Remove the fuse element, apply an axial tension of 60 N to it, and after maintaining for 30 minutes, no damage is found.

[0019] The fixing mechanism includes a second hydraulic cylinder 14, a clamping block 15, and a fixing frame 16. The second hydraulic cylinder 14 is fixedly connected above the interior of the cabinet body 1. The output end of the second hydraulic cylinder 14 is fixedly connected with the clamping block 15. A fixing frame 16 is provided below the clamping block 15. One end of the connecting frame 10 on the outer side of the fuse 5 is provided with a T-shaped structure. The shape of the fixing frame 16 is an H-shaped structure. The shape of the clamping block 15 is an L-shaped structure. Place the connecting frame 10 on the outer side of the fuse 5 on the fixing frame 16. The output end of the second hydraulic cylinder 14 drives the clamping block 15 to move downward. The clamping block 15 and the fixing frame 16 cooperate to clamp the connecting frame 10, so as to fix the fuse 5 inside the cabinet body 1. When the mechanical test of the fuse 5 is completed, the output end of the second hydraulic cylinder 14 drives the clamping block 15 to move upward, and the clamping block 15 no longer clamps the connecting frame 10, so as to take out the fuse 5 from the interior of the cabinet body 1.

[0020] The experimental mechanism includes a hinge seat 7, a first hydraulic cylinder 8, and a connecting seat 9. One end of the bottom plate 6 is provided with a hinge seat 7.

[0022] Unscrew the nut on the connecting bolt, adjust the position of the first hydraulic cylinder 8 so that the ring enters the inside of the connecting seat 9, then insert the connecting bolt into the ring, and then tighten the nut on the connecting bolt to connect the ring and the connecting seat 9 together. The first hydraulic cylinder 8 can drive the connecting seat 9 to perform telescopic movement to drive the fusing piece on the fuse 5 to automatically open and close, saving experimental time and increasing efficiency. Moreover, the first hydraulic cylinder 8 is hinged to the bottom of the cabinet body 1 through the hinge seat 7, and the first hydraulic cylinder 8 can rotate following the fusing piece to avoid interfering with its rotation.

The top end of the rotating rod 13 is hinged to one side of the first hydraulic cylinder 8. The top of the slider 12 is hinged to the first hydraulic cylinder 8 through the rotating rod 13. When the first hydraulic cylinder 8 rotates, it drives the slider 12 to slide on the slide rail 11 through the rotating rod 13. The nylon sleeve can increase the friction force between the slider 12 and the slide rail 11, so that the slider 12 will not move by itself due to other external forces. The slider 12 and the first hydraulic cylinder 8 play a supporting role through the rotating rod 13.

[0024] For this automatic mechanical test device for the fuse, unscrew the nut on the connecting bolt, adjust the position of the first hydraulic cylinder 8 so that the ring enters the inside of the connecting seat 9, then insert the connecting bolt into the ring, and then tighten the nut on the connecting bolt to connect the ring and the connecting seat 9 together. The first hydraulic cylinder 8 can drive the connecting seat 9 to perform telescopic movement to drive the fusing piece on the fuse 5 to automatically open and close, saving experimental time and increasing efficiency; the top of the slider 12 is hinged to the first hydraulic cylinder 8 through the rotating rod 13. When the first hydraulic cylinder 8 rotates, it drives the slider 12 to slide on the slide rail 11 through the rotating rod 13. The nylon sleeve can increase the friction force between the slider 12 and the slide rail 11, so that the slider 12 will not move by itself due to other external forces.
