When an overcurrent occurs in the circuit, the fuse will fuse and generate an arc.
When an overcurrent occurs in the circuit, the fuse will fuse and generate an arc. At this time, the gas generating material of the arc extinguishing tube lined by the molten tube generates high-pressure jet gas under the action of the arc to blow out the arc. At the same time, after the fuse is blown, the upper and lower moving contacts of the fuse tube lose the fastening force of the fuse. Under the action of the gravity of the fuse tube itself and the spring pieces of the upper and lower static contacts, the fuse tube drops rapidly, causing the circuit to be disconnected and the faulty section line or faulty equipment to be removed.
