Description

Technical Field

[0001] This invention relates to the field of surge arrester installation technology, specifically to a fixing device for installing zinc oxide surge arresters. Background Technology

[0002] Zinc oxide surge arresters are overvoltage protection devices, mainly composed of zinc oxide varistors, usually encapsulated in porcelain or composite jackets. Due to their excellent nonlinear resistance characteristics, these surge arresters are widely used in power systems to limit overvoltages and protect equipment from voltage surges.

[0003] Zinc oxide surge arresters must be connected in parallel between the protected equipment (such as transformers, switches, busbars, etc.) and the ground. One end of the surge arrester is connected to the high-voltage conductor or equipment terminal to be protected via a high-voltage down conductor. This connection point is usually the bolt on the upper end of the surge arrester body. The other end is connected to the grounding device (grounding grid, grounding electrode) via a grounding down conductor. Surge arresters are often installed on the crossarm of a pole-mounted disconnector or a high-voltage lead crossarm using a single bolt and nut.

[0018] 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.

[0019] Please see Figure 1-13 The present invention provides a technical solution: including a surge arrester body 1 and a connection drive assembly 2. A power connection assembly 3 is connected to the top of the surge arrester body 1 and an insulating base connection assembly 4 is connected to the bottom. In use, the power connection assembly 3 and the insulating base connection assembly 4 need to be pre-installed at both ends of the surge arrester body 1. The connecting drive assembly 2 includes a crossarm assembly 5, a pressing assembly 6, and a drive assembly 7. The pressing assembly 6 is connected to the bottom end of the crossarm assembly 5, the drive assembly 7 is connected to the bottom end of the pressing assembly 6, and the insulating seat connecting assembly 4 is connected to the top end of the crossarm assembly 5. The crossarm assembly 5 and the pressing assembly 6 are connected to the high-voltage crossarm. The drive assembly 7 drives the pressing assembly 6 and the crossarm assembly 5 to connect and fix the high-voltage crossarm, which is used to connect with the insulating seat connecting assembly 4 at the bottom end of the surge arrester body 1. Reference Figure 4 and Figure 6 As shown, the connection assembly 3 includes a connection cover 9 connected to the top of the surge arrester body 1. A directional adjustment assembly 10 is connected to the top of the connection cover 9, and a sealing gasket 91 is connected to the bottom of the connection cover 9. The compression spring 16 and the connection cover 9 are inserted into the bolt at the top of the surge arrester body 1 and connected to the bolt using a connecting nut 17. Pushing the connection cover 9 downwards compresses the compression spring 16, thereby using a reverse force to push it upwards from the bottom inner side of the connection cover 9, ensuring a stable connection while providing cushioning. A positioning assembly 11 is connected to the top of the directional adjustment assembly 10, which allows the connection to be adjusted... The high-voltage terminal 15 of the high-voltage conductor is quickly connected. The top of the cover 9 is connected to the inside of the directional assembly 10 and a compression spring 12 is connected. The top of the compression spring 12 is connected to the top plate 13 and the inside of the top plate 13 is connected to the contact element 14. The contact element 14 is connected to the bolt at the top of the surge arrester body 1. The elasticity of the compression spring 12 moves upward with the top plate 13, thereby driving the contact element 14 to be in a state of contact with the high-voltage terminal 15. The elasticity of the compression spring 12 can use the contact element 14 to tightly press the high-voltage terminal 15 against the inside of the positioning assembly 11. After the connection is completed, the top is sealed with the cover plate 18, which can play a certain role in waterproofing and dustproofing. Reference Figure 7 and Figure 13As shown, the directional adjustment assembly 10 includes a sealing cover 105 connected to the top of the connecting cover 9 and a limiting ratchet 102 rotatably mounted on the top of the connecting cover 9. The sealing cover 105 is fixedly mounted on the top of the connecting cover 9. A rotating tube 101 is rotatably mounted inside the sealing cover 105. A ratchet tooth 103 is connected to the outer ring of the bottom end of the rotating tube 101. The limiting ratchet 102 meshes with the ratchet tooth 103, thereby allowing the rotating tube 101 to rotate in one direction and preventing it from reversing, thus adjusting the direction. A torsion spring shaft is connected to the top of the connecting cover 9 for limiting... The ratchet 102 is rotatably mounted at one end of the torsion spring shaft, thereby ensuring the reset effect of the limiting ratchet 102 and maintaining the connection with the ratchet tooth 103. The top end of the limiting ratchet 102 is connected to a limiting pin 104. The top end of the connecting cover 9 is provided with a limiting hole corresponding to the limiting pin 104. After the rotating tube 101 is rotated to adjust its direction, the limiting pin 104 passes through the limiting ratchet 102 and is inserted into the limiting hole, thereby fixing the position of the limiting ratchet 102 and preventing the rotating tube 101 from rotating, thus completing the positioning. The positioning component 11 is fixedly mounted at the top end of the rotating tube 101.

[0020] Reference Figure 6 As shown in the middle section, the positioning component 11 includes an inner slot frame 111. Multiple sets of terminal locking pins 112 are slidably arranged on the inner ring of the inner slot frame 111. An inner ring 114 is connected to the inner side of the inner slot frame 111, and multiple guide pins 115 are connected to the inner side of the inner ring 114. A return spring 113 is connected to the inner side of each terminal locking pin 112. The other end of the return spring 113 is sleeved and connected to one end of each guide pin 115. A slot is provided on one side of the inner slot frame 111 corresponding to the high-voltage terminal 15. When the high-voltage terminal 15 is aligned with the slot on one side of the inner slot frame 111 and pressed down, the terminal locking pins 112 are engaged. 2. Press the high-voltage terminal 15 into the inner slot frame 111 until it passes through each terminal latch 112 and is in contact with the connector 14. After the high-voltage terminal 15 passes through the terminal latch 112, the return spring 113 pushes the terminal latch 112 back to its original position through elasticity, thereby limiting the high-voltage terminal 15 above. The compression spring 12 below pushes the top plate 13 through elasticity, pressing the connector 14 tightly against the bottom of the high-voltage terminal 15. The compression spring 12 is also in a compressed state when the high-voltage terminal 15 is not installed, so the compression spring 12 can be further compressed after the high-voltage terminal 15 is installed, thereby ensuring the compression thrust.

[0021] Reference Figure 8As shown, the insulating base connection assembly 4 includes a connecting base 41, a damping rubber sleeve 42 is provided at the top of the connecting base 41, a plurality of pawls 43 are connected to the top of the connecting base 41, a quick-connect seat 44 is connected to the bottom of the connecting base 41, and a compression kit 45 is connected to the outer ring of the connecting base 41. The surge arrester body 1 is inserted into the damping rubber sleeve 42, and the compression kit 45 is rotated and moved upward through the threaded connection with the outer side of the connecting base 41. As the compression kit 45 moves, it squeezes each pawl 43 inward, thereby tightly holding the insulating base at the bottom of the surge arrester body 1. The damping rubber sleeve 42 located on the inner side plays a protective and anti-slip role. The outer ring of the damping sleeve 42 has a fitting groove 19 corresponding to the pawl 43. The bottom end of the inner side of the damping sleeve 42 is connected to a bottom inner buckle end 20, which can fit perfectly with the bottom end of the insulating base of the surge arrester body 1. Through the setting of the fitting groove 19, the pawl 43 is embedded in the inner side of the damping sleeve 42. The bottom end of the pawl 43 is connected to an elastic end 21. In the uninstalled state, the pawl 43 is tilted outward due to the setting of the elastic end 21, thereby ensuring that the surge arrester body 1 can be well inserted into the damping sleeve 42. The inner side of the top of the pawl 43 is provided with an insulating base inner buckle end 22. When the pawl 43 is clamped, the insulating base inner buckle end 22 can be fastened to the chamfered top of the insulating base of the surge arrester body 1. Figure 5 As shown, to ensure connection stability and prevent movement or detachment, the bottom of the quick-connect bracket 44 is connected to the crossarm assembly 5. The quick-connect bracket 44 can be used to directly connect the insulating base connecting assembly 4 and the crossarm assembly 5 by snap-fit.

[0022] Reference Figure 9 As shown, the crossarm assembly 5 includes a positioning housing 51. A bottom extension bracket 52 is connected to the bottom end of the positioning housing 51. The extension bracket 52 is hollow to facilitate connection with the docking bracket 62. An anti-slip and shock-absorbing pad 53 and a positioning pin 54 are connected between the bottom end of the positioning housing 51 and the bottom extension bracket 52. During installation, the positioning pin 54 can be aligned with the mounting holes on the crossarm to achieve pre-positioning. A limiting unit 55 is connected to the top of the positioning housing 51. The limiting unit 55 allows for quick adjustment of the quick-connect bracket 44. The positioning housing 51 is positioned between the positioning units 55 and the top of the positioning housing 51 is connected to a positioning frame 28. An extrusion pad 30 is connected between the positioning frames 28. A retaining seat 29 is connected to the top of the positioning housing 51 corresponding to the quick-connect seat 44. The quick-connect seat 44 is aligned and snapped between the positioning frames 28. At the same time, the retaining seat 29 is inserted into the quick-connect seat 44. The extrusion pad 30 provides a protective effect. A connecting block 56 is connected to the inside of the positioning housing 51. The connecting block 56 can be connected to the connecting screw 34 in the extrusion assembly 6 to complete the assembly. The limiting unit 55 includes a fixed base 23. A positioning pin 24 is slidably disposed on one side of the fixed base 23 that is close to each other. A spring piece 25 is connected to the side of the positioning pin 24 inside the fixed base 23. A connecting rod 26 is disposed on one side of the spring piece 25. One end of the connecting rod 26 passes through the spring piece 25 and is fixedly connected to the positioning pin 24. The other end of the connecting rod 26 passes through the fixed base 23 and is connected to a limiting head 27. One side of the spring piece 25 is connected to the inner wall of the fixed base 23. The quick-connect seat 44 is engaged with the positioning frame 2. Simultaneously, the positioning pins 24 are squeezed to both sides. After the quick connector 44 is in place, the elasticity of the spring 25 will push the positioning pins 24 to reset, thereby limiting the top of the quick connector 44. When disassembly is required, the connecting rod 26 is pulled by the limiting head 27, thereby pulling the spring 25. After being pulled to a certain force, the spring 25 will rebound backward, thereby driving the positioning pins 24 to retract into the fixed seat 23, so as to facilitate the removal of the quick connector 44. The squeezing assembly 6 is connected to the bottom extension frame 52.

[0023] Reference Figure 10 As shown, the extrusion assembly 6 includes a connecting shell 61, a docking bracket 62 connected to the top of the connecting shell 61, a top frame 63 connected between the docking brackets 62, an anti-slip and shock-absorbing pad 64 connected to the top of the top frame 63, a docking plate 65 connected to the inner side of the connecting shell 61, a mating interface opened at the top of the mating plate 65, and a first contact piece 66 connected to the top of the mating interface. The docking bracket 62 is aligned with the extension frame 52 in the crossarm assembly 5 and inserted. At the same time, the top frame 63 is located between the extension frames 52. A connecting component is connected to the inner side of the docking bracket 62. The connecting component is driven by the driving component 7, so that the top frame 63 and the docking bracket 62 slowly move towards the crossarm assembly 5. Through the cooperation of the first anti-slip and shock-absorbing pad 53 and the second anti-slip and shock-absorbing pad 64, the crossarm is extruded and fixedly clamped, thus completing the splicing and positioning of the crossarm assembly 5 and the extrusion assembly 6. The connecting assembly includes a mounting plate 31 fixedly mounted inside the docking bracket 62 and a connecting screw 34 rotatably mounted on the top of the docking bracket 62. The threads on the connecting screw 34 located on the top of the docking bracket 62 on the same side are reversed, and the bottom end of the connecting block 56 has a corresponding threaded hole corresponding to the connecting screw 34.

A drive gear 33 is connected to the top end of the coupling shaft, and a driven gear 35 is connected to the bottom end of the connecting screw 34. The drive gear 33 meshes with the driven gear 35 on both sides. One side of the micro motor 32 is electrically connected to the contact piece 66 via a wire. A docking groove is provided inside the connecting shell 61. 36. Guided by the directional docking block 39 and the docking groove 36, the drive assembly 7 is docked at the bottom of the extrusion assembly 6. At the same time, the contact piece 2 79 and the contact piece 1 66 are docked. The backup battery 727 in the conversion unit 72 supplies power to the micro motor 32. The micro motor 32 is started by the reversing switch 78, which drives the drive gear 33 to rotate. The rotation of the drive gear 33 drives the driven gears 35 on both sides to rotate, so that the connecting screw 34 rotates when aligned with the threaded hole on one side of the connecting block 56. As the connecting screw 34 rotates, the plug-in bracket 62 will gradually move into the extension bracket 52 to complete the connection. After the crossbeam assembly 5 and the extrusion assembly 6 are docked and fixed, the drive assembly 7 can be removed.

[0024] Reference Figure 11As shown, the drive assembly 7 includes a plug-in housing 71. A partition is connected between the inner walls of the plug-in housing 71. A collection and conversion unit 72 is connected to the top of the partition, and multiple sets of limiting rods 74 are connected to the bottom. Multiple sets of PVDF piezoelectric films 73 are connected to one side of the inner wall of the plug-in housing 71. A drive base shell 75 is rotatably mounted at the bottom of the plug-in housing 71. A connecting cylinder 76 is connected to the inner ring of the drive base shell 75, and multiple spring-loaded hammers 77 are connected to the outer ring of the connecting cylinder 76. As shown in the attached figure, the ends of the spring-loaded hammers 77 are equipped with counterweights. The connecting cylinder 76 is located inside each limiting rod 74. Manually rotating the drive base shell 75 drives the connecting cylinder 76 to rotate. When the connecting cylinder 76 rotates, it drives each spring-loaded hammer 77. The spring-loaded hammers 77 are limited by the limiting rods 74 during rotation. It will bend inward, and as the rotating spring hammer 77 disengages from the limit stop 74, the counterweight end of the spring hammer 77 will strike the surface of the PVDF piezoelectric film 73 through its own elasticity. The PVDF piezoelectric film 73 will generate instantaneous electrical energy due to the impact vibration, and it will be transmitted to the collection and conversion unit 72 for collection. The bottom end of the drive housing 75 is connected to a reversing switch 78, and the top end of the plug-in housing 71 is connected to a pair of contact pieces 79. The reversing switch 78 is electrically connected to the collection and conversion unit 72 and the pair of contact pieces 79. When the drive assembly 7 docks to the bottom end of the extrusion assembly 6, a circuit is formed through the connection of the pair of contact pieces 79 and the first contact piece 66. The micro motor 32 is started by controlling the reversing switch 78, and its forward and reverse rotation can also be controlled. The bottom end of the inner wall of the drive housing 75 is connected to the reversing switch 78 with a wire tube 37.

Each group of PVDF piezoelectric film 73 is electrically connected to two first-stage TVS diodes 722 and one Schottky diode 724. The first-stage TVS diodes 722 absorb high-voltage pulses, and the electrical energy after passing through the Schottky diode 724 is then passed through the second-stage TVS diode 723, which plays a role in preventing residual surges. The DC-DC boost module 726 boosts the electrical energy after passing through the Schottky diode 724 and then charges the backup battery 727. At the same time, the supercapacitor 728 also plays a role in energy storage. The comparator 725 plays a role in keeping the output constant, thereby converting and collecting the electrical energy generated by the PVDF piezoelectric film 73.

[0026] The implementation principle of this application is as follows: In use, the connecting component 3 is first installed on the top of the surge arrester body 1 via the connecting nut 17, and the insulating base connecting component 4 is installed on the bottom of the surge arrester body 1. Then, the worker moves to the crossarm to be installed using climbing tools, inserts the positioning pin 54 into the mounting hole on the crossarm from above, and then the pressing component 6 is connected to the crossarm component 5 from below. Then, by turning on the switch 78, the connecting component is driven, causing the pressing component 6 to gradually move inward toward the crossarm component 5 until the crossarm is clamped, thereby ensuring the connection between the crossarm component 5 and the pressing component 6 and the crossarm. To ensure the stability of the connection, the quick-connect bracket 44 is connected to the positioning frame 28. The quick-connect bracket 44 is then limited and locked by the limiting unit 55, thus completing the installation of the surge arrester body 1. The high-voltage terminal 15 on the equipment to be protected or the high-voltage conductor is then directly locked into the positioning component 11. The directional component 10 can be adjusted according to the angle of the high-voltage terminal 15 to ensure the connection effect. After the installation is completed, the drive component 7 is removed to install the next set of crossarm components 5 and compression components 6. The drive component 7 can store energy by rotating, without the need for additional energy consumption.
