Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to an integrated insulated crossarm disconnector. Background Technology

[0002] In existing power systems, a typical disconnecting switch, as described in application publication number CN102646542A, typically includes a single-insulated post high-voltage disconnecting switch, comprising a first contact and a second contact spaced apart by a certain distance, and a switch for connecting the first and second contacts. It also includes an insulating post, with the first and second contacts respectively installed at opposite ends of the same side of the insulating post and spaced apart from it. One end of the switch is axially connected to the first contact, and the other end is equipped with an interlocking device. The second contact is provided with a latching position that cooperates with the interlocking device. A third support member is provided on the side of the insulating post opposite to the switch.

[0003] Typical insulating crossarms, such as those provided in application document CN213717581U, include a main crossarm and mounting components fixed on the main crossarm, wherein both ends of the main crossarm are provided with combined crossarm mechanisms that can arbitrarily adjust the number and relative position of insulators.

[0004] During installation, the two are usually installed separately. The disconnecting switch is connected to the angle iron of the tower via a third support mounting bolt, while the insulating crossarm is installed in other suitable locations to support electrical equipment such as cables.

[0005] When installing a disconnector on an insulating crossarm, since there is no dedicated mounting structure on the crossarm for adapting to the disconnector, the connection between the two can only be achieved by adding an adapter. These adapters not only increase the difficulty and workload of installation, but also occupy more space. Furthermore, the connection between the adapter and the disconnector is usually a simple mechanical connection, which is prone to loosening and displacement under the influence of long-term environmental factors such as wind, sun, and electrical vibration, thus affecting the stability and reliability of the connection between the disconnector and the insulating crossarm. Utility Model Content

[0006] To address the aforementioned issues and overcome the shortcomings of existing technologies, this application aims to provide an integrated insulated crossarm disconnector. This switch integrates the insulated crossarm and the disconnector into a single design, effectively avoiding the use of additional adapters and significantly reducing installation difficulty and workload. Furthermore, the elimination of adapters reduces space requirements, resulting in a more compact and rational layout of the entire power equipment. Moreover, the integrated design enhances the stability and reliability of the connection between the disconnector and the insulated crossarm. Under the long-term influence of environmental factors such as wind, sun, and electrical vibration, the integrated structure, with its integrity and robustness, can better resist external interference and is less prone to loosening or displacement, thereby ensuring the safe and stable operation of the power system.

[0007] The specific technical solution of this application is an integrated insulated crossarm disconnector, which includes:

The upper connecting plate has a first mounting hole, the middle connecting plate has a second mounting hole, and the lower connecting plate has a third mounting hole. The first mounting hole is fixedly connected to a threaded slot. An operating bolt passes through the second and third mounting holes, and the operating bolt engages with the threaded slot through a thread.

[0011] Furthermore, the disconnector connection and fixing device also includes a guide portion, which includes a flared opening formed by side plates. The guide portion is fixedly connected to the left guide plate and the right guide plate, and the larger end of the flared opening of the guide portion faces the installation direction of the disconnector.

[0012] Furthermore, a clamp is fixedly connected to the middle of the crossarm. The clamp includes a base and an annular band. The base is fixedly connected to the middle of the crossarm. Circular holes are provided at both ends of the base. The two ends of the annular band pass through the circular holes and are fastened with bolts and nuts.

[0014] Furthermore, a positioning pin is formed in the installation direction of the crossbeam, and a positioning hole corresponding to the positioning pin is provided on the mounting vertical plate.

[0015] Furthermore, an operating ring is formed at the bottom end of the operating bolt.

[0016] Furthermore, a washer is provided on the operating bolt.

[0017] Compared with the prior art, the beneficial technical effects of this application are as follows:

[0018] The integrated insulating crossarm of this application is provided with a disconnecting switch fixing device. The disconnecting switch can be easily and detachably connected to the fixing device through its mounting part.

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, in some embodiments, an integrated insulated crossarm disconnector is provided, the integrated insulated crossarm disconnector comprising:

[0029] An insulating crossarm body 1, the insulating crossarm body includes a crossarm 2, and a plurality of disconnecting switch fixing devices 3 are arranged at intervals on the crossarm;

[0030] The disconnector switch 4 has a mounting part 5 formed on it, and the mounting part 5 is detachably connected to the disconnector switch fixing device 3.

[0031] By integrating the insulating crossarm and disconnector into a single design, the installation process is greatly simplified. During installation, workers no longer need to perform complex installation and commissioning operations on the insulating crossarm and disconnector separately. They only need to install the disconnector onto the main body of the insulating crossarm according to the predetermined connection method. This greatly saves manpower and time costs, while also reducing safety risks during the installation process.

[0032] The integrated design makes the overall structure of the equipment more compact, reducing the space it occupies. For substations or power lines with limited space, this design can better adapt to layout and planning requirements, improving space utilization.

[0033] Specifically, in some embodiments, such as Figure 5 As shown, the disconnector switch connection and fixing device 3 includes a left guide plate 6 and a right guide plate 7 arranged opposite to each other. An upper connecting plate 8, a middle connecting plate 9, and a lower connecting plate 10 are fixedly connected between the left guide plate 6 and the right guide plate 7. The upper connecting plate 8 has a first mounting hole 11, the middle connecting plate 9 has a second mounting hole 12, and the lower connecting plate 10 has a third mounting hole 13. The first mounting hole 11 is fixedly connected to a threaded slot 14. An operating bolt 15 passes through the second mounting hole 12 and the third mounting hole 13. The operating bolt 15 engages with the threaded slot 14 through threads.

[0034] The disconnector switch connection and fixing device 3 also includes a guide part 16, which includes a flared opening 17 formed by side plates. The guide part 16 is fixedly connected to the left guide plate 6 and the right guide plate 7, and the larger end of the flared opening 17 faces the installation direction of the disconnector switch 4.

[0035] In some embodiments, such as Figures 1-5The mounting part of the disconnect switch 4 includes a mounting horizontal plate 21 and a mounting vertical plate 22. The mounting horizontal plate 21 has through holes 23 corresponding to the positions of the first mounting hole 11, the second mounting hole 12, and the third mounting hole 13. The operating bolt 15 can pass through the through holes 23.

[0036] A positioning pin 24 is formed in the installation direction of the crossarm 2, and a positioning hole corresponding to the positioning pin 24 is provided on the mounting vertical plate.

[0037] In these embodiments, during specific installation operations, the operator aligns the mounting portion 5 of the disconnector switch 4 with the disconnector switch fixing device 3. During installation, the flared opening 17 of the guide portion 16 provides excellent guidance, allowing the mounting portion 5 to smoothly enter between the left guide plate 6 and the right guide plate 7. When the through hole 23 of the mounting plate 21 aligns with the first mounting hole 11 of the upper connecting plate 8, the second mounting hole 12 of the middle connecting plate 9, and the third mounting hole 13 of the lower connecting plate 10, the operating bolt 15 is sequentially passed through the second mounting hole 12, the through hole 23 of the mounting plate 21, and the third mounting hole 13, and engages with the threaded slot 14 that is fixedly connected to the first mounting hole 11. During operation, the operating ring 26 at the bottom of the operating bolt 14 facilitates rotation by the operator, while the washer on the operating bolt 15 increases the stability and sealing of the connection. Meanwhile, the positioning pin 24 on the crossarm 2 is inserted into the positioning hole 25 on the mounting plate, further ensuring the accuracy and stability of the disconnector switch 4 installation. This achieves the integrated installation of the insulating crossarm and the disconnector switch, fully leveraging the advantages of this equipment in simplifying the installation process and saving space. In subsequent use, if the disconnector switch needs to be inspected or replaced, simply reverse the above steps, unscrew the operating bolts, and the disconnector switch can be easily removed from the insulating crossarm body, facilitating maintenance and upkeep.

[0038] In some embodiments, such as Figures 1-5 As shown, a clamp 18 is fixedly connected to the middle of the crossarm 2. The clamp 18 includes a base 19 and an annular band 20. The base 19 is fixedly connected to the middle of the crossarm 2. The base 19 has round holes at both ends. The annular band 20 passes through the round holes and is fastened with bolts and nuts.

[0039] The clamp 18 is used to fix the integrated insulated crossarm disconnector to the utility pole or other supporting structure. This clamp 18 is designed with high flexibility and adaptability, and can be adjusted according to different supporting structure dimensions. In practical applications, workers can select an appropriate length and specification of the ring-shaped clamp 20 based on the specific conditions of the on-site supporting structure, and securely fix the clamp 18 to the supporting structure by adjusting the tightness of the bolts and nuts.

[0040] Furthermore, the fixed connection between the base 19 of the clamp 18 and the middle of the crossarm 2 further enhances the stability of the entire integrated insulated crossarm disconnector switch. The base 19 provides a stable support point for the crossarm 2, enabling it to maintain balance and stability when bearing the weight of the disconnector switch 4 and other auxiliary equipment. Simultaneously, the effective connection between the clamp 18 and the crossarm 2 disperses the vibrations and impacts generated during equipment operation onto the support structure, reducing damage to the equipment's structure and extending its service life.

[0041] During long-term use of the equipment, the clamp 18 also possesses certain corrosion resistance and wear resistance properties. The surface of the clamp 18 can be specially treated, such as galvanizing or painting, to resist external environmental erosion. During frequent tightening and loosening processes, the annular band 20, due to its good wear resistance, also ensures the reliability and stability of its connection.

[0042] Furthermore, the integrated design of the insulated crossarm disconnector facilitates equipment transportation and management. During transportation, the compact overall structure and small footprint make it easy to handle and unload. In terms of management, the reduced number of parts simplifies inventory management and lowers operating costs. Simultaneously, this integrated equipment allows for more organized placement and layout at the installation site, improving on-site management efficiency.

[0043] During the operation of a power system, the integrated insulated crossarm disconnector can quickly respond to system operation commands. When it is necessary to isolate or connect the circuit, the disconnector 4 can act rapidly, and due to its stable and accurate installation, it can ensure the reliability and safety of operation. Moreover, this device can be integrated and linked with other power equipment to realize automated control and intelligent management of the power system, further improving the operating efficiency and reliability of the power system.

[0044] When installing the disconnector switch 4, the operator aligns the mounting portion 5 of the disconnector switch 4 with the disconnector switch fixing device 3, using the flared opening 17 of the guide portion 16 to facilitate the insertion of the disconnector switch 4 into the installation position. Then, the operating bolt 15 is passed sequentially through the second mounting hole 12, the through hole 23 on the mounting portion 5, and the third mounting hole 13, engaging with the threaded slot 14 on the first mounting hole 11. By rotating the operating bolt 15, it is tightly connected to the threaded slot 14, thereby securely installing the disconnector switch 4 onto the insulating crossarm body 1.

[0045] The operating ring 26 at the bottom of the operating bolt 15 facilitates rotation by the operator, while the washer 27 passing through the operating bolt 15 acts as a buffer and prevents loosening, ensuring the stability of the connection. Meanwhile, the clamp 18 in the middle of the crossarm 2 secures the entire integrated insulated crossarm disconnector switch to a supporting structure such as a utility pole. The base 19 of the clamp 18 is fixedly connected to the crossarm 2, and the two ends of the annular band 20 pass through the round holes at both ends of the base 19 and are tightened with bolts and nuts, ensuring the stability of the equipment installation.

[0046] Furthermore, the positioning pin 24 on the crossarm 2 cooperates with the positioning hole 25 on the mounting plate 22, which can further improve the accuracy and stability of the installation of the disconnecting switch 4. During the installation process, the positioning pin 24 is inserted into the positioning hole 25, which restricts the horizontal movement of the disconnecting switch 4, so that the disconnecting switch 4 can be accurately installed in the predetermined position, ensuring the normal operation of the equipment.

[0047] This integrated design of the insulated crossarm disconnector not only demonstrates significant advantages during installation but also offers excellent operability in subsequent maintenance and repair. When maintenance or replacement of the disconnector 4 is required, workers only need to loosen the operating bolt 15 to remove the disconnector 4 from the insulated crossarm body 1, greatly improving work efficiency. Simultaneously, the integrated design reduces the number of parts, lowers the probability of failure, and improves the reliability and stability of the equipment, providing strong protection for the safe operation of the power system.

[0048] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. The above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
