Embodiment 2
[0019] The second embodiment of the fast recovery power fuse differs from the first embodiment only in the outer wall of the rotating cylinder, such as Figure 5 As shown, in the second embodiment, an annular groove 2100 , 2200 perpendicular to the metal bayonet 210 , 220 is respectively formed on the outer peripheral surface of the upper ring sleeve 21 and the lower ring sleeve 22 of the rotating cylinder 2 . Therefore, adjacent fuses 3 can be overlapped and connected in parallel by clamping conductive copper strips in the annular grooves 2100, 2200, thereby flexibly realizing the adjustment of the rated current of the line.

The invention provides a fast-recovery electric power fuse. The fast-recovery electric power fuse comprises a fixed pillar. The upper end and the lower end of the fixed pillar are respectively provided with an upper end wheel body and a lower end wheel body. Protruding ridges are uniformly arranged on the peripheries of the upper and lower end bodies, only the upper end wheel body and the lower end wheel body are respectively provided with one protruding ridge formed by a conductor, and the conductor protruding ridges on the upper end and the lower end are opposite to each other. The fixed pillar is fixed on power distribution equipment in an insulated manner. The conductor protruding ridges on the upper end and the lower end are respectively and electrically connected with a wiring column. The fuse further comprises a rotation barrel sleeving the periphery of the fixed pillar. The upper end and the lower end of the rotation barrel are respectively provided with an upper end ring sleeve and the lower end ring sleeve. Arc-shaped conductive spring sheets clamped among the protruding ridges of the upper and lower end wheel bodies are uniformly arranged on the peripheries of the inner walls of the upper and lower end ring sleeves. The adjacent arc-shaped conductive spring sheets are insulated from each other. Metal bayonets are uniformly arranged on the peripheries of the outer walls of the upper and lower end ring sleeves, and each metal bayonet is electrically connected with one arc-shaped conductive spring sheet. The pair of up-down opposite metal bayonets is internally provided with a fuse wire in a clamping manner. The fast-recovery electric power fuse is capable of rapidly repairing a circuit after the fuse wire is fused.
Description
technical field [0001] The invention relates to the field of power facilities, in particular, it is a power fuse. Background technique [0002] In the field of power facilities, a fuse is a basic power component, which is mainly used to quickly cut off the overloaded line by fusing itself when the line is overloaded. For the current fuse, it is necessary to disassemble and replace the fuse in the repair process after the fuse is blown. Fuse blowouts often occur, and for non-professional residents, the process of replacing the fuse is more troublesome. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a fast recovery power fuse, which can quickly repair the circuit after the fuse is blown. [0004] The technical solution adopted by the present invention to achieve the technical purpose is: the fast recovery power fuse includes a fixed base column, the upper and lower ends of the fixed base column are re...
