3. Structure Introduction
        Fuse from the base, the arc extinguishing devices and interrupters three major components. When the fuse in the closing position, dynamic and static contact by a compression spring-loaded to ensure that there is sufficient contact between the pressure arc tube lower end with a rotatable torsion spring, after the melt is loaded, the torsion spring namely tightening, so that the fuse in tension, in order to ensure arc tube self-locking in the closing position.
        When the circuit overload or short circuit when the melt blown fuse by means of a torsion spring, quickly pulled from the melting tube, and because a large amount of heat energy of the arc extinguishing gas into the melting tube, the arc extinguished quickly, in order to reduce arcing time and loss of extinguishing material. After arc extinction, melting tube under its own weight and the bridge-contact compression springs and the automatic drop to achieve visible fracture.
