The role of the fuse

Publish Time: Author: Site Editor Visit: 52

Fuses are also called current fuses. Mainly to play the role of overload protection. Its working principle is to correctly install the fuse in the circuit. When the current abnormally rises to a certain height and heat, the fuse will fuse itself and cut off the current to protect the safe operation of the circuit.

Fuse

Application

The fuse can cause the current to rise continuously when the circuit fails, such as a short-circuit problem, which leads to the damage of the circuit, and it also affects other electrical appliances in the home. If it is not found in time, it will cause more serious fire accidents. But if the fuse is installed, as long as the current is abnormal and unstable, the temperature will reach a certain height, the fuse will be blown, thereby cutting off the entire circuit, which can play a good protective role.

Replace the fuse

Then know the function of the fuse, and then I will teach you how to replace the fuse. First, we need to find the switch of the master knife, and observe whether the fuse is blown, then wear insulating gloves, rubber gloves and other safety measures, and prepare a spare fuse. Power off the main brake, remove the melted fuse with pliers, then replace it with a new spare fuse, and tighten the screw part with a tool (screwdriver). At this point, the replacement has been completed.
