Description

Technical Field

[0001] The present invention relates to the technical field of lightning arresters, and in particular to a plug-in lightning arrester. Background Art

[0002] Lightning arrester is a device that protects the protected equipment of the substation from lightning shock waves. When the lightning shock wave transmitted to the substation along the line exceeds the protection level of the lightning arrester, the lightning arrester first discharges and safely introduces the lightning current into the earth through a good conductor. The grounding device is used to limit the amplitude of the lightning voltage to below the lightning shock level of the protected equipment, so that the electrical equipment is protected.

[0003] Lightning arresters can be divided into the following categories according to their development order: the protective gap is the simplest form of lightning arrester; the tube-type lightning arrester is also a protective gap, but it can extinguish the arc by itself after discharge; the valve-type lightning arrester divides a single discharge gap into many short series gaps, while increasing nonlinear resistance to improve protection performance. Usually, the lightning arrester is installed on the bracket of a utility pole for use.

[0004] For example, a Chinese patent (CN218733158U) discloses an insulating mounting bracket for a lightning arrester with a disconnector, comprising a lightning arrester body, a high-voltage connector and a disconnector body, wherein the high-voltage connector is arranged on the top of the lightning arrester body, the disconnector body is threadedly connected to the bottom of the lightning arrester body, a fixing ring is provided at the bottom of the lightning arrester body, and a mounting frame is provided on one side of the bottom of the lightning arrester body.

[0005] The above patent uses fixing bolts to fix the mounting frame and the arrester body after splicing the splicing hoop and the arc-shaped fixing hoop; since the arrester is fixed and installed by bolts, the bolts are exposed to the outside world for a long time and rusted by rain erosion, which makes it inconvenient to disassemble the arrester; when the arrester is fixed to the mounting frame with bolts, auxiliary tools are required to operate, which is troublesome to operate at high altitude, and the bolts may slip, affecting the tightness of the connection.

[0006] Therefore, the present invention provides a plug-in lightning arrester to solve the above problems. Summary of the invention

[0036] Refer to the following Figures 1 to 12 The embodiments of the present invention are described in detail. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0037] A plug-in lightning arrester, such as Figure 1 , Figure 2 , Figure 4 , Figure 6 , Fig. 9 , Fig.10 , Fig.12 As shown, it includes a mounting base 1, a socket 2 is fixedly mounted on the rear end of the mounting base 1, a circular socket hole 3 which passes through from top to bottom is provided in the middle of the socket 2, a lightning arrester 4 is provided above the socket 2, a circular filling body 5 is fixedly mounted on the lower end of the lightning arrester 4, the filling body 5 can be appropriately inserted into the inside of the socket hole 3, a plurality of sockets 6 are evenly arranged on the outer end of the filling body 5, three sockets 6 are arranged here, three slide grooves 7 which pass through the socket hole 3 are provided on the socket 2, a sliding block 8 is slidably mounted inside each of the slide grooves 7, one end of the sliding block 8 is a round head, which is convenient for insertion into the inside of the socket 6, a stopper 9 is fixedly mounted on the top of each of the sliding blocks 8, a pressure spring 10 is fixedly mounted on one end of each of the stoppers 9, and the other end of the pressure spring 10 is fixedly mounted on the inner wall of the slide groove 7;

[0038] An inclined surface 11 is provided on the inner end of each sliding plug block 8, and the inclined surface 11 is inclined downward. Three plug rod holes 12 are provided on the plug seat 2, and the plug rod holes 12 are connected with the corresponding slide grooves 7 up and down. A plug rod 13 is installed in the interior of each plug rod hole 12 for sliding up and down movement, and the top of the plug rod 13 is a spherical head. A threaded ring 14 is fixedly installed on the bottom end of the plug seat 2, and the threaded ring 14 is connected with the plug hole 3 up and down. A driving ring 15 is threadedly installed on the outer end of the threaded ring 14. The bottom end surface of each plug rod 13 is slidably connected with the top end surface of the driving ring 15, and a resistance block 16 extending into the plug hole 3 is fixedly installed on the inner wall of the driving ring 15, and the top surface of the resistance block 16 contacts with the bottom surface of the plug seat 2;

[0039] When in use, the personnel holds the lower end of the lightning arrester 4 close to the plug hole 3, and the filling body 5 is quickly inserted into the plug hole 3. When the bottom surface of the filling body 5 contacts the top surface of the abutment block 16, the filling body 5 stops moving due to the obstruction of the abutment block 16. At this time, each plug hole 6 corresponds to the corresponding slide groove 7, and the driving ring 15 is rotated and moves upward along the threaded ring 14. The bottom surface of each plug rod 13 slides along the top of the driving ring 15, and the plug rod 13 slides upward along the plug rod hole 12. The spherical head on the plug rod 13 slides along the inclined surface 11, and the round heads of the three sliding plug blocks 8 are gradually inserted into the corresponding plug holes 6. At the same time, the stopper 9 presses the pressure spring 10 in a compressed state, thereby blocking the filling body 5 and preventing the lightning arrester 4 from shaking during use. Due to the perfect fit between the filling body 5 and the plug hole 3, and the sliding plug block 8 is inserted into the inside of the plug hole 6, the lightning arrester 4 can be quickly plugged in and installed and removed, and the stability of the lightning arrester 4 during use is also improved;

[0040] Without the need for auxiliary tools, it can be quickly installed at high altitude or low altitude, which makes the operation more convenient and prevents the arrester 4 from falling off, thus reducing human errors, lowering maintenance costs, and ensuring the safety and reliability of the equipment.

[0041] like Figure 5 , Figure 8 , Fig. 9 As shown, the socket 2 is provided with three built-in holes 31 vertically connected with the plug hole 3, each built-in hole 31 is arranged between two slide grooves 7, a driving device is arranged inside each built-in hole 31, an interception ring 17 is installed between the tops of the three driving devices, a stabilizing ring 18 located above the filling body 5 is fixedly installed on the lower end of the arrester 4, the outer diameter of the stabilizing ring 18 is smaller than the inner diameter of the plug hole 3, three fixing bodies 19 are evenly fixedly installed on the outer end of the stabilizing ring 18, a guide groove 20 is provided at the upper end of each fixing body 19, an interception block 21 is slidably installed inside each guide groove 20, each interception block 21 is provided with a rectangular hole 22, a rectangular block 23 located inside the rectangular hole 22 is fixedly installed inside each guide groove 20, and the rectangular block 23 can slide freely inside the corresponding rectangular hole 22, and a lifting device located above the fixed body 19 is provided on the arrester 4;

[0042] When in use, the lifting device is manually driven to move upward, and the three interception blocks 21 are moved toward the arrester 4 along the guide groove 20 until the three interception blocks 21 are hidden in the corresponding guide groove 20, and then the filling body 5 is slid downward along the plug-in hole 3, and the driving device moves the interception ring 17 upward. When the bottom surface of the filling body 5 contacts the top surface of the abutment block 16, the lifting device is released, and the three rectangular blocks 23 at this time slide along the guide groove 20 away from the arrester 4, and the three interception blocks 21 quickly slide to the bottom of the interception ring 17, thereby blocking the interception ring 17, so as to realize the installation of the arrester 4. Due to the blocking of the interception ring 17 by the interception block 21, the arrester 4 will not fall off from the socket 2, which improves stability and is more convenient to install. Since the plug-in arrester simplifies the installation and disassembly process, the workload of maintenance and servicing is reduced, thereby reducing the maintenance cost.

[0043] Then the personnel rotates the drive ring 15 and moves upward along the threaded ring 14. The bottom surface of each plug rod 13 will slide on the top of the drive ring 15, and the plug rod 13 will slide upward along the plug rod hole 12. The spherical head of the plug rod 13 slides along the inclined surface 11 until the round heads of the three sliding blocks 8 are completely inserted into the corresponding sockets 6. At the same time, the block 9 presses the pressure spring 10 in a compressed state, thereby blocking the filling body 5 again, further improving the stability of the lightning arrester 4. When the lightning arrester 4 needs to be disassembled, the corresponding components can be restored to their initial state.

[0044] like Figure 5 , Figure 8 As shown, the lifting device includes a lifting ring 24, an extension ring 25 is fixedly installed on the top of the stabilizing ring 18, and the extension ring 25 is fixedly installed on the arrester 4. The arrester 4 is sleeved with a lifting ring 24 located above the extension ring 25, and the lifting ring 24 is slidably installed on the arrester 4 up and down, and three fixed shells 26 are evenly fixedly installed on the outer end of the lifting ring 24, and a mounting opening 27 is opened on the top of each intercepting block 21, and a push connecting rod 28 is rotatably installed inside each mounting opening 27, and the other end of each push connecting rod 28 is rotatably installed on the corresponding fixed shell 26;

[0045] When in use, the lifting ring 24 is driven to slide upward along the lightning arrester 4, the three fixed shells 26 move with the corresponding pushing connecting rods 28, and the three intercepting blocks 21 slide along the guide groove 20 away from the lightning arrester 4. When the intercepting ring 17 moves upward to a suitable height, the lifting ring 24 is released, and the three intercepting blocks 21 quickly slide to the bottom of the intercepting ring 17, thereby blocking the intercepting ring 17. Since the intercepting blocks 21 can block the intercepting ring 17, the lightning arrester 4 will not fall off the socket 2, thereby improving stability.

[0046] like Figure 8 , Fig. 9As shown, the driving device includes a first rack 29 and a second rack 30, the built-in hole 31 is connected with the plug-in hole 3, the inner wall of each built-in hole 31 is slidably mounted with a first rack 29, the tops of the three first racks 29 are fixedly mounted on the interception ring 17, and the inner end of each built-in hole 31 is rotatably mounted with a driving gear 32 meshing with the first rack 29, an isolation ring 33 is fixedly mounted between the top of the filling body 5 and the bottom end of the stabilizing ring 18, the isolation ring 33 is sleeved on the outer end of the arrester 4, and three second racks 30 extending downward are evenly fixedly mounted on the outer end of the isolation ring 33;

[0047] When in use, each second rack 30 is inserted into the corresponding built-in hole 31, and the filling body 5 is inserted into the inside of the plug-in hole 3. At this time, the three second racks 30 are meshed and rotated with the corresponding driving gears 32, and the three driving gears 32 are meshed with the first racks 29 to slide upward along the built-in holes 31. At this time, the three first racks 29 jointly push the interception ring 17 to move upward, and the interception ring 17 gradually moves away from the top surface of the plug-in socket 2. When the bottom surface of the filling body 5 contacts the top surface of the resistance block 16, the lifting device is released, and the three interception blocks 21 are moved along the guide Slide toward the groove 20 and away from the lightning arrester 4, and the three interception blocks 21 quickly slide to the bottom of the interception ring 17. At this time, the top surface of the interception block 21 contacts the bottom surface of the interception ring 17, forming a blocking effect on the interception ring 17, and the interception ring 17 no longer moves downward, thereby realizing the installation of the lightning arrester 4. Since the interception block 21 can block the interception ring 17, the stability of the lightning arrester 4 is improved, and the installation and disassembly are also more convenient, which saves labor, reduces the installation difficulty and operation time, and improves the overall operation reliability of the power grid.

[0048] like Figure 8 , Fig. 9 As shown, three pressure blocks 34 are evenly fixedly installed on the outer end of the isolation ring 33, and a pressure block 34 is provided between each two second racks 30. The socket 2 is provided with three pressure block holes 35 with openings facing upwards, and the pressure block holes 35 are arranged just above the corresponding slide grooves 7. A top pressure spring 36 is fixedly installed inside each of the pressure block holes 35;

[0049] When the filling body 5 slides downward along the plug hole 3, the pressure block 34 at this time slides in the corresponding pressure block hole 35 and presses the top pressure spring 36 to be gradually compressed. When the three interception blocks 21 quickly slide to the bottom of the interception ring 17, due to the rebound force of the top pressure spring 36, the pressure block 34 always pushes the interception ring 17 tightly, preventing the filling body 5 from sliding up and down and shaking inside the plug hole 3 during use, thereby improving the stability of the lightning arrester 4.

[0050] like Figure 5 , Figure 8As shown, a lifting plate 37 is fixedly installed on the top of the lifting ring 24, and the lifting plate 37 is slidably sleeved on the arrester 4 up and down. A downward pressure spring 38 is fixedly installed on the top of the lifting plate 37, and the downward pressure spring 38 is sleeved on the arrester 4, and the top of the downward pressure spring 38 is fixedly connected to the arrester 4. The outer end of the lifting plate 37 is provided with a first friction pattern 39;

[0051] When in use, the lifting plate 37 is manually held and moved upward. The first friction pattern 39 can increase the friction with the hand, and the downward pressure spring 38 is continuously compressed to drive the lifting ring 24 to slide upward along the lightning arrester 4. The three fixed shells 26 move with the corresponding pushing connecting rods 28, and the three intercepting blocks 21 gradually slide close to the lightning arrester 4 along the guide groove 20. When the bottom surface of the filling body 5 contacts the top surface of the resistance block 16, the intercepting ring 17 moves upward to a certain height at the same time, and the lifting plate 37 is released. Due to the reset force of the downward pressure spring 38, the three intercepting blocks 21 quickly slide to the bottom of the intercepting ring 17 to block it and prevent the intercepting ring 17 from moving downward, thereby realizing the rapid installation of the lightning arrester 4 and improving the installation efficiency.

[0052] like Figure 1 , Figure 2 As shown, a front protective shell 40 and a rear protective shell 41 are provided on the outside of the socket 2, the front ends of the front protective shell 40 and the rear protective shell 41 are connected by a hinge 42, the rear ends of the front protective shell 40 and the rear protective shell 41 are connected by a lock 43, and the top ends of the front protective shell 40 and the rear protective shell 41 are respectively fixedly connected with a compression shell 46, and the compression shell 46 has a compression elastic property;

[0053] During use, after the installation of the lightning arrester 4 is completed, the personnel take the front protective shell 40 and the rear protective shell 41 and wrap them on the outer end of the socket 2, and wrap the two compression shells 46 on the outside of the lifting plate 37, and then use the lock 43 to install the front protective shell 40 and the rear protective shell 41. At this time, the front protective shell 40, the rear protective shell 41, and the two compression shells 46 completely wrap and protect the inner parts to prevent damage by rain, which also increases the service life of the lightning arrester 4 and facilitates later disassembly.

[0054] like Figure 7 As shown, sealing blocks 44 are fixedly installed at the upper and lower ends of each built-in hole 31. The setting of the sealing block 44 can isolate the first rack 29 and the second rack 30 on the same side, thereby improving the stability of the first rack 29 and the second rack 30 during the sliding process.

[0055] like Figure 1 As shown, the front end bolts of the mounting base 1 are installed with a mounting frame 45, and the mounting frame 45 is installed on a telephone pole or other suitable positions through corresponding components.

[0056] Working principle of the present invention:

[0057] Installation of lightning arrester:

[0058] Manually hold the lifting plate 37 and move it upward, the pressing spring 38 is continuously compressed, driving the lifting ring 24 to slide upward along the arrester 4, and the three fixed shells 26 slide with the interception block 21 through the corresponding push rods 28. The interception block 21 gradually approaches the arrester 4 while sliding along the guide groove 20, and the filling body 5 is inserted into the inside of the plug hole 3;

[0059] Then the three second racks 30 mesh with the corresponding driving gears 32 and rotate, and the three driving gears 32 mesh with the first racks 29 and slide upward along the built-in holes 31. At this time, the three first racks 29 jointly push the interception ring 17 to move upward, and the interception ring 17 gradually moves away from the top surface of the socket 2. When the bottom surface of the filling body 5 contacts the top surface of the abutment block 16, the lifting plate 37 is released. Due to the rebound force of the downward pressure spring 38, the three interception blocks 21 quickly slide to the bottom of the interception ring 17 to block the interception ring 17, thereby improving the stability of the lightning arrester 4 and making it more convenient to install, saving labor, reducing the difficulty of installation and operation time, and improving the overall operation reliability of the power grid;

[0060] Then, the driving ring 15 is rotated and moves upward along the threaded ring 14, and the bottom surface of each plug rod 13 slides along the top of the driving ring 15, and the plug rod 13 slides upward along the plug rod hole 12, and the spherical head on the plug rod 13 slides along the inclined surface 11 until the round heads of the three sliding plug blocks 8 are completely inserted into the corresponding plug holes 6, and at the same time, the stopper 9 presses the pressure spring 10 in a compressed state, thereby blocking the filling body 5 to prevent the lightning arrester 4 from shaking during use. Due to the cooperation between the filling body 5 and the plug hole 3, and the sliding plug block 8 is inserted into the inside of the plug hole 6, the lightning arrester 4 can be quickly plugged in and removed, and the stability of the lightning arrester 4 during use is improved. Without the need for auxiliary tools, it can be quickly installed at high altitude or low altitude, and the operation is more convenient. There is no situation that the lightning arrester 4 falls off, which reduces human errors, reduces maintenance costs, and ensures the safety and reliability of the equipment.

[0061] Disassembly of lightning arrester:

[0062] The driving ring 15 is rotated in the opposite direction and moves downward along the threaded ring 14. The rebound force of the pressure spring 10 pushes the stopper 9 to move outward, and the sliding block 8 pushes the insertion rod 13 to slide downward until the sliding block 8 is completely removed from the insertion hole 6. At this time, the driving ring 15, the pressure spring 10, the stopper 9, the sliding block 8, and the insertion rod 13 return to the initial state, realizing the limit release state of the filling body 5;

[0063] The lifting plate 37 is then manually held and moved upward, the downward pressure spring 38 is continuously compressed, and the lifting ring 24 is driven to slide upward along the lightning arrester 4. The three fixed shells 26 slide with the intercepting block 21 through the corresponding pushing connecting rods 28. When the top surface of the intercepting block 21 is no longer in contact with the bottom surface of the intercepting ring 17, due to the rebound force of the top pressure spring 36, the pressing block 34 slides quickly with the filling body 5 from the plug-in hole 3, and the filling body 5 is limited again. Then the personnel continue to move upward with the filling body 5, and the second rack 30 engages and rotates in the opposite direction with the corresponding driving gear 32. The driving gear 32 engages with the first rack 29 and slides downward along the built-in hole 31. The three first racks 29 move downward with the intercepting ring 17 together. When the filling body 5 is completely disengaged from the plug-in hole 3, the first rack 29 and the intercepting ring 17 return to their initial state, and the lifting plate 37 can be released. Since the plug-in lightning arrester simplifies the installation and disassembly process, the workload of maintenance and servicing is reduced, thereby reducing the maintenance cost.
