Blowing phenomenon of automobile fuse

Fuses are often used in automobile circuits and will not blow under normal circumstances. However, if there is a short circuit or poor grounding fault in the circuit, the fuse will blow. In this way, the circuit controlled by the fuse will be open, and the electrical equipment will not work normally. The function of automobile fuse is to protect the circuit from being burned out. Once the fuse is blown, the control circuit will not work, that is to say, if the circuit of engine operation is involved, the engine may not work. Generally, there is no fault light when the automobile fuse is blown, but once the electrical equipment controlled by the fuse fails, the power consumption increases or the start-stop frequency exceeds the normal use rule, it may lead to fuse blowing. Especially for electrical equipment with large starting current (such as motors, etc.). ), frequent starting may be one of the reasons for fuse blowing. Therefore, when maintaining the car, we need to check whether the fuse is normal regularly to ensure the safety and stability of the circuit and avoid traffic accidents caused by fuse failure.
