1. It is voltage instability, which can cause electrical power frequency variation and result in frequency variation of the current passing through the fuse, causing the fuse to burn out.
2. It is due to the excessive use of electrical appliances with high power, exceeding the ability of fuses to pass current normally.
3. It was your place that underwent power line renovation, which allowed for an increase in current, but you did not replace the fuses with thicker ones accordingly.
4. It's just that the fuse itself is aging, used for too long, and passes through current for a long time. As we all know, fuses also have a certain resistance, so when passing current, they will heat up, become thinner and thinner, and the resistance will become larger and larger, ultimately leading to burnout. In addition, fuses may become thinner during long-term storage due to friction, slow air oxidation, and other reasons.
1. You can first use the appliances separately, that is, turn them on one by one to see. If each appliance works normally and the fuse is not blown when used alone for a long time, it means that all appliances are working normally and there is no problem. However, when using appliances at the same time, the fuse will burn out, indicating that the load is exceeded. You can replace the fuse appropriately by bolding it. But it's best to find an electrician to help replace the appropriate fuse. Fuses that are too thin or too thick are not conducive to protecting home appliances and power sources.
2. If the fuse burns when using any of these appliances alone, it may indicate that the appliance is faulty and should be checked by a professional electrical repairman.
