Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lightning arresters, and more particularly, to a high anti-seismic high-voltage lightning arrester. BACKGROUND

[0002] A lightning arrester is an electrical device used to protect electrical equipment from lightning-induced high transient overvoltages and to limit the time of current flow, and often to limit the current flow amplitude. Lightning arresters are sometimes also called overvoltage protectors or overvoltage limiters.

[0003] The patent with the application number CN202211314098.9 discloses a lightning arrester with shock absorption function, relating to the technical field of lightning arresters, comprising a mounting box, two top rods are slidably connected to the upper surface of the mounting box, an installation plate is fixedly connected to the upper ends of the two top rods, a lightning attractor is fixedly connected to the upper surface of the installation plate, a moving plate is fixedly connected to the lower ends of the two top rods, four springs are fixedly connected to the upper surface of the moving plate, the ends of the springs away from the moving plate are fixedly connected to the top inner wall of the mounting box, the moving plate is slidably connected to the inner wall of the mounting box, and a shock absorption structure is arranged on the lower surface of the moving plate. The application achieves the effect of offsetting the vibration of the lightning attractor by the damping sheet when the lightning attractor vibrates, so that the lightning attractor will not vibrate again due to the elastic force of the spring when it is reset, avoiding secondary damage to the lightning attractor and prolonging the service life of the lightning attractor.

[0004] Although the shock absorption structure of the above-mentioned application can avoid secondary damage to the lightning attractor during resetting, the lightning arrester will be subjected to different amplitudes of vibration due to different factors during use. If severe and large amplitude vibration occurs, the shock absorption structure cannot adjust the buffer rigidity according to the vibration amplitude, and when the buffer limit is reached, impact will still occur, causing damage to the lightning arrester. At the same time, when the lightning arrester continuously receives high voltage (such as frequent lightning strikes within a short period of time), it cannot completely release the energy, and the generated energy will gradually accumulate, which will cause the lightning arrester to overheat, and in severe cases, the internal components may be burned or the shell may explode, causing the lightning arrester to fail.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] The arrester will be subjected to different amplitudes of vibration due to different factors in the use process. If severe large amplitude vibration occurs, the damping structure cannot adjust the buffer rigidity according to the vibration amplitude, and when the buffer limit is reached, impact will still occur, causing damage to the arrester.

[0030] Embodiment one With reference to Figures 1 to 9 The high anti-seismic high-voltage lightning arrester comprises a lightning arrester body 1, and further comprises a buffer assembly 2.

[0031] With reference to Figures 2 to 8 The buffer assembly 2 comprises a mounting seat 21, and a first chamber 22 and a second chamber 23 are sequentially arranged in the mounting seat 21 from inside to outside. The top of the first chamber 22 is provided with a gas outlet channel 24 and a plurality of throttling channels 25, which are in communication with the outside. A first piston piece 26 is slidably connected in the first chamber 22. The top of the first piston piece 26 is fixedly connected with a support rod 27. The diameter of the support rod 27 is smaller than that of the gas outlet channel 24. The lightning arrester body 1 is fixedly connected to the top of the support rod 27. A plurality of limiting blocks 28 for limiting the sliding of the support rod 27 are fixedly connected to the upper portion of the gas outlet channel 24. The top of the first piston piece 26 is fixedly connected with a blocking piece 29, which is sleeved on the outer wall of the support rod 27. The blocking piece 29 is arranged in a stepped structure with gradually increasing diameter from top to bottom.

[0032] With reference to Figure 3 And Figure 4 The second piston piece 210 is slidably connected in the second chamber 23. The bottom of the second piston piece 210 is fixedly connected with a support piece 211. A plurality of communication holes 212 are arranged in the lower portion of the first chamber 22 and are in communication with the second chamber 23. When the second piston piece 210 is located at the bottom of the second chamber 23, the support piece 211 is higher than the plurality of communication holes 212 under the support of the support piece 211. The interiors of the first chamber 22 and the second chamber 23 are filled with hydraulic oil between the first piston piece 26 and the second piston piece 210. The bottom of the first piston piece 26 is fixedly connected with a plurality of blocking plates 213. The number of the blocking plates 213 is less than that of the communication holes 212. Each blocking plate 213 corresponds to one communication hole 212 and can block the corresponding communication hole 212 when moving to the bottom limit position.

[0033] With reference to Figure 3 , Figure 4 And Figure 8The interior of the mounting seat 21 is provided with a third chamber 214 above the second chamber 23, the interior of the third chamber 214 is slidably connected with a third piston piece 215, the side of the third piston piece 215 away from the second chamber 23 is connected with a first elastic piece 216 between the third chamber 214, the first elastic piece 216 is used for resetting the third piston piece 215, a plurality of air passing holes 217 are arranged between the third chamber 214 and the second chamber 23, the interior of the mounting seat 21 is provided with a plurality of expansion grooves 218 which are same in number and corresponding in position with the air passing holes 217, each expansion groove 218 penetrates the corresponding air passing hole 217, the interior of the mounting seat 21 is provided with adjusting grooves 219 which are same in number and corresponding in position with the expansion grooves 218 between the first chamber 22 and the second chamber 23, each adjusting groove 219 is in communication with the corresponding expansion groove 218, the interior of each expansion groove 218 is slidably connected with a blocking block 220 used for blocking the corresponding air passing hole 217, the interior of each adjusting groove 219 is slidably connected with an adjusting plate 221 fixedly connected with the corresponding blocking block 220, the outer circumferential side of the first piston piece 26 is fixedly embedded with first magnetic pieces 222 which are same in number and corresponding in position with the expansion grooves 218, the side of each adjusting plate 221 close to the first chamber 22 is fixedly embedded with a second magnetic piece 223 and a third magnetic piece 224, a plurality of air release holes 225 are arranged in the third chamber 214 and in communication with the outside, for the gas in the third chamber 214 to flow when the third piston piece 215 moves.

[0034] When the first piston piece 26 is located at the top position of the first chamber 22, the first magnetic piece 222 is corresponding in position with the second magnetic piece 223, the first magnetic piece 222 can push the adjusting plate 221 and drive the blocking block 220 to block the air passing hole 217 through repulsion of the same polarity of the magnetic poles of the second magnetic piece 223; When the second piston piece 210 compresses the gas in the second chamber 23 to move to the limit position, the first piston piece 26 drives the first magnetic piece 222 to move to the lower part of the first chamber 22, the first magnetic piece 222 is corresponding in position with the third magnetic piece 224, the first magnetic piece 222 can drive the adjusting plate 221 and the blocking block 220 to unblock the air passing hole 217 through attraction of the different polarity of the magnetic poles of the third magnetic piece 224.

[0035] In actual use, when the lightning arrester body 1 vibrates, the vibration is transmitted to the first piston piece 26 through the supporting rod 27, the first piston piece 26 is pushed to move downward in the first chamber 22, and the hydraulic oil in the first chamber 22 is extruded into the second chamber 23 through the plurality of communication holes 212, the hydraulic oil extruded into the second chamber 23 pushes the second piston piece 210 to move upward in the second chamber 23 and compresses the gas in the second chamber 23, at this time, the gas in the second chamber 23 can play the role of air spring and can buffer the vibration of the lightning arrester body 1, thereby improving the anti-vibration performance of the lightning arrester.

[0036] When the shock of the lightning arrester body 1 disappears, the compressed gas in the second chamber 23 will push the second piston piece 210 back, and the hydraulic oil in the second chamber 23 will be squeezed back into the first chamber 22, thereby pushing the first piston piece 26 to move upward in the first chamber 22. During the upward movement of the first piston piece 26 in the first chamber 22, the blocking piece 29 will be moved into the gas outlet channel 24 and gradually block the gas outlet channel 24 during the movement, thereby playing a throttling role, gradually reducing the amount of gas in the gas outlet channel 24, thereby gradually slowing down the rising speed of the first piston piece 26, until the blocking piece 29 completely blocks the gas outlet channel 24, and the gas is discharged from the throttling channel 25, thereby avoiding secondary impact during rebound and avoiding secondary injury.

[0037] When the lightning arrester body 1 is severely and greatly shocked, the support rod 27 can further push the first piston piece 26 to move downward in the first chamber 22, further squeeze the hydraulic oil in the first chamber 22 into the second chamber 23 through the plurality of communication holes 212, and push the second piston piece 210 to further compress the gas in the second chamber 23 to move upward in the second chamber 23. When the second piston piece 210 compresses the gas in the second chamber 23 to move to the limit position, in order to avoid impact due to buffer failure, at this time, the first piston piece 26 drives the first magnetic piece 222 to move to the lower part of the first chamber 22, so that the first magnetic piece 222 corresponds to the position of the third magnetic piece 224. The first magnetic piece 222 can be attracted to the third magnetic piece 224 by the opposite poles of the magnetic poles to drive the adjusting plate 221 and the blocking block 220 to unblock the gas passing hole 217. At this time, the gas in the second chamber 23 can enter the third chamber 214 and push the third piston piece 215 to compress the first elastic piece 216 to move upward in the third chamber 214. At this time, the first piston piece 26 can continue to move downward for buffering, thereby improving the buffering effect.

[0038] When the first piston piece 26 is about to move to the bottom of the first chamber 22, the first piston piece 26 can drive the plurality of blocking plates 213 to gradually block the corresponding communication holes 212, thereby playing a throttling role, gradually reducing the amount of oil in the communication holes 212, thereby again slowing down the descending speed of the first piston piece 26, thereby performing multi-stage buffering, avoiding impact due to buffer failure in the case of severe shock, thereby further improving the buffering effect and prolonging the service life of the lightning arrester.

[0039] When the vibration disappears, the first elastic member 216 will push the third piston member 215 back during the process of the first piston member 26 returning to the initial position, pushing the gas in the third chamber 214 back to the second chamber 23, when the first piston member 26 is located at the initial position at the top of the first chamber 22, the first magnetic member 222 corresponds to the position of the second magnetic member 223, the first magnetic member 222 can repel the adjusting plate 221 and the plugging block 220 through the same polarity of the second magnetic member 223 to unplug the gas hole 217, thereby restoring the buffer rigidity.

[0040] In summary, through the setting of the buffer assembly 2, when the lightning arrester body 1 is subjected to severe and large vibration, the plugging of the gas hole 217 can be removed, the buffer rigidity can be adjusted, the first piston member 26 can continue to move downward for buffering, the buffering effect is improved, and when the first piston member 26 moves to the bottom of the first chamber 22, the communication hole 212 is gradually plugged, which plays a throttling role, so that the oil output in the communication hole 212 gradually decreases, thereby slowing down the descending speed of the first piston member 26 again, thereby performing multi-stage buffering, avoiding impact caused by buffering failure in the case of large vibration, thereby further improving the buffering effect and prolonging the service life of the lightning arrester.

[0041] Embodiment two In actual use, when the lightning arrester continuously receives high voltage and cannot completely release energy, the generated energy will gradually accumulate, which will cause the lightning arrester to overheat, and in severe cases, the internal components may be burned or the shell may explode, causing the lightning arrester to fail, therefore, the device described in the above embodiment is improved in this embodiment.

[0042] Reference Figures 1 to 9 Further comprising an adjusting assembly 3, the adjusting assembly 3 comprises a conductive plate 31, the bottom of the support rod 27 is provided with a mounting groove 32, the inside of the mounting groove 32 is fixedly connected with a conductive member 33 electrically connected with the lightning arrester body 1, the conductive member 33 is electrically connected with a grounding wire, and the conductive plate 31 is fixedly connected in the mounting groove 32.

[0043] Reference Figures 3 to 9 The inside of the support rod 27 is provided with an adjusting cavity 34, a communication groove 35 is provided between the adjusting cavity 34 and the mounting groove 32, the inside of the adjusting cavity 34 is slidably connected with a fourth piston member 36, a second elastic member 37 is connected between the side of the fourth piston member 36 close to the mounting groove 32 and the adjusting cavity 34, the side of the fourth piston member 36 close to the mounting groove 32 is fixedly connected with a support plate 38 slidably connected in the communication groove 35, the top of the support plate 38 is fixedly connected with a conductive block 39, and the inside of the adjusting cavity 34 is filled with a thermal expansion material, such as a thermal expansion gas, on the side of the fourth piston member 36 away from the second elastic member 37.

[0044] When the conductive block 39 moves to the inside of the mounting groove 32, the two sides of the conductive block 39 are in contact with the conductive piece 33 and the conductive plate 31 respectively, and the conductive piece 33 and the conductive plate 31 are in conduction.

[0045] With reference to Figure 2 Figure 3 And Figure 7 The top of the mounting seat 21 is fixedly connected with a mounting block 310, the top of the mounting block 310 is provided with a sliding groove 311, the inside of the sliding groove 311 is fixedly embedded with a conductive sheet 312, the conductive sheet 312 is electrically connected with the standby grounding wire, and one end of the conductive plate 31 located outside the mounting groove 32 is slidably connected in the sliding groove 311; When the first piston piece 26 is located at the top position of the first cavity 22, the conductive plate 31 is not in contact with the conductive sheet 312, and when the first piston piece 26 drives the supporting rod 27 to move downward in the first cavity 22, the conductive plate 31 can slide in the sliding groove 311 synchronously, and the conductive plate 31 can be in contact with the conductive sheet 312.

[0046] In actual use, when the lightning arrester body 1 is subjected to a continuous high-voltage current, the resistance in the lightning arrester body 1 decreases sharply, and the lightning arrester body 1 discharges energy to the ground through the conductive piece 33 and the grounding wire. When the lightning arrester body 1 cannot completely release the energy, the generated energy will gradually accumulate, causing the lightning arrester body 1 to generate high temperature. The high temperature is transmitted to the adjusting cavity 34 through the supporting rod 27, the temperature in the adjusting cavity 34 rises, and the thermal expansion material in the adjusting cavity 34 expands. After the thermal expansion material expands, the fourth piston piece 36 is pushed to compress the second elastic piece 37 to move, and the supporting plate 38 and the conductive block 39 are driven to extend out of the communication groove 35. When the supporting plate 38 drives the conductive block 39 to move to the inside of the mounting groove 32, the two sides of the conductive block 39 are in contact with the conductive piece 33 and the conductive plate 31 respectively, so that the conductive piece 33 and the conductive plate 31 are in conduction. When the lightning arrester body 1 is subjected to a high-voltage current, vibration will be generated, which is transmitted to the first piston piece 26 through the supporting rod 27, so that the supporting rod 27 pushes the first piston piece 26 to move downward in the first cavity 22. In the process of moving downward, the supporting rod 27 drives the conductive plate 31 to slide synchronously in the sliding groove 311, the conductive plate 31 can be in contact with the conductive sheet 312, the conductive piece 33 can be electrically connected with the standby grounding wire, the grounding resistance is reduced, and the energy is discharged to the ground through the grounding wire, so that the energy discharge speed is improved, the risk of thermal accumulation of internal elements of the lightning arrester and breakdown of insulating materials is reduced, and the service life of the lightning arrester is further prolonged.

[0047] In summary, by adjusting the setting of the adjusting assembly 3, when the arrester body 1 is subjected to a continuous high-voltage current, the conductive part 33 can be electrically connected to the standby grounding wire, the grounding resistance is reduced, the energy is discharged to the ground at the same time, the energy discharge speed is improved, the risk of thermal accumulation of internal elements of the arrester and breakdown of insulating materials is reduced, and the service life of the arrester is further prolonged.
