does not include the specific phase comparators (SPCs) as defined in IEC 61243-5, which was specific to manufacturers, and takes back the technical principles of the universal phase comparator (UPC) for VDIS of all manufacturers; the phase comparator for sequential connected operation is introduced to facilitate the operation of phase comparation of large MV panels.
