Description

Technical Field

[0001] This utility model relates to the field of insulator technology, specifically to a ceramic insulator for power towers. Background Technology

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a component at ground potential. It can withstand voltage and mechanical stress. Insulators are usually made of ceramic, glass or composite materials. Ceramic insulators are used in the installation of high-voltage transmission lines on power towers. They have high resistivity, high dielectric strength and good mechanical properties to ensure the insulation safety of power transmission.

[0003] Existing insulators have limited practicality when installed with external connecting posts due to the varying sizes of the posts, and are susceptible to damage from prolonged exposure. Therefore, a ceramic insulator for power towers is proposed to facilitate installation with different connecting posts, improve stability, simplify installation and replacement, and provide some protection against damage from sand and gravel. Summary of the Invention

[0004] In view of the shortcomings of the above-mentioned background technology, the purpose of this utility model is to provide a ceramic insulator for power towers, which is easy to install on different connecting columns, improves stability, facilitates installation and replacement, and at the same time provides a certain degree of protection for its appearance to avoid damage from sand and gravel.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: a ceramic insulator for a power tower, comprising a transmission pole, an arc-shaped fixing frame, an insulator string and an arc-shaped protective net, wherein the transmission pole is provided with arc-shaped fixing frames on both sides of the top, and mounting plates are provided on both sides of the arc-shaped fixing frames, and a concave connecting frame is provided on one side of the mounting plate;

[0006] A connector and an insulator string are respectively provided on one side of the concave connecting frame. A disc is provided on both sides of the insulator string, and an arc-shaped protective net is provided between the corresponding discs around the insulator string.

[0007] Specifically, the mounting plate has an anti-slip pad on its inner side, and a fastening bolt passes through the reserved opening on one side of the mounting plate corresponding to the side of the concave connecting frame.

[0008] Specifically, a connecting pipe is welded to one side of the concave connecting frame, and the connecting pipe is threadedly connected to the connector.

[0009] Specifically, the connectors pass through the reserved openings in the insulator string and the center of the disc, respectively.

[0010] Specifically, a fixing plate is provided at both ends of one side of the disc, and a tightening bolt passes through a reserved opening on one side of the fixing plate. One end of the tightening bolt is fixed to the limiting plate by a screw.

[0011] Specifically, slots are provided on the outer periphery of the other side of the disc, and the slots engage with the arc-shaped protective net. The arc-shaped protective net has mounting ears at both ends, and connecting bolts pass through the top of the mounting ears via pre-reserved openings.

[0012] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0013] This utility model discloses a ceramic insulator for a power tower. Rotating and tightening the bolts causes the insulator string to move towards the center, facilitating the fixing of the insulator string to connectors of different sizes, thus improving installation stability and practicality. Simultaneously, rotating the concave connecting frame adjusts the angle of the insulator string. The fastening bolts pass through the mounting plate and the concave connecting frame, connecting to the mounting plate and securing it to both sides of the transmission pole. This allows for flexible installation on the tower body and ensures stable connection with the transmission pole's tie rods, facilitating easy disassembly and assembly later. Furthermore, the ceramic insulator for this power tower further encases the insulator string by securing two sets of arc-shaped protective nets at both ends within slots. Rotating the connecting bolts then fixes the arc-shaped protective nets in place, providing protection against external damage. Attached Figure Description

[0023] In use, the insulator string 9 is installed between the discs 10, and the insulator string 9 is connected to the external connector through the connector 8, and installed on one side of the concave connecting frame 6;

[0024] Then rotate and tighten bolt 12 to move it towards the center, so as to facilitate the fixing of insulator string 9 with connectors of different sizes, thereby improving the stability during installation and enhancing practicality;

[0025] Rotate the concave connecting frame 6 to adjust the angle of the insulator string 9. The fastening bolt 5 passes through the mounting plate 3 and the concave connecting frame 6 and connects with the mounting plate 3. The mounting plate 3 is then fixed around both sides of the transmission pole 1, allowing it to be flexibly installed on the tower body. At the same time, it can also ensure the stability of the diagonal connection with the transmission pole 1 and facilitate easy disassembly and assembly later.

[0026] The two sets of arc-shaped protective nets 15 are inserted into the slots 14 to wrap the insulator string 9. Then, the connecting bolts 17 are rotated to fix the arc-shaped protective nets 15 in place, so as to provide some protection and prevent them from being damaged by the outside world.

[0033] When in use, rotating and tightening bolt 12 causes the insulator string 9 to move towards the center, which facilitates fixing the insulator string 9 to connectors of different sizes, thereby improving the stability during installation and enhancing its practicality.

[0034] For example, such as Figure 1 , Figure 3 , Figure 4 As shown, the present invention also includes slots 14 on the outer periphery of the other side of the disc 10, which engage with the arc-shaped protective net 15. The arc-shaped protective net 15 has mounting ears 16 at both ends, and connecting bolts 17 pass through the pre-reserved openings at the top of the mounting ears 16.

[0035] When in use, the two ends of the two sets of arc-shaped protective nets 15 are inserted into the slots 14 to wrap the insulator string 9, and then the connecting bolts 17 are rotated to fix the arc-shaped protective nets 15 in place, so as to provide a certain degree of protection and prevent them from being damaged by the outside world.

[0036] In use, the insulator string 9 is installed between the discs 10, and the insulator string 9 is connected to the external connector through the connector 8, and installed on one side of the concave connecting frame 6.

[0037] Then rotate and tighten bolt 12 to move it towards the center, so as to facilitate the fixing of insulator string 9 with connectors of different sizes, thereby improving the stability during installation and enhancing practicality;

[0038] Rotate the concave connecting frame 6 to adjust the angle of the insulator string 9. The fastening bolt 5 passes through the mounting plate 3 and the concave connecting frame 6 and connects with the mounting plate 3. The mounting plate 3 is then fixed around both sides of the transmission pole 1, allowing it to be flexibly installed on the tower body. At the same time, it can also ensure the stability of the diagonal connection with the transmission pole 1 and facilitate easy disassembly and assembly later.

[0039] The two sets of arc-shaped protective nets 15 are inserted into the slots 14 to wrap the insulator string 9. Then, the connecting bolts 17 are rotated to fix the arc-shaped protective nets 15 in place, so as to provide some protection and prevent them from being damaged by the outside world.
