The utility model can protect the high-voltage fuse while facilitating the rapid removal of the high-voltage fuse.

[0004] However, the above patent still has certain disadvantages when used: most of the existing protection devices for high-voltage fuses are used for centralized protection of a large number of fuses. Although they can be downwardly compatible with the storage protection of a smaller number of fuses, due to the limitations of the structure of the protection device, more empty spaces will appear inside the device, resulting in a waste of space. In addition, the device is large in size, which increases the floor space when protecting a small number of fuses, resulting in a reduction in transportation space. The overall use effect is not very good, and the practicability of the device is not ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

The expansion seats 7 are symmetrically installed at the top positions of the two side surfaces of the protective tube 1. The top position of the protective tube 1 is rotatably connected with a sealing cover 11. The middle position of one side surface of the sealing cover 11 is symmetrically rotatably connected with a connecting strip 9, and there are two groups of connecting strips 9. The end positions of the two groups of connecting strips 9 are respectively installed with a clamping shaft 8 and a clamping hoop 12. The connecting strips 9 and the connecting strips 9 can also be rotated through the clamping shaft 8 and the clamping hoop 12 to avoid the locking of the structure causing multiple groups of sealing covers 11 to fail to open synchronously.

[0031] In one embodiment, a bearing groove 5 is installed at the top position of the bearing plate 4, and a high-voltage fuse body 6 is clamped inside the bearing groove 5. The bearing groove 5 is provided to wrap and protect the high-voltage fuse body 6 to prevent it from colliding with the inner wall of the protective tube 1 and causing rupture. The bearing groove 5 can be made of rubber material.

[0032] In one embodiment, a base 19 is fixedly installed at the bottom of the protection tube 1, and the base 19 can enhance the stability of the protection tube 1 and improve the effect of use.

[0033] In one embodiment, the surface of the expansion seat 7 is provided with grooves for docking, and the grooves are arranged in an interlaced manner. The expansion seat 7 is arranged to realize the serial use of multiple protection tubes 1, expand the overall protection quantity, and enhance the use effect of the device.

[0034] In one embodiment, threaded holes 13 for bolt connection are provided on the surface of the expansion seat 7 . The threaded holes 13 are provided to facilitate the insertion of bolts to achieve the fastening operation of multiple expansion seats 7 .

[0035] In one embodiment, a pull plate 10 is installed at one side of the top of the sealing cover 11 . The provision of the pull plate 10 facilitates personnel to open and close the sealing cover 11 .

[0036] In one embodiment, holes are provided on the surface of the connection plate 2 for inserting the insertion rod 16 . The provision of the holes ensures that the insertion rod 16 can be smoothly inserted into the connection plate 2 , thereby achieving the purpose of connecting the structures.

[0038] Working principle: In actual use, personnel can choose a suitable number of protection tubes 1 according to the number of high-voltage fuses that need to be protected and stored. When the number involved is large, the protection tubes 1 can be connected through the expansion seats 7 on both sides of the top and fastened with bolts. At the same time, the movable plates 3 on both sides of the bottom can insert the connecting plate 2 into the limiting groove 17 on the other side, so that the plug rod 16 in the limiting groove 17 can plug and fix the connecting plate 2, so that the bottom supporting plate 4 for lifting the high-voltage fuse can be moved synchronously in batches during subsequent use, avoiding frequent operations caused by personnel moving one by one, and at the same time, the connecting strips 9 on the top of the sealing cover 11 can be clamped with each other, so that the clamp 12 at its end can be clamped on the clamping shaft 8. In this way, all the sealing covers 11 can be operated synchronously by opening the outermost sealing cover 11 later, which can also avoid repeated operations by personnel and improve the use effect of the equipment. When using a single number of protection tubes 1, only a single group of protection tubes 1 is needed, which can effectively avoid the waste of storage space and reduce idle space during transportation, improve the overall use effect of the device and the practicability of the equipment, and personnel can flexibly adjust between batch operation and single protection, which improves the overall flexibility of use and facilitates better use. Then, the protection operation can be normally realized by inserting the high-voltage fuse into the protection tube 1. The device as a whole has the advantages of diversified use forms, strong practicability and good use effect.
