标准摘要
[中文适用范围]: 供授权人员使用的熔断器通常设计用于仅授权人员可接触熔断体并可由授权人员更换熔断体的装置。除非本标准另有规定,授权人员根据以下熔断器系统使用的熔断器也符合 IEC 60269-1 相应子条款的要求。本标准分为熔断器系统,每个熔断器系统涉及供授权人员使用的标准化熔断器的具体示例: 熔断器系统 A:带插片式熔断器的熔断器(NH 熔断器系统) 熔断器系统 B:带撞针熔断器的熔断器带插片触点(NH 熔断器系统) 熔断器系统 C: 熔断器导轨(NH 熔断器系统) 熔断器系统 D: 用于母线安装的熔断器底座(NH 熔断器系统) 熔断器系统 E: 带用于螺栓连接的熔断体的熔断器(BS 螺栓连接)熔断器系统 F:熔断器带圆柱形触头盖熔断体(NF 圆柱形熔断器系统) 熔断器系统 G:熔断器带偏置片状触点(BS 夹式熔断器系统) 熔断器系统 H:带熔断器的熔断器- 具有“gD”和“gN”特性的熔断体(J 类和 L 类延时和非延时熔断器类型) 熔断器系统 I:带有楔形紧固触点的 gU 熔断器 熔断器系统 J:带有具有“gD”熔断器的熔断器CC 类”和“gN CC 类”特性(CC 类延时和非延时熔断器类型) [外文原描述]: IEC 60269-2:2010 provides fuses for use by authorized persons are generally designed to be used in installations where the fuse-links are accessible to, and may be replaced by, authorized persons only. This standard is divided into fuse systems,(A thru I), each dealing with a specific example of standardized fuses for use by authorized persons. This fourth edition of IEC 60269-2 cancels and replaces the third edition published in 2006 and constitutes a minor revision. This part is to be used in conjunction with IEC 60269-1:2006, Low-voltage fuses - Part 1: General requirements and its Amendment 1 (2009). This Part 2 supplements or modifies the corresponding clauses or subclauses of Part 1. Where no change is necessary, this Part 2 indicates that the relevant clause or subclause applies. Tables and figures which are additional to those in Part 1 are numbered starting from 101. Additional annexes are numbered AA, BB, etc. This publication is to be read in conjunction with IEC 60269-1:2006 .
