摘要
从对BRw□型喷逐式熔断器熔断体所受拉力和分断运动的理论分析可得出拉力、开断弹簧固有振动基频和断口距离的计算公式,并通过试验验证.这些公式在研究熔断器性能和设计计算方面是必要的.熔断器应有足够高的分断速度才能在分断容性电流时避免重击穿.
This paper presents the theoretical calculation method for the pulling force of fuse-link and the breaking characteristics of type BRW □-6 fuse. Some expressions are derived for calculating the pulling force, the fundamental frequency of intrinsic vibration of spring and breaking length. These expressions are useful in performance study and design of a fuse. The breaking speed has a significant influence on the capacitive breaking behaviour on these fuses. A high breaking speed is required to avoid the re-strike.
