Description

Technical Field

[0001] This utility model belongs to the field of lightning protection technology, specifically a lightning protection device for substation lines. Background Technology

[0002] Substations are crucial nodes in the power system, responsible for the transmission and distribution of electrical energy. Lightning, as a natural phenomenon, poses a serious threat to the power system. A direct strike by lightning on substation lines or equipment can cause equipment damage, fire, or even explosion, thereby affecting the stable operation of the entire power system. By taking effective lightning protection measures, such as surge arresters, lightning current can be quickly diverted to the ground, preventing damage to equipment and lines from lightning strikes, thus ensuring the stable operation of the power system.

[0003] In existing surge arresters, a common installation method involves securing the arrester to an angle steel bracket using a nut that engages with the lead wire spool at the bottom. However, the lead wire spool at the bottom of the arrester is typically quite slender. After aligning with the pre-drilled hole on the angle steel bracket, it is tightened with a nut. Due to the limited diameter of the lead wire spool, the contact area with the angle steel bracket is relatively small. While this small-area connection method can meet the installation requirements of the surge arrester to some extent, it lacks lateral support structures, resulting in insufficient stability under extreme weather conditions such as strong winds and heavy rain.

[0004] Therefore, those skilled in the art have proposed a lightning protection device for substation lines to address the problems raised in the background art. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a substation line lightning protection device to solve the problems in the prior art where the connection area between the lightning arrester and the angle steel is small and there is a lack of lateral support structure, resulting in insufficient stability when facing extreme weather conditions such as strong winds and heavy rain.

[0006] A lightning protection device for substation lines includes an angle steel and a surge arrester body. An assembly hole is provided in the middle of the top of the angle steel. The surge arrester body is located above the angle steel. Both the top and bottom of the surge arrester body are connected to lead wire spools for wiring. The lead wire spool at the bottom passes through the assembly hole and is threaded with a nut. A fixing sleeve is provided on the outside of the lead wire spool at the top. Multiple sets of horizontal shafts are circumferentially and equidistantly connected to the outer wall of the fixing sleeve. One end of each set of horizontal shafts is connected to a balance ring. An oblique support structure that is connected and limited to the angle steel is provided on the outside of the balance ring.

[0007] Preferably, the middle of each of the two lead wire spools is fitted with a crimp terminal for connection with the circuit, and a threaded sleeve for limiting the crimp terminal is threaded onto it.

[0008] Preferably, fixing holes are provided at both ends of the top of the angle steel to assist external fasteners in fixing the angle steel.

[0009] Preferably, the inclined support structure includes a rotating component, a threaded cylinder, a telescopic rod, and a hook. The outer side of the balance ring is rotatably connected to the threaded cylinder via the rotating component. The telescopic rod is inserted at the bottom end of the threaded cylinder. The outer wall of the telescopic rod is provided with an external thread that mates with the threaded cylinder. The bottom end of the telescopic rod is connected to a hook.

[0010] Preferably, the rotating component includes ear plates, a rotating shaft, a connecting sleeve, a connecting shaft, and a connecting disc. Ear plates are provided in pairs on the outer side of the balance ring. The rotating shaft is rotatably disposed between the two ear plates. A connecting sleeve is provided in the middle of its outer side. One end of the connecting shaft is connected to the connecting sleeve, and the other end is connected to the connecting disc. The bottom of the connecting disc is threadedly connected to the top of the threaded sleeve through a bearing.

[0011] Preferably, the top of the angle steel is symmetrically provided with a retaining seat, which is configured as an inverted U-shape, with its two vertical ends connected to the angle steel and its horizontal section engaged with a hook.

[0012] Preferably, a rotating ring is provided on the outer side of the threaded cylinder, and multiple sets of arc-shaped slots for gripping are circumferentially and equidistantly provided on the rotating ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model features an inclined support structure connected to an angle steel via a balance ring on the outer side of the surge arrester body. Utilizing the cooperation of a rotating component, a threaded cylinder, a telescopic rod, and a hook, the threaded cylinder is driven to rotate relative to the telescopic rod. The telescopic rod then causes the hook to retract relative to the threaded cylinder. During the retraction process, the telescopic rod causes the hook to engage with the locking seat on the angle steel, facilitating on-site assembly with the angle steel. This significantly enhances the connection strength between the surge arrester and the angle steel, thereby increasing the stability of the surge arrester in its installation position.

[0015] 2. In this utility model, the main connecting section of the oblique support mechanism that provides auxiliary connection to the surge arrester body consists of a threaded sleeve and a telescopic rod. The threaded sleeve can rotate relative to the telescopic rod with the cooperation of the rotating part, so that the length of its oblique connection can be adjusted according to the overall installation height of the surge arrester body, thereby improving the overall adjustability and reducing the limitations during its assembly.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] As attached Figure 1 To be continued Figure 4 As shown:

[0024] This utility model provides a lightning protection device for substation lines, including an angle steel 1 and a surge arrester body 2. An assembly hole 3 is provided in the middle of the top of the angle steel 1. The surge arrester body 2 is located above the angle steel 1. Both the top and bottom of the body are connected to lead wire shafts 4 for wiring. The lead wire shaft 4 at the bottom passes through the assembly hole 3 and is threaded with a nut. A fixing sleeve 5 is provided on the outside of the lead wire shaft 4 at the top. Multiple sets of horizontal shafts 6 are circumferentially and equidistantly connected to the outer wall of the fixing sleeve 5. One end of each set of horizontal shafts 6 is connected to a balance ring 7. An oblique support structure that is connected and limited to the angle steel 1 is provided on the outside of the balance ring 7.

[0025] refer to Figure 1 and Figure 2 Both lead wire shafts 4 are fitted with crimp terminals 8 for connection to the circuit in the middle, and threaded sleeves 9 for limiting the crimp terminals 8 are threaded on them.

[0026] The threaded sleeve 9 facilitates the pressing of the crimp terminal 8 onto the lead wire shaft 4, and the crimp terminal 8 facilitates the connection of the lightning protection line.

[0027] refer to Figure 1 The angle steel 1 has fixing holes 10 at both ends of its top, which are used to assist external fasteners in fixing the angle steel 1.

[0028] The fixing hole 10 facilitates the positioning and installation of the angle steel 1, thus improving the ease of installation.

[0029] refer to Figure 1The inclined support structure includes a rotating component, a threaded cylinder 11, a telescopic rod 12, and a hook 13. The outer side of the balance ring 7 is rotatably connected to the threaded cylinder 11 through the rotating component. The telescopic rod 12 is inserted at the bottom end of the threaded cylinder 11. The outer wall of the telescopic rod 12 is provided with an external thread that is threaded to the threaded cylinder 11. The bottom end of the telescopic rod 12 is connected to the hook 13.

[0030] In the specific operation process, the threaded cylinder 11 is driven to rotate relative to the telescopic rod 12. During the rotation, the telescopic rod 12 moves inward relative to the threaded cylinder 11, and during the movement, it drives the hook 13 to move synchronously.

[0031] refer to Figure 2 and Figure 4 The rotating component includes ear plates 14, rotating shaft 15, connecting sleeve 16, connecting shaft 17 and connecting disc 18. Ear plates 14 are arranged in pairs on the outer side of the balance ring 7. The rotating shaft 15 is rotatably arranged between the two ear plates 14. The connecting sleeve 16 is arranged in the middle of its outer side. One end of the connecting shaft 17 is connected to the connecting sleeve 16, and the other end is connected to the connecting disc 18. The bottom of the connecting disc 18 is threadedly connected to the top of the threaded sleeve 9 through a bearing.

[0032] The rotating component allows the threaded cylinder 11 to change its oblique support angle according to the position of the card holder 19, thus facilitating adaptive adjustment based on specific installation conditions and improving overall adjustability.

[0033] refer to Figure 2 The top of the angle steel 1 is symmetrically provided with a bracket 19, which is set in an inverted U-shape. Its two vertical ends are connected to the angle steel 1, and its horizontal section is engaged with the hook 13.

[0034] When engaging the hook 13 with the horizontal section of the seat 19, first rotate the threaded cylinder 11 until the hook 13 at its bottom is placed on the seat 19. Then rotate the threaded cylinder 11 relative to the telescopic rod 12 so that the telescopic rod 12 retracts relative to the threaded cylinder 11, thereby engaging the hook 13 with the seat 19.

[0035] refer to Figure 3 A rotating ring 20 is provided on the outer side of the threaded cylinder 11. The rotating ring 20 has multiple sets of arc-shaped slots for gripping that are circumferentially equidistant.

[0036] The curved groove facilitates gripping of the rotating ring 20, thereby making it easier to rotate the threaded cylinder 11 using the plane of the rotating ring 20, which improves the convenience of assembly and connection.

[0037] Working principle: When installing the surge arrester body 2 onto the angle steel 1, first, pass the lead wire spool 4 at the bottom of the surge arrester body 2 through the mounting hole 3 on the angle steel 1, then screw the nut onto the bottom of the lead wire spool 4, and then put the crimping terminal 8 onto the ends of the two lead wire spools 4 respectively. Finally, screw on the threaded sleeve 9 to limit and tighten the crimping terminal 8, thus completing the initial connection of the surge arrester body 2. Then, according to the position of the clamp 19, determine the angle of the oblique support, that is, rotate the threaded cylinder 11 around the rotating shaft 15, so that the threaded sleeve 9 passes through the connecting... The connecting plate 18, connecting shaft 17, and connecting sleeve 16 drive the rotating shaft 15 to rotate. During the rotation, the threaded cylinder 11 drives the telescopic rod 12 and the bottom hook 13 to be placed on the mounting base 19. Then, hold the rotating ring 20 with one hand and the telescopic rod 12 with the other hand. When the rotating ring 20 rotates, it drives the threaded cylinder 11 to rotate relative to the telescopic rod 12. During the rotation, the telescopic rod 12 retracts towards the threaded cylinder 11, thereby causing the hook 13 at its bottom end to lock into the mounting base 19, thus completing the oblique support assembly of the surge arrester body 2.
