Selection of Fuses in Small Home Appliance PCB Board
The Fuses commonly used in PCB boards of small household appliances use self-recovery fuses to protect the circuit. The selection of self-recovery fuses in small household appliances can be divided into the following steps:
Firstly, determine the working voltage of the self-recovery fuse;
2. Based on the actual average operation of different products, determine whether the self-recovery fuse is the inactive current;
3. The maximum current ratio, temperature, and other parameters of household small appliances in actual work, as well as the time required for self-recovery fuse self-correction (self-recovery fuse action current amplification or reduction);
4. Revise it to an actual experiment and ensure that there is no false protection work, but it is necessary to self-recover the fuse parameters within the specified time and protect the motor from stalling. The change in the thermistor of a small motor is an easy choice, but after repeated experiments, the thermal resistance of the motor varies significantly
During the experiment, self-restore the resistance value of the fuse to determine the upper and lower limits.
