Description

Technical Field

[0001] This utility model relates to the field of power supply system technology, and in particular to a drop-out surge arrester. Background Technology

[0002] Surge arresters mainly work on the principle of air breakdown. When the lightning protection system receives a lightning strike, the strong electric field generated by the lightning will accelerate the free electrons in the sky to a level that exceeds the breakdown electric field strength of the conductor element, causing the charge to flow to the arrester. After the charge is absorbed by the conductor head of the arrester, it will form a conductor loop with the nearby grounding pin and continue to flow into the ground, thus playing the role of lightning protection.

[0003] With the rapid development of the power industry and the continuous increase in power load, the requirements for surge arresters are also constantly increasing. Especially in environments with extremely high requirements for lightning protection, such as high-rise buildings, communication base stations, and wind farms, the fixed position of traditional surge arresters can no longer meet the needs of modern power facilities for lightning protection. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drop-out surge arrester.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drop-out surge arrester includes a sliding box, a rotatable threaded rod inside the sliding box, a handle at one end of the threaded rod located at the outer end of the sliding box, two sliding support plates sleeved on the threaded rod, a surge arrester body installed on the top of the sliding support plates, and two mounting semicircular sleeves at the bottom of the sliding box.

[0007] In addition, a preferred structure is that each of the two sliding support plates is embedded with a nut pair, the nut pair is sleeved on the threaded rod, and sliding blocks are provided on both sides of the sliding support plate.

[0008] In addition, a preferred structure is that sliding grooves are provided at both ends of the inner side of the sliding box, and sliding blocks are slidably disposed in the sliding grooves.

[0009] In addition, a preferred structure is that two connecting strips are symmetrically arranged at the bottom of the sliding box, a connecting rod is provided inside the connecting strip, and a semi-circular sleeve is fitted on the connecting rod.

[0010] In addition, a preferred structure is that the mounting semicircular sleeve has three mounting holes, a threaded post is inserted into the mounting holes, and a threaded cap is threadedly connected to the other side of the threaded post on the other side of the mounting semicircular sleeve.

[0011] Furthermore, in a preferred configuration, the materials used to manufacture the main body 1 of the drop-out surge arrester are all insulating materials.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, the lateral position adjustment of the drop-out surge arrester is achieved through the mutual cooperation between the threaded rod and the nut pair inside the sliding box. This design not only improves the flexibility of the surge arrester, but also allows the position of the surge arrester to be adjusted in different environments, making it convenient for installation and use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 A drop-out surge arrester includes a sliding box 2, a rotatable threaded rod 6 inside the sliding box 2, a handle 5 at one end of the threaded rod 6 located at the outer end of the sliding box 2, two sliding support plates 4 sleeved on the threaded rod 6, a surge arrester body 1 installed on the top of the sliding support plates 4, and two mounting semicircular sleeves 3 at the bottom of the sliding box 2.

[0021] Each of the two sliding support plates 4 has a nut pair 42 embedded in it, which is sleeved on the threaded rod 6. Sliding blocks 41 are provided on both sides of the sliding support plate 4.

[0022] Meanwhile, sliding grooves 21 are provided at both ends of the inner side of the sliding box 2, and sliding blocks 41 are slidably arranged in the sliding grooves 21. When the threaded rod 6 rotates, it provides guidance and stability for the lateral movement of the arrester body 1.

[0023] Meanwhile, two connecting strips 7 are symmetrically arranged at the bottom of the sliding box 2, and a connecting rod 8 is provided inside the connecting strip 7, and a semi-circular sleeve 3 is fitted on the connecting rod 8.

[0024] Meanwhile, the mounting semicircular sleeve 3 has three mounting holes 31. Threaded posts 9 are inserted into the mounting holes 31. Threaded caps 10 are threadedly connected to the other side of the mounting semicircular sleeve 3. When it needs to be installed on the power pole, the two mounting semicircular sleeves 3 are tightened with the threaded posts 9 and threaded caps 10 to fix the installation.

[0025] Furthermore, the materials used to manufacture the main body 1 of the drop-out surge arrester are all insulating materials.

[0026] In this embodiment, by opening and fitting the two semi-circular mounting sleeves 3 onto the power pole, and then inserting the threaded post 9 into the mounting hole 31, the threaded cap 10 is then screwed into the threaded post 9 for threaded connection. This eliminates the need for screwdrivers during high-altitude operations, avoiding potential hazards. Next, the handle 5 is cranked to rotate the threaded rod 6, causing the nut assembly 42 to move laterally. This allows the sliding support plate 4 to move the arrester body 1 laterally until it reaches the desired position. Simultaneously, the sliding blocks 41 on both sides of the sliding support plate 4 move within the sliding groove 21, providing guidance and strong support for the movement of the arrester body 1. This prevents the arrester body 1 from swaying during movement and causing potential hazards. The position of the arrester body 1 can be adjusted according to the specific installation environment, greatly improving the flexibility of the drop-out arrester.

[0027] In this invention, the lateral position adjustment of the drop-out surge arrester is achieved through the mutual cooperation between the threaded rod 6 and the nut pair 42 inside the sliding box 2. This design not only improves the flexibility of the surge arrester, but also allows the position of the surge arrester to be adjusted in different environments, making it convenient for installation and use.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
