Description

Technical Field

[0001] This utility model relates to the field of high-voltage surge arrester technology, and in particular to a high-voltage surge arrester that can flexibly add or remove insulating sheaths. Background Technology

[0002] High-voltage surge arresters are electrical devices used to protect electrical equipment from high transient overvoltage hazards during lightning strikes and to limit the follow current time and often the follow current amplitude. The insulating sheaths on them are an important part for distributing high-voltage current. Traditional high-voltage surge arresters adopt a one-piece design structure, which is manufactured as a whole. Therefore, this structure makes it difficult to flexibly adjust its size according to actual needs in actual use. In other words, the number of insulating sheaths cannot be flexibly increased or decreased, making it difficult to flexibly adjust the size of the surge arrester's conductive surface according to actual usage requirements. Surge arresters of the same size can only be used in suitable locations, making it difficult to achieve a universal effect. As a result, various surge arresters of different sizes have been developed, increasing the corresponding usage costs.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0028] A high-voltage surge arrester with flexibly adjustable insulating sheaths includes a surge arrester body 1. Mounting grooves 3 are provided on both sides of the top of the surge arrester body 1. Mounting blocks 4 are engaged inside the mounting grooves 3. Insulating sheaths 2, fitted onto the surface of the surge arrester body 1, are fixedly connected to the outer sides of the two mounting blocks 4. Movable cavities 5, evenly spaced, are provided on one side of the inner cavity of the mounting grooves 3. Locking pins 6, adapted to the mounting blocks 4, are slidably installed inside the movable cavities 5. A spring 7 is fixedly connected to one side of the locking pins 6. The end of the spring 7 away from the locking pins 6 is fixedly connected to the inner wall of the movable cavities 5. A sliding groove 8 is provided at the bottom of the inner cavity of the movable cavities 5. A support block 9, adapted to the mounting blocks 4, is slidably installed inside the sliding groove 8. The top of the support block 9 is fixedly connected to the locking pins 6. A locking groove 14, adapted to the locking pins 6, is provided on the side of the mounting blocks 4 facing the locking pins 6.

[0029] The specific usage process is as follows: This high-voltage surge arrester adjusts its current-conducting area by increasing or decreasing the number of insulating sheaths, allowing the size of the arrester to be adjusted according to actual working requirements. This, in turn, adjusts the arrester's working power through a mechanical mechanism, achieving a universal effect. This allows the arrester to be applied in various fields, thus meeting diverse usage needs. When increasing or decreasing the number of insulating sheaths 2, first disassemble the entire arrester from its installation position. Then, completely remove all components installed on the arrester body 1, including the top cover 18, fastening bolts 19, and other related parts. Then, the user inserts their fingers into the groove 10 and pinches the two levers 12 relative to each other. This causes the two levers 12 to move in the corresponding adapter slots 1. Within the movable cavity 5, the connecting rods 13 slide along the corresponding lever 12, pulling the locking pin 6 within the movable cavity 5 and compressing the spring 7. The end of the locking pin 6 then moves out of the mounting block 4, and the support block 9 moves from the bottom of the mounting block 4 into the sliding groove 8, releasing the locking of the mounting block 4 and the insulating umbrella sleeve 2. The corresponding number of insulating umbrella sleeves 2 can then be removed by moving them upwards along the surface of the surge arrester body 1. The mounting block 4 moves upwards from the mounting groove 3, thus removing the insulating umbrella sleeves 2, reducing their number, decreasing the conductive surface of the surge arrester, and minimizing the size of the barrier. To meet actual usage requirements, when increasing the number of insulating umbrella sleeves 2, the first part follows the above process. After the user squeezes the lever 12 to move the locking pin 6 into the movable cavity 5 and the support block 9 into the sliding groove 8, the corresponding number of insulating umbrella sleeves 2 can be sequentially fitted onto the surface of the surge arrester body 1. The mounting block 4 will be inserted into the mounting groove 3 and continue to be inserted downwards until all the insulating umbrella sleeves 2 are fitted. At this time, for easy installation, the surge arrester can be laid horizontally, and then the installation position and spacing between the insulating umbrella sleeves 2 can be adjusted sequentially. After all adjustments are completed, the lever 12 is released. At this time, under the action of the spring 7, the locking pin 6 will be ejected from the inner cavity of the movable cavity 5 and inserted into the locking groove 14 on the mounting block 4. At the same time, the support block 9 will be inserted into the sliding groove 8. Block 9 is also inserted into the bottom of mounting block 4 to provide support for mounting block 4, preventing mounting block 4 and insulating umbrella sleeve 2 from moving freely during use. It also works with locking pin 6 to improve the stability and firmness of the installation of mounting block 4 and insulating umbrella sleeve 2, providing convenience for users. Because the top part of the lever 12 is located within the groove 10, it does not extend to the top of the arrester body 1, thus facilitating the subsequent installation of the top cover 18. Simultaneously, bolt holes are provided at the bottom of the inner cavity of the groove 10 for installing fastening bolts 19. In this way, the top cover 18 can be installed onto the arrester body 1 using the fastening bolts 19, providing convenience for users. When the user is disassembling, they can move the two levers 12 within the adapter groove 11.Then, the lever 12 moves the connecting rod 13 within the movable cavity 5. Finally, the connecting rod 13 moves the locking pin 6 out of the mounting block 4, releasing the lock. This allows for quick and easy removal of the insulating umbrella sleeve 2 from the surge arrester body 1, providing convenience for the user. The base 17 is used to install the surge arrester, providing support and fixation to ensure its stability during operation. The base plate 171 can be quickly and easily fixed to the required position using the mounting bolts 173. The disconnector body 15 and the surge arrester can be quickly installed onto the mounting sleeve 172 using the fastening bolts 19, allowing the surge arrester to be quickly installed onto the base 17, thus facilitating the user's assembly and disassembly.

[0030] Therefore, a structural design that allows for flexible adjustment of the number of insulating sheaths is adopted. By increasing or decreasing the number of insulating sheaths, the current-conducting area of ​​the surge arrester can be adjusted, so that the size of the surge arrester can be adjusted according to actual working needs, achieving a universal effect. This allows the surge arrester to be used in a variety of fields, reducing the cost of use and providing convenience for users.

At the same time, bolt holes are provided at the bottom of the inner cavity of the groove 10 for installing fastening bolts 19. In this way, the top cover 18 can be installed on the arrester body 1 by fastening bolts 19, providing convenience for users' work and use.

[0033] A lever 12 is movably installed inside the adapter slot 11. One end of the locking pin 6 is fixedly connected to a connecting rod 13. The end of the connecting rod 13 away from the locking pin 6 passes through the adapter slot 11 and is fixedly connected to the lever 12.

[0034] Specifically, the adapter slot 11, the lever 12, and the connecting rod 13 are configured so that when the user is disassembling the device, the two levers 12 are squeezed and moved within the adapter slot 11. Then, the levers 12 drive the connecting rod 13 to move within the movable cavity 5. Finally, the connecting rod 13 drives the locking pin 6 to move out of the mounting block 4 and release the lock, thereby facilitating the quick and easy removal of the insulating umbrella cover 2 from the surge arrester body 1 and providing convenience for the user's work.

[0035] The bottom of the surge arrester body 1 is fixedly installed with a disconnector body 15, and a bracket 16 is detachably installed on the surface of the disconnector body 15.

[0036] Specifically, the disconnector body 15 and bracket 16 are designed to support the surge arrester, further securing it in its working position, improving its operational stability, and providing convenience for users. The disconnector body 15, when an abnormal fault occurs in the surge arrester, utilizes the power frequency short-circuit current to activate the disconnector, automatically disconnecting its grounding terminal, thereby taking the surge arrester out of operation, preventing further escalation of the accident, and providing a visible disconnection indicator for the faulty surge arrester, facilitating timely fault location, maintenance personnel, and maintenance and replacement.

[0037] The bottom of the detacher body 15 is detachably mounted with a base 17. The base 17 includes a base plate 171 located below the detacher body 15. The top of the base plate 171 is fixedly connected with a mounting sleeve 172. The top edge of the base plate 171 is provided with mounting bolts 173 arranged in a triangular pattern.

[0038] Specifically, the base 17 is used to install the surge arrester, providing support and fixation to ensure the stability of the surge arrester during operation. The base plate 171 can be quickly and easily fixed to the required position using mounting bolts 173. The disconnector body 15 and the surge arrester can be quickly installed on the mounting sleeve 172 using fastening bolts 19, allowing the surge arrester to be quickly installed on the base 17, thus providing convenience for the user's disassembly and assembly work.

[0039] The top of the surge arrester body 1 is provided with a top cover 18. Fastening bolts 19 are provided through the top of the top cover 18 and the bottom of the disconnector body 15. The disconnector body 15 is fixedly installed on the mounting sleeve 172 by the fastening bolts 19, and the top cover 18 is fixedly installed on the top of the surge arrester body 1 by the fastening bolts 19.

[0040] Specifically, the top cover 18 and the fastening bolts 19 are designed so that the top cover 18 is made of insulating material and can be fixed to the top of the surge arrester body 1 to provide insulation for the surge arrester, improve the safety of the surge arrester, and provide convenience for the user's work.
