[0002] In the power system, various electrical equipment will be damaged by the impact of lightning overvoltage. At this time, it is necessary to install a lightning arrester to protect the circuit. The lightning arrester is connected between the cable and the earth, usually in parallel with the protected equipment. Once an abnormal voltage appears, the lightning arrester will be activated to guide the high voltage impact current to the earth, thereby limiting the voltage amplitude, protecting the communication cables and equipment, and playing a protective role.

[0003] When protecting the equipment in the power system, it is necessary to install a lightning arrester, through which the high voltage impact current can be directed to the earth. When the existing lightning arrester is used, the threaded rod at the bottom passes through the mounting bracket, and then the nut and bolt are turned for threaded transmission to fix the lightning arrester to the bracket. However, this installation method has only the supporting point of the lightning arrester where the threaded rod contacts the bracket. When encountering strong wind weather, the lightning arrester has a weak wind resistance due to the single supporting point. Utility Model Content

[0014] 1. When protecting equipment in the power system, it is necessary to install a lightning arrester. The lightning arrester can guide high-voltage impulse current to the earth. When installing the lightning arrester, the threaded rod at the bottom of the lightning arrester body is passed through the through hole in the bracket. When the first sliding block at the bottom of the base plate contacts the bracket, the first sliding block will slide in the slide groove in the threaded rod and push the connecting rod to rotate and unfold. When the connecting rod rotates, it will push the reinforcement plate out of the inside of the base plate, thereby increasing the support area at the bottom of the base plate. When the base plate and the reinforcement plate contact the bracket, the reinforcement plate will be fully unfolded. At this time, the nut and the threaded rod can be rotated for threaded transmission to limit the first sliding block, thereby fixing the position of the reinforcement plate. The unfolded reinforcement plate can reinforce and support the lightning arrester body. In this way, the above operation can facilitate the reinforcement and support of the lightning arrester and improve the installation strength of the lightning arrester.

[0015] 2. When protecting the equipment in the power system, it is necessary to install a lightning arrester. The lightning arrester can guide the high voltage impact current to the earth. When connecting the cable on the top of the lightning arrester, the cable is inserted into the wiring hole inside the power connection block. When the cable contacts the ball, the ball will move up and then push the limit plate to move. When the limit plate moves, it will push the ball to move down. When the ball moves down, it will push the cable to deform and enter the limit groove, and continue to push the limit plate. When the groove inside the limit plate contacts the ball, the ball will engage with the limit plate, and under the push of the cable reset force, the ball will be squeezed with the limit plate to complete the limit on the limit plate. In this way, the cable can be easily installed in the lightning arrester through the above operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 4The utility model provides a technical solution: a lightning arrester with a reinforcement structure, comprising: a lightning arrester body 1 and a reinforcement plate 9, a conductive frame 2 is fixedly connected to the top of the lightning arrester body 1, and a power connection block 3 is fixedly connected to the top of the conductive frame 2.

[0025] The bottom of the arrester body 1 is fixedly connected to a base plate 4, the bottom of the base plate 4 is fixedly connected to a threaded rod 5, the outer side of the threaded rod 5 is threadedly connected to a nut 6, a sliding groove for the first sliding block 7 to slide is provided inside the nut 6, one side of the first sliding block 7 is movably connected to a connecting rod 8 through a rotating shaft, and one side of the connecting rod 8 is movably connected to a reinforcing plate 9 through a rotating shaft; one side of the reinforcing plate 9 is fixedly connected to a tension spring 10, one end of the tension spring 10 is fixedly connected to the base plate 4; a second sliding block 11 is welded and fixed to the top of the reinforcing plate 9, and a sliding groove for the second sliding block 11 to slide is provided inside the base plate 4; the bottom of the threaded rod 5 is fixedly connected to a wiring terminal 12, three groups of reinforcement plates 9 are provided, and are distributed at equal angles with respect to the central axis of the threaded rod 5, the connecting rod 8 forms a rotating structure with the reinforcement plate 9 through the rotating shaft, and the threaded rod 5 and the nut 6 form a threaded transmission structure.

[0026] In specific implementation, when protecting the equipment in the power system, it is necessary to install a lightning arrester, through which the high voltage impact current can be directed to the earth. When installing the lightning arrester, the threaded rod 5 at the bottom of the lightning arrester body 1 is passed through the through hole in the bracket. When the first sliding block 7 at the bottom of the bottom plate 4 contacts the bracket, the first sliding block 7 will slide in the slide groove in the threaded rod 5 and push the connecting rod 8 to rotate and unfold. When the connecting rod 8 rotates, it will push the reinforcement plate 9 out of the inside of the bottom plate 4. When the reinforcement plate 9 moves, it will pull the tension spring 10 to stretch. Since there are three groups of connecting rods 8 and reinforcement plates 9, the three The group of reinforcement plates 9 can be moved at the same time to increase the supporting area at the bottom of the base plate 4. When the base plate 4 and the reinforcement plate 9 contact the bracket, the reinforcement plate 9 will be fully unfolded. At this time, the nut 6 and the threaded rod 5 can be rotated for threaded transmission to limit the first sliding block 7, so that the position of the reinforcement plate 9 is also fixed. The unfolded reinforcement plate 9 can reinforce and support the lightning arrester body 1. When the lightning arrester is transported, the reinforcement plate 9 will be inside the base plate 4 under the action of the tension of the tension spring 10, reducing the volume occupied by the lightning arrester. In this way, the above operation can facilitate the reinforcement and support of the lightning arrester and improve the installation strength of the lightning arrester.

[0027] See also Figure 1 , Figure 3 , Figure 5 and Figure 6A wiring hole 13 is provided inside the power connection block 3, and a movable groove for sliding a limit plate 14 is provided inside the power connection block 3; a ball 15 is provided on one side of the limit plate 14, and a movable groove for moving the ball 15 is provided inside the power connection block 3; a limit groove 16 is provided on the side of the power connection block 3 close to the ball 15, and a groove 17 matching the ball 15 is provided inside the limit plate 14, and the limit plate 14 forms a sliding structure with the power connection block 3 through a slider.

[0028] In specific implementation, when protecting the equipment in the power system, it is necessary to install a lightning arrester, through which the high voltage impact current can be directed to the earth. When connecting the cable on the top of the lightning arrester, the cable is inserted into the wiring hole 13 inside the power connection block 3. When the cable contacts the ball 15, the ball 15 will move up and then push the limit plate 14 to move. When the limit plate 14 moves, it will push the ball 15 to move down. When the ball 15 moves down, it will push the cable to deform and enter the limit groove 16, and continue to push the limit plate 14. When the groove 17 inside the limit plate 14 contacts the ball 1 5, the ball 15 will be engaged with the limit plate 14, and under the push of the cable reset force, the ball 15 will be squeezed tightly with the limit plate 14 to complete the limitation of the limit plate 14. When the cable is pulled by an external force, due to the limitation of the limit groove 16, the cable will squeeze the ball 15 to move upward, and the ball 15 will not move due to the limitation of the limit plate 14, so the cable will not move. When the cable needs to be taken out, the limit plate 14 is pulled out of the limitation of the ball 15. At this time, the ball 15 can move, and the cable can be pulled out of the power connection block 3. In this way, the cable can be easily installed in the lightning arrester through the above operation.
