快速熔断器：快速熔断器主要用于半导体整流元件或整流装置的短路保护。由于半导体元件的过载能力很低

。只能在极短时间内承受较大的过载电流，因此要求短路保护具有快速熔断的能力。快速熔断器的结构和有

填料封闭式熔断器基本相同，但熔体材料和形状不同，它是以银片冲制的有V形深槽的变截面熔体。

保险丝(fuse)也被称为电流保险丝，IEC127标准将它定义为"熔断体（fuse-link)"。其主要是起过载保护作用。

电路中正确安置保险丝，保险丝就会在电流异常升高到一定的高度和热度的时候，自身熔断切断电流，保护了

电路安全运行。 

Fuse is also known as current fuse, and IEC127 standard defines it as "fuse-link". It mainly plays the 

role of overload protection. When the fuse is properly placed in the circuit, the fuse will cut off the 

current when the current is raised to a certain height and heat, and the safety of the circuit will be 

protected. More than 100 years ago, the fuse invented by Edison was used to protect the expensive 

incandescent lamps. With the development of the times, the fuse protected the power equipment 

from the damage caused by the overheating of the electric current, and avoided the serious damage 

caused by the internal failure of the electronic equipment.
