Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass insulator technology, and in particular to a disc-shaped suspension glass insulator. Background Technology
[0002] A device used to support and insulate conductors is called an insulator. If the insulator is made of glass, it is called a glass insulator. Glass insulators are mainly used in high-voltage, ultra-high-voltage, and extra-high-voltage AC and DC transmission lines for insulating and suspending conductors. They are also easy to inspect, have good arc and vibration resistance, are not prone to aging, have large capacitance, and provide uniform voltage distribution in series.
[0003] The structure of a disc suspension glass insulator includes steel feet, a steel cap, and glass insulation. It is one of the most widely used insulators in power transmission lines.
[0004] However, the glass used in disc suspension glass insulators is more brittle than porcelain insulators. It is prone to breakage when subjected to external impact or overload. Furthermore, since the glass used in glass insulators is mostly tempered glass, when it breaks, it will form small fragments that scatter everywhere, which can easily injure people working on high-voltage lines. Utility Model Content
[0005] The purpose of this invention is to provide a new type of glass insulator that is easy to assemble and disassemble. By setting an adhesive layer, it can effectively bond the fragments when the glass insulator breaks, preventing the fragments from scattering and causing injury to workers.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] A disc-shaped suspension glass insulator includes a glass insulator, a steel foot, and a steel cap; the glass insulator includes a first glass insulator, a second glass insulator, an adhesive layer disposed between the two, hollow arc-shaped plates commonly fitted on the opposite sides of the first and second glass insulators, and a connecting assembly connecting the two hollow arc-shaped plates.
[0008] Preferably, the connecting assembly includes connecting plates respectively disposed at both ends of each of the hollow arc-shaped plates, and a first screw connecting the two compatible connecting plates.
[0009] Preferably, the inner wall of the hollow arc-shaped plate is provided with a buffer sheet, and the buffer sheet and the inner wall of the hollow arc-shaped plate are in close contact with each other.
[0010] Preferably, the buffer sheet is a first polytetrafluoroethylene sheet.
[0011] Preferably, the ends of the two hollow arc-shaped plates are spaced apart.
[0012] Preferably, the outer wall of the glass insulator is provided with two semi-circular connecting steel rings, the openings of the two connecting steel rings are connected by a second screw, and the connecting steel rings are in close contact with the outer wall of the glass insulator.
[0013] Preferably, a second polytetrafluoroethylene (PTFE) sheet is disposed between the connecting steel ring and the glass insulator, and the second PTFE sheet is in contact with the outer wall of the glass insulator; the first PTFE sheet and the connecting steel ring are in contact with each other.
[0014] Preferably, the top surface of the glass insulator is provided with a hydrophobic layer.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] By setting an adhesive layer between the first and second glass insulators, the fragments can be effectively bonded together when the glass insulator breaks, preventing the fragments from scattering and causing injury to workers, thus effectively improving the safety of the glass insulator during use.
[0017] By fitting a hollow arc-shaped plate onto each of the opposite edges of the first and second glass insulators, and by providing a connecting assembly that connects the two hollow arc-shaped plates, the first and second glass insulators can be further fixed together through the synergistic effect of the two hollow arc-shaped plates and the connecting plate. This avoids the technical problem that the tensile strength of the glass insulators is reduced after changing the independent glass insulators to combined glass insulators, which would easily cause the first and second glass insulators to detach, thus having an extremely adverse impact on the operation of disc suspension glass insulators.

[0023] Example 1
[0024] In the existing technology, the glass used in the insulating parts of disc suspension glass insulators is more brittle than that used in porcelain insulators. Once subjected to external impact or overload, it is easy to break. Moreover, since the glass used in glass insulators is mostly tempered glass, when it breaks, it will form small fragments that scatter everywhere, which can easily injure people working in high-voltage lines.
[0025] Based on this, the present invention provides a disc-shaped suspension glass insulator, such as... Figure 1-2 As shown, it includes a glass insulator, a steel foot 1, and a steel cap 2; the glass insulator includes a first glass insulator 3, a second glass insulator 4, and an adhesive layer 5 disposed between them (wherein, the adhesive layer 5 uses the adhesive used in existing laminated glass, such as PVB adhesive, which is insulating and has excellent adhesion), and is together fitted onto hollow arc-shaped plates 6 (e.g., ...) on the opposite sides of the first glass insulator 3 and the second glass insulator 4. Figure 1-3 As shown), and the connecting assembly that connects the two hollow arc-shaped plates 6. Figure 1 As shown, the cross-sectional view and end face of the hollow arc-shaped plate 6 are both U-shaped. Figure 1-2 As shown, the two hollow arc-shaped plates 6 are symmetrically arranged on the edge of the glass insulator.
[0026] like Figure 2 As shown, the connecting assembly further includes connecting plates 7 respectively disposed at both ends of each of the hollow arc-shaped plates 6, and a first screw 8 connecting the two compatible connecting plates 7.
[0027] Working principle: By setting an adhesive layer 5 between the first glass insulator 3 and the second glass insulator 4, when the glass insulator breaks, the glass fragments are stuck together by the adhesive layer 5, making the cracks radial and maintaining their original shape and visibility to the greatest extent. This effectively avoids glass punctures, scratches, and scattering. Even when the glass insulator breaks, the adhesive layer 5 can still effectively stick the fragments together, thus preventing the fragments from scattering and causing injury to workers, effectively improving the safety of the glass insulator during use.
[0028] By fitting a hollow arc-shaped plate 6 onto each of the opposite edges of the first glass insulator 3 and the second glass insulator 4, the U-shaped structure of the hollow arc-shaped plate 6 can clamp the first and second glass insulators, effectively improving their tensile strength. By connecting the two hollow arc-shaped plates 6 with a first screw 8, they can be fixed to the first glass insulator 3 and the second glass insulator 4. This effectively avoids the technical problem that changing the independent glass insulators in the prior art to a combined glass insulator would reduce the tensile strength of the glass insulators, leading to easy detachment between the first glass insulator 3 and the second glass insulator 4, which would have a severely adverse impact on the operation of the disc-type suspension glass insulator.
[0029] Example 2
[0030] Based on Example 1, such as Figure 1 and Figure 3 As shown, a buffer sheet 9 is provided on the inner wall of the hollow arc-shaped plate 6. The buffer sheet 9 and the inner wall of the hollow arc-shaped plate 6 are in close contact, i.e., the cross-section is also U-shaped. By providing the buffer sheet 9, hard collisions between the hollow arc-shaped plate 6 and the first and second glass insulating components can be effectively avoided, thus preventing the glass insulating components from increasing the risk of breakage due to wear. Furthermore, the buffer sheet 9 is a first polytetrafluoroethylene (PTFE) sheet. PTFE sheets have a certain cushioning effect and are highly resistant to acids, alkalis, and corrosion.
[0031] Furthermore, such as Figure 1-2 As shown, a gap is provided between the ends of the two hollow arc-shaped plates 6. The gap facilitates the drainage of rainwater or dirt along the gap, improving the cleanliness of the top surface of the glass insulation component.
[0032] Example 3
[0033] Based on Example 2, such as Figure 1-2 and Figure 4 As shown, the outer wall of the glass insulator is provided with two semi-circular connecting steel rings 10. The openings of the two connecting steel rings 10 are connected by a second screw 13, and the connecting steel rings 10 are in close contact with the outer wall of the glass insulator. In this solution, by providing the connecting steel rings 10, the outer wall of the glass insulator can be protected, preventing rainwater from soaking the adhesive layer 5 for a long time, which could cause the adhesive layer 5 to detach, or preventing sunlight from aging the adhesive layer 5 and reducing its bonding effect. This is especially important for the sidewalls of the glass insulator that are not covered by the two hollow arc-shaped plates 6.
[0034] Furthermore, in actual implementation, the fit between the connecting steel ring 10 and the side wall of the glass insulator is not very tight. Rainwater from the outside or from the top surface of the glass insulator may flow into the gap between the connecting steel ring 10 and the glass insulator, causing the rainwater to come into contact with the adhesive layer 5 and adversely affecting the bonding effect of the adhesive layer 5. Therefore, if... Figure 1-2 and Figure 4 As shown, a second polytetrafluoroethylene (PTFE) sheet 11 is disposed between the connecting steel ring 10 and the glass insulating component, and the second PTFE sheet 11 is in contact with the outer wall of the glass insulating component; the first PTFE sheet and the connecting steel ring 10 are in contact with each other. Because the second PTFE sheet 11 has a certain buffering function, it can achieve a tight fit with the outer wall of the glass insulating component through a certain deformation, thereby making it difficult for rainwater to flow into the gap between the two, effectively protecting the adhesive layer 5.
[0035] Furthermore, the top surface of the glass insulator is provided with a hydrophobic layer made of polytetrafluoroethylene, which is not only resistant to acids and alkalis but also has extremely strong hydrophobicity to prevent rainwater from accumulating.
