Fuse Application Field and Working Principle

Fuses are an important component of current protection, which can cut off the fault circuit in time and protect the normal operation of electrical circuits.Their application fields and working principles are explained as follows.

Application Fields

Fuses can be widely used in low- and medium-voltage distribution systems of electric power systems, industrial and mining production equipment, ground fault detection system of railway electrification, and various household and commercial electrical appliances. In order to prevent overload and short circuit, the fuse link installed in motor, transformer, gate circuit break, generating set, distribution line and industrial unit correctly will play its role. Meanwhile, in order to meet special requirements of some equipment, fuses with other characteristics are also produced.

Working Principle

Fuses are special short-circuit protection components that protect electrical components from the damage caused by overload and short circuit. When the meltable metal or metal braid melts, it can pass current through a large area directly, and then the wire can instantly cut off the circuit.

If the current is larger than the rated current of the fuse, and the meltable metal or metal braid is heated to the fusing temperature due to the current, the atmospheric pressure melts the metal conductor and increases its area, making it easier to conduct electricity and current. The current doubles the melting area, and finally the fuse is blown. Therefore, the fuse can cut off the fault circuit in time and protect the normal operation of electrical circuits.
