3. Structure Introduction
Fuse is made of two parts of the base, the arc extinguishing device component. Initiative, designed to bridge the static contact structure. 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 quickly extinguished, the voltage across the restored, after arc extinction, melting tube under its own weight and the bridge contact compression springs and the automatic drop to achieve visible fracture, and the arc is designed to Zhuji exhaust.
