Embodiment

[0022] refer to Figure 1-3 , a non-destructive circuit protection device, comprising a casing 1, two symmetrically arranged contact blocks 2 and a buffer box 3 are fixed on the inner wall of the casing 1, two symmetrically arranged contact pieces 4 are fixed on the inner wall of the buffer box 3, and the buffer The inner wall of the box 3 is connected with the connecting plate 6 through the connecting spring 5, and the connecting plate 6 is connected with the two connecting plates 4 in an even and sliding manner. The electric bag 7 is slidably connected with a shaking rod 8 , the buffer box 3 is provided with a slow-release mechanism, and the electric block 2 is provided with a trigger mechanism.

[0023] The trigger mechanism includes a pair of baffles 16 that are connected to the inner wall of the contact block 2 through torsion spring rotation. The end of the baffles 16 close to the shaking rod 8 is fixed with a piezoelectric block 9, and the inner top and inner bottom of ...

Abstract

The invention discloses lossless circuit protection equipment which comprises a shell, two symmetrically-arranged power connection blocks and a buffer box are fixed to the inner wall of the shell, twosymmetrically-arranged power connection pieces are fixed to the inner wall of the buffer box, and the inner wall of the buffer box is connected with a power connection plate through a connection spring. The power connection plate is in sliding connection with the two power connection pieces in a sealed mode, a pair of power connection bags is embedded in the inner wall of each power connection block, the two pairs of power connection bags are jointly in sliding connection with a jitter rod, a slow release mechanism is arranged in the buffer box, and a trigger mechanism is arranged in each power connection block. The equipment has the advantages that: by arranging the power connection bags, the position of the jitter rod is ensured, so that the jitter rod effectively moves on the surface of the jitter rod and is not easy to disengage and misplace, the power connection stability is ensured, the jitter rod can deform to a certain extent, the jitter rod can be effectively coated, and thecondition of poor contact is avoided; and meanwhile, unnecessary abrasion can be reduced, so that the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of circuit protection, in particular to a non-destructive circuit protection device. Background technique [0002] With the increase of electrical equipment, the load of the electrical line is getting bigger and bigger, and in the existing line connection, the overload and short circuit of the line will directly affect all the electrical equipment in the line, so it is necessary to overload the line and short circuit protection; [0003] Existing protection devices are generally fuses, which basically can only protect against overload, some can be automatically restored, and some cannot be automatically restored, and fuses will basically cause their own damage, either by replacing the fuse or damaging the hot metal sheet, resulting in The life of the whole is limited, and it is generally impossible to realize the automatic recovery of overload and the short circuit is completely interrupted. The overall fun...
