Due to the low overload capacity of semiconductor components and the inability to withstand large currents in a short period of time, it is necessary to use a professional fast fuse. Fast fuse can be used as a short-circuit protection device for semiconductor rectifier components or rectifier devices, so what are the characteristics of a six-part fast fuse? Look at my analysis below:
With anti-delay ability;
What is the anti-delay feature? In other words, if the overload current is small, the fusing time is long, and the overload current is large, and vice versa. Therefore, when it is within a certain range of overload current or overload time, the fast fuse can continue to be used because it has different fusing characteristic curves and has a wide range of applications;
With current limiting characteristics;
The melt of the fast fuse has a rectangular sheet with a narrow round hole, and there is a quartz sand arc extinguishing medium inside. When a short-circuit fault occurs, because the fault current does not achieve the expected short-circuit current effect, it will be fused, so that the arc will be divided into multiple small segments by the quartz sand, which can not only limit the increase of the short-circuit current, but also accelerate the extinguishment of the arc;
Have breaking capacity;
When the electronic component has a short circuit fault, the fast fuse will first blow the narrow neck of the round hole, and then the arc inside will be divided into many small sections by the part quartz sand in the fast fuse, so that the arc will be extinguished; the quartz sand is an insulator, so When the arc is extinguished, the fast fuse will become an insulator, cutting off the circuit;
Has a current limiting effect;
When the electronic components have a short circuit failure, the impact capacity of the load equipment will be smaller, because the fast fuse can be cut off in a short time and has a good current limiting effect;
These are the four main features of fast fuse. There are too many types of fast-acting fuses on the market, but consumers should proceed from their own requirements and buy high-quality fast-acting fuses. The cost-effective fast fuse has high sensitivity and fast fusing speed, which can protect electronic components.
