电气设备标识与电源相关的额定值 - 安全要求

[中文适用范围]： 本国际标准确立了关于标注与任何电力供应相关的电气设备的额定值及其他特性的最低要求及一般规则，以使电气设备的选择和安装正确且安全。本文件的目的是：无限制地提供关于标注与任何供电系统相关的特性（如电压、电流、频率和功率）的一般要求；向技术委员会提供用于标注产品电气额定值的统一方法。本文件主要用于技术委员会在指定与任何电力供应相关的设备、子组件和部件的最低额定值标注时的应用，但也适用于产品制造商对其产品进行标注。 [外文原描述]： IEC 61293:2019 establishes minimum requirements and general rules on marking electric equipment with ratings and other characteristics to enable the proper and safe selection and installation of electric equipment related to any supply of electricity. The object of this document is to: • provide general requirements for the marking of the characteristics related to any supply system, such as voltage, current, frequency and power, without any restrictions; • provide technical committees with uniform methods for the marking of electrical ratings of products. This document is primarily intended for application by technical committees when specifying minimum markings of ratings related to any electrical supply of equipment, sub-assemblies and components, but it is also for application by product manufacturers for marking their products. This horizontal standard is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 108. One of the responsibilities of a technical committee is, wherever applicable, to make use of horizontal standards in the preparation of its publications. The contents of this horizontal standard will not apply unless specifically referred to or included in the relevant publications. IEC 61293:2019 cancels and replaces the first edition published in 1994. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) its status as a basic safety publication has been removed; b) the scope is extended to include the applicability of this document to product manufacturers; c) the addition of a provision that the visibility of the marking during normal operation should be considered; d) more detailed requirements where equipment has a set or range of rated values for a given characteristic; e) requirements regarding the provision of the markings also in the technical documentation have been added; f) some notes have been converted to normative text; g) normative references and references to other standards have been updated. It has the status of a horizontal standard in accordance with IEC Guide 108 .
