Description

Technical Field

[0001] The invention relates to the technical field of lightning arresters, in particular to a lightning arrester with a composite explosion-proof jacket. Background Art

[0002] Installing a lightning arrester can effectively prevent lightning strikes from causing harm to people and ensure human safety. A lightning arrester is an electrical appliance used to protect electrical equipment from high transient overvoltages and limit the follow-on time and often the follow-on amplitude. The lightning arrester is connected between the cable and the ground, usually in parallel with the protected equipment. The lightning arrester can effectively protect communication equipment. Once an abnormal voltage occurs, the lightning arrester will act. When the communication cable or equipment is operating under normal operating voltage, once a high voltage occurs and endangers the insulation of the protected equipment, the lightning arrester will act immediately and direct the high-voltage impact current to the ground, thereby limiting the voltage amplitude and protecting the insulation of the communication cable and equipment. When the overvoltage disappears, the lightning arrester quickly returns to its original state, allowing the communication line to operate normally. However, the fragments of the existing lightning arrester cannot be intercepted when it explodes, increasing the danger.

[0003] The defects of existing lightning arresters are:

[0004] 1. Patent document CN113393989A discloses a lightning arrester, "including: a lightning arrester core, which includes multiple resistors, metal spacers arranged between each adjacent resistor, and epoxy rods; multiple epoxy rods are arranged in the circumference of the lightning arrester core to fix the lightning arrester core; an insulating isolation umbrella, which is ringed on the outer peripheral wall of each metal spacer; wherein multiple lightning arrester cores are connected in parallel, and each lightning arrester core is covered with a jacket. The lightning arrester provided by this application is equipped with an insulating isolation umbrella on the metal spacer. The insulating isolation umbrella has the advantages of high insulation strength, corrosion resistance and flame retardancy. When one of the resistors has an insulation defect and a surface flashover occurs, the insulating isolation umbrella can increase the creepage distance of the arc, prevent the arc from burning the adjacent resistors, and further suppress the arc, thereby avoiding the failure of the entire lightning arrester caused by a single resistor defect." However, the fragments of the existing lightning arrester cannot be intercepted when it explodes, increasing the risk.

[0005] 2. Patent document CN117638529A discloses a lightning arrester, "including a lightning arrester element and a cable connection accessory. The cable connection accessory includes a guide rod, a lightning arrester connector and a cable connector. The lightning arrester connector is electrically connected to the lightning arrester element, and the cable connector is used to electrically connect to the cable. The cable connection accessory and the lightning arrester element are integrally connected by casting, and an external insulation layer is formed outside the cable connection accessory. The external insulation layer has a cable connection hole connected to the cable connector. The cable connection hole is used for connecting the cable to the cable connector to reserve multiple external electrical connection ports. The lightning arrester disclosed in this application adopts an integrated casting and sealing insulation connection between the lightning arrester element and the cable connection accessory, which completely eliminates the hidden dangers of foreign matter intrusion and air residue on the sealed contact surface between the lightning arrester element and the cable connection accessory during installation, and will not form a local discharge hidden danger point, thereby improving the safety of the use of the lightning arrester and ensuring the safe operation of the entire medium-voltage power distribution system." However, the protective cover of the existing lightning arrester cannot be quickly replaced and maintained, which increases manual labor;

[0006] 3. Patent document CN115762924A discloses a lightning arrester, "including a first end fitting, a second end fitting, an insulating tube and an insulating umbrella sleeve, the top of the insulation tube is connected to the first end fitting, the bottom of the insulating tube is connected to the second end fitting, the insulating umbrella sleeve covers the first end fitting, the second end fitting and the radial outer surface of the insulating tube, and the insulating tube is provided with a radial arc groove on the side close to the insulating umbrella sleeve. When in use, the radial outer surfaces of the first end fitting and the second end fitting arranged near the radial arc groove on the side of the insulating tube are squeezed by external force, so that the first end fitting and the second end fitting are radially deformed and tightly connected to the insulating tube, and a radial protrusion is generated on the side of the insulating umbrella sleeve close to the radial arc groove. The insulating umbrella sleeve is integrally injection-molded and hot-pressed to cover the first end fitting, the second end fitting and the radial outer surface of the insulating tube and fit tightly, thereby achieving the purpose of improving the production efficiency of the lightning arrester without reducing the mechanical strength of the lightning arrester." However, the existing lightning arrester cannot automatically reconnect the No. 9 fuse after it breaks, which reduces the stability of the lightning arrester;

[0007] 4. Patent document CN109088386B discloses a box-shaped lightning arrester, "including a mounting plate, the top of the mounting plate is fixedly connected to a mounting box, both sides of the inner wall of the mounting box are fixedly connected to a connecting plate, the top and bottom of one side of the connecting plate are movably connected to a connecting rod through a pin, the other end of the connecting rod is movably connected to an extrusion block through a pin, and a clamping spring is fixedly connected between the opposite sides of the two extrusion blocks, the other side of the extrusion block away from the connecting rod is movably connected to a long rod through a pin, and the other end of the long rod is movably connected to a push plate through a pin, relating to the technical field of box-shaped lightning arresters. The box-shaped lightning arrester can be well installed and disassembled for box-shaped lightning arresters, saving time and effort, and is very convenient to install and disassemble, which is convenient for the maintenance and replacement of the lightning arrester, and does not require multiple staff to operate, saving manpower, thereby greatly improving the practicality of the box-shaped lightning arrester".

[0019] Preferably, the method for using the lightning arrester comprises the following steps:

[0020] Step S1: After the insulating tube bursts, its impact force and fragments rush towards the protective ring, and the fragments are embedded in the protective ring. The impact force drives the protective ring to move, and the movement of the protective ring drives the No. 9 T-bar to move, and the movement of the No. 9 T-bar drives the No. 9 spring to move. The movement of the No. 9 spring reduces the impact force. When the No. 9 T-bar rebounds, it drives the support head to move, and the movement of the support head drives the pulley to move. The movement of the pulley causes the support head to drive the No. 2 spring to move, and the movement of the No. 2 spring further releases the impact force, thereby achieving the function of intercepting fragments when the lightning arrester bursts, reducing the danger and preventing the explosion;

[0021] Step S2: The function of the No. 9 frame is to provide support for the No. 9 slide, pull the pull rod to drive the No. 3 clamp to move, the No. 3 clamp moves to drive the No. 3 spring to move, the No. 3 spring moves to move the No. 3 clamp out of the slot, at this time, pull the protective cover to replace and maintain the protective cover of the lightning arrester, realizing the function of rapid replacement and maintenance of the protective cover of the lightning arrester and reducing manual labor;

This allows the arrester to automatically reconnect the No. 9 fuse after it breaks, improving the arrester's stability.

[0023] Step S4: When the processing module detects a no-resistance state, the processing module controls the wiring assembly to start. After the wiring assembly starts, the No. 2 fuse contacts the connecting plate to automatically connect it. When the processing module detects a resistance state, the processing module controls the wiring assembly not to start. At this time, the lightning arrester is used normally, realizing the function that after the lightning arrester is damaged, the No. 2 fuse promptly connects the lightning arrester to allow it to continue to be used, improving the safety of use.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention is equipped with an insulating cylinder. After the explosion, the impact force and fragments rush towards the protective ring, and the fragments are embedded in the protective ring. The impact force drives the protective ring to move, and the movement of the protective ring drives the No. 9 T-bar to move, and the movement of the No. 9 T-bar drives the No. 9 spring to move. The movement of the No. 9 spring reduces the impact force. When the No. 9 T-bar rebounds, it drives the support head to move, and the movement of the support head drives the pulley to move. The movement of the pulley causes the support head to drive the No. 2 spring to move, and the movement of the No. 2 spring further releases the impact force, thereby achieving the function of intercepting fragments when the lightning arrester explodes, reducing the risk and preventing the explosion.

[0026] 2. The present invention is equipped with a No. 9 frame to provide support for the No. 9 slide. Pulling the pull rod drives the No. 3 clamp to move, and the movement of the No. 3 clamp drives the No. 3 spring to move. The movement of the No. 3 spring causes the No. 3 clamp to move out of the slot. At this time, the protective cover is pulled to replace and maintain the protective cover of the lightning arrester, thereby realizing the function of quickly replacing and maintaining the protective cover of the lightning arrester and reducing manual labor.

[0027] 3. The present invention installs a No. 9 motor to rotate the threaded rod, which in turn drives the threaded sleeve to move, which in turn drives the connecting rod to move, which in turn drives the No. 4 slide cylinder to move, which in turn drives the connecting rod to move the insulating block, which in turn drives the No. 2 fuse to move, which in turn contacts the connecting plate to open it, thereby achieving the function of automatically reconnecting the No. 9 fuse of the arrester after it breaks, improving the stability of the arrester.

[0028] 4. The present invention is equipped with a processing module that detects a no-resistance state, and the processing module controls the wiring assembly to start. After the wiring assembly is started, the No. 2 fuse contacts the connecting plate to automatically connect it to a circuit. When the processing module detects a resistance state, the processing module controls the wiring assembly not to start, and the lightning arrester is used normally at this time. This realizes the function that after the lightning arrester is damaged, the No. 2 fuse promptly connects the lightning arrester to a circuit so that it can continue to be used, improving the safety of use.

The resistance detector 41 is located on the outer wall of the No. 9 fuse 29, the processing module 7 is located on the outer wall of the mounting plate 1, the processing module 7 is electrically connected to the resistance detector 41, the wiring assembly is electrically connected to the processing module 7, the processing module 7 has built-in connection status data of the No. 9 fuse 29, the resistance detector 41 is used to detect the real-time connection status data of the No. 9 fuse 29, the real-time connection status data of the No. 9 fuse 29 is transmitted to the processing module 7, and the real-time connection status data of the No. 9 fuse 29 is compared with the connection status data of the No. 9 fuse 29 by the processing module 7. The real-time connection status data of the No. 9 fuse 29 is different from the connection status data of the No. 9 fuse 29 and is set to a no-resistance state. The real-time connection status data of the No. 9 fuse 29 is set to a resistance state the same as the connection status data of the No. 9 fuse 29. When the processing module 7 detects the no-resistance state, the processing module 7 controls the wiring assembly to start. After the wiring assembly is started, the No. 2 fuse 30 is in contact with the connecting plate 31 to automatically connect it. When the processing module 7 detects the resistance state, the processing module 7 controls the wiring assembly not to start. At this time, the lightning arrester is used normally, thereby realizing the function that after the lightning arrester is damaged, the No. 2 fuse 30 promptly connects the lightning arrester to allow it to continue to be used, thereby improving the safety of use.

[0046] The method of using the lightning arrester includes the following steps:

[0047] Step S1, after the insulating tube 2 bursts, its impact force and fragments rush toward the protective ring 13, and its fragments are embedded in the protective ring 13. The impact force drives the protective ring 13 to move, and the movement of the protective ring 13 drives the No. 9 T rod 12 to move, and the movement of the No. 9 T rod 12 drives the No. 9 spring 10 to move, and the movement of the No. 9 spring 10 reduces the impact force. When the No. 9 T rod 12 rebounds, it drives the support head 17 to move, and the movement of the support head 17 drives the pulley 16 to move. The movement of the pulley 16 causes the support head 17 to drive the No. 2 spring 18 to move, and the movement of the No. 2 spring 18 further releases the impact force, thereby achieving the function of intercepting fragments when the lightning arrester bursts, reducing the danger and preventing the explosion;

[0048] Step S2, the role of the No. 9 frame 24 is to provide support for the No. 9 slide 28, pull the pull rod 23 to drive the No. 3 clamp 27 to move, the No. 3 clamp 27 moves to drive the No. 3 spring 26 to move, the No. 3 spring 26 moves to move the No. 3 clamp 27 out of the slot 22, at this time, pull the protective cover 6 to replace and maintain the protective cover 6 of the lightning arrester, realizing the function of quickly replacing and maintaining the protective cover 6 of the lightning arrester and reducing manual labor;

[0049] Step S3: The No. 9 motor 33 rotates to drive the threaded rod 34 to rotate, the rotation of the threaded rod 34 drives the threaded sleeve 35 to move, the movement of the threaded sleeve 35 drives the connecting rod 38 to move, the movement of the connecting rod 38 drives the No. 4 slide 37 to move, the movement of the No. 4 slide 37 causes the connecting rod 38 to drive the insulating block 40 to move, the movement of the insulating block 40 drives the No. 2 fuse 30 to move, the No. 2 fuse 30 moves to contact the connecting plate 31 to make it pass, thereby realizing the function of automatically reconnecting the No. 9 fuse 29 of the lightning arrester after it breaks, improving the stability of the lightning arrester;

[0050] In step S4, when the processing module 7 detects a no-resistance state, the processing module 7 controls the wiring assembly to start. After the wiring assembly is started, the No. 2 fuse 30 contacts the connecting plate 31 to automatically connect it to a circuit. When the processing module 7 detects a resistance state, the processing module 7 controls the wiring assembly not to start. At this time, the lightning arrester is used normally, realizing the function that after the lightning arrester is damaged, the No. 2 fuse 30 promptly connects the lightning arrester to a circuit so that it can continue to be used, improving the safety of use.

[0051] Working principle: after the insulating tube 2 bursts, its impact force and fragments rush towards the protective ring 13, and its fragments are embedded in the protective ring 13. The impact force drives the protective ring 13 to move, and the movement of the protective ring 13 drives the No. 9 T rod 12 to move, and the movement of the No. 9 T rod 12 drives the No. 9 spring 10 to move. The movement of the No. 9 spring 10 reduces the impact force, and when the No. 9 T rod 12 rebounds, it drives the support head 17 to move, and the movement of the support head 17 drives the pulley 16 to move, and the movement of the pulley 16 causes the support head 17 to drive the No. 2 spring 18 to move The movement of the No. 2 spring 18 further releases the impact force, thereby intercepting the fragments when the arrester bursts, reducing the danger and preventing the explosion. The function of the No. 9 frame 24 is to provide support for the No. 9 slide 28, pulling the pull rod 23 drives the No. 3 clamp 27 to move, and the No. 3 clamp 27 moves to drive the No. 3 spring 26 to move. The No. 3 spring 26 moves to move the No. 3 clamp 27 out of the card slot 22. At this time, the protective cover 6 of the arrester is pulled to replace and maintain the protective cover 6 of the arrester, thereby realizing the protection of the arrester. The function of quick replacement and maintenance reduces manual labor. The rotation of the ninth motor 33 drives the threaded rod 34 to rotate. The rotation of the threaded rod 34 drives the threaded sleeve 35 to move. The movement of the threaded sleeve 35 drives the connecting rod 38 to move. The movement of the connecting rod 38 drives the fourth slide 37 to move. The movement of the fourth slide 37 causes the connecting rod 38 to drive the insulating block 40 to move. The movement of the insulating block 40 drives the No. 2 fuse 30 to move. The No. 2 fuse 30 moves and contacts the connecting plate 31 to make it pass through, realizing the function of automatically repairing the No. 9 fuse 29 of the lightning arrester after it is broken to improve the stability of the lightning arrester. When the processing module 7 detects the no-resistance state, the processing module 7 controls the wiring assembly to start. After the wiring assembly is started, the No. 2 fuse 30 contacts the connecting plate 31 to make it automatically pass through. When the processing module 7 detects the resistance state, the processing module 7 controls the wiring assembly not to start. At this time, the lightning arrester is used normally, realizing the function of the No. 2 fuse 30 promptly passing through the lightning arrester after the lightning arrester is damaged so that it can continue to be used and improve the safety of use.
