摘要
文中列举了一起并联电容器组外熔断器群爆故障,分析了喷逐式熔断器结构特征与工作原理,阐述了熔断器产生群爆的多种原因,并重点围绕熔断器安装角度不合理和熔断器内灭弧管受潮等主要原因进行分析,并提出了预控措施。
In this paper, a fault of external fuse group explosions in shunt capacitor bank is presented, analysis of capacitor bank is introduced. The structure feature and operating principle of the spray type fuse is analyzed. Different causes resulting in external fuse group explosions are expounded such as unreasonable installation angle and moisture of arc interrupting tube of the fuse. The corresponding preventive measures are proposed.
