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 in the closing position of the lock.
When the circuit overload or short circuit when the melt blown fuse by means of a torsion spring, quickly pulled from the melting tube, while a large amount of heat energy of the arc extinguishing gas into the melting tube, the arc extinguished quickly, and to reduce the arcing time extinguishing material losses. After arc extinction, melting tube under its own weight and the bridge contact compression spring action, automatic drop, achieve significant fracture.
And the arc tube designed to progressively vented gases produced when breaking a small current is discharged from the lower end of the exhaust port, when breaking a large current, gas rushed to open the upper cap, the realization, the lower end of the exhaust port at the same time exhaust to meet on the same fuse carve off the current requirements of different sizes.
