Description

Technical Field

[0001] This invention relates to a conductive rod assembly and a through-core post insulator. Background Technology

[0002] A through-core post insulator is an insulating structural component used in load switches, a key component in prefabricated substations. For example... Figure 1 As shown, the through-core post insulator 13 is fixed to the frame 14 of the load switch by the mounting flange 15. The through-core post insulator 13 is provided with a conductive rod 12. The two ends of the conductive rod 12 are connected to conductive blocks 11. The conductive blocks 11 can connect the live conductors on both sides of the frame 14. The conductive rod 12 is insulated from the frame 14.

[0003] When connecting the aforementioned conductive rod to the conductive block, the conductive rod is first inserted into the countersunk hole of the conductive block, and then the two are welded together using a brazing process. However, the brazing process poses certain safety hazards and produces fumes, which is detrimental to the environment. Summary of the Invention

[0004] The purpose of this invention is to provide a conductive rod assembly to solve the technical problem that the conductive rod and conductive block are welded together by brazing in the prior art, which poses certain safety hazards; the purpose of this invention is also to provide a through-core post insulator.

[0005] To achieve the above objectives, the technical solution for the conductive rod assembly of the present invention is as follows:

[0006] Conductive rod assembly, including:

[0007] Conductive rod;

[0008] There are two conductive blocks, one at each end of the conductive rod.

[0009] A support plate is provided on the side of the conductive block facing the conductive rod. The support plate is provided with a support plate threaded hole and a support plate through hole. The support plate threaded hole is located at the center of the support plate, and at least two support plate through holes are arranged at intervals around the support plate threaded hole.

[0010] A tapered hole is provided on the side of the conductive block facing the support plate, and the size of the tapered hole at the end closer to the support plate is larger than the size of the end farther away from the support plate;

[0011] The end of the conductive rod is provided with a tapered section and a threaded section. The threaded section is threadedly connected to the threaded hole of the support plate, and the tapered section is fitted into the tapered hole.

[0012] The fastening bolt passes through the hole in the support plate and is threaded onto the conductive block, so that the conductive rod is pressed onto the conductive block by the support plate, thereby making the tapered section in close contact with the tapered hole.

[0013] The beneficial effects are as follows: During the assembly of the conductive rod assembly, the support plate is first screwed onto the threaded section of the conductive rod, and then the tapered section of the conductive rod and the tapered hole of the conductive block are inserted and fitted together. Next, the fastening bolt is passed through the support plate hole on the support plate and threaded onto the conductive block. The tightening force of the fastening bolt causes the support plate to move relative to the conductive block, which in turn causes the support plate to press the conductive rod tightly against the conductive block, ensuring close contact between the tapered section and the tapered hole, forming a pressurized conductive surface, and guaranteeing a reliable conductive connection between the conductive rod and the conductive block. Compared to brazing, this process is simpler and safer, and does not produce harmful gases, thus being environmentally friendly.

[0014] As a further improvement, the support plate perforation is an elongated hole extending circumferentially along the support plate.

[0015] The beneficial effects are: this design not only reduces weight, but also facilitates the alignment with the connection holes on the conductive block, making it easier to install the fastening bolts.

[0016] As a further improvement, the tapered hole is a circular tapered hole.

[0017] The beneficial effects are: this design eliminates sharp edges within the tapered hole, preventing tip discharge. Furthermore, it facilitates tight contact between the tapered hole and the tapered section, further improving conductivity reliability.

[0018] As a further improvement, the conductive block is an aluminum block, and / or the conductive rod is an aluminum rod.

[0019] The benefits are: compared to copper conductive blocks and rods, they are cheaper and lighter, reducing costs while ensuring reliable conductivity.

[0020] As a further improvement, the support disk is a metal disk.

[0021] The beneficial effect is to ensure the strength of the support plate.

[0022] To achieve the above objectives, the technical solution of the through-core post insulator of the present invention is as follows:

[0023] A through-core post insulator includes an insulator and a conductive rod assembly, the conductive rod assembly comprising:

[0024] Conductive rod;

[0025] There are two conductive blocks, one at each end of the conductive rod.

[0026] A support plate is provided on the side of the conductive block facing the conductive rod. The support plate is provided with a support plate threaded hole and a support plate through hole. The support plate threaded hole is located at the center of the support plate, and at least two support plate through holes are arranged at intervals around the support plate threaded hole.

[0027] A tapered hole is provided on the side of the conductive block facing the support plate, and the size of the tapered hole at the end closer to the support plate is larger than the size of the end farther away from the support plate;

[0028] The end of the conductive rod is provided with a tapered section and a threaded section. The threaded section is threadedly connected to the threaded hole of the support plate, and the tapered section is fitted into the tapered hole.

[0029] The fastening bolt passes through the hole in the support plate and is threaded onto the conductive block, so that the conductive rod is pressed onto the conductive block by the support plate, thereby making the tapered section in close contact with the tapered hole.

[0030] The beneficial effects are as follows: During the assembly of the conductive rod assembly, the support plate is first screwed onto the threaded section of the conductive rod, and then the tapered section of the conductive rod and the tapered hole of the conductive block are inserted and fitted together. Next, the fastening bolt is passed through the support plate hole on the support plate and threaded onto the conductive block. The tightening force of the fastening bolt causes the support plate to move relative to the conductive block, which in turn causes the support plate to press the conductive rod tightly against the conductive block, ensuring close contact between the tapered section and the tapered hole, forming a pressurized conductive surface, and guaranteeing a reliable conductive connection between the conductive rod and the conductive block. Compared to brazing, this process is simpler and safer, and does not produce harmful gases, thus being environmentally friendly.

[0031] As a further improvement, the support plate perforation is an elongated hole extending circumferentially along the support plate.

[0032] The beneficial effects are: this design not only reduces weight, but also facilitates the alignment with the connection holes on the conductive block, making it easier to install the fastening bolts.

[0033] As a further improvement, the tapered hole is a circular tapered hole.

[0034] The beneficial effects are: this design eliminates sharp edges within the tapered hole, preventing tip discharge. Furthermore, it facilitates tight contact between the tapered hole and the tapered section, further improving conductivity reliability.

[0035] As a further improvement, the conductive block is an aluminum block, and / or the conductive rod is an aluminum rod.

[0036] The benefits are: compared to copper conductive blocks and rods, they are cheaper and lighter, reducing costs while ensuring reliable conductivity.

[0037] As a further improvement, the support disk is a metal disk.

[0038] The beneficial effect is to ensure the strength of the support plate. Attached Figure Description

[0049] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0050] Embodiment 1 of the through-core post insulator of the present invention:

[0051] like Figure 2 As shown, the through-core post insulator 25 includes an insulator and a conductive rod assembly, which are injection molded together with the insulator. A mounting flange 27 is provided on the insulator, and the through-core post insulator 25 is fixed to the frame 26 of the load switch via the mounting flange 27.

[0052] In this embodiment, the conductive rod assembly includes a conductive rod 24, a conductive block 21, and a support plate 22. Two conductive blocks 21 and two support plates 22 are provided. The two conductive blocks 21 are respectively provided at both ends of the conductive rod 24 to connect the charged conductors on both sides of the frame 26. The conductive rod 24 is insulated from the frame 26.

[0053] like Figure 2 , Figure 4 and Figure 5 As shown, the support plate 22 is disposed on the side of the conductive block 21 facing the conductive rod 24. The support plate 22 is provided with a support plate threaded hole 31 and a support plate through hole 32. The support plate threaded hole 31 is located at the center of the support plate 22, and four support plate through holes 32 are arranged at intervals around the support plate threaded hole 31. In other embodiments, the number of support plate through holes can be set as needed.

[0054] like Figure 2 and Figure 3As shown, a tapered hole 30 is provided on the side of the conductive block 21 facing the support disk 22. The size of the end of the tapered hole 30 near the support disk 22 is larger than the size of the end of the tapered hole 30 away from the support disk 22. In this embodiment, the tapered hole 30 is located at the center of the conductive block 21. The conductive block 21 is also provided with conductive block connecting holes 28, which are threaded holes. The conductive block connecting holes 28 correspond one-to-one with the support disk through holes 32, that is, four conductive block connecting holes 28 are arranged at intervals around the tapered hole 30. Among them, the conductive block connecting holes 28 are through holes.

[0055] In this embodiment, the bottom of the tapered hole 30 is also provided with a conductive block threaded hole 29, and the tapered hole 30 and the conductive block threaded hole 29 together constitute the central hole of the conductive block 21.

[0056] like Figure 2 As shown, the end of the conductive rod 24 is provided with a tapered section and a threaded section. The threaded section is threadedly connected to the threaded hole 31 of the support plate, and the tapered section is adapted to be inserted into the tapered hole 30. It also includes a fastening bolt 23, which passes through the through hole 32 of the support plate and is threadedly connected to the conductive block connection hole 28 of the conductive block 21, so as to press the conductive rod 24 onto the conductive block 21 through the support plate 22, thereby making the tapered section and the tapered hole 30 in close contact, ensuring a reliable conductive connection between the conductive rod 24 and the conductive block 21. Compared with the brazing process, the operation is simple and safe, and no harmful gases are generated, which is beneficial to the environment.

[0057] In this embodiment, the conductive block 21 is an aluminum block and the conductive rod 24 is an aluminum rod. Compared with the conductive block 21 and conductive rod 24 made of copper, they are cheaper and lighter, reducing costs while ensuring reliable conductivity.

[0058] In this embodiment, the support plate through hole 32 is an elongated hole extending along the circumference of the support plate. This design not only reduces weight but also facilitates the correspondence with the conductive block connection hole 28, making it easier to install the fastening bolt 23.

[0059] In this embodiment, the conical hole 30 is a conical hole. This design eliminates sharp edges within the conical hole, preventing tip discharge. Furthermore, it facilitates close contact between the conical hole and the conical segment, further improving conductivity reliability.

[0060] In this embodiment, the support disk 22 is a metal disk to ensure the strength of the support disk 22.

[0061] During the assembly of the conductive rod assembly, taking one end of the conductive rod 24 as an example, first screw the support plate 22 onto the threaded section of the conductive rod 24, and then insert the tapered section of the conductive rod 24 into the tapered hole 30 of the conductive block 21; then, pass the fastening bolt 23 through the support plate through hole 32 on the support plate 22 and screw it into the corresponding conductive block connection hole 28 on the conductive block 21; then, tighten the fastening bolt 23 one by one, so that the locking force of the fastening bolt 23 drives the support plate 22 to move relative to the conductive block 21, and then the support plate 22 drives the conductive rod 24 to press against the conductive block 21, so that the tapered section and the tapered hole 30 are in close contact, forming a pressure conductive surface, ensuring a reliable conductive connection between the conductive rod 24 and the conductive block 21.

[0062] Embodiment 2 of the through-core post insulator of the present invention:

[0063] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the support plate through hole 32 is an elongated hole extending circumferentially along the support plate 22 to ensure that the support plate through hole 32 corresponds to the conductive block connection hole 28. In this embodiment, the support plate through hole is a circular hole, and the diameter of the circular hole is larger than the diameter of the conductive block connection hole to ensure that the support plate through hole corresponds to the conductive block connection hole.

[0064] Embodiment 3 of the through-core post insulator of the present invention:

[0065] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the tapered hole 30 is a conical hole. In this embodiment, the tapered hole is a pyramidal hole.

[0066] Embodiment 4 of the through-core post insulator of the present invention:

[0067] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the conductive block is an aluminum block and the conductive rod is an aluminum rod. In this embodiment, the conductive block is a copper block and the conductive rod is an aluminum rod. In other embodiments, the conductive block can be an aluminum block and the conductive rod can be a copper rod.
