Description

Technical Field

[0001] This utility model relates to the field of surge arrester technology, specifically to a novel surge arrester with a robust structure. Background Technology

[0002] A surge arrester is an extremely important overvoltage protection device in a power system. Its main function is not to "avoid lightning strikes," but to protect electrical equipment (such as transformers, switchgear, generators, cable terminals, etc.) from damage caused by lightning overvoltages (direct or induced lightning strikes) or operational overvoltages (caused by switch operation, faults, etc.).

[0003] The surge arrester is equipped with an equipotential ring at its top. Its annular external structure increases the workload during transportation. To prevent damage to the equipotential ring caused by collisions during transportation, the surge arrester and equipotential ring need to be transported separately to increase the convenience of transportation. In the later assembly stage, a stable connection between the surge arrester and the equipotential ring is required. Therefore, a new type of surge arrester with a stable structure is provided. Utility Model Content

[0004] The purpose of this invention is to provide a novel surge arrester with a robust structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A novel surge arrester with a robust structure includes an insulating mounting base. A surge arrester body is mounted on the top of the insulating mounting base. An equalizing ring is mounted on the top of the surge arrester body via a connecting mechanism, and the connecting mechanism is connected to the top of the surge arrester body. A protective mechanism for protecting the top of the connecting mechanism is inserted into the top of the connecting mechanism. The connecting mechanism includes a mounting plate inserted into the top of the insulating mounting base. A plurality of connecting rods are rotatably connected at equal intervals around the outer ring of the mounting plate. A plug-in block is fixedly connected to the end of each connecting rod furthest from the mounting plate.

[0007] Using the above technical solution, when the equipotential ring needs to be installed, the workers first unfold the foldable connecting mechanism to the working state, then firmly install its base on the top flange of the surge arrester body. After that, the bottom end of the connecting mechanism is connected to the equipotential ring, and then the connecting mechanism is restricted to increase the ease of connection of the device. After that, the protection mechanism is installed on the top of the connecting mechanism to protect the top of the connecting mechanism, further increasing the protection of the device.

[0008] A further improvement of the present invention is that the connecting mechanism further includes a connecting sleeve that is inserted into and cooperates with the plug-in block, and several connecting sleeves are equidistantly sleeved on the equalizing ring. The connecting sleeves and the plug-in block are connected to each other by connecting bolts. The top of the mounting plate is provided with a limiting seat, and the mounting plate and the limiting seat are connected to each other by fixing bolts.

[0009] Using the above technical solution, when installing the equalizing ring, the connecting rod on the mounting plate is unfolded, and then several connecting sleeves are equidistantly fitted onto the equalizing ring. Next, the insertion block at the end of the connecting rod is inserted into the top of the connecting sleeve, and then the insertion block and the connecting sleeve are fastened together using connecting bolts, completing the installation of the device. Finally, the limiting seat is mated to the top of the mounting plate, thereby limiting the connecting rod, increasing the installation stability of the connecting rod, and maintaining the installation strength of the device.

[0010] A further improvement of this utility model is that: the bottom end of the plug-in block is provided with a connecting block, and the top end of the connecting sleeve is provided with a groove that engages with the connecting block at the bottom end of the plug-in block.

[0011] Using the above technical solution, the connecting block at the bottom of the plug-in block is arranged in three sections, and the top of the connecting sleeve is provided with a groove that interlocks with the connecting block at the bottom of the plug-in block, further increasing the connection area between the plug-in block and the connecting sleeve, thereby increasing the connection fit between the plug-in block and the connecting sleeve, and increasing the connection strength and stability between the two.

[0012] A further improvement of this utility model is that: the outer ring of the limiting seat is provided with limiting grooves at equal intervals for limiting the connecting rod, and the end of the connecting rod away from the plug block is provided with a vertical rod that cooperates with the limiting groove.

[0013] Using the above technical solution, multiple sets of limiting grooves evenly distributed on the outer circumference of the limiting seat form a ring array-type constraint structure. When the vertical rod at the top of the connecting rod is embedded in the groove, the groove wall applies a uniform elastic compressive force to the vertical rod in the circumferential direction, which can improve the structural fit stability under dynamic working conditions.

[0014] A further improvement of this utility model is that the top of the limiting seat is provided with a groove for installation and cooperation with the fixing bolt.

[0015] By adopting the above technical solution, the groove set at the top of the limiting seat can increase the fit of the fixing bolt installation, and the setting of the groove can increase the convenience of the fixing bolt installation, making it easier for the staff to operate.

[0016] A further improvement of the present invention is that the protective mechanism includes a protective top cover disposed on the top of the limiting seat, the bottom end of the protective top cover is provided with plug-in rods that are equidistant from each other and interlock with the limiting seat, and the top end of the limiting seat is provided with mating holes that are equidistant from each other and interlock with the plug-in rods.

[0017] Using the above technical solution, when installing the protective mechanism, the staff will install the protective top cover on the top of the limiting seat, and the bottom of the protective top cover will be connected to the limiting seat through the plug rod, which increases the fit between the two and prevents rainwater from accumulating on the top of the limiting seat in rainy weather, causing corrosion of the parts. The setting of the mating hole can increase the fit between the protective top cover and the limiting seat.

[0018] A further improvement of this utility model is that the bottom end of each plug rod is provided with a groove to facilitate the plug rod's insertion into the mating hole.

[0019] By adopting the above technical solution, the groove at the bottom of the plug rod can deform during the plug-in process, increasing the convenience of the plug rod during the plug-in process.

[0020] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0021] 1. This utility model increases the convenience of connecting the surge arrester body and the equalizing ring through the setting of the connecting mechanism. The retractable connecting mechanism increases the convenience of the device during transportation, avoiding collisions during transportation that could cause deformation of the equalizing ring and the connecting mechanism, thus affecting the later assembly of the device. In addition, the expandable connecting mechanism can increase the connection fit between the connecting mechanism and the equalizing ring, and improve the uniformity of the force on the equalizing ring, thereby increasing the overall stability and strength of the device.

[0022] 2. By setting up a protective mechanism, this utility model can prevent the seat from directly contacting rainwater, thus avoiding the accumulation of rainwater, preventing prolonged outdoor work, increasing the corrosion of the device, and extending the service life of the device. In addition, the protective mechanism can prevent debris from getting stuck in the connection gaps of the connecting mechanism, increasing the ease of disassembly and assembly of the device.
