Description

Technical Field

[0001] This utility model relates to the technical field of fuse insulation covers, specifically a drop-out fuse insulation cover. Background Technology

[0002] With the continuous improvement of the ecology, the activity range of wild animals (squirrels, birds, snakes, etc.) is constantly expanding. Power line faults caused by small animals occur from time to time, affecting the safe and reliable operation of power lines. Drop-out fuse insulation covers are a type of safety protection device used in power systems. They are mainly used to protect the exposed conductive parts of the fuse, preventing short circuits or electric shocks caused by accidental contact by personnel or animals. At the same time, they can also reduce the impact of environmental factors (such as rainwater, dust, etc.) on the fuse.

[0003] An insulating cover for a drop-out fuse, as disclosed in the authorization announcement number CN222233562U, includes an insulating bottle, a fuse tube, an upper terminal, and a lower terminal. The two ends of the fuse tube are connected to the upper terminal and the lower terminal, respectively. The two ends of the insulating bottle are connected to the upper terminal and the lower terminal, respectively. The insulating cover includes a deformable cover body, which is an insulating component. The cover body has a first half-cover and a second half-cover, and the cover body has an enclosed state and an unfolded state. Although the device has been tested in areas with high activity levels of small animals and locations of historical malfunctions, no small animal malfunctions have occurred at the testing sites to date, effectively preventing small animal malfunctions from happening. However, this does not solve the problem that existing fuse insulation covers are generally not easy to install with a snap-on locking mechanism to protect the fuse, making it easy for the fuse to be damaged accidentally, thus affecting the service life of the fuse insulation cover. It is also not convenient to make a sound to drive away small animals in the surrounding area, and the fuse is easily damaged by the influence of small animals, which affects the convenience of using the fuse insulation cover to drive away small animals in the surrounding area.

U-shaped grooves 24 are provided on the side wall of the right buckle 10. A gasket 15 is provided on the outside of the U-shaped groove 24. A nut 16 is provided on the outside of the gasket 15. The nuts 16 are threadedly connected to the threaded rod 14. When using a drop-out fuse insulation cover, the first outer shell 3 and the second outer shell 4 are positioned opposite each other, and are connected to form an insulation cover to provide insulation protection for the fuse's interior. When insulation protection of the fuse is required, the first outer shell 3 and the second outer shell 4 are fitted onto the position requiring protection. Supported by multiple sets of support columns 11 and the fuse, the first outer shell 3 and the second outer shell 4 are limited in position. The left latch 9 and the right latch 10 are respectively fitted onto the protrusions where the first outer shell 3 and the second outer shell 4 contact. Under the movable support of the rotating shaft 12, the left latch 9 and the right latch 10 rotate to fix the first outer shell 3 and the second outer shell 4. When holding the fuse, rotate the threaded rod 14. Under the movable support of the rotating shaft 13, the threaded rod 14 rotates to the surface of the U-shaped groove 24. Place the washer 15 on one side of the U-shaped groove 24 for limiting, so that the threaded rod 14 passes through the washer 15. Tighten the nut 16.
