热链接.要求和应用指南

[中文适用范围]： 本国际标准适用于旨在用于电气设备、电子设备及其部件的热熔断器，通常用于室内，以在异常条件下保护它们免受过高的温度。 注1：该设备并非设计用于发热。 注2：对过高温度的保护效果逻辑上取决于热熔断器的安装位置和方式，以及其承载的电流。 本文件可能适用于在非室内条件下使用的热熔断器，前提是这些热熔断器周围的气候和其他环境条件与本标准中的条件相当。 本文件可能适用于最简单形式的热熔断器（例如熔断条或线），前提是在功能过程中排出的熔融材料不会对设备的安全使用造成不利影响，尤其是在手持或便携式设备中，无论其位置如何。 本文件的附录H适用于热熔断器封装组件，其中热熔断器已根据本标准批准，但封装在金属或非金属外壳中，并配有端子/导线。 本文件适用于额定电压不超过690V交流或直流且额定电流不超过63A的热熔断器。 本文件的目标是： a) 为热熔断器建立统一的要求， b) 定义测试方法，以及 c) 为热熔断器在设备中的应用提供有用的信息。 本文件不适用于在极端条件下使用的热熔断器，如腐蚀性或爆炸性环境。 本文件不适用于在交流电路中使用的热熔断器，其频率低于45Hz或高于62Hz。 [外文原描述]： IEC 60691:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60691:2023 is applicable to thermal-links intended for incorporation in electrical appliances, electronic equipment and component parts thereof, normally intended for use indoors, in order to protect them against excessive temperatures under abnormal conditions. NOTE 1 The equipment is not designed to generate heat. NOTE 2 The effectiveness of the protection against excessive temperatures logically depends upon the position and method of mounting of the thermal-link, as well as upon the current which it is carrying. This document may be applicable to thermal-links for use under conditions other than indoors, provided that the climatic and other circumstances in the immediate surroundings of such thermal-links are comparable with those in this standard. This document may be applicable to thermal-links in their simplest forms (e.g. melting strips or wires), provided that molten materials expelled during function cannot adversely interfere with the safe use of the equipment, especially in the case of hand-held or portable equipment, irrespective of its position.
