For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example 1

[0043] This embodiment provides a drop-out type fuse insulation cover, see Figure 1 The drop-out fuse includes an insulating bottle 10, a fuse tube 20, an upper pile head 30, a connector 40 and a lower pile head 50. The two ends of the fuse tube 20 are connected to the upper pile head 30 and the lower pile head 50 respectively. The two ends of the insulating bottle 10 are connected to the upper pile head 30 and the lower pile head 50 respectively. Please refer to Figure 2-Figure 5 The insulating cover comprises a deformable cover body 1 and an adsorption mechanism 2. The deformable cover body 1 is an insulating member. The insulating cover has good electrical insulation performance, so that it can cover the leakage part to isolate and protect it from the external environment, such as small animals. The cover body 1 has a first half cover 11 and a second half cover 12 relative to each other. The cover body 1 has an enclosed state and an unfolded state. When the cover body 1 is in the unfolded state, the first half cover 11 and the second half cover 12 are separated. The first half cover 11 and the second half cover 12 are opened so that the upper pile head 30 can enter the cover body 1. When the cover body 1 is in the enclosed state, the first half cover 11 and the second half cover 12 enclose an insulating cavity. Specifically, the upper pile head of the fuse is isolated in the insulating cavity. The adsorption mechanism 2 is arranged between the first half cover 11 and the second half cover 12 to switch the cover body 1 between the enclosed state and the unfolded state. Specifically, when the first half cover 11 and the second half cover 12 are opened, the cover body 1 that can be unfolded by the operator is set on the outside of the exposed live part of the drop-out fuse. After the cover body is set on the live part of the leakage, the first half cover 11 and the second half cover 12 are enclosed by the adsorption mechanism 2 to define an insulating cavity. In this way, the live part of the leakage can be enclosed in the insulating cavity. In addition, after the first half cover 11 and the second half cover 12 are enclosed by the adsorption mechanism 2, the cover body can be stably positioned on the drop-out fuse. In this way, the insulating cover can prevent small animals such as squirrels from contacting the exposed power-off part of the drop-out fuse, solving the problem of fuse failure caused by small animals. The insulating cover can be switched between the unfolded state and the enclosed state through the adsorption mechanism. The user can realize non-power-off installation by operating tools. The design is simple and the installation is convenient.

[0044] In some embodiments of the utility model, the first half cover 11 and the second half cover 12 enclose and define a front cavity, a middle cavity and a rear cavity. Here, it should be noted that the "front and back" here refers to the positional relationship between the insulating bottle and the fuse tube, the insulating bottle is in the front direction, and the fuse tube is in the rear direction. The front cavity is suitable for being covered outside the connection between the insulating bottle and the upper pile head; the middle cavity is suitable for being covered outside the connection between the upper pile head; the rear cavity is suitable for being covered outside the connection between the upper pile head and the fuse tube. Specifically, the exposed live parts of the drop-out fuse are mainly the upper pile head, the connection between the upper pile head and the insulating bottle, and the connection between the upper pile head and the fuse tube. The insulating cover at least needs to cover the above exposed live parts. Therefore, the front cavity located in front of the insulating cover can be covered outside the connection between the insulating bottle and the upper pile head, the middle cavity located in the middle of the insulating cover can be covered outside the upper pile head, and the rear cavity located behind the insulating cover can be covered outside the connection between the fuse tube and the upper pile head.

[0045] In some examples, the front cavity, the middle cavity and the rear cavity are connected front to back, and the first half cover 11 and the second half cover 12 are in a sheet-like structure when unfolded, and the cover body 1 can be firmly fixed on the outside of the drop-out fuse after being enclosed.

[0046] It can be understood that in some embodiments, the top of the front cavity forms an upper opening 13, and the upper opening allows the upper connecting wire 40 to pass through. In this way, the insulating cover ensures the connection between the connector and the external upper connecting wire, and the bottom of the front cavity and the rear cavity form openings 14 and 15. It can be understood that the front cavity and rear cavity covers provided in this embodiment are arranged on the top of the insulating bottle and the fuse tube, and the openings 14 and 15 are for the insulating bottle and the fuse tube to pass through.

[0047] In some specific embodiments of the utility model, one end of the top and bottom of the intermediate cavity is closed to form a top cover 16, and the other end has an entrance 17 for the upper pile head to enter. Specifically, in order to prevent small animals from contacting the upper pile head, the top of the intermediate cavity is closed. In addition, in order to ensure that the upper pile head can enter the insulating cover, the intermediate cavity of the insulating cover has an entrance 17 for the upper pile head 30 to enter, thereby ensuring the installation convenience and efficiency of the insulating cover. In a preferred embodiment, the adsorption mechanism includes a first adsorption component 21, and the first adsorption component 21 is arranged at the entrance 17 for closing or opening the entrance 17. In this way, when the upper pile head 30 enters the intermediate cavity corresponding to the insulating cover, the entrance 17 is closed by the first adsorption component. First, the closed insulating cover completely covers the upper pile head in the intermediate cavity; second, it ensures the stability of the insulating cover in the enclosed state to prevent it from shaking or falling. It can be understood that the first adsorption component is positioned between the insulating bottle and the fuse tube.

[0048] In a further preferred embodiment, in order to further ensure that the first half cover 11 and the second half cover 12 can be stably covered outside the fuse after being enclosed, a second adsorption component 22 is provided on the front side of the first half cover 11 and the second half cover 12 to connect the first half cover 11 with the front side of the second half cover 12. Specifically, the first adsorption component and the second adsorption component have the same structure, and the following description will only take the first adsorption component as an example: the first adsorption component includes a left connecting piece 211 and a right connecting piece 212 that are relatively arranged on the left and right, and the left connecting piece and the right connecting piece are respectively provided with a magnetic part 200, 201 on the left and a magnetic part on the right (not shown in the figure) so that the left connecting piece 211 and the right connecting piece 212 can be magnetically attached. Exemplarily, the installation method of the magnetic part is: a groove is formed in the insulating part, and the magnetic part is embedded in the groove.

[0049] Specifically, the insulating cover provided in this embodiment is made of a soft elastic material, for example, rubber. Specifically, the first half cover 11 and the second half cover 12 are often in an enclosed state, and under an external force, the first half cover and the second half cover are separated and opened to allow the leakage part to enter therein, and then the first half cover and the second half cover are automatically enclosed after the external force is removed.

[0050] In some specific examples of the utility model, the first half cover 11 and the second half cover 12 are arranged opposite to each other. Specifically, the top of the first half cover 11 and the second half cover 12 are connected to form a top cover 16, and the front side of the top cover 16 defines an upper opening 13 for external wiring of the connector 40. The bottom of the first half cover 11 and the second half cover 12 is open, wherein the front side of the bottom is open to adapt to the structure of the insulating bottle, and the rear side is open to adapt to the installation of the fuse tube and the heat dissipation of the fuse itself. The middle position of the bottom of the first half cover 11 and the second half cover 12 is closed by the first adsorption component 21, so that the first half cover 11 and the second half cover 12 are firmly fixed to the outside of the drop-out fuse. Furthermore, the opening defined by the front side of the first half cover 11 and the second half cover 12 is opened or closed by the second adsorption component 22. In this embodiment, the rear side of the cover body forms a rear opening 18, so that the design of the rear opening 18 is convenient for heat dissipation of the fuse. Thus, in this embodiment, the bottom and front side of the cover body 1 are closed by the first adsorption component 21 and the second adsorption component 22, so that the cover body 1 can be stably positioned outside the drop-out fuse, while the rear opening 18 and the bottom opening are convenient for installation and heat dissipation.

[0051] By testing the device in areas with high frequency of small animal activities and historical fault locations, no small animal failure incidents have occurred at the use points so far, effectively preventing the occurrence of small animal failures. Example 2

[0052] The present embodiment provides an operating actuator, the operating actuator comprises an operating rod and a clamp, the clamp comprises a left clamp and a right clamp, the left clamp and the right clamp both have magnetic suction parts, so that the first half cover 11 and the second half cover 12 are separated from each other by the magnetic suction effect of the left clamp and the right clamp and the first half cover 11 and the second half cover 12, and the user covers the cover body 1 in an open state on the outside of the drop-out fuse by the clamp, and removes the clamp by relying on the positioning cooperation between the cover body 1 and the insulating bottle and the fuse tube. At this time, the cover body 1 is firmly fixed to the outside of the drop-out fuse by relying on the adsorption mechanism between the first half cover 11 and the second half cover 12.
