标准摘要
[中文适用范围]： IEC 62271 的本部分适用于 IEC 62271-200 或 IEC 62271-201 涵盖的交流开关设备和控制设备中集成的电压存在指示系统 (VPIS)。电压存在指示系统是用于向操作员提供有关安装该系统的开关设备主电路电压状况信息的设备。仅 VPIS 的指示不足以证明系统已死亡：如果操作程序强制要求这样做，则应使用符合 IEC 61243-1、IEC 61243-2 和 IEC 61243-5 的相关电压检测器。该标准也适用于专门设计用于 VPIS 的相位比较器。 [外文原描述]： IEC 62271-206:2011 is applicable to voltage presence indicating systems (VPIS) incorporated in a.c. switchgear and controlgear covered by IEC 62271-200 or IEC 62271-201. Voltage presence indicating systems are devices used to provide information to operators about the voltage condition of the main circuit of the switchgear in which they are installed. This first edition of IEC 62271-206 cancels and replaces the first edition of IEC 61958. This edition constitutes a minor revision. The main changes with respect of the first edition of IEC 61958 are an actualization of references and the degree of protection which has been changed from IPXXB to IP2X.
英文名称High-voltage switchgear and controlgear - Part 206: Voltage presence indicating systems for rated voltages above 1 kV and up to and including 52 kV
