[0002] In the field of modern power equipment, gas-insulated metal-enclosed switchgear (GIS) is widely used in power facilities such as substations due to its advantages such as small size, high reliability, and convenient maintenance. During the assembly of GIS equipment, the accuracy of the installation position of the conductor contacts has a critical impact on the performance of the GIS equipment. When the conductor contacts are connected to the insulators, ensuring their precise relative positions is the foundation for the normal operation of the GIS equipment. The existing assembly process mainly relies on manual observation to determine the relative positions of the conductor contacts and insulators, and then fixes them with bolts. Due to the lack of effective positioning methods, it is difficult to guarantee the assembly accuracy of the conductor contacts and insulators, which leads to an increase in the contact resistance between the conductor contacts and the connected conductors, affecting the normal operation of the GIS equipment.

In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0030] This application proposes an auxiliary positioning device for conductor contact mounting, suitable for providing positioning support for conductor contact 410 when it is fixed to insulator 420; such as Figures 1 to 5 As shown, the system includes: a support assembly, a positioning plate 200, and a positioning cone nut 140 arranged opposite to each other; both ends of the positioning plate 200 are located at the top of the two support assemblies; each support assembly includes: a support column 110 and a base 120; the base 120 has oppositely opened fixing holes, and the fixing holes are matched with the studs 421 on the insulator 420 to pass through the fixing holes; the positioning cone nut 140 is sleeved on the studs 421 on the insulator 420 and is tightly fitted to the side of the base 120 away from the insulator 420; one end of the support column 110 is located on the base 120, and the support column 110 is located between the two fixing holes; the end of the positioning plate 200 is installed on the end of the support column 110 away from the base 120, and the length direction of the positioning plate 200 is perpendicular to the length direction of the support column 110; the positioning plate 200 has a positioning hole, which is used to position the conductor contact 410 when it is inserted into the positioning hole.

[0031] It should be noted that the base 120 provides a stable support foundation for the support column 110 and the positioning plate 200. The base 120 engages with the stud 421 on the insulator 420 through fixing holes, thereby fixing the auxiliary positioning device of this application onto the insulator 420. The connection between the base 120 and the insulator 420 determines the position of the positioning device relative to the insulator 420, thereby indirectly determining the position of the conductor contact 410 relative to the insulator 420, ensuring the accuracy and reliability of the installation. The positioning cone nut 140 matches the stud 421 of the insulator 420. The positioning cone nut 140 is sleeved on the stud 421 of the insulator 420 and fits tightly against the base 120, thereby firmly fixing the base 120 onto the insulator 420 and preventing the base 120 from loosening during installation or use. The length direction of the support column 110 is perpendicular to the plane on which the base 120 is located. The positioning plate 200 is detachable via the support column 110. The conductor contact 410 is mounted on the base 120. The design of the support column 110 being perpendicular to the positioning plate 200 and the base 120 avoids positional deviation of the positioning plate 200 due to the tilt of the support column 110, allowing the positioning plate 200 to position the conductor contact 410 on a stable horizontal plane. The length of the support column 110 is designed according to actual assembly requirements, ensuring both a suitable distance between the positioning plate 200 and the insulator 420 for smooth installation of the conductor contact 410 and sufficient stability of the positioning plate 200. The positioning hole matches the outer contour of the conductor contact 410. After the conductor contact is inserted into the positioning hole, it contacts the insulator 420. The positioning hole on the positioning plate 200 is used to provide accurate positioning for the conductor contact 410, ensuring that the conductor contact is in the correct position when installed with the insulator 420, improving the accuracy of the conductor contact installation with the insulator 420, and thus ensuring the fitting accuracy of the conductor contact 410 and the connected conductor.

[0032] When it is necessary to install the conductor contact 410 and the insulator 420, firstly, the stud 421 on the insulator 420 is passed through the fixing hole on the base 120, and the positioning cone nut 140 is put on the stud 421. By tightening the positioning cone nut 140, the positioning device of this application is fixed on the insulator 420. Then, the connecting end of the conductor contact 410 is aligned with the positioning hole on the positioning plate 200 and inserted into the positioning hole, thereby achieving accurate positioning of the conductor contact 410 when connected to the insulator 420. After the conductor contact 410 is inserted into the positioning hole and the position is confirmed to be accurate, the conductor contact 410 and the insulator 420 can be finally fixed by bolts 130 and other connecting parts according to the conventional assembly process.

[0033] By working together with the support components, positioning plate 200, and positioning cone nut 140, the conductor contact 410 can be accurately positioned and supported. This effectively solves the problem of difficulty in ensuring assembly accuracy caused by manual observation in the existing assembly process, ensuring the relative position and assembly accuracy of the conductor contact 410 and the insulator 420, reducing the contact resistance between the conductor contact 410 and the connected conductor, and ensuring the normal operation of the GIS equipment. The positioning device of this application is easy to operate. The operator only needs to install the base 120 on the insulator 420 and then insert the conductor contact 410 into the positioning hole to complete the positioning process. No complicated operating skills or professional tools are required, which greatly improves the assembly efficiency. Moreover, the positioning device of this application has a simple and robust structure, can be reused, and has low processing cost.

[0034] In one possible implementation, such as Figure 4 As shown, the positioning plate 200 includes two connecting parts 210 and a positioning part 220. The main body of the positioning part 220 is a plate-shaped structure with rounded triangular corners. One end of one connecting part 210 is connected to the rounded corner of the positioning part 220, and one end of the other connecting part 210 is connected to the side of the positioning part 220. The two connecting parts 210 are coaxially arranged. A positioning hole is provided on the positioning part 220. It should be noted that the rounded triangular design allows the positioning part 220 to provide stable positioning support for the conductor contact 410 within a limited space, effectively utilizing space and making the positioning device more compact. The two coaxially arranged connecting parts 210 are connected to the positioning part 220 respectively, so that the force received by the positioning part 220 can be evenly transmitted to the support column 110 through the connecting parts 210. This avoids the positioning part 220 from tilting due to uneven force, thereby ensuring the positional accuracy of the positioning hole and ensuring that the conductor contact 410 is installed in place.

[0035] Furthermore, such as Figure 4 As shown, the two connecting parts 210 are provided with a relief part 211 at the end opposite to the positioning part 220. The design of the relief part 211 provides operating space for the operator when tightening the positioning cone nut 140, so that the operator can more easily align the tool with the positioning cone nut 140 to tighten or loosen it, which significantly improves work efficiency.

[0036] In one possible implementation, the positioning plate 200 is made of aluminum, which has low density and light weight, making it easy for installers to handle and operate, while also having good corrosion resistance.

[0037] In one possible implementation, there are two or more positioning holes; the centers of the two or more positioning holes are all equidistant from the center of the positioning part 220. It should be noted that multiple positioning holes can position the conductor contact 410 from multiple points, thereby improving the accuracy and consistency of installation. The multiple positioning holes are evenly distributed on a circumference centered on the center of the positioning part 220, making the supporting force on the conductor contact 410 more uniform during installation, ensuring the relative position and assembly accuracy of the conductor contact 410 and the insulator 420.

[0038] Preferably, there are three positioning holes.

[0039] In one possible implementation, such as Figure 1 , Figure 2 As shown, it also includes a positioning sleeve 300; the positioning sleeve 300 is disposed on the positioning plate 200, and the side of the positioning sleeve 300 facing the positioning plate 200 extends into the positioning hole. It should be noted that the inner diameter of the positioning sleeve 300 extending into the positioning hole matches the outer diameter of the conductor contact 410. The positioning sleeve 300 is used to position and guide the conductor contact 410, further reducing the shaking and offset of the conductor contact 410 during installation, ensuring that the conductor contact 410 is installed in the accurate position; at the same time, the positioning sleeve 300 can prevent the edge of the positioning hole from being worn or deformed due to frequent friction or collision with the conductor contact 410, and can also prevent the conductor contact 410 from being scratched when inserted into the positioning hole, thus extending the service life of the positioning plate 200 and the conductor contact 410.

[0040] In one possible implementation, such as Figure 5 As shown, the positioning sleeve 300 includes a fixing part 310 and a positioning guide part 320; the fixing part 310 is detachably disposed on the positioning plate 200 and is arranged around the positioning hole in the circumferential direction; one end of the positioning guide part 320 is fixedly connected to the fixing part 310, and one end of the positioning guide part 320 is disposed through the positioning hole.

[0041] It should be noted that the main body of the fixing part 310 is a circular plate-like structure. The fixing part 310 is tangentially arranged to the side of the positioning part 220. One end of the positioning guide part 320 is fixedly connected to the fixing part 310, and the fixing part 310 and the positioning guide part 320 are coaxially arranged. The fixing part 310 has a through hole, and correspondingly, the positioning plate 200 has a first threaded hole. The fixing bolt 130 passes through the through hole on the fixing part 310 and is connected to the first threaded hole of the positioning plate 200. The fixing part 310 is suitable for firmly installing the positioning guide part 320 in the positioning hole of the positioning plate 200, so that... The entire positioning device forms a stable structure, thereby preventing relative displacement or shaking of the positioning guide 320 during use. The positioning guide 320 provides precise guidance for the installation of the conductor contact 410, ensuring that the conductor contact 410 can be accurately installed in the predetermined position along the direction of the positioning guide 320. At the same time, the positioning guide 320 restricts the radial and circumferential movement of the conductor contact 410 in the positioning hole to a certain extent, enhancing the positioning stability of the conductor contact 410 and ensuring the relative position of the conductor contact 410 and the insulator 420 and their installation accuracy.

[0042] In one possible implementation, the positioning sleeve 300 is made of nylon. It should be noted that the self-lubricating properties of nylon reduce the friction between the conductor contact 410 and the positioning sleeve 300 when the conductor contact 410 is inserted. This allows the conductor contact 410 to pass smoothly through the positioning sleeve 300, reducing resistance during installation and making the installation operation easier and more convenient. Simultaneously, the wear-resistant properties of nylon allow it to withstand frequent friction during insertion and removal of the conductor contact 410, effectively reducing wear during installation and extending the service life of the positioning device.

[0043] In one possible implementation, such as Figure 1 As shown, it also includes bolt 130; bolt 130 passes through positioning plate 200 and support column 110 in sequence and is threadedly connected to base 120. It should be noted that the support column 110 has a connecting hole, which is a through hole that passes through the support column 110 and is set along the length of the support column 110. Correspondingly, the base 120 has a second threaded hole, which is coaxial with the connecting hole and matches bolt 130. Bolt 130 passes through the connecting hole on positioning plate 200 and support column 110 in sequence and is threadedly connected to the second threaded hole on base 120. By tightening bolt 130, positioning plate 200, support column 110 and base 120 are fixed together.

[0044] Furthermore, the second threaded hole on the base 120 is a countersunk hole. When the bolt 130 is screwed into the countersunk hole, the end of the bolt 130 connected to the base 120 is flush with or slightly lower than the surface of the base 120, thereby preventing the bolt 130 from penetrating through the base 120 and directly contacting and colliding with the insulator 420, which would cause scratches or damage to the insulator 420.
