标准摘要
[中文适用范围]: 本国际标准适用于旨在并入电气设备、电子设备及其部件的热连接器,通常用于室内,以在异常条件下保护它们免受过高温度的影响。 注1:该设备并非设计用于产生热量。 注2:对过高温度的保护效果逻辑上取决于热连接器的位置和安装方法,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连接器,前提是此类热连接器周围的气候和其他环境条件与本标准中的条件相当。 本文件可能适用于其最简单形式的热连接器(例如熔断条或线),前提是在功能期间排出的熔融材料不会对设备的安全使用产生不利影响,特别是对于手持或便携式设备,无论其位置如何。 本文件的附件H适用于热连接器封装组件,其中热连接器已获批准符合本标准,但封装在金属或非金属外壳中并提供端子/引线。 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的热连接器。 本文件的目标是: a) 为热连接器建立统一要求, b) 定义测试方法, c) 为热连接器在设备中的应用提供有用信息。 本文件不适用于在极端条件下使用的热连接器,如腐蚀性或爆炸性环境。 本文件不适用于用于交流电路中频率低于45Hz或高于62Hz的热连接器。 [外文原描述]: IEC 60691:2023+AMD1:2024 CSV 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.
