标准摘要
[中文适用范围]: IEC 60282 的这一部分规定了设计用于室外或室内 50 Hz 和 60 Hz、额定电压超过 1 000 V 的交流系统的驱逐熔断器的要求。驱逐熔断器是通过驱逐效应熄灭电弧的熔断器。电弧产生的气体。喷射熔断器根据 TRV(瞬态恢复电压)能力分为 A 类和 B 类。本标准仅涵盖熔断器的性能,每种熔断器均由熔断器座、熔断器载体和熔断体的指定组合组成,这些组合已通过按本标准进行测试;本标准不能暗示其他组合的成功性能。该标准也可用于非驱逐保险丝,其中中断过程等待自然电流为零以清除电路。注 1:有关熔断器等级选择的具体信息,请参阅第 5 条和第 12 条。注 2:保护电容器和变压器电路应用所需的熔断器须满足附加要求(参见 IEC 60549 [1]1 或 IEC 60787 [2])。注 3:本标准不包括负载开关或故障产生能力。有关开关功能要求的信息可在 IEC 60265-1 [3] 中找到。注4:本标准不包括与噪声水平有关的方面,也不包括某些类型的排出熔断器在故障电流中断过程中固有的热气体排放的问题。 [外文原描述]: IEC 60282-2:2008 provides requirements for expulsion fuses designed for use outdoors or indoors on alternating current systems of 50 Hz and 60 Hz, and of rated voltages exceeding 1 000 V. The main changes with regard to the previous edition include: - Class C has been eliminated; - TRV values have been reviewed and, where appropriate, harmonized with IEC 62271-100:2001, its amendment 1 (2002) and amendment 2 (2006); - tests for non-ceramic insulators have been included; - a lightning surge impulse withstand test for fuse-links has been included; and - an homogeneous series has been redefined.
