Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric power construction protection tools, in particular to a drop-out fuse shielding cover. Background Art
[0002] The drop-out fuse is installed on the branch line of the 10kV distribution line, which can reduce the scope of power outage. Because it has an obvious disconnection point and has the function of an isolating switch, it creates a safe working environment for the maintenance section lines and equipment. It is the most commonly used short-circuit protection switch for 10kV distribution line branch lines and distribution transformers. When the drop-out fuse needs to be replaced or repaired, the outside of the drop-out fuse needs to be insulated and shielded in advance to avoid large electric sparks generated by the drop-out fuse when the leads at both ends are removed, in order to protect power personnel. At present, the drop-out fuse shielding cover adopts a splint structure to wrap around the outside of the drop-out fuse, and uses a clip to clamp and fix the edge opening of the shielding cover. This fixing method is not stable and can easily cause the shielding cover to fall off. There is an operational risk and needs to be improved. Therefore, we propose a drop-out fuse shielding cover.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0017] Embodiment 1, as Figure 1-2 As shown, the utility model provides a technical solution: a drop-type fuse shielding cover, including a cover body 1 and a cover body 2, the cover body 1 is fixedly connected to one end of the cover body 2, a convex shell 4 is arranged on the surface of the cover body 1 facing the side of the cover body 2, a through hole 5 is opened at the center of the convex shell 4, a convex shell 2 9 is arranged on the surface of the cover body 2 away from the cover body 1, a through hole 2 8 is opened at the center of the convex shell 2 9, an insertion rod 7 is hung on the surface of the cover body 1 through a rope body 6, and the rope body 6 can limit the position of the insertion rod 7 to prevent the insertion rod 7 from falling and being lost easily.
[0018] In a specific embodiment of the present utility model, the cover body 1 and the cover body 2 are made of orange-red elastic rubber material as a whole, and a hanging ring 2 is provided for hanging the shielding cover as a whole in cooperation with the hook body. When in use, the cover body 1 and the cover body 2 are directly covered on the outside of the drop-out type fuse as a whole, and then the convex shell 1 4 is inserted into the convex shell 2 9. Due to the provision of the convex strip 401, the assembly of the convex shell 1 4 when inserted into the convex shell 2 9 is an interference assembly, which improves the stability of the convex shell 1 4 and the convex shell 2 9 when they are matched. In order to further improve the stability of the convex shell 1 4 and the convex shell 2 9 when they are matched, the insertion rod 7 can be passed through the through hole 1 5 and the through hole 2 8 in turn. The insertion rod 7 is in friction contact with the through hole 1 5 and the through hole 2 8, which can enhance the stability of the cover body 1 and the cover body 2 when they are covered on the outside of the drop-out type fuse and reduce the probability of the shielding cover falling off as a whole.
[0019] In the preferred technical solution, the number of convex shell 1 4, convex shell 2 9 and insertion rod 7 are all two. The convex shell 1 4 and convex shell 2 9 at the same horizontal height are aligned front and back. The outer surface contour size of the convex shell 1 4 is consistent with the inner surface contour size of the convex shell 2 9. The outer surface of the convex shell 1 4 is fixedly provided with a plurality of convex strips 401. The thickness of the convex strips 401 is 2 mm. The convex shell 1 4 is inserted into the convex shell 2 9. Due to the provision of the convex strips 401, the assembly when the convex shell 1 4 is inserted into the convex shell 2 9 is an interference assembly, which improves the stability of the convex shell 1 4 and the convex shell 2 9 when they are matched.
[0020] In the preferred technical solution, the inner diameters of through hole 1 5 and through hole 2 8 and the diameter of the plug rod 7 are consistent with each other. The plug rod 7 is passed through through hole 1 5 and through hole 2 8 in sequence. The plug rod 7 is in friction contact with through hole 1 5 and through hole 2 8, which can enhance the stability of the cover body 1 and the cover body 2 2 when they are covered on the outside of the drop-out fuse.
[0021] In the preferred technical solution, a hanging ring 3 is fixedly provided at the center position of the top of the cover body 1 and the cover body 2, and the hanging ring 2 is provided to cooperate with the hook body to hang the entire shielding cover.
[0022] To summarize, this embodiment makes local structural improvements based on the appearance structure of the traditional drop-type fuse shielding cover, and designs a snap-fit structure and a plug-in fixing structure to ensure the stability of the shielding cover when it is assembled on the drop-type fuse. Compared with the fixing method of using clips to clamp the edge of the traditional drop-type fuse shielding cover, the snap-fit structure and plug-in fixing structure of this embodiment have higher stability and are easy to disassemble.
