电力测量设备（Ac） - 一般要求 测试和测试条件 - 第31部分:产品安全要求和测试

[中文适用范围]： IEC 62052-31 规定了用于电气能量测量和控制设备的产物安全要求。本国际标准适用于新制造的计量设备，设计用于在 50 Hz 或 60 Hz 网络（电压最高可达 600 V）上测量和控制电能，且所有功能元件（包括附加模块）均封装在或形成一个单一外壳内。本国际标准也适用于包含供电和负载控制开关的计量设备，但仅限于机电式操作的开关。当此类设备设计为安装在特定的匹配插座中时，要求适用于安装在指定匹配插座中的设备，测试也应在该装置上进行。然而，关于插座以及将电能表插入/拔出插座的要求不在本标准范围内。本国际标准也适用于辅助输入和输出电路。本标准区分了：机电式电能表、静态电能表和负荷控制设备；直接连接、电流互感器操作、电压和电流互感器操作的电能表；保护 Class I 和保护 Class II 设备；壁挂式或柜式安装、机架式安装和面板式安装设备；室内和室外使用的设备。本国际标准不适用于：中性线电压超过 600 V 的设备；便携式电能表（非永久连接的电能表）；实验室和移动式电能表测试设备；标准参考电能表。 [外文原描述]： IEC 62052-31:2015 specifies product safety requirements for equipment for electrical energy measurement and control. It applies to newly manufactured metering equipment designed to measure and control electrical energy on 50 Hz or 60 Hz networks with a voltage up to 600 V, where all functional elements, including add-on modules are enclosed in or form a single case. When such equipment is designed to be installed in a specified matching socket, then the requirements apply to, and the tests shall be performed on, equipment installed in its specified matching socket. However, requirements for sockets and inserting / removing the meters from the socket are outside the scope of this standard. This International Standard is also applicable to auxiliary input and output circuits. This bilingual version (2016-11) corresponds to the monolingual English version, published in 2015-09.
