Description

Technical Field

[0001] This utility model belongs to the field of surge arrester installation technology, specifically relating to a surge arrester installation mechanism. Background Technology

[0002] In power systems, transmission line towers, as crucial structures supporting power transmission lines, are constantly exposed to the natural environment and are highly susceptible to natural disasters such as lightning strikes. Lightning strikes can not only cause line tripping and power outages, but in severe cases, they can also damage power equipment and threaten the safe and stable operation of the power grid. Surge arresters, as important overvoltage protection devices, are widely used on transmission line towers. Their function is to quickly divert lightning current to the ground when a lightning strike occurs, thereby protecting lines and equipment from lightning damage. Currently, surge arresters are typically installed by fixing the arrester body to a specially designed mounting base, which is then bolted to the angle steel beam of the transmission line tower. Additionally, the surge arrester is equipped with connecting wires that must be electrically connected to the conductors on the line to achieve its lightning protection function.

[0003] However, traditional surge arrester installation mechanisms have many drawbacks. Specifically, when installing surge arresters, operators need to climb to the high-altitude tower to work, and use manual tools such as wrenches to tighten the bolts between the mounting base and the angle steel beam, as well as between the clamp assembly (used to fix the surge arrester connecting wire and conductor) and the conductor. This process is not only difficult and labor-intensive, but also poses serious safety hazards, such as the risk of falling from heights and electric shock. More importantly, the traditional installation method requires the line to be de-energized to avoid electric shock accidents during installation, which further affects the operating efficiency of the power system. Therefore, this utility model proposes a surge arrester installation mechanism. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0016] Please see Figures 1 to 4 This is the first embodiment of the present utility model, which provides the following technical solution: a surge arrester installation mechanism, comprising... The mounting base assembly fixed on the angle steel beam 4 of the tower includes a top bracket 11, an integrated L-shaped bottom bracket 12 set on the bottom surface of the top bracket 11, a locking block 13 slidably set on the inner side of the L-shaped bottom bracket 12, a threaded rod 14 rotatably installed on the bottom surface of the locking block 13 and extending to the bottom of the L-shaped bottom bracket 12, and a pinch ring 15 fixed on the bottom surface of the threaded rod 14. The top bracket 11 is clamped on the top surface of the angle steel beam 4 of the tower, and the locking block 13 is locked on the inner side of the angle steel beam 4 of the tower through the threaded rod 14. A surge arrester 3 is installed on the top right end of the top bracket 11. And a clamp assembly 2 fixed to the tower conductor 5 and connected to the top connecting line 31 of the surge arrester 3.

[0017] In this embodiment, preferably, the wire clamp assembly 2 includes a side base plate 21, an integral arc-shaped top seat 22 disposed at the top of the side base plate 21, an integral support plate 25 disposed inside the side base plate 21, a U-shaped inner clamp seat 23 slidably disposed inside the side base plate 21 and located between the support plate 25 and the arc-shaped top seat 22, a threaded rod 24 rotatably mounted on the bottom surface of the U-shaped inner clamp seat 23 and extending through to the bottom of the support plate 25, and a pinch ring 26 fixed to the bottom surface of the threaded rod 24. The bottom end of the side base plate 21 is connected to the connecting line 31, the arc-shaped top seat 22 is fitted on the top of the tower conductor 5, and the U-shaped inner clamp seat 23 is locked below the tower conductor 5 by the threaded rod 24. The side base plate 21, the arc-shaped top seat 22, and the support plate 25 are all made of conductive metal, which can smoothly realize the connection between the connecting line 31 and the tower conductor 5. The surface of the support plate 25 is provided with a threaded hole 2 for the threaded rod 24 to be turned, so that the threaded rod 24 can be smoothly rotated and turned.

[0018] In this embodiment, preferably, the left end of the top bracket 11 is provided with an integrated edge clip 111, and the edge clip 111 is clipped on the outside of the tower angle steel beam 4, which can ensure the stability of the top bracket 11 when it is clipped on the top of the tower angle steel beam 4 and prevent the top bracket 11 from being displaced laterally. The left end of the locking block 13 is provided with an inclined guide surface 132, so that when the L-shaped bottom bracket 12 and the top bracket 11 are pushed towards the tower angle steel beam 4 during actual installation, the inclined guide surface 132 can play a guiding role, making it easier for the tower angle steel beam 4 to be pushed between the locking block 13 and the top bracket 11.

[0019] In this embodiment, preferably, the bottom surface of the top bracket 11 is provided with multiple integrated strip-shaped anti-slip protrusions 112, and the top surface of the locking block 13 is provided with multiple integrated strip-shaped anti-slip protrusions 131. This allows the strip-shaped anti-slip protrusions 112 and 131 to provide an anti-slip effect and ensure the stability of the installation after the locking block 13 and the top bracket 11 are subsequently locked and fixed to the pole angle steel beam 4.

[0020] In this embodiment, preferably, the surface of the L-shaped bottom bracket 12 is provided with a threaded hole for the threaded rod 14 to pass through, and the right end of the top bracket 11 is provided with a bolt hole 113 for the installation of the surge arrester 3.

[0021] In summary, in actual use, this installation mechanism first fixes the bottom end of the surge arrester 3 to the right end of the top bracket 11 with bolts on the bottom surface, completing the connection between the surge arrester 3 and the mounting base assembly. Then, the connecting wire 31 is connected to the side base plate 21 with bolts, completing the connection between the connecting wire 31 and the clamp assembly 2. This completes the preparation work for this installation mechanism on the bottom surface. Then, the surge arrester 3 is clamped with the insulated operating rod in the prior art, and the surge arrester 3 is lifted to one side of the tower angle steel beam 4. The surge arrester 3 is pushed towards the tower angle steel beam 4, so that the top edge of the tower angle steel beam 4 can enter between the top bracket 11 and the locking block 13. At this time, the pinch ring 15 is clamped with another insulated operating rod and rotated clockwise, causing the locking block 13 to slide upward until the locking block 13 and the top bracket 11 can be firmly locked on the tower angle steel beam 4. This completes the initial installation and fixing of the surge arrester 3. Then... Clamp the pinch ring 26 with the insulated operating rod, and hang the arc-shaped top seat 22 at the top of the side base plate 21 on the tower conductor 5. Then, rotate the pinch ring 26 clockwise with the insulated operating rod, causing the U-shaped inner clamp 23 to slide upwards until the U-shaped inner clamp 23 and the arc-shaped top seat 22 can be firmly locked on the tower conductor 5. The clamp assembly 2 can then be locked on the tower conductor 5. Since the side base plate 21 and the arc-shaped top seat 22 are made of conductive metal, the connecting wire 31 can be connected to the tower conductor 5 through the side base plate 21 and the arc-shaped top seat 22. This completes the installation of the installation mechanism and the installation of the surge arrester 3. The operator does not need to climb to the top of the tower to complete the installation of the surge arrester 3 using the insulated operating rod, which greatly reduces labor intensity and safety risks. At the same time, the installation method of this application does not require power outage, avoiding economic losses and power supply reliability issues caused by power outages. Example 2

[0022] Please see Figures 1 to 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the wire clamp assembly 2 also includes an anti-slip pad 27.

The top surface of the anti-slip pad 27 is evenly provided with a plurality of strip-shaped anti-slip grooves 272, so that after the U-shaped inner clamp seat 23 is locked with the tower conductor 5, the anti-slip pad 27 can play an anti-slip and fastening effect, ensuring the installation stability of the wire clamp assembly 2.

[0023] In this embodiment, preferably, an installation structure is provided between the anti-slip pad 27 and the U-shaped inner clamp 23. The installation structure includes a T-shaped clip 271, a circular through hole 231, and a circular locking hole 232. The bottom of the anti-slip pad 27 is provided with two integrated T-shaped clips 271, both of which are made of rubber and will undergo elastic deformation when squeezed. The surface of the U-shaped inner clamp 23 has two circular through holes 231, and the top surface of the U-shaped inner clamp 23 has a circular locking hole 232 for the T-shaped clips 271 to pass through. The bottom end of the T-shaped clip 271 passes through the circular locking hole 232 into the circular through hole 231, which can realize the stable installation of the anti-slip pad 27.

[0024] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
