Why do we need to add a fuse to the circuit?
If there is no fuse in the line, then once the circuit is overloaded or a short circuit occurs, the current in the loop will inevitably increase, so that when the current flowing through the wire exceeds the carrying current of the wire, the wire will overload and heat up, melting the wire insulation layer and copper wire , or even spontaneous combustion, causing safety accidents (car burning). The natural phenomenon of wires is shown in the figure below:

After clarifying the causes and consequences of spontaneous combustion of wires, we have to ask, how to avoid the problem of spontaneous combustion of wires?
The fuse is produced in such a situation. In order to avoid the spontaneous combustion of the wire, we hope that there is a component that can detect the overcurrent and short-circuit current in the circuit before the wire burns, and can respond quickly to interrupt the circuit quickly. (the fuse is blown), thereby achieving the purpose of protecting the wire.
Such a component that protects wires in a circuit is what we call a fuse, or 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 placed as close to the power supply as possible, as shown in the figure below. If the distance is too far, you need to consider setting up higher-level insurance.
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 principle of the fuse is that when the circuit is short-circuited, it can be blown in time when the wire smokes and catches fire, so as to cut off the circuit and prevent the wire from burning and causing the entire vehicle to spontaneously ignite.
The specific working principle of the fuse is as follows:
The fuse has a certain resistance, and the conductor will generate heat when current flows. As time increases, the heat generation increases, and the current and resistance also increase the heat generation speed. The structure and installation of the fuse determine the heat dissipation speed.
