Embodiment 1
[0020] please combine figure 1 As shown, this embodiment discloses a fuse assembly, including an adjustable fuse 100, a control system 200, a current Hall sensor 300, and a holder 400 made of insulating material. The adjustable fuse 100 includes an insulating carrier 1 , a fuse wire 2 fixed on the insulating carrier 1 , and a sliding contactor; the fuse wire 2 extends along the length direction of the insulating carrier 1 . Both ends of the insulating carrier 1 are fixed on both ends A and B of the holder. And in this embodiment, the fuse wire 2 is spirally wound on the insulating carrier 1 . The sliding contactor has contacts in contact with the fuse 2 , which are moved back and forth along the length of the insulating carrier 1 to make contact with different positions of the fuse 2 . The fuse wire 2 is a bare fuse body with no insulating layer on the outer surface. When the fuse wire 2 is wound on the insulating carrier 1, the spacing of the fuse wire 2 needs to be matched...
Embodiment 2
[0025] This embodiment is the control method of the fuse assembly in the above-mentioned first embodiment. In the control method: the current value signal detected by the current Hall sensor 300 is transmitted to the control system; When the current value signal does not meet the fusing requirements, the joints 5 and 6 of the sliding contactor are controlled to slide so that the fusing current reaches the preset fusing requirements.
[0026] However, as in the first embodiment, when the fuse assembly includes at least two adjustable fuses 100, the two adjustable fuses are set to different fusing currents. When one adjustable fuse is blown, the other adjustable fuse is blown. The fuse is still connected, so that the overall circuit connection is not interrupted.
[0027] When an adjustable fuse is blown, the joints 5 and 6 of the sliding contactor are controlled to move to both ends of the unblown fuse 2, that is, the fused part between the joints 5 and 6 is avoided and the unf...
Embodiment 3
[0029] The third embodiment provides an adjustable fuse, which is an independent adjustable fuse in the first embodiment. The independent adjustable fuse can be manufactured and used as a product alone, and can be adjusted manually or automatically. The position where the joint of the sliding contactor is in contact with the fuse wire enables the selection of different rated fuse currents. Since the adjustable fuse in this embodiment is exactly the same as the adjustable fuse in the first embodiment, it will not be repeated here.
