标准摘要
[中文适用范围]: 范围和目标 IEC 60871 的这一部分适用于内部熔断器,其设计用于隔离故障电容器元件@,以便允许该电容器单元的其余部分以及连接该电容器单元的组运行。此类熔断器不能替代断路器等开关装置,也不能替代电容器组或其任何部分的外部保护。 IEC 60871 本部分的目的是制定有关性能和测试的要求,并为熔断器保护的协调提供指南。 [外文原描述]: IEC 60871-4:2014 applies to internal fuses which are designed to isolate faulty capacitor elements, in order to allow operation of the remaining parts of that capacitor unit and the bank in which the capacitor unit is connected. Such fuses are not a substitute for a switching device such as a circuit-breaker, or for external protection of the capacitor bank or any part thereof. The object of this part of IEC 60871 is to formulate requirements regarding performance and testing and to provide a guide for coordination of fuse protection. This second edition cancels and replaces the first edition published in 1996. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: The disconnecting requirements have been modified. Keywords: internal fuses, faulty capacitor elements, fuse protection
