Working principle of self recovery fuse.battery charger fuse

　　In this link, the components that can block the oscillating current are usually fuses, but the general fuses are only disposable. If self recovery fuses are used, then the instruments in this type of circuit can be used for Test effort. And this type of function can be guaranteed not only by self recovery fuses, but also by some temperature sensors. However, these electronic components are far from fast in terms of reflection time compared to self recovery fuses. Therefore, for circuits with high-precision instruments, if some temperature sensors are applied, the oscillating current can burn out the instrument before the resistor blocks the power circuit.

　　The function of a self restoring fuse is to provide overcurrent protection in the power circuit. A circuit with a high-precision instrument must have a fuse to maintain the safety of the high-precision instrument. However, if human factors are often used to remove and replace fuses during frequent use, it is not specific, which is why self restoring fuses are put into use. It can automatically connect the circuit current, eliminating the need for manual fuse replacement, which greatly increases work efficiency.

　　Overcurrent protection refers to the entire process of maintaining important instruments by blocking the oscillation current by some electronic components before damaging them, as many electronic products have a rated voltage and are not allowed to exceed the rated voltage, otherwise the machine equipment will be burned. In this link, the components that can block the oscillating current are usually fuses, but the general fuses are only disposable. If self recovery fuses are used, then the instruments in this type of circuit can be used for Test effort.

　　Allowing the self restoring fuse to provide overcurrent protection to the circuit without damaging the basic instrument will provide peace of mind in the application of the instrument. And this type of function can be guaranteed not only by self recovery fuses, but also by some temperature sensors. However, these electronic components are far from fast in terms of reflection time compared to self recovery fuses. Therefore, for circuits with high-precision instruments, if some temperature sensors are applied, the oscillating current can burn out the instrument before the resistor blocks the power circuit.
