The role and function of the fuse

effect

The fuses invented by Edison more than a hundred years ago were used to protect the expensive incandescent lamps at that time. With the development of the times, fuses protect electronic/electrical equipment from overcurrent/overheating, and also avoid electronic equipment caused by internal faults. Serious injury.

basic skills

Electrical performance: The fuse is connected in series in the electronic circuit. Generally, the resistance is small (the power consumption is small). When the circuit works normally, it is only equivalent to one wire, which can stably turn on the circuit for a long time; When external disturbance occurs and current fluctuates, it should also be able to withstand a certain range of overload; only when a large overload current (fault or short circuit) occurs in the circuit, the fuse will operate, and the circuit is safe by disconnecting the current.

Safety: During the process of breaking the circuit of the fuse, due to the existence of the circuit voltage, an arc will occur in the gap of the melt disconnection. High-quality fuses should avoid this arcing as much as possible; after the fuse is broken It should be able to withstand the circuit voltage applied at both ends
