微型熔断器 第 1 部分：微型熔断器的定义和微型熔断体的一般要求

[中文适用范围]： IEC 60127-1 适用于所有类型的微型熔断器（例如：管式微型熔断器、次微型熔断器、通用模块化熔断器和特殊应用微型熔断器），用于保护通常用于室内的电器、电子设备及其零部件。本文件不适用于用于保护低压电气安装装置的熔断器（这些由 IEC 60269 涵盖）。不适用于用于特殊条件（如腐蚀性或爆炸性气氛）下使用的电器中的熔断器。本文件旨在：a) 建立微型熔断器的统一要求，以最合适的方式保护电器或其部件；b) 定义熔断器的性能，为电器和电子设备的设计者提供指导，并确保使用相同尺寸和特性的熔断器进行替换；c) 定义测试方法；d) 定义熔断器的最大持续功耗，以确保与根据本文件制造的熔断器座具有良好兼容性。 [外文原描述]： IEC 60127-1:2023 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 60127-1:2023 covers the general requirements and tests applicable to all types of miniature fuse-links (e.g. cartridge fuse-links, sub-miniature fuse-links, universal modular fuse-links and miniature fuse-links for special applications) for the protection of electric appliances, electronic equipment and component parts thereof normally intended to be used indoors. This document does not apply to fuses intended for the protection of low-voltage electrical installations. These are covered by IEC 60269, Low Voltage Fuses. Specific details covering each major subdivision are given in subsequent parts. This document does not apply to fuses for appliances intended to be used under special conditions, such as in a corrosive or explosive atmos­phere. The object of this document is - to establish uniform requirements for miniature fuses so as to protect appliances or parts of appliances in the most suitable way, - to define the performance of the fuses, so as to give guidance to designers of electrical appliances and electronic equipment and to ensure replacement of fuse-links by those of similar dimensions and characteristics, - to define methods of testing, - to define maximum sustained dissipation of fuse-links to ensure good compatibility of stated power acceptance when used with fuse-holders according to this document (see IEC 60127-6).
