低压熔断器式隔离开关的应用

Application of Low-voltage Fuse Switch Disconnector

低压熔断器和低压断路器都是用于短路及过负荷保护的电气装置。近些年来,我国的民用建筑电气设计较多采用断路器,而一些经济发达的国家对熔断器和断路器的采用却基本是各占一半,究其原因,笔者做了一定的研究分析和归纳,对这两种保护装置的设计选用给出了一定的指导意见。并介绍了低压熔断器式隔离开关的应用。

Low-voltage fuse and low-voltage circuitbreaker are all the electrical devices used for the short circuit and overload protection. In recent years, the circuit-breaker is used more in the electrical design of civil buildings in our country, but the fuse and circuit-breaker are used half and half in those economy developed countries. To seek the reason, the authors have conducted some research, analysis and summary and give some guiding opinions for the design and selection of these two protection devices. Moreover, the low-voltage fuse switch disconnector is introduced.
