IEC 60143-3:20 15适用于设计用于隔离故障电容器元件的内部熔断器，以允许电容器单元的剩余部分和电容器单元所连接的组的操作。这种熔断器不能替代诸如断路器的开关装置，或用于电容器组或其任何部分的外部保护。IEC 60143本部分的目的是: -制定有关性能和测试的要求； -为保险丝和银行保护的协调提供指南。这第二版取消并取代了1998年出版的第一版。本版构成技术修订版。与上一版相比，该版本包括以下重大技术变化:测试程序已大大简化。 关键词:故障电容元件熔断器和银行保护

IEC 60143-3:2015 applies to internal fuses designed to isolate faulty capacitor elements, 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 60143 is:
- to formulate requirements regarding performance and testing;
- to provide a guide for coordination of fuse and bank protection. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: The test procedure has been largely simplified. Keywords: faulty capacitor elements, fuse and bank protection
