s12, circulating the steps S9-S11 to finish the recovery installation of the six-group connecting seat 104; by preparing the two groups of inner rotating blocks 101, the inner rotating blocks 101 can be recycled, and when the fuse wire 14 in the inner rotating blocks 101 is completely fused, only part of the fuse wire 14 needs to be replaced, so that the replacement of the whole fuse-type protection device is avoided, the replacement cost is effectively reduced, and meanwhile, the recovery and utilization of the fuse wire 14 of the broken part are facilitated;
s13, inserting the positioning shaft 108 of the inner rotating block 101 into the mounting hole of the top pressing block 82, adjusting the inner rotating block 101, controlling any component connecting seat 104 of the inner rotating block to face downwards, and pressing the top pressing spring 83 to enable the positioning electrode rod 107 to be inserted into the clamping groove 81, wherein the adjusting toothed ring 102 is meshed with the adjusting worm 7, the first electrode block 91 is electrically connected with the positioning electrode rod 107, and the second electrode block 92 is electrically connected with the movable electrode rod 105;
s14, installing a cover plate 4, and fixing the cover plate 4 and the shell 1 through bolts; arrange fuse-type protection part structure in mounting groove 5 of casing 1 to seal fixedly through apron 4, make whole fuse-type protection part structure and main part circuit separation, effectively avoid the influence of external environment factor, avoid outside dust to influence the device's guard action, guarantee the device's result of use.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
