The operation process is as follows: when the lead is mounted, since the hinge 107 enables the first fixing plate 101 and the second fixing plate 102 to rotate relatively, therefore, the second fixing plate 102 is rotated to separate the first fixing plate 101 from the second fixing plate 102, at this time, the lead is placed in the wire inlet/outlet 102-2 located at the inner side of the arc protrusion 102-1, the second fixing plate 102 is rotated again to attach the first fixing plate 101 to the second fixing plate 102, the first screw 105 provided in the first through hole 104 and provided on the first fixing plate 101 and the second fixing plate 102 are matched with the first nut 106 which is screwed on one end of the first screw 105 passing through the first through hole 104, the first fixing plate 101 and the second fixing plate 102 are locked, so that the lead is directly connected into the drop-out fuse wire clamp, the installation workload is reduced, the material is saved, and more, the power failure accident and the safety accident caused by the fault of the equipment wire clamp are solved.
In the using process, the bearing unit 200 and the wire clamp unit 100 are connected with each other through the first connecting plate 201, and the insulator 202 in the bearing unit 200 forms good insulation between the device and the ground, so that the device is protected, and meanwhile, the device is firmly fixed through the mutual matching among the supporting plate 203, the base 204, the first limit hole 205, the limit screw 206 and the second nut 207 in the bearing unit 200, and the safety of the device in the using process is ensured.
When short-circuit current is fused through a fuse wire, an electric arc is generated, a large amount of gas is generated by a steel paper tube lined in a fuse tube 304 under the action of the electric arc, the gas is sprayed out towards the lower end to blow out the electric arc, the upper moving contact and the lower moving contact of the fuse tube 304 lose the fastening force of the fuse wire due to the fact that the fuse wire is fused, the fuse tube rapidly falls under the action of the gravity of the fuse tube, the upper static contact and the lower static contact spring pieces, a circuit is disconnected, a fault section circuit or fault equipment is cut, and therefore the circuit is protected.
