Description

Technical Field

[0001] This utility model belongs to the field of surge arrester technology, and in particular relates to a surge arrester with a quick-connect structure. Background Technology

[0002] In the protection of power transmission and distribution lines and electrical equipment in power systems, surge arresters are used as key overvoltage protection devices and are widely used in various scenarios such as substations, distribution rooms, and transmission lines.

[0003] With the continuous expansion of power grids and the increasing demands for operation and maintenance efficiency, the traditional installation methods of surge arresters have gradually revealed many drawbacks. Traditional surge arresters mostly use bolt fastening, flange connection and other fixing methods. The installation process requires the use of a variety of tools, requires a high level of operational proficiency from the installers, and is cumbersome and time-consuming. Especially in high-altitude operations or emergency repair scenarios, excessively long installation time will increase operational risks and power outage losses. Therefore, a surge arrester with a quick-installation structure is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a surge arrester with a quick-installation structure. By setting up a clamping component, specifically, under the drive of the fastening component, lever two drives the meshing plate and the fixed clamping plate to move synchronously closer to the surge arrester body through the slot frame two: the meshing plate and the meshing teeth mesh to achieve circumferential fixation, and the fixed clamping plate is embedded in the fixed ring groove to form axial limitation. The double structure enhances the installation firmness and stability. The three evenly distributed components apply uniform clamping force, reducing the possibility of local damage, ensuring the coaxiality of the installation and the working performance of the surge arrester. This solves the problem that traditional surge arresters mostly use bolt fastening, flange connection and other fixing methods. The installation process requires the use of multiple tools, requires a high level of skill from the installers, and the steps are cumbersome and time-consuming.

The bottom of the drive ring 216 is fixedly connected to the side of the three slot frame 1 217 away from the lever 231. The outer surface of the internal threaded sleeve 212 is provided with anti-slip texture.

[0030] The mounting mechanism 2 also includes a positioning fine-tuning component 22, which is installed inside the cavity of the support sleeve 211. The bottom of the outer surface of the surge arrester body 112 is inserted into the inside of the support sleeve 211. A pressing protrusion 113 and a positioning ring groove 114 are formed on the bottom of the outer surface of the surge arrester body 112. The pressing protrusion 113 is located below the positioning ring groove 114. The positioning fine-tuning component 22 includes three levers 221 disposed inside the cavity of the support sleeve 211. The three levers 221 are respectively connected to hinges at their centers via pins. Support bracket 222, three hinged supports 222 are fixedly connected to the inner wall of support sleeve 211 on their opposite sides. Each of the three support sleeves 211 has a ring hook 223 fixedly connected to its outer bottom. Lever 221 is V-shaped. Ring springs 224 are fitted inside the three ring hooks 223. Three slide rails 228 are fixedly connected to the top of the inner wall of support sleeve 211. L-shaped push rods 227 are slidably connected inside each of the three slide rails 228. The centers of the three L-shaped push rods 227 are rotatably connected to the ends of lever 221 via pins. A connecting block 225 is fixedly connected to each of the corresponding sides. The inner bottom of lever one 221 contacts the outer surface of the extrusion convex surface 113. Roller balls 226 are rotatably connected to the inner side of each of the three connecting blocks 225 away from the L-shaped push rod 227. The outer surfaces of the three roller balls 226 contact the inner wall of the positioning ring groove 114. The side of the connecting block 225 away from the L-shaped push rod 227 contacts the bottom of the outer surface of the surge arrester body 112. Lever one 221 is located above the drive ring 216, and the drive ring 216 is located above lever two 231. The extrusion convex surface 113 extrudes the inner bottom of lever one 221. L-shaped push rod 227 drives connecting block 225 and ball bearing 226 to approach surge arrester body 112. Ball bearing 226 is embedded in positioning ring groove 114 to complete initial positioning. Ring spring 224 applies continuous elastic tension to lever 221 through ring hook 223 to ensure that ball bearing 226 is tightly fitted with positioning ring groove 114, improving positioning stability and allowing for fine adjustment of installation angle. It is suitable for various scenarios. When this component is inserted, it automatically completes positioning fine adjustment without additional operation, simplifying the steps, reducing work abnormalities caused by installation deviation, improving equipment installation reliability and work stability, and extending the service life of surge arrester.

[0031] A specific application of this embodiment is as follows: During use, the operator first aligns the surge arrester body 112 with the top opening of the support sleeve 211 and inserts it vertically into the cavity of the support sleeve 211. During the insertion process, the pressing convex surface 113 at the bottom of the surge arrester body 112 will contact the inner bottom of the three levers 221 and generate a pressing force, causing the levers 221 to rotate around the hinge bracket 222. When the levers 221 rotate, their top will push the L-shaped push rod 227 through the pin. Slide along slide rail 228 toward the arrester body 112. L-shaped push rod 227 drives connecting block 225 and ball 226 to move synchronously until ball 226 is embedded in positioning ring groove 114 on the outer surface of arrester body 112. At this time, ring spring 224 applies continuous elastic tension to lever 221 through ring hook 223 to ensure that ball 226 is tightly fitted with the inner wall of positioning ring groove 114, completing the initial positioning and angle fine adjustment of arrester body 112 and ensuring installation accuracy.

[0032] After initial positioning, the worker grasps the anti-slip texture on the outer surface of the internal threaded sleeve 212 and rotates it clockwise. Since the internal threaded sleeve 212 is rotatably connected to the support sleeve 211 via the annular groove 213, and its inner wall is threadedly engaged with the external threaded block 215, the rotation causes the two external threaded blocks 215 to slide downwards along the opening 214. The external threaded blocks 215 then drive the drive ring 216 downwards synchronously, causing the three slots 217 at the bottom of the drive ring 216 to pull the lever 2 downwards. One end of 31 causes lever 231 to rotate around hinge bracket 232. The other end of lever 231 pushes slot frame 236 to slide inward along slide rail 233 via pin. Slot frame 236 drives meshing plate 234 and fixed clamping plate 235 to move synchronously until meshing plate 234 is tightly meshed with meshing teeth 115 on the outer surface of arrester body 112. At the same time, fixed clamping plate 235 is embedded in fixed ring groove 116 to achieve double fastening of arrester body 112 and complete the entire installation process.

[0033] When disassembly or maintenance is required, simply rotate the internal threaded sleeve 212 counterclockwise to move the external threaded block 215 and drive ring 216 upward. After the lever 231 loses its tension, it resets under its own weight and reaction force. The engagement plate 234 and the fixing clamp 235 release the fixation of the surge arrester body 112. At this time, the surge arrester body 112 can be directly removed from the support sleeve 211, making the operation convenient and efficient.
