Description

Technical Field

[0001] This invention relates to the field of high-voltage surge arrester technology, specifically to a seismic-resistant high-voltage surge arrester. Background Technology

[0002] High-voltage surge arresters are devices used in power systems to protect electrical equipment from overvoltage damage. They are mainly used for lightning and overvoltage protection of high-voltage transmission lines, transformers, switchgear, and other equipment. When a high-voltage surge arrester encounters a lightning strike or switching overvoltage, it quickly switches to a low-resistance state, discharging the large current generated by the overvoltage into the ground through the grounding device. It then returns to a high-resistance state, ensuring that the equipment insulation is not damaged. Common types include zinc oxide surge arresters, which are characterized by fast response and strong current carrying capacity. They are key protective devices for lightning strikes and overvoltages in power systems and are crucial for maintaining the stable operation of power systems.

[0003] Most high-voltage surge arresters currently use a single rigid fixed structure, which is rigidly connected to the installation foundation only by bolts or brackets. They lack an effective buffering mechanism. When they encounter external forces such as earthquakes and strong winds, the vibration energy will be directly transmitted to the arrester body, which can easily lead to problems such as loosening of internal components and cracking of porcelain bushings. In severe cases, it can even cause insulation failure. Therefore, we propose an earthquake-resistant high-voltage surge arrester. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an earthquake-resistant high-voltage surge arrester. This solves the problem that most existing high-voltage surge arresters use a single rigid fixed structure, which is rigidly connected to the installation foundation only by bolts or brackets. This lacks an effective buffering mechanism, and when subjected to external forces such as earthquakes or strong winds, the vibration energy is directly transmitted to the arrester body, which can easily lead to problems such as loosening of internal components and cracking of porcelain bushings. In severe cases, it can even cause insulation failure.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a seismic-resistant high-voltage surge arrester, comprising a mounting rod and a high-voltage surge arrester body, wherein the high-voltage surge arrester body is located above the mounting rod, and a seismic-resistant device is provided on the lower surface of the high-voltage surge arrester body. The seismic-resistant device includes a stabilizing plate, which is fixedly connected to the lower surface of the high-voltage surge arrester body. A positioning rod is fixedly connected to the lower surface of the stabilizing plate, and a locking block is fixedly connected to the lower end of the positioning rod. A slot is provided on the upper surface of the mounting rod, and a limiting groove is provided on the inner bottom wall of the slot. Both the slot and the limiting groove are adapted to the locking block. The locking block is inserted into the limiting groove and rotated to fit into the limiting groove. A screw is threadedly connected to the inner wall of the stabilizing plate. The lower end of the screw is rotatably connected to a stop block. This solution constructs a multi-dimensional seismic protection system through a composite design of rigid fixing and elastic buffering. The compression spring can directly absorb external vibration energy, reducing the impact force transmitted to the arrester body. The sliding cooperation between the stabilizing plate and the limiting sleeve, combined with the rigid support of the screw and the stop block, can disperse the remaining vibration to the mounting rod, avoiding local stress concentration. When the vibration amplitude is large, the pneumatic damping effect of the sleeve and the piston block, and the secondary buffering of the tension spring further weaken the impact, forming a stepped seismic resistance mechanism. Compared with the traditional single seismic resistance structure, the impact resistance performance is significantly improved. It can effectively cope with complex working conditions such as strong earthquakes and external collisions, and ensure the stable operation of the high-voltage arrester in harsh environments.

[0008] Preferably, a limiting sleeve is slidably connected to the positioning rod, the stabilizing plate is slidably connected to the inner wall of the limiting sleeve, and a storage groove adapted to the card block is provided on the lower surface of the limiting sleeve.

[0009] Preferably, a compression spring is fixedly connected to the lower surface of the stabilizing plate, and the lower end of the compression spring is fixedly connected to the inner bottom wall of the limiting sleeve.

[0010] Preferably, a knob is fixedly connected to the upper end of the screw.

[0011] Preferably, a positioning magnet is installed on the inner bottom wall of the limiting sleeve, and the positioning magnet is magnetically attracted to the abutment block.

[0012] Preferably, the surface of the limiting sleeve is provided with a stabilizing device for limiting the displacement of the limiting sleeve. The device ensures installation accuracy and stability through a multi-positioning structure. The rotational engagement of the locking block and the limiting groove achieves initial fixation. The magnetic adsorption of the positioning magnet and the abutment block accurately calibrates the position of the abutment block, avoiding installation deviation. The locking fit between the bolt and the buckle prevents the piston block from loosening. The storage groove design of the limiting sleeve protects the locking block from external damage. This combination of mechanical fixing, magnetic positioning and locking protection not only simplifies the installation process, but also resists displacement caused by factors such as vibration and wind during long-term use, ensuring that the surge arrester is always in the preset working position, reducing the risk of failure caused by unstable installation, and extending the service life of the equipment.

[0013] Preferably, the stabilizing device includes a sleeve installed on one side of the limiting sleeve, two symmetrically arranged sleeve blocks are slidably connected to the mounting rod, and piston blocks are fixedly connected to the sides of the two sleeve blocks that are close to each other. One end of the piston block is inserted into the sleeve, and two symmetrically arranged partitions are fixedly connected to the inner wall of the sleeve.

[0014] Preferably, each of the two piston blocks is fixedly connected to a retaining bracket on the side away from the mounting rod. A protrusion is fixedly connected to the end of the retaining bracket away from the piston block, and a bolt is threaded onto the inner wall of the protrusion. The adjustable structure of the device makes it suitable for various installation environments. By rotating the knob to adjust the screw position, the angle of the stop block can be flexibly adjusted to adapt to different ground conditions. The sliding design of the limiting sleeve and the elastic extension and contraction of the compression spring can accommodate a certain range of installation errors. The adsorption effect of the positioning magnet reduces the precision requirements during installation, facilitating rapid construction. In addition, the storage groove protects the locking block, and the anti-slip protrusion stabilizes the slider, further enhancing the durability and maintenance convenience of the device. It balances the professional requirements of high-voltage equipment with the practicality of on-site operation, broadening its application range in different voltage levels and installation scenarios.

[0016] Preferably, a tension spring is fixedly connected to the upper end of the slider, the upper end of the tension spring is fixedly connected to the inner top wall of the positioning sleeve, and an anti-slip protrusion is fixedly connected to the lower surface of the slider.

[0017] In summary, the technical effects and advantages of this invention are as follows:

[0018] 1. In this invention, the solution constructs a multi-dimensional seismic protection system through a composite design of rigid fixing and elastic buffering. The compression spring can directly absorb external vibration energy, reducing the impact force transmitted to the arrester body. The sliding cooperation between the stabilizing plate and the limiting sleeve, combined with the rigid support of the screw and the stop block, can disperse the remaining vibration to the mounting rod, avoiding local stress concentration. When the vibration amplitude is large, the pneumatic damping effect of the sleeve and the piston block, and the secondary buffering of the tension spring further weaken the impact, forming a stepped seismic protection mechanism. The impact resistance performance is significantly improved compared with the traditional single seismic protection structure, which can effectively cope with complex working conditions such as strong earthquakes and external collisions, and ensure the stable operation of the high-voltage arrester in harsh environments.

The rotational engagement of the locking block and the limiting groove achieves initial fixation. The magnetic adsorption of the positioning magnet and the abutment block precisely calibrates the position of the abutment block, avoiding installation deviations. The locking fit between the bolt and the buckle prevents the piston block from loosening. The storage groove design of the limiting sleeve protects the locking block from external damage. This combination of mechanical fixing, magnetic positioning, and locking protection not only simplifies the installation process but also resists displacement caused by factors such as vibration and wind during long-term use, ensuring that the surge arrester is always in the preset working position, reducing the risk of failure caused by unstable installation, and extending the service life of the equipment.

[0020] 3. In this invention, the adjustable structure of the device makes it suitable for various installation environments. By rotating the knob to adjust the screw position, the angle of the stop block can be flexibly adjusted to adapt to different ground conditions.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] refer to Figures 1-8 The diagram illustrates a seismic-resistant high-voltage surge arrester, comprising a mounting rod 1 and a surge arrester body 2. The surge arrester body 2 is positioned above the mounting rod 1. To enhance the seismic resistance of the arrester, a seismic-resistant device 3 is provided on its lower surface. This device includes a stabilizing plate 31, which is fixedly connected to the lower surface of the surge arrester body 2. A positioning rod 32 is fixedly connected to the lower surface of the stabilizing plate 31, and a locking block 33 is fixedly connected to the lower end of the positioning rod 32. A slot 38 is provided on the upper surface of the mounting rod 1, and a limiting groove 39 is provided on the inner bottom wall of the slot 38. These slots 38 and limiting grooves 39 are adapted to the locking block 33, allowing the locking block 33 to be inserted into the limiting groove 39 and rotated into it, thereby realizing the seismic resistance of the arrester. For fixation, this solution constructs a multi-dimensional seismic protection system through a composite design of rigid fixation and elastic buffering. The compression spring 34 can directly absorb external vibration energy, reducing the impact force transmitted to the arrester body. The sliding cooperation between the stabilizing plate 31 and the limiting sleeve 35, combined with the rigid support of the screw 311 and the stop block 310, can disperse the remaining vibration to the mounting rod 1, avoiding local stress concentration. When the vibration amplitude is large, the pneumatic damping effect of the sleeve 47 and the piston block 42, and the secondary buffering of the tension spring 45 further weaken the impact, forming a stepped seismic protection mechanism. Compared with the traditional single seismic protection structure, the impact resistance performance is significantly improved, which can effectively cope with complex working conditions such as strong earthquakes and external collisions, and ensure the stable operation of the high-voltage arrester in harsh environments.

[0032] To further improve stability, the inner wall of the stabilizing plate 31 is threaded with a screw 311, and the lower end of the screw 311 is rotatably connected to a stop block 310. This structural design helps to absorb and disperse vibrations to a certain extent before they are transmitted to the ground when subjected to external impact, through the cooperation of the screw 311 and the stop block 310, thereby protecting the arrester body.

[0033] In addition, a limiting sleeve 35 is slidably connected to the positioning rod 32, and the stabilizing plate 31 is slidably connected to the inner wall of the limiting sleeve 35. The lower surface of the limiting sleeve 35 is provided with a storage groove 36 that matches the card block 33. This design allows the card block 33 to be stored in the storage groove 36 of the limiting sleeve 35 when not in use, thus avoiding unnecessary damage to it.

[0034] To further enhance the seismic resistance, a compression spring 34 is fixedly connected to the lower surface of the stabilizing plate 31. The lower end of the compression spring 34 is fixedly connected to the inner bottom wall of the limiting sleeve 35. When the surge arrester is subjected to vibration, the compression spring 34 can absorb some of the vibration energy and reduce the impact of vibration on the surge arrester body.

[0035] For ease of operation, a knob 312 is fixedly connected to the upper end of the screw 311. Users can adjust the position of the screw 311 by rotating the knob 312, thereby adjusting the angle of the stop block 310 to adapt to different installation environments.

[0036] To improve positioning accuracy, a positioning magnet 37 is installed on the inner bottom wall of the limiting sleeve 35. The positioning magnet 37 is magnetically attracted to the stop block 310. This magnetic attraction design ensures that the stop block 310 is accurately positioned in the required position under the action of the screw 311, thereby improving the accuracy and stability of the installation.

[0037] To limit the displacement of the limiting sleeve 35, a stabilizing device 4 is provided on the surface of the limiting sleeve 35 to limit its displacement. The stabilizing device 4 includes a sleeve 47 installed on one side of the limiting sleeve 35, two symmetrically arranged sleeve blocks 41 slidably connected to the mounting rod 1, and piston blocks 42 fixedly connected to the sides of the two sleeve blocks 41 that are close to each other. One end of the piston block 42 is inserted into the sleeve 47, and two symmetrically arranged partitions 411 are fixedly connected to the inner wall of the sleeve 47. This structural design can effectively prevent the limiting sleeve 35 from displacing when subjected to external forces, ensuring its stability during installation. The device ensures installation accuracy through a multi-positioning structure. For stability, the rotational engagement of the locking block 33 and the limiting groove 39 achieves initial fixation. The magnetic adsorption of the positioning magnet 37 and the abutment block 310 precisely calibrates the position of the abutment block 310, avoiding installation deviation. The locking engagement of the bolt 410 and the buckle 48 prevents the piston block 42 from loosening. The storage groove 36 of the limiting sleeve 35 protects the locking block 33 from external damage. This combination of mechanical fixation, magnetic positioning, and locking protection not only simplifies the installation process but also resists displacement caused by factors such as vibration and wind during long-term use, ensuring that the surge arrester is always in the preset working position, reducing the risk of failure caused by unstable installation, and extending the service life of the equipment.

[0038] To further improve stability, each piston block 42 is fixedly connected to a retaining bracket 48 on the side away from the mounting rod 1. A protrusion 49 is fixedly connected to the end of the retaining bracket 48 away from the piston block 42. A bolt 410 is threaded onto the inner wall of the protrusion 49. Through the tightening action of the bolt 410, the piston block 42 can be firmly fixed in the sleeve 47, preventing loosening during use. The adjustable structure of the device makes it suitable for various installation environments. By rotating the knob 312 to adjust the position of the screw 311, the angle of the abutment block 310 can be flexibly adjusted. To adapt to different ground conditions, the sliding design of the limiting sleeve 35 and the elastic extension and contraction of the compression spring 34 can accommodate a certain range of installation errors. The adsorption effect of the positioning magnet 37 reduces the precision requirements during installation, facilitating rapid construction. In addition, the protection of the card block 33 by the storage groove 36 and the stabilizing effect of the anti-slip protrusion 412 on the slider 46 further enhance the durability and maintenance convenience of the device, taking into account both the professional requirements of high-voltage equipment and the practicality of on-site operation, thus broadening its application range in different voltage levels and different installation scenarios.

[0039] To achieve more precise positioning, positioning sleeves 43 are fixedly connected to both sides of the limiting sleeve 35. A slider 46 is slidably connected to the inner wall of the positioning sleeve 43. An air guide tube 44 is fixedly connected to the upper surface of the positioning sleeve 43. The end of the air guide tube 44 away from the positioning sleeve 43 is fixedly connected to the upper surface of the sleeve 47. The sleeve 47 is connected to the positioning sleeve 43 through the air guide tube 44. The slider 46 is slidably connected to the inner wall of the positioning sleeve 43. This design of the air guide tube 44 ensures smooth airflow between the sleeve 47 and the positioning sleeve 43, thereby achieving more precise positioning.

[0040] To improve the smoothness of sliding, a tension spring 45 is fixedly connected to the upper end of the slider 46. The upper end of the tension spring 45 is fixedly connected to the inner top wall of the positioning sleeve 43, and an anti-slip protrusion 412 is fixedly connected to the lower surface of the slider 46. The tension spring 45 can provide a certain cushioning effect, while the anti-slip protrusion 412 can increase the friction between the slider 46 and the positioning sleeve 43, preventing the slider 46 from slipping off during sliding.

[0041] Working principle of the invention: During installation, first insert the locking block 33 at the lower end of the positioning rod 32 into the slot 38 of the mounting rod 1. After rotation, the locking block 33 is embedded in the limiting groove 39, achieving initial fixation between the high-voltage surge arrester body 2 and the mounting rod 1. At the same time, the limiting sleeve 35 is pressed against the mounting rod 1 under the elastic force of the compression spring 34. When not in use, the locking block 33 can be stored in the storage groove 36 of the limiting sleeve 35 to avoid damage. By rotating the knob 312, the screw 311 is rotated, causing the lower end of the abutment block 310 to move down until it is magnetically attracted to the positioning magnet 37 on the inner bottom wall of the limiting sleeve 35. The magnetic positioning ensures that the abutment block 310 is accurately attached to the mounting surface, further enhancing the fixing effect.

[0042] When subjected to external impact or vibration, the compression spring 34 first absorbs part of the vibration energy through its own deformation, reducing the impact force transmitted to the stabilizing plate 31. At the same time, the sliding fit between the stabilizing plate 31 and the limiting sleeve 35 buffers the vibration. The rigid connection between the screw 311 and the stop block 310 disperses the remaining vibration energy to the mounting rod 1, avoiding concentrated action on the arrester body.

[0043] If the vibration amplitude is large, the limiting sleeve 35 is forced to push the sleeve 47 to squeeze the piston block 42. The piston block 42 slides along the sleeve block 41 of the mounting rod 1. The displacement range of the piston block 42 is limited by the partition frame 411 to prevent the limiting sleeve 35 from shaking excessively. At the same time, the air pressure change in the sleeve 47 is transmitted to the positioning sleeve 43 through the air pipe 44, pushing the slider 46 to compress the tension spring 45. The rebound force of the tension spring 45 further offsets the vibration. The anti-slip protrusion 412 enhances the friction between the slider 46 and the positioning sleeve 43 to ensure the stability of the sliding process. The cooperation between the bolt 410 and the buckle 48 can lock the position of the piston block 42 to avoid loosening caused by long-term vibration. The overall structure achieves anti-vibration protection in high-voltage environments through multiple mechanisms such as spring buffering, magnetic positioning, air pressure damping, and rigidity dispersion, ensuring the safety and reliability of the surge arrester operation.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
