Such a component that protects the wires in the circuit is what we call a fuse, or a fuse. A fuse is a thermally responsive device that is intentionally designed and manufactured to be the weakest part of the line in order to protect the wiring harness, and it is an electrical component that protects the wires. It is worth mentioning that in the circuit, the fuse can only protect the wire after the fuse, so the fuse should be installed as close to the power supply as possible. If the distance is too far, it is necessary to consider setting up a higher-level fuse.
How does the fuse protect the circuit, and what is the working mechanism of the fuse?
Understand why a fuse is added to the circuit, and actually have a clearer understanding of the working mechanism of the fuse. It is very important to understand the main function and working mechanism of the fuse for the matching design of the fuse.
The working mechanism of the fuse is that when the circuit is short-circuited, it can be fused in time when the wire smokes and catches fire, so as to cut off the circuit, prevent the wire from burning, and cause the vehicle to spontaneously ignite.
